WEBVTT - TechStuff Classic: TechStuff Leaps Into Hyperspace

0:00:04.240 --> 0:00:07.240
<v Speaker 1>Welcome to tex Stuff, a production of I Heart Radios

0:00:07.320 --> 0:00:13.600
<v Speaker 1>How Stuff Works. Hey there, and welcome to tech Stuff.

0:00:13.640 --> 0:00:16.560
<v Speaker 1>I'm your host, Jonathan Strickland. I'm an executive producer with

0:00:16.600 --> 0:00:20.239
<v Speaker 1>I Heart Radio and I love all things tech And

0:00:20.400 --> 0:00:22.720
<v Speaker 1>with time for us to listen to another classic episode,

0:00:22.720 --> 0:00:25.200
<v Speaker 1>it means it's a Friday, so let's all enjoy ourselves

0:00:25.200 --> 0:00:28.600
<v Speaker 1>and and dive back into the archives of tech Stuff.

0:00:28.640 --> 0:00:31.200
<v Speaker 1>You know, I've got more than episodes at this point,

0:00:31.280 --> 0:00:34.440
<v Speaker 1>so some of these are probably brand new to you guys.

0:00:34.680 --> 0:00:38.920
<v Speaker 1>This episode originally aired on April two, thousand thirteen. It

0:00:39.040 --> 0:00:43.400
<v Speaker 1>is called tex Stuff Leaps into hyper Space. Let's listen.

0:00:44.920 --> 0:00:47.360
<v Speaker 1>Red leather, yellow leather, red, yellow leather. All right, here

0:00:47.400 --> 0:00:51.360
<v Speaker 1>we go, Han Solo, I'm captain of the Millennium Falcon.

0:00:51.680 --> 0:00:53.519
<v Speaker 1>Chewy here tells me you're looking for passage to the

0:00:53.520 --> 0:00:57.440
<v Speaker 1>Alton System. Yes, indeed, if it's a fast ship fast ship,

0:00:57.600 --> 0:01:00.280
<v Speaker 1>you've never heard of the Millennium Falcon ship I have.

0:01:00.520 --> 0:01:02.200
<v Speaker 1>It's the ship that made the Kessel run in less

0:01:02.200 --> 0:01:05.240
<v Speaker 1>than twelve par secs. I've outrun Imperial starships. Not the

0:01:05.280 --> 0:01:08.040
<v Speaker 1>local bulk cruisers, mind you. I'm talking about the big

0:01:08.120 --> 0:01:11.000
<v Speaker 1>Correlian ships. Now she's fast enough for you, old man?

0:01:11.400 --> 0:01:15.000
<v Speaker 1>What's the cargo? Usually I'm the one calling you old man. Yeah,

0:01:15.160 --> 0:01:16.800
<v Speaker 1>that's true. I just wanted to turn that around a

0:01:16.800 --> 0:01:18.800
<v Speaker 1>little bit. I also didn't go full Christopher walk In,

0:01:18.840 --> 0:01:20.920
<v Speaker 1>despite the fact that I love that Saturday Night Live skit.

0:01:21.520 --> 0:01:24.640
<v Speaker 1>So we are talking about the Kessel Run and hyper

0:01:24.720 --> 0:01:27.600
<v Speaker 1>drives in the Star Wars universe and uh, and then

0:01:27.680 --> 0:01:29.679
<v Speaker 1>kind of comparing it to what we would like to

0:01:29.760 --> 0:01:32.880
<v Speaker 1>call real life. Right. And we're doing this, by the way,

0:01:32.920 --> 0:01:36.000
<v Speaker 1>because this is our five first episode and we are

0:01:36.080 --> 0:01:38.080
<v Speaker 1>we we are big fans of the five of first legion.

0:01:38.360 --> 0:01:41.400
<v Speaker 1>That's right, That's right, that's the Uh. This is props

0:01:41.400 --> 0:01:44.240
<v Speaker 1>going out to our Star Wars buddies. So you five

0:01:44.319 --> 0:01:46.679
<v Speaker 1>hundred and first members out there, this one's for you.

0:01:47.280 --> 0:01:49.760
<v Speaker 1>So now, in the original context, we need to talk

0:01:49.760 --> 0:01:53.440
<v Speaker 1>about what the Kessel Run is within the mythology of

0:01:53.520 --> 0:01:56.280
<v Speaker 1>Star Wars, right, and it's not really mentioned in um

0:01:56.360 --> 0:01:59.200
<v Speaker 1>in any of the three original films, right, or even

0:01:59.280 --> 0:02:04.040
<v Speaker 1>the fictional prequels that supposedly exist. No, we should also

0:02:04.040 --> 0:02:08.919
<v Speaker 1>point out, according to everything I've ever read, Lucas considered

0:02:08.960 --> 0:02:12.440
<v Speaker 1>anything that was in the movies cannon correct. Anything outside

0:02:12.440 --> 0:02:16.160
<v Speaker 1>the movies was just extra stuff that may or may

0:02:16.240 --> 0:02:19.440
<v Speaker 1>not line up with what is canon. So there's no

0:02:20.280 --> 0:02:21.560
<v Speaker 1>you know, the stuff that we'll be talking about, a

0:02:21.600 --> 0:02:23.919
<v Speaker 1>lot of this is things that other writers have kind

0:02:23.919 --> 0:02:26.720
<v Speaker 1>of expounded upon in in the novels. Are the comics,

0:02:26.720 --> 0:02:29.520
<v Speaker 1>some of the video games, yeah, some of the cartoons, etcetera.

0:02:29.600 --> 0:02:32.240
<v Speaker 1>And so the stuff that we're talking about this is

0:02:32.280 --> 0:02:35.639
<v Speaker 1>this is mostly people trying to explain away what Lucas

0:02:35.720 --> 0:02:38.800
<v Speaker 1>created in a in a manner that makes kind of sense,

0:02:38.919 --> 0:02:41.120
<v Speaker 1>because a lot of the stuff that you watch in

0:02:41.240 --> 0:02:43.440
<v Speaker 1>Star Wars, if you really think about, you're like, wait

0:02:43.480 --> 0:02:46.640
<v Speaker 1>a minute, it's not science. So the Kessel Run in

0:02:46.680 --> 0:02:51.480
<v Speaker 1>particular is a route in Star Wars, at least this

0:02:51.560 --> 0:02:54.400
<v Speaker 1>is the way it's explained in the Expanded Universe. It's

0:02:54.400 --> 0:02:56.760
<v Speaker 1>it's a smuggling run, right, which is exactly what you know.

0:02:56.760 --> 0:02:59.080
<v Speaker 1>Han Solo is a smuggler, and so this is a

0:02:59.080 --> 0:03:02.960
<v Speaker 1>particular route through space that smugglers would take. And uh.

0:03:03.000 --> 0:03:06.640
<v Speaker 1>And one of the big complaints or criticisms of this

0:03:06.720 --> 0:03:10.240
<v Speaker 1>particular section of dialogue is that Han Solo talks about

0:03:10.320 --> 0:03:13.600
<v Speaker 1>doing a Kessel Run in less than twelve par sex,

0:03:13.639 --> 0:03:17.560
<v Speaker 1>which seems to suggest that he thinks par sex is

0:03:17.600 --> 0:03:20.639
<v Speaker 1>a measure of time, right, and it's not, and it's

0:03:20.760 --> 0:03:22.800
<v Speaker 1>it's certainly not. You know, you know, I think that

0:03:22.880 --> 0:03:25.800
<v Speaker 1>my my strongest um explanation of this is just that

0:03:25.880 --> 0:03:28.840
<v Speaker 1>Han Solo was just saying words. He was just talking

0:03:28.840 --> 0:03:31.720
<v Speaker 1>and trying to sound impressive. My my explanation is Lucas

0:03:31.760 --> 0:03:35.160
<v Speaker 1>thought that parsex sounded futuristic and that it sounds like

0:03:35.200 --> 0:03:38.800
<v Speaker 1>a measurement of time. That was mine, which puts the

0:03:38.880 --> 0:03:41.560
<v Speaker 1>onus on the writer and not the character. But hey,

0:03:41.920 --> 0:03:44.160
<v Speaker 1>you know, I'm a writer. That's kind of how I think.

0:03:44.240 --> 0:03:46.320
<v Speaker 1>Like sometimes I make mistakes too. I'm just saying that

0:03:46.320 --> 0:03:48.000
<v Speaker 1>if you're going to excuse the character saying and I

0:03:48.040 --> 0:03:50.120
<v Speaker 1>think that that is not a poor right if you

0:03:50.120 --> 0:03:52.480
<v Speaker 1>want to be an apologist. Sure, so, So what a

0:03:52.640 --> 0:03:55.840
<v Speaker 1>what a par sec actually is? It is a unit

0:03:55.920 --> 0:04:00.160
<v Speaker 1>of distance and technically based upon UH the uh the

0:04:00.240 --> 0:04:05.320
<v Speaker 1>sun and earth and and and a second of arc. Uh.

0:04:05.640 --> 0:04:10.440
<v Speaker 1>It involves some pretty complex UH concepts that are not

0:04:10.520 --> 0:04:13.320
<v Speaker 1>that complex, but they're difficult to explain an audio format.

0:04:13.440 --> 0:04:16.960
<v Speaker 1>But ultimately it translates to about three point to six

0:04:17.040 --> 0:04:19.440
<v Speaker 1>light years, right, and and it's specifically, by the way,

0:04:19.520 --> 0:04:22.719
<v Speaker 1>tied to to the distance of the Sun from the

0:04:22.760 --> 0:04:25.760
<v Speaker 1>Earth and another object and another object that makes up

0:04:25.800 --> 0:04:29.440
<v Speaker 1>one sec. Yeah, and so you know, forgiving the fact

0:04:29.520 --> 0:04:32.160
<v Speaker 1>that we're talking about a galaxy far far away, and

0:04:32.200 --> 0:04:35.479
<v Speaker 1>that perhaps, as a phil plate of that astronomer pointed out,

0:04:36.520 --> 0:04:39.800
<v Speaker 1>that might not be the most valid measurement. Why would

0:04:39.800 --> 0:04:42.440
<v Speaker 1>another why would people in another galaxy use a unit

0:04:42.480 --> 0:04:45.640
<v Speaker 1>of measurement that's dependent upon the Earth's position relative to

0:04:45.720 --> 0:04:49.200
<v Speaker 1>another object and the Sun. That makes no sense at all.

0:04:49.400 --> 0:04:51.719
<v Speaker 1>But anyway, so it's it's equivalent to about three point

0:04:51.760 --> 0:04:54.160
<v Speaker 1>to six light years, And of course that just makes

0:04:54.160 --> 0:04:56.279
<v Speaker 1>things even more confusing for people who don't know what

0:04:56.320 --> 0:04:58.000
<v Speaker 1>a light year is, and they think light year is

0:04:58.040 --> 0:05:01.720
<v Speaker 1>also a measurement of time. It's not. But at any rate,

0:05:02.279 --> 0:05:05.760
<v Speaker 1>the description Han Solo makes is very confusing if you

0:05:05.800 --> 0:05:08.320
<v Speaker 1>think about parsex being a distance, like, how can you

0:05:08.360 --> 0:05:12.080
<v Speaker 1>take a route and say that your ship made it

0:05:12.080 --> 0:05:15.839
<v Speaker 1>in less than twelve units of distance for that route

0:05:16.080 --> 0:05:20.240
<v Speaker 1>and make that the a measurement of its speed. So

0:05:20.520 --> 0:05:24.120
<v Speaker 1>here's how we're gonna try and explain this well. And

0:05:24.160 --> 0:05:27.880
<v Speaker 1>also I should mention uh in the novelization of a

0:05:27.920 --> 0:05:31.160
<v Speaker 1>new hope. Han Solo does not say Parsex recond that

0:05:31.200 --> 0:05:35.800
<v Speaker 1>real quick. He said standard time units twelve less than

0:05:35.839 --> 0:05:39.320
<v Speaker 1>twelve standard time units. I have no idea how long

0:05:39.320 --> 0:05:42.279
<v Speaker 1>the standard time unit is, but that doesn't really matter,

0:05:42.400 --> 0:05:45.839
<v Speaker 1>I guess. But anyway, so Kessel run, you've got this route.

0:05:46.080 --> 0:05:50.400
<v Speaker 1>It's usually if you are taking the quote unquote safe approach,

0:05:50.800 --> 0:05:54.560
<v Speaker 1>eighteen par sex long, which is about fifty nine light years. Yeah.

0:05:54.600 --> 0:05:57.520
<v Speaker 1>So the reason why it's that long is because the

0:05:57.600 --> 0:06:00.480
<v Speaker 1>route takes you through an area of space that has

0:06:00.960 --> 0:06:04.080
<v Speaker 1>black holes in it. It's called the mall. And the

0:06:04.200 --> 0:06:08.800
<v Speaker 1>mall in a w would destroy a ship if you

0:06:08.880 --> 0:06:10.320
<v Speaker 1>got too close to it. It's you know, it's a

0:06:10.320 --> 0:06:13.120
<v Speaker 1>black holes. There are bad times for ships, right you know?

0:06:13.480 --> 0:06:16.200
<v Speaker 1>You know you do? Have you heard what the term

0:06:16.360 --> 0:06:19.200
<v Speaker 1>is for something that gets pulled through a black hole?

0:06:19.600 --> 0:06:22.240
<v Speaker 1>The term of what is happening to it? Spaganifications my

0:06:22.400 --> 0:06:25.799
<v Speaker 1>favorite thing in the world. Yes, because it gets pulled

0:06:25.800 --> 0:06:29.240
<v Speaker 1>into these long, thin strands as it's being uh infinitely

0:06:29.279 --> 0:06:33.600
<v Speaker 1>thin strands hypothetically being pulled towards this center of intense

0:06:33.800 --> 0:06:38.440
<v Speaker 1>density or intensity as I like to call it. Anyway,

0:06:38.520 --> 0:06:40.720
<v Speaker 1>So usually this route would be eighteen par sex long.

0:06:40.800 --> 0:06:45.520
<v Speaker 1>But if one were to be a little daring or

0:06:45.640 --> 0:06:51.640
<v Speaker 1>perhaps insane, completely crazy, one might be able to plot

0:06:51.680 --> 0:06:54.960
<v Speaker 1>a route that goes closer to the black holes, you

0:06:55.040 --> 0:06:57.200
<v Speaker 1>kind of skirt around it. And you know, Han Solo,

0:06:57.279 --> 0:06:59.760
<v Speaker 1>being the guy that he is, he's he says, you know,

0:07:00.160 --> 0:07:02.880
<v Speaker 1>time is money, or distance is money, or money is

0:07:02.920 --> 0:07:07.080
<v Speaker 1>money or something I don't know. Anyway, he wanted to

0:07:07.120 --> 0:07:09.200
<v Speaker 1>be able to take a more direct route, which would

0:07:09.240 --> 0:07:14.040
<v Speaker 1>shave off about six or so parsecs from this eighteen

0:07:14.120 --> 0:07:17.120
<v Speaker 1>parsec long route, and that means that you know, he's

0:07:17.160 --> 0:07:20.240
<v Speaker 1>he's essentially instead of going like a curved line, he's

0:07:20.240 --> 0:07:23.760
<v Speaker 1>making a straight line. Not quite like that dramatic, but

0:07:23.840 --> 0:07:27.400
<v Speaker 1>close to it. So in other words, he's taking a

0:07:27.520 --> 0:07:30.280
<v Speaker 1>route and making it more efficient, but it is much

0:07:30.320 --> 0:07:36.760
<v Speaker 1>more dangerous. There's no direct relationship between the Millennium Falcon's

0:07:36.960 --> 0:07:41.440
<v Speaker 1>speed and this route immediately, but one could argue, and

0:07:41.520 --> 0:07:45.080
<v Speaker 1>one has. In fact, Kyle Hill of Wired wrote a

0:07:45.200 --> 0:07:48.680
<v Speaker 1>great article how the Star Wars Kessel Run turns Hans

0:07:48.760 --> 0:07:52.120
<v Speaker 1>Solo into a time traveler. Fantastic article. It's really well

0:07:52.160 --> 0:07:55.560
<v Speaker 1>link it. It's great. Yeah, it's entertaining and uh and

0:07:55.600 --> 0:07:59.840
<v Speaker 1>also it starts to build in some chronological problems in

0:07:59.880 --> 0:08:02.440
<v Speaker 1>the Star Wars universe, but we'll get into those. But anyway,

0:08:02.480 --> 0:08:07.360
<v Speaker 1>he points out that that you could end up thinking, oh, well,

0:08:07.360 --> 0:08:10.119
<v Speaker 1>the Millennium Falcon has to be the fast ship because

0:08:10.160 --> 0:08:12.760
<v Speaker 1>it has to be able to escape that pull of

0:08:12.760 --> 0:08:15.960
<v Speaker 1>the black holes. So therefore that's what tells you that

0:08:15.960 --> 0:08:18.200
<v Speaker 1>it's fast. Is not only that heating only is the

0:08:18.240 --> 0:08:22.160
<v Speaker 1>pilot capable of making a more efficient route to go

0:08:22.240 --> 0:08:24.200
<v Speaker 1>through the Kessel Run, but it's also in the ship

0:08:24.280 --> 0:08:27.160
<v Speaker 1>fast enough to a black roles, right right? Yeah, Well,

0:08:27.200 --> 0:08:30.240
<v Speaker 1>according to a Wikipedia um, which is one of the

0:08:30.240 --> 0:08:32.440
<v Speaker 1>best wikis ever, I just said that on the air

0:08:32.440 --> 0:08:35.600
<v Speaker 1>it was wonderful. Um. In the commentary for Star Wars

0:08:35.640 --> 0:08:38.840
<v Speaker 1>episode for a New Hope DVD, George Lucas said that

0:08:38.920 --> 0:08:42.920
<v Speaker 1>the Millennium Falcons navigational computers were highly advanced and that

0:08:42.920 --> 0:08:46.040
<v Speaker 1>that was why the parsic thing works out the way

0:08:46.040 --> 0:08:49.120
<v Speaker 1>that it does. Yeah. Yeah, so essentially then you just

0:08:49.200 --> 0:08:52.360
<v Speaker 1>make Han Solo a guyo flips switches, a really good

0:08:52.520 --> 0:08:55.800
<v Speaker 1>flip switcher. There's also a great thing that was at

0:08:55.800 --> 0:08:59.120
<v Speaker 1>the Smithsonian, one of the Star Wars exhibit where uh,

0:08:59.400 --> 0:09:01.839
<v Speaker 1>Harrison's It was actually talking about the first time they

0:09:01.880 --> 0:09:05.560
<v Speaker 1>shot uh seen in the cockpit of the Millennium Falcon

0:09:05.920 --> 0:09:08.000
<v Speaker 1>and George Lucas gave him the direction of your flying

0:09:08.040 --> 0:09:10.719
<v Speaker 1>the ship and he says, Okay, how do I do that?

0:09:11.480 --> 0:09:13.600
<v Speaker 1>Because there are just all these dials and switches and

0:09:13.760 --> 0:09:17.040
<v Speaker 1>they didn't There was no rhyme or reason to its

0:09:17.120 --> 0:09:20.840
<v Speaker 1>was like, I don't know the buttons pull that lever

0:09:21.640 --> 0:09:24.679
<v Speaker 1>pushed the button frank, So anyway you might wonder, well,

0:09:24.720 --> 0:09:27.240
<v Speaker 1>why what's the big deal of the Kessel run? Anyway

0:09:27.360 --> 0:09:30.360
<v Speaker 1>was what was the significance? Like it's a smuggling route,

0:09:30.360 --> 0:09:33.240
<v Speaker 1>but it's a smuggling route for what? And within the

0:09:33.320 --> 0:09:37.920
<v Speaker 1>lore again this again nothing films expanded universe, so not Cannon.

0:09:39.040 --> 0:09:44.280
<v Speaker 1>Kessel was a planet that had these mines on it

0:09:44.320 --> 0:09:48.359
<v Speaker 1>for something called glitter stem spice, which was a substance

0:09:48.400 --> 0:09:53.480
<v Speaker 1>created by spice spiders, and it's a photoactive substance, so

0:09:53.520 --> 0:09:55.439
<v Speaker 1>it activates when light hits it, So it had to

0:09:55.480 --> 0:09:58.800
<v Speaker 1>be mined in complete darkness. It could not be exposed

0:09:58.840 --> 0:10:01.840
<v Speaker 1>to light in anywhere or else it lose its potency.

0:10:01.920 --> 0:10:07.160
<v Speaker 1>And the spice was essentially a drug. Uh As Cheery

0:10:07.160 --> 0:10:08.480
<v Speaker 1>as that is, I do want to point out that

0:10:08.520 --> 0:10:12.079
<v Speaker 1>I'm pretty sure the word castle comes from during World

0:10:12.080 --> 0:10:14.720
<v Speaker 1>War Two. You know, the Germans got themselves really good

0:10:14.720 --> 0:10:16.920
<v Speaker 1>and surrounded by a group of Russians and uh and

0:10:17.000 --> 0:10:19.800
<v Speaker 1>some of their compatriots were trying to get supplies and

0:10:19.800 --> 0:10:23.600
<v Speaker 1>aid to uh their their surrounding colleagues colleagues. Yeah sure,

0:10:23.640 --> 0:10:26.960
<v Speaker 1>and this failed completely. But but the word kessel means

0:10:26.960 --> 0:10:32.240
<v Speaker 1>that like pocket in Germany, thint cattle, yeah, dosson thrish

0:10:32.280 --> 0:10:35.680
<v Speaker 1>dish uh So the Gli stump spice stuff. What it

0:10:35.720 --> 0:10:38.160
<v Speaker 1>was supposed to do within the realm of Star Wars

0:10:38.440 --> 0:10:41.640
<v Speaker 1>is boost your mental capacity and even give you perhaps

0:10:41.720 --> 0:10:44.319
<v Speaker 1>telepathic powers for a short amount of time. It was

0:10:44.360 --> 0:10:48.040
<v Speaker 1>also incredibly addictive. This is this makes Hanselo an even

0:10:48.120 --> 0:10:50.400
<v Speaker 1>darker character in a way because he's smuggling. Yeah, he

0:10:50.480 --> 0:10:54.920
<v Speaker 1>runs drugs. Um so, yeah, that's kind of grim. But

0:10:55.480 --> 0:10:58.400
<v Speaker 1>in the during the Galactic Republic, which is the period

0:10:58.440 --> 0:11:01.920
<v Speaker 1>that proceeds a New Hope, that's back when there was

0:11:02.000 --> 0:11:05.680
<v Speaker 1>a the Old Republic was around. It was being used medically.

0:11:06.280 --> 0:11:09.400
<v Speaker 1>But then the republic fails and then the black market

0:11:09.480 --> 0:11:12.360
<v Speaker 1>takes over. Smugglers start selling this. I guess more like

0:11:12.440 --> 0:11:16.080
<v Speaker 1>recreational drugs as opposed to medical things, and the Empire

0:11:16.120 --> 0:11:19.200
<v Speaker 1>outlaws it. And so that's why it's important to be

0:11:19.240 --> 0:11:25.120
<v Speaker 1>able to avoid imperial entanglements, as Obi Wan says in

0:11:25.200 --> 0:11:29.320
<v Speaker 1>a New Hope. So that's why it's important that there's

0:11:29.360 --> 0:11:34.000
<v Speaker 1>the explanation of shaving off some of the distance that

0:11:34.040 --> 0:11:36.200
<v Speaker 1>it would normally take you to to travel in order

0:11:36.200 --> 0:11:38.559
<v Speaker 1>to get there, and also the fact that the Falcon

0:11:38.640 --> 0:11:41.720
<v Speaker 1>would have to be a little faster than most ships. Now,

0:11:41.920 --> 0:11:44.320
<v Speaker 1>all of that is kind of cool. I can. I

0:11:44.360 --> 0:11:47.040
<v Speaker 1>can kind of handle most of that, even though I

0:11:47.080 --> 0:11:49.360
<v Speaker 1>think that the parseec thing is really an apologist. It's

0:11:49.400 --> 0:11:54.719
<v Speaker 1>a redcon or retroactive continuity where you after you've made

0:11:54.720 --> 0:11:56.760
<v Speaker 1>a mistake, you go back and try to justify the

0:11:56.760 --> 0:12:00.120
<v Speaker 1>fact that a mistake is there. Uh, this is the

0:12:00.120 --> 0:12:06.880
<v Speaker 1>way in no way unlimited to Star Wars. It's extraordinarily common. Um, yes, everywhere, Yeah,

0:12:07.040 --> 0:12:10.480
<v Speaker 1>it's yeah. So the other thing that Hans Solo says

0:12:10.600 --> 0:12:13.880
<v Speaker 1>is that can go at point five beyond light speed.

0:12:13.960 --> 0:12:17.960
<v Speaker 1>So I interpret that to mean half again faster than

0:12:17.960 --> 0:12:20.880
<v Speaker 1>the speed of light. I I interpreted it as as

0:12:20.920 --> 0:12:24.120
<v Speaker 1>a as point five percent of light speed. Above light speed.

0:12:24.200 --> 0:12:27.120
<v Speaker 1>But but but your sounds much more impressive. But that

0:12:27.160 --> 0:12:29.800
<v Speaker 1>would be much mind would be much more impressive. Either way,

0:12:29.840 --> 0:12:32.960
<v Speaker 1>you're violating the laws of physics as we understand them.

0:12:33.720 --> 0:12:37.400
<v Speaker 1>Because as we as we understand the speed of light

0:12:37.480 --> 0:12:40.920
<v Speaker 1>through a vacuum is the universal speed limit. Nothing can

0:12:40.960 --> 0:12:44.000
<v Speaker 1>go faster than light through a vacuum physically impossible. Now

0:12:44.040 --> 0:12:48.000
<v Speaker 1>we should also mention light itself does not necessarily travel

0:12:48.040 --> 0:12:51.679
<v Speaker 1>at the same speed through all media. You know, through

0:12:51.679 --> 0:12:54.720
<v Speaker 1>a vacuum, it travels at an incredible clip. It's about

0:12:55.120 --> 0:13:01.040
<v Speaker 1>two d million, seven fifty eight meters per second, or

0:13:01.360 --> 0:13:04.880
<v Speaker 1>around one six thousand, two eighty two miles per second.

0:13:05.679 --> 0:13:08.920
<v Speaker 1>That's through the vacuum of space and solos ship. If

0:13:08.920 --> 0:13:11.360
<v Speaker 1>you assume it could go half again faster than the

0:13:11.360 --> 0:13:14.160
<v Speaker 1>speed of light would have its top speed, it's somewhere

0:13:14.160 --> 0:13:18.240
<v Speaker 1>around four hundred forty nine million, million, six eight thousand

0:13:18.280 --> 0:13:21.920
<v Speaker 1>six or eighty seven per second, or two thousand, four

0:13:22.000 --> 0:13:26.160
<v Speaker 1>hundred twenty four miles per second. That's really fast, And

0:13:26.240 --> 0:13:29.160
<v Speaker 1>of course it is faster than anything we can we

0:13:29.360 --> 0:13:32.040
<v Speaker 1>we know of, besides some theoretical particles that we'll talk

0:13:32.040 --> 0:13:34.839
<v Speaker 1>about in a little bit. That's faster than anything we

0:13:34.960 --> 0:13:38.520
<v Speaker 1>know of can go. That makes it really problematic because

0:13:38.600 --> 0:13:41.199
<v Speaker 1>if we just talk about parsecs and shaving off distance,

0:13:41.640 --> 0:13:44.480
<v Speaker 1>you know, Okay, I can see that we still have

0:13:44.600 --> 0:13:49.000
<v Speaker 1>the problem of a parsec is a really long distance, right, Yeah,

0:13:49.280 --> 0:13:52.679
<v Speaker 1>So how you know, if Han Solo made the kessel run,

0:13:53.559 --> 0:13:56.160
<v Speaker 1>how long would it take him to do it? Assuming

0:13:56.200 --> 0:13:59.199
<v Speaker 1>that he's traveling at around the speed of light? And yeah, yeah,

0:13:59.200 --> 0:14:01.240
<v Speaker 1>I mean if if you're if you nudge right up

0:14:01.280 --> 0:14:03.320
<v Speaker 1>to the speed of light, they would take about thirty

0:14:03.400 --> 0:14:07.199
<v Speaker 1>nine years travel twelve par sex that that would be.

0:14:07.760 --> 0:14:11.080
<v Speaker 1>That would be due to an independent observer though correct

0:14:11.160 --> 0:14:14.079
<v Speaker 1>because special relativity. But we'll talk about that. Yeah, I

0:14:14.120 --> 0:14:15.880
<v Speaker 1>don't want to get into that right now, but special

0:14:15.920 --> 0:14:17.920
<v Speaker 1>relativity will play a part in our second part of

0:14:17.960 --> 0:14:21.200
<v Speaker 1>our conversation because also we should go ahead and say it.

0:14:21.440 --> 0:14:23.720
<v Speaker 1>According to Star Wars, and again this is a retcon

0:14:23.840 --> 0:14:27.760
<v Speaker 1>type thing, all ships have a stasis field stabilizer thing

0:14:27.840 --> 0:14:30.760
<v Speaker 1>that keeps time. It's a universal constant of time amongst

0:14:30.880 --> 0:14:33.920
<v Speaker 1>the Empire, which is really convenient because otherwise Han Solo

0:14:34.000 --> 0:14:36.640
<v Speaker 1>would be older than Yoda right after he had taken

0:14:37.000 --> 0:14:39.040
<v Speaker 1>what I don't know, like like two or three trips

0:14:39.120 --> 0:14:43.000
<v Speaker 1>yea four or five three trips on the Kestle run.

0:14:43.040 --> 0:14:44.680
<v Speaker 1>But it does sound like he's done it multiple times,

0:14:44.720 --> 0:14:47.240
<v Speaker 1>which means that if he's done the Kestle run multiple times,

0:14:47.600 --> 0:14:50.040
<v Speaker 1>that special relativity problem, which again we'll talk about in

0:14:50.040 --> 0:14:53.880
<v Speaker 1>a minute just to Paine. Right. So, so here's here's

0:14:53.920 --> 0:14:57.880
<v Speaker 1>the thing. The stasis is supposed to keep everything constant. Uh.

0:14:58.360 --> 0:15:01.280
<v Speaker 1>Time is a tricky thing, but it doesn't matter. It's

0:15:01.320 --> 0:15:05.480
<v Speaker 1>not just if you're traveling nearer or at or above

0:15:05.600 --> 0:15:07.080
<v Speaker 1>the speed of light where you have to take it

0:15:07.160 --> 0:15:11.400
<v Speaker 1>into account. Every single planet that's in the entire galaxy

0:15:11.440 --> 0:15:14.600
<v Speaker 1>of Star Wars has time pass at a different rate

0:15:15.440 --> 0:15:19.520
<v Speaker 1>according to any according to physics. Yeah, and again it's relative.

0:15:19.800 --> 0:15:23.200
<v Speaker 1>So if Lauren's on one planet and I'm on another planet,

0:15:23.600 --> 0:15:25.440
<v Speaker 1>each of us are going to feel as if time

0:15:25.560 --> 0:15:29.680
<v Speaker 1>is passing at the same speed individually, like a second

0:15:29.720 --> 0:15:31.520
<v Speaker 1>will feel like a second to me, a second will

0:15:31.560 --> 0:15:34.280
<v Speaker 1>feel like a second to Lauren. However, depending upon the

0:15:34.800 --> 0:15:37.640
<v Speaker 1>planet's mass and the speed at which it travels through space,

0:15:38.040 --> 0:15:40.800
<v Speaker 1>the actual passage of time is going to be different

0:15:41.280 --> 0:15:44.080
<v Speaker 1>relative to each other. So if we match our watches up,

0:15:44.120 --> 0:15:47.560
<v Speaker 1>we'll see that they're not keeping exact synchronized time. And

0:15:47.640 --> 0:15:50.680
<v Speaker 1>again more on that and just a bit. I have

0:15:50.800 --> 0:15:53.360
<v Speaker 1>to I have to preface it because it's it makes

0:15:53.480 --> 0:15:58.200
<v Speaker 1>my head swim, all right. So the other element in

0:15:58.320 --> 0:16:01.800
<v Speaker 1>this Star Wars universe is the idea of hyper space

0:16:02.120 --> 0:16:05.200
<v Speaker 1>and hyperdrive. And so this is when, and if you've

0:16:05.200 --> 0:16:07.320
<v Speaker 1>watched the Star Wars movies, you know, they engage the

0:16:07.400 --> 0:16:10.960
<v Speaker 1>hyperdrive and then suddenly all the stars start streaking towards

0:16:11.000 --> 0:16:14.840
<v Speaker 1>them in this beautiful display. And from from the outside

0:16:15.160 --> 0:16:17.400
<v Speaker 1>it looks like the ship just suddenly gets an enormous

0:16:17.480 --> 0:16:21.440
<v Speaker 1>speed boost, and yet no one is is slammed back

0:16:21.520 --> 0:16:24.520
<v Speaker 1>against the back of the the Millennium falcon like and

0:16:24.960 --> 0:16:28.680
<v Speaker 1>ejected into space because of the massive acceleration. That would

0:16:28.680 --> 0:16:30.800
<v Speaker 1>be a pretty pretty lame trip. It would be really

0:16:30.920 --> 0:16:33.040
<v Speaker 1>would be funny to see, like the the activation of

0:16:33.080 --> 0:16:34.680
<v Speaker 1>the first hyper drive and then you just see a

0:16:34.720 --> 0:16:37.240
<v Speaker 1>bunch of a leads just floating free in space like well,

0:16:37.360 --> 0:16:39.880
<v Speaker 1>that was a bad idea, um because that kind of

0:16:39.960 --> 0:16:42.400
<v Speaker 1>this kind of happens in Fire Escape. That's for for

0:16:42.760 --> 0:16:45.120
<v Speaker 1>you kids out there. We need to make Jonathan watch that. Anyway,

0:16:45.160 --> 0:16:47.920
<v Speaker 1>I've never watched it, so so it's it's not very

0:16:48.000 --> 0:16:51.040
<v Speaker 1>well defined hyperspace, and in the Star Wars universe, even

0:16:51.120 --> 0:16:54.240
<v Speaker 1>in the expanded universe a right, right, it's hyperspace is

0:16:54.280 --> 0:16:57.280
<v Speaker 1>kind of placed in contrast to real space. Yeah, you know,

0:16:57.400 --> 0:16:59.200
<v Speaker 1>real space being of course what we're kind of moving

0:16:59.240 --> 0:17:02.560
<v Speaker 1>around and the under under normal speed constraints are moving

0:17:02.600 --> 0:17:05.040
<v Speaker 1>around it. And then and then yeah, apparently these these

0:17:05.280 --> 0:17:09.000
<v Speaker 1>hypermatter reactor drives with hypermatter implosion cores. I mean, it

0:17:09.080 --> 0:17:10.760
<v Speaker 1>sounds a little bit like a like a wormhole or

0:17:10.800 --> 0:17:13.520
<v Speaker 1>a tests or act something like that. Like, again, it's

0:17:13.560 --> 0:17:17.040
<v Speaker 1>not very well explained. So some of there's like it

0:17:17.040 --> 0:17:19.040
<v Speaker 1>could be a parallel universe where you open up a

0:17:19.119 --> 0:17:21.920
<v Speaker 1>gate and you travel into a new universe, and then

0:17:21.960 --> 0:17:24.359
<v Speaker 1>you open up a second gate and you re emerge

0:17:24.400 --> 0:17:27.240
<v Speaker 1>into quote unquote our universe the start, or at least

0:17:27.280 --> 0:17:31.159
<v Speaker 1>the Star Wars universe real space, but you are you know,

0:17:31.240 --> 0:17:33.199
<v Speaker 1>in a different point of real space than you were

0:17:33.240 --> 0:17:36.040
<v Speaker 1>when you started. Um Or it could be an extra

0:17:36.160 --> 0:17:39.600
<v Speaker 1>dimension in space, which is kind of like warp drive

0:17:39.720 --> 0:17:42.639
<v Speaker 1>where you're warping space around you. It could be an

0:17:42.680 --> 0:17:45.760
<v Speaker 1>alternate mode of physical existence, which I said is kind

0:17:45.760 --> 0:17:47.920
<v Speaker 1>of like an astral plane for those of you who

0:17:48.000 --> 0:17:51.440
<v Speaker 1>play fantasy games where you can travel to that um

0:17:51.800 --> 0:17:54.080
<v Speaker 1>or it could just be traveling faster than the speed

0:17:54.160 --> 0:17:57.520
<v Speaker 1>of light, and all of that is difficult to to

0:17:57.640 --> 0:18:01.240
<v Speaker 1>get your head around. Again, none of that was definitively

0:18:01.440 --> 0:18:04.359
<v Speaker 1>set down in the movies as this is how hyper

0:18:04.480 --> 0:18:07.520
<v Speaker 1>drive works or hyperspace. So we have a lot of

0:18:07.600 --> 0:18:10.600
<v Speaker 1>different things to choose from and uh, and it seems

0:18:10.640 --> 0:18:13.040
<v Speaker 1>to me that a lot of the people who write

0:18:13.280 --> 0:18:15.760
<v Speaker 1>in the Star Wars universe or who have tried to

0:18:15.920 --> 0:18:19.520
<v Speaker 1>explain the Star Wars universe have kind of fudged around

0:18:19.680 --> 0:18:23.360
<v Speaker 1>with this a lot. No one has really come out

0:18:23.440 --> 0:18:27.040
<v Speaker 1>with what is the definitive answer as to what this is? Right? Sure,

0:18:27.080 --> 0:18:30.119
<v Speaker 1>and and this I used this example about about once

0:18:30.200 --> 0:18:32.000
<v Speaker 1>a week with Jonathan, but it always reminds me of

0:18:32.080 --> 0:18:34.280
<v Speaker 1>this one terrific interview that Rick Burman did about a

0:18:34.520 --> 0:18:40.040
<v Speaker 1>Star Trek, specifically the UH Eisenberg uncertainty compensators and the transporters,

0:18:40.080 --> 0:18:41.440
<v Speaker 1>and someone was like, well, how did those work? And

0:18:41.480 --> 0:18:43.600
<v Speaker 1>he was like, very well, thank you, next question. Yeah,

0:18:44.000 --> 0:18:47.479
<v Speaker 1>whereas you know, the holidack works very poorly, or at

0:18:47.520 --> 0:18:50.800
<v Speaker 1>least it breaks down once a year. But again within

0:18:50.920 --> 0:18:54.440
<v Speaker 1>the lore of Star Wars. Hyperspace itself is first discovered

0:18:54.480 --> 0:18:57.720
<v Speaker 1>by a race called the Raccotta, and they create ricata

0:18:57.840 --> 0:19:01.119
<v Speaker 1>like the cheese. No, it's our a k A t A. Okay,

0:19:01.440 --> 0:19:04.399
<v Speaker 1>just checking. You're gonna remember that Star Wars often the

0:19:04.480 --> 0:19:08.800
<v Speaker 1>pronunciations are exactly the same as very silly stuff here

0:19:08.840 --> 0:19:12.600
<v Speaker 1>on Earth. Funny about that, um. But anyway, they they

0:19:13.000 --> 0:19:17.760
<v Speaker 1>created force powered drives, so they were tapping into the

0:19:17.800 --> 0:19:21.560
<v Speaker 1>power of the Force to travel through space at incredible speeds.

0:19:21.840 --> 0:19:24.400
<v Speaker 1>And there there, I have no problem because the force

0:19:24.560 --> 0:19:27.320
<v Speaker 1>is magic, and and magic means you do not have

0:19:27.520 --> 0:19:31.080
<v Speaker 1>to explain how something works technologically, physics, it's right out

0:19:31.119 --> 0:19:33.800
<v Speaker 1>the windows, right, Yeah, you know it's a fairy tale.

0:19:33.960 --> 0:19:36.720
<v Speaker 1>You don't question the physics of a fairy tale, you know.

0:19:36.960 --> 0:19:40.080
<v Speaker 1>I mean if you sit there and say, well, wouldn't

0:19:40.680 --> 0:19:44.320
<v Speaker 1>prints climbing Rapunzel's hair, scalp her and leave her screaming

0:19:44.440 --> 0:19:47.360
<v Speaker 1>in pain, that doesn't make the fairy tale very much fun.

0:19:48.600 --> 0:19:51.720
<v Speaker 1>Uh would have been a very short movie. Tangled would

0:19:51.720 --> 0:19:54.480
<v Speaker 1>have been very grim and not in a fairy tale

0:19:54.520 --> 0:19:56.919
<v Speaker 1>kind of Okay, anyway, I'm getting off track. But they

0:19:57.280 --> 0:19:59.840
<v Speaker 1>used the force, and I thought, oh, well, if it's

0:20:00.080 --> 0:20:05.160
<v Speaker 1>thing that's force space then except that then within again

0:20:05.200 --> 0:20:09.200
<v Speaker 1>the expanded lore. The Karelians Karelias, one of the planets

0:20:09.480 --> 0:20:15.200
<v Speaker 1>in the Star Wars universe, and the Euros both found

0:20:15.680 --> 0:20:19.840
<v Speaker 1>these starship drives and using reverse engineering, determined how they

0:20:19.920 --> 0:20:24.119
<v Speaker 1>worked and created technological versions of these force driven drives.

0:20:24.160 --> 0:20:27.719
<v Speaker 1>So they use technology to replicate what the force did.

0:20:28.680 --> 0:20:32.439
<v Speaker 1>And now now we have a technological explanation for how

0:20:32.600 --> 0:20:35.720
<v Speaker 1>hyperspace works. Except there's no actual explanation there. It's just

0:20:35.800 --> 0:20:38.960
<v Speaker 1>that it is technological. Now this is what drives me

0:20:39.040 --> 0:20:41.679
<v Speaker 1>crazy because then I'm like, okay, wait no, So if

0:20:41.680 --> 0:20:43.399
<v Speaker 1>there is a technical way to make it happen, how

0:20:43.480 --> 0:20:47.120
<v Speaker 1>does it work? Um? And and really we have more

0:20:47.200 --> 0:20:51.719
<v Speaker 1>about the process than anything else. So uh. In the movies,

0:20:51.920 --> 0:20:53.959
<v Speaker 1>when they were going to make a jump to hyperspace,

0:20:54.440 --> 0:20:58.760
<v Speaker 1>they would activate the ship's navigational computer, which would calculate

0:20:58.800 --> 0:21:01.959
<v Speaker 1>whatever the route needed to And this was important because,

0:21:02.760 --> 0:21:06.000
<v Speaker 1>as Han Solo explains to Luke, who is an impatient

0:21:06.040 --> 0:21:09.320
<v Speaker 1>little brat in a New Hope, he explains, like, you

0:21:09.440 --> 0:21:11.879
<v Speaker 1>can't hurry this stuff because if you do, you pass

0:21:11.960 --> 0:21:14.520
<v Speaker 1>too close to a star or a planet, it pulls

0:21:14.520 --> 0:21:17.199
<v Speaker 1>you out of hyperspace and you could die. Yeah. Yeah. Now,

0:21:17.359 --> 0:21:21.040
<v Speaker 1>now this to me creates another problem because if hyperspace

0:21:21.200 --> 0:21:24.359
<v Speaker 1>is in fact a parallel universe, why do things that

0:21:24.520 --> 0:21:28.280
<v Speaker 1>exist in our meat space affect you when you're in

0:21:28.280 --> 0:21:30.680
<v Speaker 1>the parallel universe, unless, of course they also have a

0:21:30.760 --> 0:21:34.200
<v Speaker 1>presence in that parallel universe. I I do, I don't know.

0:21:34.280 --> 0:21:36.520
<v Speaker 1>And it sounds much more like a like a like

0:21:36.600 --> 0:21:40.800
<v Speaker 1>a wormhole, like like you're somehow jumping from from point

0:21:40.880 --> 0:21:44.400
<v Speaker 1>to point along kind of a like like an conveyor

0:21:44.480 --> 0:21:46.520
<v Speaker 1>belt sort of thing, which is another concept that we

0:21:46.560 --> 0:21:48.880
<v Speaker 1>can talk about in a minute. So you're you're thinking

0:21:48.920 --> 0:21:52.480
<v Speaker 1>more along the lines of this parallel universe has has

0:21:53.080 --> 0:21:58.840
<v Speaker 1>certain anchor points to real space that it does pass through,

0:21:59.080 --> 0:22:01.399
<v Speaker 1>even if it's not a one to one ratio. Is

0:22:01.440 --> 0:22:03.600
<v Speaker 1>that kind of what you're talking about or yeah, or

0:22:03.680 --> 0:22:05.240
<v Speaker 1>kind of like I don't know, like like there's just

0:22:05.359 --> 0:22:08.080
<v Speaker 1>certain sections of space that you can go much faster

0:22:08.440 --> 0:22:12.320
<v Speaker 1>through and and unfortunately, you know sometimes as some gets

0:22:12.359 --> 0:22:14.280
<v Speaker 1>in the way. So you're talking about like the auto

0:22:14.359 --> 0:22:17.560
<v Speaker 1>bawn of space. Yeah, and that's another thing that I

0:22:17.640 --> 0:22:21.480
<v Speaker 1>was reading on Wikipedia, was was saying, was saying that

0:22:21.600 --> 0:22:24.560
<v Speaker 1>there maybe about eight of these, according to the Star

0:22:24.640 --> 0:22:27.960
<v Speaker 1>Wars universe kicking around and that are super safe roots,

0:22:28.000 --> 0:22:30.080
<v Speaker 1>and then there's some that are pretty shady and wind

0:22:30.160 --> 0:22:32.680
<v Speaker 1>up getting me stuck in an asteroid. Wow. Okay, well,

0:22:32.760 --> 0:22:34.399
<v Speaker 1>at any rate, it does make me sit there and

0:22:34.520 --> 0:22:38.480
<v Speaker 1>think this parallel universe explanation is is harder to get

0:22:38.520 --> 0:22:41.399
<v Speaker 1>my mind wrapped around if things in real space can

0:22:41.480 --> 0:22:46.360
<v Speaker 1>affect you're traveling through the parallel universe, unless, of course, uh,

0:22:46.800 --> 0:22:49.960
<v Speaker 1>it's just talking about how where your output is going

0:22:50.040 --> 0:22:51.800
<v Speaker 1>to be, like where your stopping point is going to be,

0:22:52.040 --> 0:22:55.040
<v Speaker 1>then obviously would be important if if it um maybe

0:22:55.080 --> 0:22:57.360
<v Speaker 1>it has to calculate all right, well, during the process,

0:22:57.720 --> 0:22:59.520
<v Speaker 1>like right now, if we were to leave, if we

0:22:59.560 --> 0:23:02.320
<v Speaker 1>were to instantaneously jumped to this endpoint right now, we'd

0:23:02.359 --> 0:23:04.440
<v Speaker 1>be fine. But by the time we actually get there,

0:23:04.440 --> 0:23:06.200
<v Speaker 1>there's gonna be a planet in the way because of

0:23:06.240 --> 0:23:08.600
<v Speaker 1>the rotation of the planets. Then I'm like, okay, all right,

0:23:08.640 --> 0:23:11.000
<v Speaker 1>I got it. Now that makes sense. It was to me.

0:23:11.080 --> 0:23:13.000
<v Speaker 1>It was the stuff that was on the pathway that

0:23:13.040 --> 0:23:17.200
<v Speaker 1>made no sense. But anyway, the hyper drive would create

0:23:17.320 --> 0:23:20.879
<v Speaker 1>ripples in the time space matrix using a fusion reaction

0:23:21.000 --> 0:23:24.560
<v Speaker 1>and gamma radiation and then the ripples would propel the

0:23:24.640 --> 0:23:27.720
<v Speaker 1>ship into hyperspace. And none of that makes any sense,

0:23:29.119 --> 0:23:31.280
<v Speaker 1>but then again, it sounds really impressive if you're just

0:23:31.400 --> 0:23:33.399
<v Speaker 1>not thinking at all. If if you're just if Han

0:23:33.480 --> 0:23:36.200
<v Speaker 1>Solo were reading that, I would be like, yeah, total, yeah,

0:23:36.280 --> 0:23:37.919
<v Speaker 1>well let me come on. He was kind of dreamy,

0:23:39.400 --> 0:23:42.240
<v Speaker 1>just we just bought anything, he said, uh yeah. And

0:23:42.400 --> 0:23:44.719
<v Speaker 1>and this also reminds me of warp drive as well,

0:23:44.760 --> 0:23:47.760
<v Speaker 1>where you're you're warping the time space. In this case

0:23:47.800 --> 0:23:50.120
<v Speaker 1>it's the time space matrix and in star check could

0:23:50.119 --> 0:23:52.960
<v Speaker 1>be the space time continuum. But either way, it's the

0:23:53.080 --> 0:23:57.320
<v Speaker 1>idea of warping the dimensions themselves in order to propel

0:23:57.480 --> 0:24:01.760
<v Speaker 1>you across vast distances that incredible speeds. And uh and

0:24:01.920 --> 0:24:05.399
<v Speaker 1>so that's kind of the breakdown of how it worked

0:24:05.480 --> 0:24:08.600
<v Speaker 1>within the lore of Star Wars. All Right, guys, I'm

0:24:08.600 --> 0:24:11.440
<v Speaker 1>gonna interrupt this classic episode for just a moment so

0:24:11.520 --> 0:24:21.919
<v Speaker 1>that we can take a quick break to thank our sponsors. Alright,

0:24:22.000 --> 0:24:24.840
<v Speaker 1>so let's get back to hyperspace. So we mentioned in

0:24:24.920 --> 0:24:27.080
<v Speaker 1>the first half nothing can go faster than the speed

0:24:27.119 --> 0:24:30.080
<v Speaker 1>of light, this universal speed. Look, yeah, it's it's smart

0:24:30.119 --> 0:24:32.840
<v Speaker 1>people such as Einstein have talked a lot about that, right,

0:24:32.960 --> 0:24:38.240
<v Speaker 1>and that that speed and time themselves actually have a relationship.

0:24:38.760 --> 0:24:42.679
<v Speaker 1>And so this gets us into special relativity. There are

0:24:42.680 --> 0:24:44.960
<v Speaker 1>a lot of different aspects of special relativity, but the

0:24:45.000 --> 0:24:47.200
<v Speaker 1>one that interests me the most in this discussion is

0:24:47.240 --> 0:24:52.840
<v Speaker 1>the fact that as objects move faster, time dilates on

0:24:53.000 --> 0:24:56.399
<v Speaker 1>that object relative to a stationary observer. So again, in

0:24:56.480 --> 0:24:59.400
<v Speaker 1>other words, like if I if I'm standing perfectly still

0:24:59.800 --> 0:25:02.600
<v Speaker 1>in space, so I'm not, I'm not on a planet,

0:25:02.640 --> 0:25:06.320
<v Speaker 1>I'm not moving at all, hopefully in space suit Yes, sure,

0:25:06.760 --> 0:25:08.080
<v Speaker 1>why not? I'll give it to you at this time,

0:25:08.160 --> 0:25:11.720
<v Speaker 1>all right, And Lauren, you are in a zippy little

0:25:11.800 --> 0:25:14.960
<v Speaker 1>ship that's going at near the speed of light. Again,

0:25:15.040 --> 0:25:18.120
<v Speaker 1>to you, time seems to be passing at the normal rate.

0:25:18.520 --> 0:25:20.480
<v Speaker 1>Like if you were to have a watch watch, it

0:25:20.520 --> 0:25:22.960
<v Speaker 1>would be taking along at one second partick according to

0:25:23.000 --> 0:25:25.879
<v Speaker 1>my eyeballs, right, and it would feel exactly like it

0:25:26.040 --> 0:25:29.240
<v Speaker 1>was as long as a second should be. My watch

0:25:29.359 --> 0:25:32.240
<v Speaker 1>would also to me be it would appear to be

0:25:32.320 --> 0:25:36.400
<v Speaker 1>moving at exactly the correct speed. Now, if I were

0:25:36.600 --> 0:25:39.920
<v Speaker 1>to to be able to see what's happening in your

0:25:40.000 --> 0:25:42.680
<v Speaker 1>little world, it would look to me like a time

0:25:42.800 --> 0:25:46.600
<v Speaker 1>had slowed way down for you, and that more time

0:25:47.200 --> 0:25:49.240
<v Speaker 1>was passing for me than it was for you, so

0:25:49.760 --> 0:25:52.119
<v Speaker 1>you could do like a quick joy ride around the

0:25:52.359 --> 0:25:55.679
<v Speaker 1>solar system. And let's say we're just going to make

0:25:55.680 --> 0:25:58.120
<v Speaker 1>an argument that that you take an hour long trip

0:25:58.280 --> 0:26:01.600
<v Speaker 1>around the solar system and to me, to to your

0:26:01.800 --> 0:26:05.120
<v Speaker 1>to your watch, so your watch, you start the timer

0:26:05.160 --> 0:26:07.920
<v Speaker 1>as soon as you engage the drive, and an hour

0:26:08.040 --> 0:26:10.280
<v Speaker 1>has gone by, and you you come back and pick

0:26:10.280 --> 0:26:12.359
<v Speaker 1>you up, you come back to see me, and uh,

0:26:12.520 --> 0:26:14.680
<v Speaker 1>and we're gonna say that you're going on a speed

0:26:14.760 --> 0:26:17.400
<v Speaker 1>so that we won't make it ridiculous. So were you're

0:26:17.400 --> 0:26:20.040
<v Speaker 1>going at a speed where a year of time has

0:26:20.080 --> 0:26:23.399
<v Speaker 1>gone by for me? I'm going to Chris speed. Sorry, So,

0:26:23.760 --> 0:26:25.600
<v Speaker 1>so an hour of time has gone by for Lauren,

0:26:25.680 --> 0:26:29.000
<v Speaker 1>a year has gone by for me. Um, And that's

0:26:29.160 --> 0:26:33.480
<v Speaker 1>the special relativity. It's that idea that again relative to me,

0:26:34.400 --> 0:26:36.960
<v Speaker 1>less time has passed for Lauren. Relative to Lauren, more

0:26:37.000 --> 0:26:39.400
<v Speaker 1>time has passed for me. Right, And then that's because

0:26:39.440 --> 0:26:42.680
<v Speaker 1>that's because speed and mass both have speed and gravity

0:26:42.800 --> 0:26:45.560
<v Speaker 1>both have an effect on time, as time is a

0:26:45.600 --> 0:26:49.520
<v Speaker 1>substance itself. So now the gravity mass thing that's really

0:26:49.600 --> 0:26:52.960
<v Speaker 1>more general relativity. But that's that's also playing a part

0:26:53.440 --> 0:26:56.200
<v Speaker 1>in all of our calculations when it comes to space faring.

0:26:56.600 --> 0:26:59.000
<v Speaker 1>By the way, if you were to do something like

0:26:59.200 --> 0:27:02.879
<v Speaker 1>Carrie and a my clock, uh, and have it synchronized

0:27:02.920 --> 0:27:05.600
<v Speaker 1>within another atomic clock. So two atomic clocks are side

0:27:05.640 --> 0:27:08.359
<v Speaker 1>by side on a table here on Earth, and you

0:27:08.480 --> 0:27:12.080
<v Speaker 1>take one of those and you get on an air elevator.

0:27:12.640 --> 0:27:14.119
<v Speaker 1>Is not even a space all there. You just get

0:27:14.200 --> 0:27:16.800
<v Speaker 1>an airplane. And as an airplane is going at top

0:27:16.920 --> 0:27:19.359
<v Speaker 1>speed and it's flying as far as it possibly can

0:27:19.480 --> 0:27:21.600
<v Speaker 1>and then it lands. By the time it lands, those

0:27:21.640 --> 0:27:24.080
<v Speaker 1>two clocks that were in perfect sink before will no

0:27:24.200 --> 0:27:26.320
<v Speaker 1>longer be in perfect sinc And the reason is is

0:27:26.400 --> 0:27:29.679
<v Speaker 1>that you were traveling a little faster. There's also some uh,

0:27:30.000 --> 0:27:34.120
<v Speaker 1>the element of general relativity, which means that when you're

0:27:34.160 --> 0:27:35.879
<v Speaker 1>further away from the center of the Earth and and

0:27:35.960 --> 0:27:39.640
<v Speaker 1>therefore the closer you are to a large mass object,

0:27:40.200 --> 0:27:44.520
<v Speaker 1>the slower time passes for you relative to something that's

0:27:44.520 --> 0:27:47.400
<v Speaker 1>further out from that massive object. Again, it's all relative

0:27:47.840 --> 0:27:50.600
<v Speaker 1>because from your individual experience, it seems like time is

0:27:50.680 --> 0:27:52.920
<v Speaker 1>passing at the same rate unless you're you know, waiting

0:27:52.960 --> 0:27:55.159
<v Speaker 1>on an important phone call, in which case, yeah, like

0:27:55.320 --> 0:27:58.840
<v Speaker 1>you know that that dreamy, that dreamy person you met

0:27:58.880 --> 0:28:00.639
<v Speaker 1>at that party is supposed to call and you're just

0:28:00.720 --> 0:28:03.360
<v Speaker 1>staring at the phone. Tie. Every second is an eternity,

0:28:03.440 --> 0:28:05.159
<v Speaker 1>no matter whether you're traveling at the speed of light

0:28:05.240 --> 0:28:07.040
<v Speaker 1>or not. But anyway, yeah, we can observe this in

0:28:07.119 --> 0:28:09.280
<v Speaker 1>it in satellites that we've launched into orbit, they have

0:28:09.400 --> 0:28:12.920
<v Speaker 1>to they have to mathematically correct for that sort of Yeah. So,

0:28:13.000 --> 0:28:16.120
<v Speaker 1>in fact, both special and general relativity play a part

0:28:16.160 --> 0:28:20.720
<v Speaker 1>in this. So the Global Positioning System GPS, the GPS

0:28:21.280 --> 0:28:24.680
<v Speaker 1>device you have picks up signals that are beamed down

0:28:24.920 --> 0:28:28.920
<v Speaker 1>from satellites, and the satellites part of the signal is

0:28:28.960 --> 0:28:31.560
<v Speaker 1>a time stamp, and the way your GPS figures out

0:28:31.600 --> 0:28:34.080
<v Speaker 1>where you are is by saying, all right, well, it

0:28:34.160 --> 0:28:37.359
<v Speaker 1>took X amount of time for for this one signal

0:28:37.480 --> 0:28:40.040
<v Speaker 1>to come from this satellite to hit me, It took

0:28:40.240 --> 0:28:42.560
<v Speaker 1>x amount why amount of time from the signal from

0:28:42.600 --> 0:28:44.880
<v Speaker 1>this other satellite hit me, and took the amount of

0:28:44.960 --> 0:28:47.560
<v Speaker 1>time for the signal from this third satellite to hit me.

0:28:47.840 --> 0:28:50.160
<v Speaker 1>Based upon all of that and the position of those satellites,

0:28:50.240 --> 0:28:52.640
<v Speaker 1>I know that I must be on this point on

0:28:52.800 --> 0:28:56.160
<v Speaker 1>the Earth. Well, obviously the time stamp is really important

0:28:56.200 --> 0:28:59.280
<v Speaker 1>for the information to work. It needs to be pretty precise, yeah,

0:28:59.360 --> 0:29:02.480
<v Speaker 1>otherwise it's going to give you the wrong location on

0:29:02.640 --> 0:29:05.000
<v Speaker 1>the Earth. The thing about the satellites is that they

0:29:05.080 --> 0:29:09.400
<v Speaker 1>are traveling faster than a point relative on the surface

0:29:09.480 --> 0:29:12.040
<v Speaker 1>of the Earth, so that means that time is passing

0:29:12.520 --> 0:29:16.160
<v Speaker 1>again at a different rate relative to us here on

0:29:16.280 --> 0:29:18.960
<v Speaker 1>Earth on the on the surface. But they are also

0:29:19.080 --> 0:29:21.840
<v Speaker 1>further out from the mass of the Earth, which means

0:29:22.040 --> 0:29:24.560
<v Speaker 1>they're going faster, So that means times passing more slowly

0:29:24.600 --> 0:29:26.680
<v Speaker 1>relative to us. But they are further out, so time

0:29:26.760 --> 0:29:30.760
<v Speaker 1>is passing faster than relative to us. This gets really complicated,

0:29:31.520 --> 0:29:34.080
<v Speaker 1>but if you were talking about just special relativity, because

0:29:34.120 --> 0:29:36.840
<v Speaker 1>the satellites are moving so fast, they have about a

0:29:36.920 --> 0:29:40.160
<v Speaker 1>lag of about seven micro seconds per day on the

0:29:40.200 --> 0:29:43.440
<v Speaker 1>satellites clock. So remember they're they're traveling faster than the

0:29:43.920 --> 0:29:45.880
<v Speaker 1>relative point on the surface of the Earth, so that

0:29:45.960 --> 0:29:49.880
<v Speaker 1>means that less time is passing on the satellite seven

0:29:49.960 --> 0:29:52.520
<v Speaker 1>micro seconds per day as a as a result. But

0:29:52.840 --> 0:29:54.880
<v Speaker 1>because they're further out from the mass of the Earth,

0:29:54.960 --> 0:29:57.560
<v Speaker 1>then a clock would be here, you know, close to

0:29:57.640 --> 0:30:01.520
<v Speaker 1>the surface. Their clocks are actually running faster by about

0:30:01.600 --> 0:30:05.800
<v Speaker 1>forty five microseconds per day because of general relativity. So

0:30:06.000 --> 0:30:08.720
<v Speaker 1>if you take those two numbers, the the lag of

0:30:08.840 --> 0:30:13.520
<v Speaker 1>second seven microseconds and the surplus of forty five microseconds,

0:30:13.560 --> 0:30:16.000
<v Speaker 1>and then you know, combine the two to cancel them out,

0:30:16.400 --> 0:30:19.320
<v Speaker 1>you are still left with a thirty eight microseconds surplus

0:30:19.560 --> 0:30:22.600
<v Speaker 1>per day on the satellites clock compared to one on Earth.

0:30:23.280 --> 0:30:25.040
<v Speaker 1>So that means that you actually have to correct for that.

0:30:25.800 --> 0:30:28.960
<v Speaker 1>All right, that's one satellite that's orbiting Earth. Now imagine

0:30:29.000 --> 0:30:33.160
<v Speaker 1>that on all the spaceships traveling everywhere all the time.

0:30:33.520 --> 0:30:35.640
<v Speaker 1>And that's why you get to the point where keeping

0:30:35.920 --> 0:30:38.720
<v Speaker 1>track of time is an impossible actic level is Yeah,

0:30:39.160 --> 0:30:41.440
<v Speaker 1>So in the case of Han Solo, again going back

0:30:41.480 --> 0:30:45.080
<v Speaker 1>to that that Wired article that Kyle Hill wrote, he

0:30:45.280 --> 0:30:48.640
<v Speaker 1>started pointing out that assuming that you're going at near

0:30:48.720 --> 0:30:50.920
<v Speaker 1>the speed of light. He went ahead and said, okay,

0:30:50.960 --> 0:30:52.960
<v Speaker 1>you can't go faster than speed of light. Yeah, let's

0:30:53.000 --> 0:30:54.920
<v Speaker 1>let's that's right out. And going at the speed of

0:30:55.040 --> 0:30:57.080
<v Speaker 1>light is also impossible because you would at that point

0:30:57.160 --> 0:31:01.080
<v Speaker 1>have infinite density, density, and and mass. So that would

0:31:01.080 --> 0:31:04.560
<v Speaker 1>be bad mass. Your mass increases as you get closer

0:31:04.640 --> 0:31:08.720
<v Speaker 1>to the speed of light. But if we say ad infinitum, yeah,

0:31:09.240 --> 0:31:11.800
<v Speaker 1>so it's going about as fast as it as as

0:31:12.120 --> 0:31:14.240
<v Speaker 1>as close to the speed of light as you possibly

0:31:14.560 --> 0:31:18.520
<v Speaker 1>can imagine. This is probably not it's probably not ever

0:31:18.680 --> 0:31:21.760
<v Speaker 1>going to be possible physically, but if you can imagine

0:31:21.840 --> 0:31:25.800
<v Speaker 1>it um that, then the Kessel run would take about

0:31:25.920 --> 0:31:29.320
<v Speaker 1>half a day, about sixteen hours yea, so sixteen hours

0:31:29.400 --> 0:31:32.840
<v Speaker 1>on the on the Millennium Falcon. But then galactic time,

0:31:32.960 --> 0:31:35.680
<v Speaker 1>assuming the galactic time is passing at a stands to

0:31:37.160 --> 0:31:40.440
<v Speaker 1>forty years, So forty years would pass in galactic time

0:31:40.480 --> 0:31:44.719
<v Speaker 1>while on board the Falcon, sixteen hours passes. So they

0:31:44.760 --> 0:31:48.400
<v Speaker 1>started to figure out like how much time has passed

0:31:48.480 --> 0:31:52.640
<v Speaker 1>in the gal and the galaxy since Han Solo made

0:31:52.760 --> 0:31:55.360
<v Speaker 1>his Kessel run, And then he started saying, well, yeahs

0:31:55.680 --> 0:31:58.320
<v Speaker 1>probably made the Kessel run more than once, so if

0:31:58.360 --> 0:32:01.400
<v Speaker 1>you start adding up to of Kessel runs, how much

0:32:01.440 --> 0:32:03.320
<v Speaker 1>time has passed. And that's when he said, like, you know,

0:32:03.480 --> 0:32:05.280
<v Speaker 1>you do two Kestle runs. And then he had to

0:32:05.360 --> 0:32:11.040
<v Speaker 1>have been born before characters who like cook. Yeah, so

0:32:11.880 --> 0:32:15.640
<v Speaker 1>then you've got Han Solo predating all the characters who

0:32:15.960 --> 0:32:18.760
<v Speaker 1>were in the prequels. Uh, and it's because of this

0:32:18.840 --> 0:32:22.920
<v Speaker 1>special relativity problem. So, by the way, if he were

0:32:23.120 --> 0:32:25.880
<v Speaker 1>in fact able to travel faster than the speed of light,

0:32:26.200 --> 0:32:28.680
<v Speaker 1>it would mean that he would arrive at his destination

0:32:28.840 --> 0:32:33.040
<v Speaker 1>before he left math is fun. Yeah, so so he

0:32:33.080 --> 0:32:36.719
<v Speaker 1>would actually he would be on Kessel before he had

0:32:36.800 --> 0:32:41.680
<v Speaker 1>decided to make the Kessel run due to the way

0:32:41.920 --> 0:32:44.080
<v Speaker 1>this works. Now, granted, nothing can go faster than the

0:32:44.080 --> 0:32:47.520
<v Speaker 1>speed of light. But you know, assuming they have they

0:32:47.560 --> 0:32:50.840
<v Speaker 1>have those those drives, those that the hyper drives, ret

0:32:50.920 --> 0:32:54.120
<v Speaker 1>red con drives, the red con drives. Yes, those work

0:32:54.200 --> 0:32:57.920
<v Speaker 1>really well. Um where you just say, hey, it's impossible,

0:32:58.000 --> 0:33:00.520
<v Speaker 1>let's change it. Let's look at the wookie. Uh. And

0:33:00.760 --> 0:33:03.680
<v Speaker 1>and so the stasis field was sort of the answer

0:33:03.720 --> 0:33:07.200
<v Speaker 1>to that, saying that the time does not pass differently

0:33:07.320 --> 0:33:09.840
<v Speaker 1>aboard the ship as it does in the outside galaxy,

0:33:10.080 --> 0:33:12.120
<v Speaker 1>which is fine except for the fact that again, remember,

0:33:12.160 --> 0:33:15.560
<v Speaker 1>every single planet has its own passage of time. Like

0:33:15.800 --> 0:33:18.040
<v Speaker 1>you know, a second feels like a second no matter

0:33:18.080 --> 0:33:21.640
<v Speaker 1>where you are, but it lasts shorter or longer depending

0:33:21.720 --> 0:33:24.200
<v Speaker 1>upon the planet's mass and its speed that it moves

0:33:24.240 --> 0:33:27.440
<v Speaker 1>through space. And also technically, I think that it would

0:33:27.440 --> 0:33:29.720
<v Speaker 1>be a little bit confusing to try to, you know,

0:33:30.320 --> 0:33:33.160
<v Speaker 1>call days out on a whole system of planets that

0:33:33.240 --> 0:33:37.000
<v Speaker 1>have different suns and different orbits, and yeah, and and tattooing.

0:33:37.160 --> 0:33:39.400
<v Speaker 1>You've got two sons, one of them might always be up.

0:33:39.440 --> 0:33:41.840
<v Speaker 1>You never know, I mean, it's it gets complex and

0:33:42.120 --> 0:33:44.680
<v Speaker 1>uh yeah, And then you have all these other people

0:33:44.840 --> 0:33:47.880
<v Speaker 1>who are traveling around at nearer or faster than the

0:33:47.960 --> 0:33:50.600
<v Speaker 1>speed of lights, so time gets messed up for them too,

0:33:50.800 --> 0:33:54.840
<v Speaker 1>So time would be meaningless in this universe, which you know,

0:33:55.320 --> 0:33:58.560
<v Speaker 1>one could argue it's kind of meaningless now, but I

0:33:58.640 --> 0:34:01.880
<v Speaker 1>don't get that cynical except on Friday's and it's a Thursday,

0:34:01.960 --> 0:34:04.800
<v Speaker 1>so I'm all right. Then again, there are also some

0:34:04.920 --> 0:34:07.800
<v Speaker 1>criticisms to things like the visual representation of what it

0:34:07.840 --> 0:34:11.399
<v Speaker 1>looks like to go into hyperspace, which I thought was awesome. Yeah, yeah,

0:34:11.440 --> 0:34:13.560
<v Speaker 1>there there was a study that was done by did

0:34:13.600 --> 0:34:14.960
<v Speaker 1>that study I don't have it in front of some

0:34:15.080 --> 0:34:20.080
<v Speaker 1>students Riley Connor's, Katie Dexter, Joshua Argyle and Cameron's school

0:34:20.120 --> 0:34:22.760
<v Speaker 1>are and they said that if you were to travel

0:34:22.840 --> 0:34:24.520
<v Speaker 1>at the speed of light, not only would you not

0:34:24.920 --> 0:34:28.880
<v Speaker 1>see those stars become streaks, they would become a cone

0:34:28.960 --> 0:34:30.880
<v Speaker 1>of light, so the center would be the brightest and

0:34:30.960 --> 0:34:33.239
<v Speaker 1>the further out from the cone, the darker it would get.

0:34:33.920 --> 0:34:35.680
<v Speaker 1>And uh, and part of that is because of the

0:34:35.760 --> 0:34:38.959
<v Speaker 1>Doppler effect essentially, right, right, that's that's that's blue shift

0:34:39.000 --> 0:34:41.359
<v Speaker 1>and redshift. And yes, when you're when you're when you're

0:34:41.400 --> 0:34:43.360
<v Speaker 1>moving and near the speed of light or at the

0:34:43.360 --> 0:34:46.320
<v Speaker 1>speed of light towards something, um, everything is going to

0:34:46.400 --> 0:34:50.440
<v Speaker 1>shift towards blue. Yeah. The waves compressed because you're you're

0:34:50.800 --> 0:34:54.440
<v Speaker 1>traveling toward the the emanation of those waves, so they

0:34:54.440 --> 0:34:56.279
<v Speaker 1>are being compressed further and further. In fact, that would

0:34:56.280 --> 0:34:59.080
<v Speaker 1>be compressed so much as to move outside the visible

0:34:59.200 --> 0:35:01.759
<v Speaker 1>spectrum and then you would start getting hit by lots

0:35:01.800 --> 0:35:03.880
<v Speaker 1>of X rays, which would tell you that your spaceship

0:35:04.000 --> 0:35:06.279
<v Speaker 1>needs to have some real protection built into it or

0:35:06.320 --> 0:35:08.319
<v Speaker 1>else people are not going to feel so great when

0:35:08.360 --> 0:35:11.319
<v Speaker 1>they get to where they're going. Uh. And that's an

0:35:11.360 --> 0:35:13.799
<v Speaker 1>interesting point too. Yeah, And I didn't even think about

0:35:13.840 --> 0:35:17.080
<v Speaker 1>that until I read this little study, and I thought, well,

0:35:17.160 --> 0:35:19.520
<v Speaker 1>that's pretty clever. Yeah, I guess. So the Doubler effect

0:35:19.560 --> 0:35:22.760
<v Speaker 1>would would be something you'd have to take into account,

0:35:22.800 --> 0:35:25.640
<v Speaker 1>so it wouldn't look like those stars flying by the

0:35:25.719 --> 0:35:29.200
<v Speaker 1>way they do in the movies. UM, So we wanted

0:35:29.239 --> 0:35:32.480
<v Speaker 1>to talk a little bit conclude with a discussion about

0:35:32.560 --> 0:35:36.960
<v Speaker 1>some actual real propulsion systems besides chemical rockets. Now we

0:35:37.040 --> 0:35:40.480
<v Speaker 1>don't have a hyperdrive, which is unfortunate. We would love

0:35:40.560 --> 0:35:43.560
<v Speaker 1>to have one, obviously, would be really handy, you guys,

0:35:43.600 --> 0:35:46.160
<v Speaker 1>get on that. Yeah, but right now we don't have one.

0:35:46.560 --> 0:35:49.960
<v Speaker 1>So some of the propulsion systems have been proposed for

0:35:51.040 --> 0:35:55.359
<v Speaker 1>for for space travel beyond. We're getting outside the whole

0:35:55.400 --> 0:35:57.799
<v Speaker 1>thing about launching off the Earth. I mean that that part.

0:35:57.880 --> 0:36:00.760
<v Speaker 1>You still pretty much need chemical rockets, solid fuel rockets

0:36:01.440 --> 0:36:05.200
<v Speaker 1>to provide the propulsion you need to get off the planet,

0:36:05.360 --> 0:36:08.680
<v Speaker 1>right because the amount of power involved what we can

0:36:08.760 --> 0:36:11.080
<v Speaker 1>do with chemical right now is a lot more. Um

0:36:11.719 --> 0:36:14.200
<v Speaker 1>it gives a lot more, a lot more. That's this

0:36:14.760 --> 0:36:19.440
<v Speaker 1>astronomical term, and there's a plenty in a chemical rocket. Guys.

0:36:19.480 --> 0:36:21.959
<v Speaker 1>We just popped out of hyperspace for just a moment,

0:36:22.040 --> 0:36:23.840
<v Speaker 1>so we can take another quick break, but we'll be

0:36:24.080 --> 0:36:34.319
<v Speaker 1>right back. These other drives would be very useful once

0:36:34.360 --> 0:36:37.040
<v Speaker 1>you do get up into space where you don't have

0:36:37.160 --> 0:36:39.840
<v Speaker 1>to have the considerations of escaping a planet's gravity or

0:36:39.920 --> 0:36:43.520
<v Speaker 1>battling its atmosphere in order to maneuver, right, because the

0:36:43.560 --> 0:36:45.640
<v Speaker 1>thing about about these chemical drives is that they are

0:36:45.880 --> 0:36:49.840
<v Speaker 1>extremely wasteful in a grand universal kind of scheme. You

0:36:49.920 --> 0:36:52.040
<v Speaker 1>have to carry a lot of fuel. They pack a

0:36:52.080 --> 0:36:53.960
<v Speaker 1>lot of power, but you have to carry an awful

0:36:54.000 --> 0:36:58.160
<v Speaker 1>lot of it's not terribly efficient. Uh So they wouldn't

0:36:58.239 --> 0:37:00.560
<v Speaker 1>last very long in the grand scheme of things. If

0:37:00.600 --> 0:37:04.400
<v Speaker 1>you're talking about trying to travel vast different distances, not differences,

0:37:04.440 --> 0:37:09.439
<v Speaker 1>but distances, then the chemical uh rockets end up being

0:37:09.719 --> 0:37:13.680
<v Speaker 1>really heavy and that limits how much you can carry,

0:37:13.800 --> 0:37:16.000
<v Speaker 1>which in turn limits how far you can go so

0:37:16.239 --> 0:37:19.400
<v Speaker 1>without just coasting like for example, the voice your satellites

0:37:19.600 --> 0:37:22.760
<v Speaker 1>right right, which, hey, just left the Solar system. Actually

0:37:22.880 --> 0:37:27.919
<v Speaker 1>they didn't. They come back. Yeah, you have left something

0:37:27.960 --> 0:37:30.719
<v Speaker 1>on Pluto. Um no, they that was that was a

0:37:30.800 --> 0:37:33.879
<v Speaker 1>little bit of a miss misquote in the press. Oh nice. Yeah,

0:37:34.000 --> 0:37:35.920
<v Speaker 1>Well I'm glad you. I'm glad you caught up on that,

0:37:35.960 --> 0:37:39.719
<v Speaker 1>because obviously I did not failed to tweet about it,

0:37:39.840 --> 0:37:44.239
<v Speaker 1>so well, I'm that's bad. Hey, No, it's okay, you

0:37:44.360 --> 0:37:46.600
<v Speaker 1>caught it on the podcast. So now our listeners can

0:37:46.640 --> 0:37:50.600
<v Speaker 1>say that vogo bomb she keeps Strickland on task. So

0:37:51.200 --> 0:37:52.440
<v Speaker 1>one of the ones we want to talk about where

0:37:52.480 --> 0:37:56.239
<v Speaker 1>ion engines. Now ion engines, they're using ions, and so

0:37:56.440 --> 0:38:00.200
<v Speaker 1>that's charged particles. Um. You know, think of an them

0:38:00.280 --> 0:38:05.120
<v Speaker 1>that's either either has an excess of electrons or a

0:38:05.760 --> 0:38:08.640
<v Speaker 1>deficit in electrons, so either way to either a negative

0:38:08.680 --> 0:38:13.120
<v Speaker 1>or positive charge. Plasma is an ionic gas, So it's

0:38:13.120 --> 0:38:15.680
<v Speaker 1>a gas that has these free ions moving through. It

0:38:15.800 --> 0:38:18.320
<v Speaker 1>means that you can actually pass electric current through the

0:38:18.440 --> 0:38:21.399
<v Speaker 1>gas itself. That's what a plasma is. A positible, of course,

0:38:21.480 --> 0:38:25.759
<v Speaker 1>is the most plentiful of the states of matter in

0:38:25.840 --> 0:38:29.040
<v Speaker 1>the universe as far as we are aware. And um.

0:38:29.520 --> 0:38:33.000
<v Speaker 1>And so the ion engines use electric fields rather than

0:38:33.080 --> 0:38:36.280
<v Speaker 1>chemical reactions to create propulsion, and they're not as powerful

0:38:36.320 --> 0:38:38.800
<v Speaker 1>as chemical engines, so they don't give you that the

0:38:38.880 --> 0:38:42.440
<v Speaker 1>chemical engines do, but they are way more efficient, so

0:38:42.560 --> 0:38:46.000
<v Speaker 1>they can last ages, and they use the solar energy

0:38:46.120 --> 0:38:48.640
<v Speaker 1>to provide that. Yeah, they get the solar energy to

0:38:48.719 --> 0:38:52.680
<v Speaker 1>provide electricity to help create these reactions that will create

0:38:52.719 --> 0:38:57.120
<v Speaker 1>the ions that that propel it. So they have these

0:38:57.160 --> 0:38:59.959
<v Speaker 1>big solar panels that will unfold from the space craft.

0:39:00.440 --> 0:39:04.440
<v Speaker 1>We've already launched some spacecraft using ion engines. The Dawn spacecraft,

0:39:04.480 --> 0:39:07.359
<v Speaker 1>which launched on September twenty seventh, two thousand seven, has

0:39:07.440 --> 0:39:11.440
<v Speaker 1>ion engines and uses the solar panels to get the electricity.

0:39:11.800 --> 0:39:15.920
<v Speaker 1>UM it's destination it had to actually, but the second destination,

0:39:16.000 --> 0:39:19.799
<v Speaker 1>the ultimate destination, is a dwarf planet series, and it's

0:39:19.800 --> 0:39:24.840
<v Speaker 1>scheduled to arrive there in February. Uh So, visiting the

0:39:24.960 --> 0:39:29.280
<v Speaker 1>NASA pages about this spacecraft, I saw some interesting figures.

0:39:29.640 --> 0:39:32.000
<v Speaker 1>One was that it is a six point three billion

0:39:32.120 --> 0:39:35.160
<v Speaker 1>kilometer journey, and just so that you get an idea

0:39:35.160 --> 0:39:36.960
<v Speaker 1>of how far that is compared to a light year.

0:39:37.040 --> 0:39:40.239
<v Speaker 1>A light year is nine point four trillion kilometers, so

0:39:40.360 --> 0:39:43.440
<v Speaker 1>six point three billion kilometers still nowhere near a light year.

0:39:44.080 --> 0:39:47.800
<v Speaker 1>So it assuming that it arrives on the first of February,

0:39:47.920 --> 0:39:52.080
<v Speaker 1>in which you know, that's I just took as an arbitrary. Yeah,

0:39:52.800 --> 0:39:56.200
<v Speaker 1>it will have flown for seven years, five months, and

0:39:56.360 --> 0:39:59.280
<v Speaker 1>two days to go those six point three billion kilometers,

0:39:59.520 --> 0:40:02.359
<v Speaker 1>so I it's him. I did some silly little math

0:40:02.480 --> 0:40:06.640
<v Speaker 1>which was that six million, six point three billion kilometers

0:40:06.719 --> 0:40:09.680
<v Speaker 1>ends up being six point three trillion meters, and then

0:40:10.000 --> 0:40:12.279
<v Speaker 1>you have to figure out how many seconds are in

0:40:12.400 --> 0:40:15.080
<v Speaker 1>seven years five months and two days, So I did

0:40:15.760 --> 0:40:19.440
<v Speaker 1>two hundred six million, hundred seconds. So if you do

0:40:19.600 --> 0:40:22.680
<v Speaker 1>the math, then that means that the average speed, and

0:40:22.840 --> 0:40:25.280
<v Speaker 1>this is you know, just an average because it does change,

0:40:25.719 --> 0:40:29.000
<v Speaker 1>is twenty six thousand, five nine seven per second based

0:40:29.080 --> 0:40:31.920
<v Speaker 1>on the information that I was able to find. So uh,

0:40:33.280 --> 0:40:36.120
<v Speaker 1>I mean, not shabby, but still nowhere near the streets

0:40:36.160 --> 0:40:40.200
<v Speaker 1>of the falcon. Uh. But it also used about uses.

0:40:40.360 --> 0:40:45.320
<v Speaker 1>The Dawn's engine used fos of xenon fuel being a

0:40:45.400 --> 0:40:48.360
<v Speaker 1>neutral ly charged yeah, and it used that the solar

0:40:48.480 --> 0:40:52.959
<v Speaker 1>array to to ionize everything's uh. And the solar array

0:40:53.200 --> 0:40:58.320
<v Speaker 1>at one astronomical unit provided about ten point three kilowatts

0:40:58.440 --> 0:41:03.200
<v Speaker 1>of power. UH. Astronomical unit, by the way, is one million,

0:41:03.800 --> 0:41:06.160
<v Speaker 1>seven thousand and seventy one kilometers. And you might say, well,

0:41:06.239 --> 0:41:09.080
<v Speaker 1>what the heck kind of measurement is that, Well, that's

0:41:09.120 --> 0:41:12.400
<v Speaker 1>the mean distance between the Earth and the Sun. Because

0:41:12.440 --> 0:41:16.279
<v Speaker 1>the distance actually changes throughout the Earth's rotation around the Sun,

0:41:16.360 --> 0:41:19.080
<v Speaker 1>it's not always exactly that far away. That's the mean.

0:41:19.920 --> 0:41:22.600
<v Speaker 1>So that's what we decided to define as an astronomical unit.

0:41:22.640 --> 0:41:24.960
<v Speaker 1>And I'm sure any aliens will be happy to take

0:41:25.080 --> 0:41:30.400
<v Speaker 1>us up on a discussion of why that's very human centric. Yes,

0:41:30.440 --> 0:41:34.040
<v Speaker 1>an astronomical unit is exactly the distance between your star

0:41:34.320 --> 0:41:37.960
<v Speaker 1>and your planet. Really enlightened, guys, I mean I think

0:41:38.000 --> 0:41:40.799
<v Speaker 1>that they'll really take onto it, like parsex. Yeah, they'll

0:41:40.840 --> 0:41:43.960
<v Speaker 1>be right up there. They're like I was having this

0:41:44.040 --> 0:41:49.080
<v Speaker 1>discussion with my buddy eight parsecs ago, like, oh, come on, Like, hey,

0:41:49.160 --> 0:41:51.239
<v Speaker 1>I know how this goes because I watched your Star

0:41:51.280 --> 0:41:55.240
<v Speaker 1>Wars documentary. So at the maximum thrust, Don's ion engine

0:41:55.320 --> 0:41:58.920
<v Speaker 1>expands about point to five ms of xenon per day,

0:41:59.360 --> 0:42:02.480
<v Speaker 1>and that produced is a thrust of ninety two million Newton's,

0:42:03.040 --> 0:42:05.719
<v Speaker 1>which NASA explains is about the amount of force you

0:42:05.800 --> 0:42:07.960
<v Speaker 1>feel when you put a piece of paper on your

0:42:08.040 --> 0:42:11.160
<v Speaker 1>open hand. That's the amount of force which sounds so

0:42:11.480 --> 0:42:15.400
<v Speaker 1>incredibly unimpressive when you write, but in the in the

0:42:15.600 --> 0:42:19.440
<v Speaker 1>in the environment of space, it is plenty enough. And

0:42:19.719 --> 0:42:23.399
<v Speaker 1>uh so it says that the thrust changes the space

0:42:23.440 --> 0:42:27.520
<v Speaker 1>cust velocity about oh ten to the negative five meters

0:42:27.560 --> 0:42:30.520
<v Speaker 1>per second every second, and after about a thousand days

0:42:30.560 --> 0:42:33.160
<v Speaker 1>it would achieve a velocity of a thousand meters per second.

0:42:33.239 --> 0:42:39.080
<v Speaker 1>So because there's no dragon space exactly. Yeah, So anyway, yeah,

0:42:39.320 --> 0:42:41.759
<v Speaker 1>about a thousand meters a second after a thousand days.

0:42:42.400 --> 0:42:44.319
<v Speaker 1>So that that that speed I gave you the twenty

0:42:44.320 --> 0:42:48.320
<v Speaker 1>six seven per second. Obviously, again that's a that's just

0:42:48.520 --> 0:42:51.120
<v Speaker 1>averaging it out over the full distance. In fact, it's

0:42:51.160 --> 0:42:55.719
<v Speaker 1>just constantly accelerating, not always at that particular speed, but

0:42:55.920 --> 0:42:58.520
<v Speaker 1>it will be or at that particular rate. I shouldn't

0:42:58.520 --> 0:43:01.600
<v Speaker 1>say it's accelerating at that speed, that's totally it's not misleading,

0:43:01.960 --> 0:43:05.239
<v Speaker 1>but at that rate. So yeah, that's that's one of

0:43:05.280 --> 0:43:07.160
<v Speaker 1>the ones that we're looking at. Now. There's also other

0:43:08.040 --> 0:43:12.160
<v Speaker 1>forms of propulsion that have been proposed, like solar sales. Again,

0:43:12.360 --> 0:43:16.200
<v Speaker 1>not something that's going to get you from Earth's solar

0:43:16.320 --> 0:43:20.200
<v Speaker 1>system to a distant solar system anytime quickly. Um, it's

0:43:20.280 --> 0:43:25.440
<v Speaker 1>more of a very efficient means of travel by harnessing photons.

0:43:25.640 --> 0:43:27.840
<v Speaker 1>The photons hit the solar sale and that's what provides

0:43:27.880 --> 0:43:31.000
<v Speaker 1>the propulsion to move the craft forward, which sounds kind

0:43:31.000 --> 0:43:33.319
<v Speaker 1>of incredible you think about that. You know, how much

0:43:33.840 --> 0:43:37.440
<v Speaker 1>kinetic energy can a photon have? Uh, And and it

0:43:37.520 --> 0:43:39.840
<v Speaker 1>may surprise some of you to know that photons have

0:43:39.960 --> 0:43:43.240
<v Speaker 1>kinetic energy, but that's true. I mean the Earth actually

0:43:44.160 --> 0:43:47.080
<v Speaker 1>when the sun is hitting you you weigh a little

0:43:47.239 --> 0:43:52.920
<v Speaker 1>more because the light is actually hitting Yeah. Yeah, that's

0:43:52.960 --> 0:43:55.800
<v Speaker 1>why I never go outside and only getting pushed around

0:43:56.120 --> 0:44:00.120
<v Speaker 1>by the sun or by nobody. And so, uh, then

0:44:00.160 --> 0:44:02.880
<v Speaker 1>I wanted to mention there's a theoretical engine. There's a

0:44:02.960 --> 0:44:05.239
<v Speaker 1>there's a few theoretical engines. Yeah. The one that I

0:44:05.320 --> 0:44:11.400
<v Speaker 1>came across was an electromagnetic gravity drive by Yachoum Howser.

0:44:11.840 --> 0:44:14.080
<v Speaker 1>That's just a guess because I don't know how to

0:44:14.360 --> 0:44:17.000
<v Speaker 1>pronounce that name. I do not either. That sounds great

0:44:17.040 --> 0:44:18.880
<v Speaker 1>to me. Well, he's a physicist and a professor of

0:44:18.920 --> 0:44:21.759
<v Speaker 1>computer science at the University Applied Sciences in a soul

0:44:21.880 --> 0:44:27.120
<v Speaker 1>skitter and uh. And then he worked with Volter Drusher,

0:44:27.719 --> 0:44:31.960
<v Speaker 1>who was an Austrian patent officer, and they came up

0:44:32.080 --> 0:44:35.600
<v Speaker 1>with an idea that would use an electromagnet, essentially a

0:44:35.800 --> 0:44:40.160
<v Speaker 1>rotating ring above a super conducting coil, and then they

0:44:40.200 --> 0:44:43.759
<v Speaker 1>would pump a lot of electricity through the coil, which

0:44:43.760 --> 0:44:46.080
<v Speaker 1>would then create a magnetic field. Because we know about

0:44:46.120 --> 0:44:51.360
<v Speaker 1>the relationship between coils, electricity and the magnets. Magnets, you

0:44:51.440 --> 0:44:54.239
<v Speaker 1>know you can you can either if you run electricity

0:44:54.280 --> 0:44:56.600
<v Speaker 1>through a coil, you'll create a magnetic field. If you

0:44:56.719 --> 0:44:59.680
<v Speaker 1>run a coil through a magnetic field that's alternating or

0:44:59.800 --> 0:45:03.720
<v Speaker 1>that's that's uh, that's changing over time. A dynamic magnetic field,

0:45:04.000 --> 0:45:06.239
<v Speaker 1>you will induce current to flow through the coil. That's

0:45:06.320 --> 0:45:10.759
<v Speaker 1>this relationship between electricity and magnets. Thus the electro magnetism

0:45:11.320 --> 0:45:15.000
<v Speaker 1>that magnetic field will quote reduce the gravitational pull on

0:45:15.040 --> 0:45:17.239
<v Speaker 1>the ring to the point where it floats free end

0:45:17.360 --> 0:45:21.319
<v Speaker 1>quote uh. And that theoretically you could go from Earth

0:45:21.400 --> 0:45:25.200
<v Speaker 1>to Mars in about three hours using this in a

0:45:26.040 --> 0:45:28.560
<v Speaker 1>way that makes no sense to me. I mean, it's

0:45:28.960 --> 0:45:32.560
<v Speaker 1>it's talking about a The math requires that you actually

0:45:32.680 --> 0:45:35.800
<v Speaker 1>have extra dimensions to make it all makes sense. And

0:45:36.200 --> 0:45:38.120
<v Speaker 1>you know, in the in the standard model, we essentially

0:45:38.160 --> 0:45:40.960
<v Speaker 1>think of four dimensions, three in space of one in time.

0:45:41.840 --> 0:45:44.160
<v Speaker 1>But this would require two more dimensions would also end

0:45:44.280 --> 0:45:48.360
<v Speaker 1>up in requiring extra fundamental forces besides the strong and

0:45:48.440 --> 0:45:51.239
<v Speaker 1>weak nuclear force slectro magnetic and gravity that we are

0:45:51.280 --> 0:45:54.120
<v Speaker 1>familiar whe there be two more and uh. And it's

0:45:54.160 --> 0:45:56.400
<v Speaker 1>possible that these things exist, but it's so far it

0:45:56.600 --> 0:46:00.640
<v Speaker 1>exists as far as math goes, and not observation right right,

0:46:01.000 --> 0:46:03.560
<v Speaker 1>even even lower down or even though down and down

0:46:03.600 --> 0:46:05.359
<v Speaker 1>on the scale. There's a few other things that people

0:46:05.400 --> 0:46:07.520
<v Speaker 1>have kind of theorized about when one is called, um,

0:46:08.080 --> 0:46:10.440
<v Speaker 1>this is probably not how you say it all. Qbres

0:46:10.480 --> 0:46:12.959
<v Speaker 1>warp drive is the thing that NASA has talked about

0:46:12.960 --> 0:46:15.200
<v Speaker 1>a little bit, which which kind of kind of is

0:46:15.239 --> 0:46:17.160
<v Speaker 1>similar to the Doppler effect. It says that if you

0:46:17.200 --> 0:46:20.920
<v Speaker 1>can get space time to expand behind you in contract

0:46:21.000 --> 0:46:22.680
<v Speaker 1>in front of you, you can just kind of warp

0:46:22.760 --> 0:46:24.480
<v Speaker 1>straight through it. So, in other words, think of it

0:46:24.600 --> 0:46:27.719
<v Speaker 1>this way. You've gotta like, imagine you have a map

0:46:28.000 --> 0:46:31.200
<v Speaker 1>in front of you, all right, a paper map, and

0:46:31.440 --> 0:46:34.759
<v Speaker 1>you have put a figuring on the leftmost edge of

0:46:34.840 --> 0:46:36.600
<v Speaker 1>the paper map, and your job is to get the

0:46:36.680 --> 0:46:39.440
<v Speaker 1>figuring to the right most edge and the least number

0:46:39.600 --> 0:46:43.120
<v Speaker 1>of die rolls, and there their spaces there that that

0:46:43.920 --> 0:46:47.239
<v Speaker 1>represent how far you can go. So uh, normally there

0:46:47.239 --> 0:46:50.920
<v Speaker 1>would be a hundred spaces between you and the and

0:46:51.080 --> 0:46:53.640
<v Speaker 1>the right side, and you're only able to roll the

0:46:53.800 --> 0:46:56.120
<v Speaker 1>die x number of times, right, But if you can

0:46:56.200 --> 0:46:58.680
<v Speaker 1>just pick up the right if you were able to

0:46:58.800 --> 0:47:01.600
<v Speaker 1>fold the edge of the map app so that it's

0:47:01.760 --> 0:47:04.719
<v Speaker 1>right next to you, and you roll one and you

0:47:04.840 --> 0:47:08.360
<v Speaker 1>move one space and then you unfold the map, you

0:47:08.440 --> 0:47:11.600
<v Speaker 1>have just moved one space, but you've traveled all that distance. Right.

0:47:12.040 --> 0:47:14.800
<v Speaker 1>That's the magic of warp drive. People. We're talking about

0:47:14.960 --> 0:47:19.600
<v Speaker 1>folding all of the galaxy around us to accommodate our

0:47:19.680 --> 0:47:23.400
<v Speaker 1>travel needs. Right, And people say, I'm a demanding traveler.

0:47:24.160 --> 0:47:26.600
<v Speaker 1>But so so that's that's one. You know, it sounds

0:47:26.840 --> 0:47:33.040
<v Speaker 1>super easy on paper. I just explained that. Um, and

0:47:33.520 --> 0:47:37.120
<v Speaker 1>the other being a being creating wormholes. Um, you know,

0:47:37.239 --> 0:47:40.239
<v Speaker 1>you know, a wormhole being kind of a pokey thing through.

0:47:40.400 --> 0:47:43.800
<v Speaker 1>It's shortcut on a paper map. If you if you,

0:47:43.920 --> 0:47:46.120
<v Speaker 1>if you took instead of a little figuring, you had

0:47:46.160 --> 0:47:48.400
<v Speaker 1>a pointy figuring or a pencil or something, and you

0:47:48.480 --> 0:47:50.560
<v Speaker 1>and you stuck that pencil straight through the two points

0:47:50.600 --> 0:47:52.880
<v Speaker 1>in the map that you wanted to travel between, and

0:47:53.000 --> 0:47:55.319
<v Speaker 1>then sort of hit hop kit holes. So there's still

0:47:55.360 --> 0:47:57.920
<v Speaker 1>some travel time, but it's much more reduced. It's this

0:47:58.080 --> 0:48:00.520
<v Speaker 1>is where we get wibbly wobbly timmy wimy right, right.

0:48:00.600 --> 0:48:03.080
<v Speaker 1>But but hypothetically, all we would have to do is

0:48:03.400 --> 0:48:07.880
<v Speaker 1>build two super dense rings a giant super dense rings,

0:48:08.040 --> 0:48:11.000
<v Speaker 1>charge them somehow, and spin them near the speed of light.

0:48:11.160 --> 0:48:13.960
<v Speaker 1>Oh that's easy. Yeah, no problem. So the interesting thing here,

0:48:14.040 --> 0:48:16.720
<v Speaker 1>by the way, is that when we're talking about warping space,

0:48:16.760 --> 0:48:20.400
<v Speaker 1>when we're talking about actually moving or manipulating the space

0:48:20.480 --> 0:48:23.400
<v Speaker 1>time continuum or however you want to fab break of

0:48:23.480 --> 0:48:27.000
<v Speaker 1>space itself, we actually get around the special relativity problem

0:48:27.520 --> 0:48:31.520
<v Speaker 1>because your actual speed doesn't need to be light speed.

0:48:31.560 --> 0:48:34.000
<v Speaker 1>You are just changing the distance. You're not changing you.

0:48:34.160 --> 0:48:36.520
<v Speaker 1>You're not going at this incredible speed. So time is

0:48:36.520 --> 0:48:38.799
<v Speaker 1>still going to travel or stimes. Time is still going

0:48:38.840 --> 0:48:41.800
<v Speaker 1>to pass differently relative to someone on a different ship

0:48:42.000 --> 0:48:45.120
<v Speaker 1>or a different planet, but not at the amazing different

0:48:45.480 --> 0:48:48.120
<v Speaker 1>You wouldn't need an infinite amount of energy to move yourself,

0:48:48.160 --> 0:48:50.759
<v Speaker 1>and you wouldn't have an infinite amount of mass. And

0:48:50.840 --> 0:48:53.439
<v Speaker 1>you also wouldn't find out when you call back home

0:48:53.560 --> 0:48:56.680
<v Speaker 1>that everyone you know is forty years older. Uh, they

0:48:56.760 --> 0:49:00.759
<v Speaker 1>might be, you know, a few micro seconds older than you,

0:49:00.920 --> 0:49:03.520
<v Speaker 1>but it would be so small as to not has

0:49:03.560 --> 0:49:06.560
<v Speaker 1>to be negligible, except for things like communication and stuff

0:49:06.560 --> 0:49:08.680
<v Speaker 1>where you have to have exact timing. Obviously you have

0:49:08.719 --> 0:49:12.160
<v Speaker 1>to have computers to correct those calculations. But when it

0:49:12.239 --> 0:49:14.279
<v Speaker 1>comes to, you know, missing someone's birthday, you don't have

0:49:14.360 --> 0:49:17.760
<v Speaker 1>to worry so much daylight saving time would probably interesting.

0:49:18.600 --> 0:49:21.200
<v Speaker 1>So anyway, Yeah, I mean, there are people who are

0:49:21.239 --> 0:49:23.759
<v Speaker 1>working on these theoretical drives, and it may turn out

0:49:23.840 --> 0:49:27.160
<v Speaker 1>that the theories are just they're they're not truly like

0:49:27.320 --> 0:49:30.480
<v Speaker 1>theories in the sense of h this is really established

0:49:30.520 --> 0:49:34.800
<v Speaker 1>stuff just workingematical theories. More, they're more like hypotheses that

0:49:34.880 --> 0:49:38.200
<v Speaker 1>we have yet to prove um. So it'll be interesting

0:49:38.239 --> 0:49:40.800
<v Speaker 1>to see if we ever do develop anything beyond the

0:49:41.160 --> 0:49:45.799
<v Speaker 1>propulsion systems that we're currently looking into. Uh. I mean,

0:49:46.000 --> 0:49:50.160
<v Speaker 1>it would obviously be very helpful for anything involving colonization

0:49:50.320 --> 0:49:53.279
<v Speaker 1>or exploration, because otherwise it's going to take us a

0:49:53.400 --> 0:49:57.719
<v Speaker 1>really long time. Generations. You you would have to build

0:49:57.719 --> 0:50:01.760
<v Speaker 1>spacecraft capable of supporting multiple generation stions of people aboard

0:50:01.840 --> 0:50:04.600
<v Speaker 1>that with a very limited number of supplies because you know,

0:50:04.640 --> 0:50:07.200
<v Speaker 1>you pretty much you have what you take with you.

0:50:08.040 --> 0:50:10.120
<v Speaker 1>You know, you know, most we don't know of any

0:50:10.200 --> 0:50:14.480
<v Speaker 1>shopping malls out there beyond Earth. You have to have

0:50:14.600 --> 0:50:17.480
<v Speaker 1>to grow out yourself. Ye. So anyway, that that kind

0:50:17.520 --> 0:50:21.480
<v Speaker 1>of wraps up this discussion about star Wars and hyper space.

0:50:21.560 --> 0:50:25.000
<v Speaker 1>The Kessel run, what we're actually looking into as means

0:50:25.040 --> 0:50:28.560
<v Speaker 1>of propulsion in space it's a really interesting topic. I'm

0:50:28.600 --> 0:50:31.920
<v Speaker 1>glad that we we grabbed this one as our first episode.

0:50:32.239 --> 0:50:34.879
<v Speaker 1>And hey, to all my Star Wars fans out there,

0:50:34.920 --> 0:50:38.480
<v Speaker 1>I just have to say, live long and prosper. I

0:50:38.560 --> 0:50:42.520
<v Speaker 1>hope you guys enjoyed this classic episode tech Stuff about hyperspace.

0:50:42.719 --> 0:50:45.440
<v Speaker 1>I think that's a pretty awesome science fiction topic that

0:50:45.560 --> 0:50:48.799
<v Speaker 1>I find particularly fascinating. Don't know if we're ever going

0:50:48.840 --> 0:50:53.319
<v Speaker 1>to see any meaningful manifestation of that idea, or maybe

0:50:53.440 --> 0:50:56.520
<v Speaker 1>we just ultimately you find out that there's no real

0:50:56.640 --> 0:51:00.960
<v Speaker 1>way to achieve that particular flight of fancy. I hope otherwise,

0:51:01.040 --> 0:51:03.520
<v Speaker 1>but we'll see. If you guys have any suggestions for
