WEBVTT - Walls

0:00:03.800 --> 0:00:06.680
<v Speaker 1>Welcome to Stuff to Blow Your Mind from how Stuff

0:00:06.680 --> 0:00:13.840
<v Speaker 1>Works dot Com. Hey, welcome to Stuff to Blow your Mind.

0:00:13.920 --> 0:00:16.639
<v Speaker 1>My name is Robert Lamb and I'm Julie Douglas. In

0:00:16.680 --> 0:00:20.360
<v Speaker 1>this episode, we're talking about walls, which sounds a little big,

0:00:20.960 --> 0:00:23.520
<v Speaker 1>is a big topic because we live in this world

0:00:23.640 --> 0:00:26.800
<v Speaker 1>of walls all around us. We have walls that we've erected,

0:00:27.440 --> 0:00:29.880
<v Speaker 1>walls that are physical walls that are made of stone,

0:00:29.920 --> 0:00:33.400
<v Speaker 1>that are made of wood, walls that are legal walls,

0:00:33.479 --> 0:00:36.000
<v Speaker 1>walls that are mental walls that are from those just

0:00:36.200 --> 0:00:40.200
<v Speaker 1>of ideas, ideas of legacy, ideas of division, hidden walls,

0:00:40.600 --> 0:00:44.360
<v Speaker 1>the walls naked to the eye, firewalls, censorship. With any

0:00:44.360 --> 0:00:47.280
<v Speaker 1>situation with the wall, you have an outsider and you

0:00:47.320 --> 0:00:51.319
<v Speaker 1>have an insider. Generally, when we're contemplating walls, were on

0:00:51.320 --> 0:00:53.040
<v Speaker 1>one side of the other. I guess it's possible to

0:00:53.040 --> 0:00:55.080
<v Speaker 1>stand on the top of the wall, but that's a

0:00:55.560 --> 0:00:59.320
<v Speaker 1>that's a different situation, a precarious position to be in. Yeah, right,

0:00:59.360 --> 0:01:00.720
<v Speaker 1>you don't want to star out of the wall. But

0:01:00.760 --> 0:01:03.640
<v Speaker 1>this is one of the oldest ideas really in human civilization.

0:01:03.680 --> 0:01:07.240
<v Speaker 1>But we've been building physical walls to protect cities and

0:01:07.319 --> 0:01:10.360
<v Speaker 1>towns for ages. Walled cities are one of the earliest

0:01:10.360 --> 0:01:14.040
<v Speaker 1>symbols of civilization. How do you protect a settlement against

0:01:14.160 --> 0:01:18.279
<v Speaker 1>marauders who were using their horses to try and steal

0:01:18.600 --> 0:01:22.640
<v Speaker 1>your agricultural excess? And in fact, the Chinese word for

0:01:22.840 --> 0:01:25.759
<v Speaker 1>city and walls is the same chain, which I found

0:01:25.840 --> 0:01:29.080
<v Speaker 1>is interesting because that's how that's how important walls were

0:01:29.120 --> 0:01:32.560
<v Speaker 1>in the emergence of cities in Chinese history. Yeah, and

0:01:32.560 --> 0:01:35.200
<v Speaker 1>if you guys haven't already figured out, we are seriously

0:01:35.200 --> 0:01:38.920
<v Speaker 1>talking about walls today, like the actual physical structures. One

0:01:38.959 --> 0:01:40.520
<v Speaker 1>of the things that I was thinking about is that

0:01:40.640 --> 0:01:44.679
<v Speaker 1>walls are these concrete abstractions of what I think of

0:01:44.720 --> 0:01:48.720
<v Speaker 1>as maps. Right, This this way to delineate territory, to

0:01:48.880 --> 0:01:51.600
<v Speaker 1>try to say my power base is going to be here.

0:01:52.320 --> 0:01:54.680
<v Speaker 1>And it's kind of like it's a very interesting way

0:01:54.720 --> 0:01:59.360
<v Speaker 1>that we took this abstract notion of ownership and then said, ah,

0:01:59.400 --> 0:02:02.040
<v Speaker 1>we'll show you will put up a wall through our points.

0:02:02.080 --> 0:02:03.520
<v Speaker 1>It's like when you're in your back seat with your

0:02:03.560 --> 0:02:06.000
<v Speaker 1>sister on a long car ride as a kid. You

0:02:06.040 --> 0:02:08.240
<v Speaker 1>each have a side of the back seat that you're

0:02:08.240 --> 0:02:10.400
<v Speaker 1>supposed to stay on, and your stuff is supposed to

0:02:10.440 --> 0:02:14.040
<v Speaker 1>stay on those sides. But during borders disputes, it becomes

0:02:14.080 --> 0:02:17.040
<v Speaker 1>necessary then to point out exactly where the line is.

0:02:17.280 --> 0:02:20.720
<v Speaker 1>It may become necessary to put some tape down that

0:02:20.800 --> 0:02:24.360
<v Speaker 1>line to market in the physical world, and maybe even

0:02:24.400 --> 0:02:28.240
<v Speaker 1>construct a barrier out of luggage or pillows. Yeah, and

0:02:28.280 --> 0:02:30.920
<v Speaker 1>from time to time, though, one might want to show

0:02:30.960 --> 0:02:35.040
<v Speaker 1>their might by crossing that border and knocking down luggage

0:02:35.160 --> 0:02:38.360
<v Speaker 1>and making a political statement really about how they feel

0:02:38.360 --> 0:02:41.560
<v Speaker 1>about you humming for three hours in the car, right. Yeah,

0:02:41.760 --> 0:02:43.840
<v Speaker 1>And then of course you end up with everything that

0:02:43.960 --> 0:02:47.240
<v Speaker 1>has a symbolic power. In human culture, walls take on

0:02:47.360 --> 0:02:50.679
<v Speaker 1>multiple purposes, and I found this particularly a telling. In

0:02:50.760 --> 0:02:54.720
<v Speaker 1>ancient Chinese tradition, you have the city gods cheng hung,

0:02:55.080 --> 0:02:58.640
<v Speaker 1>who protect the moats and walls of towns, so that

0:02:58.680 --> 0:03:02.280
<v Speaker 1>they're important because they're helping protect your very livelihood. Your

0:03:02.360 --> 0:03:05.600
<v Speaker 1>very life and everything you hold dear is protected by

0:03:05.639 --> 0:03:08.040
<v Speaker 1>these walls and moats, and therefore by the deity that

0:03:08.080 --> 0:03:11.440
<v Speaker 1>attends to them. But the chiang Hung also make sure

0:03:11.480 --> 0:03:13.480
<v Speaker 1>that the king of the dead doesn't take any souls

0:03:13.520 --> 0:03:17.480
<v Speaker 1>away without his permission, And so not only is he

0:03:17.600 --> 0:03:19.959
<v Speaker 1>a lord of walls and moats, he's also a lord

0:03:20.000 --> 0:03:23.400
<v Speaker 1>of death, and I find that's an interesting just symbolic

0:03:23.680 --> 0:03:26.079
<v Speaker 1>economy thing. What I like about this is that this

0:03:26.440 --> 0:03:29.359
<v Speaker 1>city God are these lords of walls and moats, it's

0:03:29.360 --> 0:03:32.760
<v Speaker 1>another name for them. Uh, there's a bit of bureaucracy

0:03:32.800 --> 0:03:35.000
<v Speaker 1>involved with us, and that they're usually considered to be

0:03:35.040 --> 0:03:37.480
<v Speaker 1>the reincarnation of a human being who had been an

0:03:37.520 --> 0:03:41.520
<v Speaker 1>official in earlier times. And the city God was thought

0:03:41.560 --> 0:03:45.400
<v Speaker 1>to change every three years, just like a living magistrate

0:03:45.440 --> 0:03:48.920
<v Speaker 1>would change office every three years. And both the magistrate

0:03:49.000 --> 0:03:53.040
<v Speaker 1>and the gods hold sway over the same administrative area.

0:03:53.680 --> 0:03:57.160
<v Speaker 1>So as you say, you know there's some supernatural areas there,

0:03:57.720 --> 0:04:01.600
<v Speaker 1>but there's this expectation that there's formal reverence paid to

0:04:01.680 --> 0:04:04.240
<v Speaker 1>the city God. So in that you see both Chinese

0:04:04.280 --> 0:04:07.320
<v Speaker 1>efficiency but also this very important notion of venerating your

0:04:07.320 --> 0:04:11.440
<v Speaker 1>ancestors in culture, combined in this idea that that someone

0:04:11.520 --> 0:04:15.000
<v Speaker 1>was dispatching their souls to the underworld realm. Speaking of China,

0:04:15.040 --> 0:04:17.640
<v Speaker 1>this brings us, of course to the Great Wall of China,

0:04:17.720 --> 0:04:19.919
<v Speaker 1>which is when you when you talk about walls, there

0:04:19.960 --> 0:04:22.360
<v Speaker 1>are various examples that come to mind. There's the Whaling Wall,

0:04:22.400 --> 0:04:26.039
<v Speaker 1>there's the Berlin Wall, there's Hadrian's Wall. There are plenty

0:04:26.040 --> 0:04:28.200
<v Speaker 1>of examples, but the big one the main landers of

0:04:28.240 --> 0:04:31.719
<v Speaker 1>the world is the Great Wall of China. And the

0:04:31.800 --> 0:04:34.600
<v Speaker 1>history of the wall is really fascinating because it's easy

0:04:34.640 --> 0:04:36.360
<v Speaker 1>to just sort of you've seen a picture of it.

0:04:36.600 --> 0:04:38.120
<v Speaker 1>You know what it looks like. You know, it's a

0:04:38.680 --> 0:04:41.359
<v Speaker 1>something to see if you're a tourist in China. But

0:04:41.480 --> 0:04:43.719
<v Speaker 1>what is it? What is its history? How is it conceived?

0:04:44.120 --> 0:04:48.719
<v Speaker 1>And the wall dates back more than two thousand years

0:04:48.920 --> 0:04:52.560
<v Speaker 1>to a time of unification in China, and this is

0:04:52.600 --> 0:04:56.520
<v Speaker 1>when you had the Chin dynasty uniting seven warring kingdoms

0:04:56.520 --> 0:04:58.520
<v Speaker 1>that's including itself. And if they do that, they have

0:04:58.560 --> 0:05:01.720
<v Speaker 1>all these separate walls that were built by independent kingdoms,

0:05:01.800 --> 0:05:06.080
<v Speaker 1>and so dynasty be instiling them together. And the idea

0:05:06.120 --> 0:05:10.240
<v Speaker 1>is to protect against marauders, so they can script hundreds

0:05:10.279 --> 0:05:13.480
<v Speaker 1>and thousands of workers. We were talking groups of prisoners,

0:05:13.600 --> 0:05:18.200
<v Speaker 1>political enemies, peasants, soldiers, and they worked for ten years

0:05:18.400 --> 0:05:22.599
<v Speaker 1>on this project. Thousands upon thousands die, as tends to happen,

0:05:22.600 --> 0:05:25.320
<v Speaker 1>and legend has it that the bones of individuals who

0:05:25.360 --> 0:05:28.720
<v Speaker 1>died constructing the wall are then then become a part

0:05:28.800 --> 0:05:30.800
<v Speaker 1>of the wall, making it in some people's words, the

0:05:30.839 --> 0:05:34.000
<v Speaker 1>longest cemetery on earth. Yeah, and much of this is

0:05:34.000 --> 0:05:36.960
<v Speaker 1>because this is happening during the Chin dynasty, right, And

0:05:37.040 --> 0:05:40.120
<v Speaker 1>this is again you talked about the neighboring territories that

0:05:40.160 --> 0:05:43.440
<v Speaker 1>were finally united, these little fiefdoms that had a lot

0:05:43.480 --> 0:05:46.720
<v Speaker 1>of strife, but it was united under what I guess

0:05:46.720 --> 0:05:50.159
<v Speaker 1>you could say was China's first emperor, because China wasn't

0:05:50.200 --> 0:05:53.039
<v Speaker 1>China until this. This guy united them. And when I

0:05:53.040 --> 0:05:56.000
<v Speaker 1>say guy, I mean thirteen year old, and this thirteen

0:05:56.040 --> 0:05:59.600
<v Speaker 1>year old is Chin Chow Wong d He is I

0:05:59.640 --> 0:06:02.479
<v Speaker 1>guess you could say a bit of a megalomaniac. He

0:06:02.640 --> 0:06:06.560
<v Speaker 1>begins to actually think about this unification and becomes obsessed

0:06:07.120 --> 0:06:12.320
<v Speaker 1>with this idea that demons in these barbarians are going

0:06:12.360 --> 0:06:16.159
<v Speaker 1>to take over China. And so that's where he mandates

0:06:16.200 --> 0:06:19.559
<v Speaker 1>this length of the wall to be constructed. And again

0:06:19.600 --> 0:06:22.800
<v Speaker 1>there are bits of construction of these walls throughout these

0:06:22.839 --> 0:06:25.200
<v Speaker 1>thousands of years. But this is the guy who decides

0:06:25.279 --> 0:06:28.080
<v Speaker 1>that it's really important to have from the Gobi Desert

0:06:28.120 --> 0:06:31.800
<v Speaker 1>to the Yellow Sea this fortress. Yes, it's fascinating the

0:06:31.839 --> 0:06:35.920
<v Speaker 1>idea that the wall is protecting not only against actual barbarians,

0:06:35.920 --> 0:06:38.600
<v Speaker 1>but also against demons, so that it's not just a

0:06:38.839 --> 0:06:42.880
<v Speaker 1>military barrier, it's a it's a spiritual barrier as well. Again,

0:06:43.000 --> 0:06:44.679
<v Speaker 1>keep in mind with all if this is two thousand

0:06:44.760 --> 0:06:48.800
<v Speaker 1>years ago, so this is a time when spiritualism, megalomania

0:06:48.920 --> 0:06:52.800
<v Speaker 1>and abuse of the peasantry we're pretty much in vogue everywhere.

0:06:53.000 --> 0:06:55.640
<v Speaker 1>So so this is, you know, not unique to China

0:06:55.680 --> 0:06:58.880
<v Speaker 1>by any aspect of the imagination, but the idea that

0:06:58.880 --> 0:07:02.640
<v Speaker 1>that you're you're protecting against not only things, but against ideas.

0:07:03.120 --> 0:07:05.480
<v Speaker 1>I think he's very telling because we see the symbolic

0:07:05.520 --> 0:07:07.960
<v Speaker 1>power of the wall rather overtly, as we'll see in

0:07:08.040 --> 0:07:10.200
<v Speaker 1>various examples of walls. We look at here too, when

0:07:10.280 --> 0:07:13.160
<v Speaker 1>when humans build walls, they're almost always thinking of that

0:07:13.280 --> 0:07:16.520
<v Speaker 1>symbolic power as well, not only to the outsider, and

0:07:16.560 --> 0:07:18.880
<v Speaker 1>to the outside or the wall is a clear statement

0:07:18.920 --> 0:07:21.320
<v Speaker 1>of hey, you're not welcome here. You stay on your

0:07:21.360 --> 0:07:23.400
<v Speaker 1>side of the back seat and I'll stay on mine.

0:07:23.840 --> 0:07:26.880
<v Speaker 1>And then to the insider, the wall says I have

0:07:26.920 --> 0:07:30.160
<v Speaker 1>built you a wall. You were protected, you were safe,

0:07:30.360 --> 0:07:32.800
<v Speaker 1>you know. It is saying there is a physical barrier

0:07:32.880 --> 0:07:36.000
<v Speaker 1>between you and the things that you were afraid of.

0:07:36.480 --> 0:07:38.560
<v Speaker 1>And you can thank me for it. Well, I mean, yeah,

0:07:38.560 --> 0:07:41.880
<v Speaker 1>it's very much like the Boogeyman, right. And to this point,

0:07:42.600 --> 0:07:46.480
<v Speaker 1>this emperor decided that he wanted the circuitous wall built

0:07:46.560 --> 0:07:49.200
<v Speaker 1>and not a straight path. And the reason is because

0:07:49.240 --> 0:07:52.960
<v Speaker 1>a straight line, in demonology is great for demons because

0:07:52.960 --> 0:07:56.000
<v Speaker 1>they're able to navigate only on straight lines and not

0:07:56.120 --> 0:07:58.840
<v Speaker 1>on curves. So he's gonna make it even more difficult

0:07:58.840 --> 0:08:02.960
<v Speaker 1>for these demons by making this this serpentine wall that's

0:08:03.000 --> 0:08:04.920
<v Speaker 1>twenty four ft high. And certainly that's one of the

0:08:04.960 --> 0:08:08.080
<v Speaker 1>things that's amazing about. Examples of the wall today and again,

0:08:08.120 --> 0:08:10.840
<v Speaker 1>examples of the wall today, as we'll discuss fees are

0:08:11.240 --> 0:08:13.960
<v Speaker 1>the wall has been added to and renovated numerous times

0:08:13.960 --> 0:08:16.320
<v Speaker 1>throughout history, so we're not necessarily talking about the same

0:08:16.400 --> 0:08:19.480
<v Speaker 1>physical wall in the same bricks. But you still see

0:08:19.520 --> 0:08:22.400
<v Speaker 1>that shape. It's like a serpent lying across the hills. Yeah,

0:08:22.440 --> 0:08:23.960
<v Speaker 1>and it is fascinating because it's one of those things

0:08:24.000 --> 0:08:27.160
<v Speaker 1>that people had long assumed was one big, coherent, linked

0:08:27.240 --> 0:08:29.360
<v Speaker 1>up wall, but in fact it's not. That was one

0:08:29.400 --> 0:08:31.920
<v Speaker 1>of the myths. Another myth is that you could see

0:08:32.080 --> 0:08:35.080
<v Speaker 1>this from the moon. Yeah, I see it from space

0:08:35.120 --> 0:08:37.240
<v Speaker 1>and it's it's just not so no, it's not so

0:08:37.360 --> 0:08:40.640
<v Speaker 1>lovely story, but it is lovely. But to go back

0:08:40.679 --> 0:08:43.480
<v Speaker 1>to this emperor and talk a little bit about Chinchu

0:08:43.559 --> 0:08:47.680
<v Speaker 1>Woandi and how he treated peasants. You refer to this

0:08:47.760 --> 0:08:49.880
<v Speaker 1>as the world's longest cemetery. At least some people have

0:08:49.920 --> 0:08:52.760
<v Speaker 1>talked about this the Great Wall of China being this Again,

0:08:52.840 --> 0:08:56.720
<v Speaker 1>he's sort of indulged in soothsaying and a little bit

0:08:56.760 --> 0:09:00.439
<v Speaker 1>of paranoia, and it is said that his sus sooth

0:09:00.600 --> 0:09:04.439
<v Speaker 1>sayer told him that the wall would actually never be built,

0:09:04.480 --> 0:09:07.480
<v Speaker 1>which he was mortally frightened of right, because the barbarians

0:09:07.520 --> 0:09:09.800
<v Speaker 1>were gonna come get him in the demons unless ten

0:09:09.880 --> 0:09:13.640
<v Speaker 1>thousand men were entombed in the wall. Wow, what what

0:09:13.800 --> 0:09:16.000
<v Speaker 1>sus can you imagine being that guy being on the

0:09:16.160 --> 0:09:18.520
<v Speaker 1>payroll that takes a lot of comments really to you, like,

0:09:18.559 --> 0:09:21.040
<v Speaker 1>you know, this is the message ten thousand You gotta

0:09:21.120 --> 0:09:24.400
<v Speaker 1>you gotta execute them, throw them in there. So Shinchu

0:09:24.480 --> 0:09:27.360
<v Speaker 1>Wonghdi decides, you know what, he's the ruler. He realizes

0:09:27.440 --> 0:09:30.280
<v Speaker 1>that he full well can't just spare that many men,

0:09:30.960 --> 0:09:33.280
<v Speaker 1>So he finds a loophole in the form of one

0:09:33.320 --> 0:09:36.000
<v Speaker 1>guy who has the word or the character for ten

0:09:36.080 --> 0:09:38.960
<v Speaker 1>thousand in his name. I guess what his fate is.

0:09:39.440 --> 0:09:42.199
<v Speaker 1>He is killed and burying the wall. Yeah, he's tossed

0:09:42.200 --> 0:09:45.640
<v Speaker 1>into the wall. But again there's this idea that this

0:09:45.679 --> 0:09:50.920
<v Speaker 1>wall begins to take on meaning of forced labor, being subjugated.

0:09:51.440 --> 0:09:54.400
<v Speaker 1>As you can start to see, peasants are not really

0:09:54.520 --> 0:09:57.319
<v Speaker 1>digging this wall right. The symbolic power to the insider

0:09:57.679 --> 0:10:00.000
<v Speaker 1>is not just an idea of protection, but an idea

0:10:00.040 --> 0:10:03.080
<v Speaker 1>of This is the kind of thing that governments and

0:10:03.240 --> 0:10:07.000
<v Speaker 1>rulers create out of your blood. Right. It becomes a

0:10:07.040 --> 0:10:10.160
<v Speaker 1>symbol of oppression and actually is very much a symbol

0:10:10.160 --> 0:10:12.560
<v Speaker 1>of that for a long time until we get to

0:10:12.679 --> 0:10:14.600
<v Speaker 1>the twentieth century. And we'll talk about that in a moment.

0:10:14.720 --> 0:10:17.840
<v Speaker 1>But let's talk about this as being an imperfect barrier.

0:10:18.000 --> 0:10:20.560
<v Speaker 1>That's the thing. Obviously the wall is important, like we said,

0:10:20.640 --> 0:10:23.040
<v Speaker 1>is an idea of protection, but does it actually offer

0:10:23.120 --> 0:10:27.000
<v Speaker 1>protection On one level, you're building these walls often at

0:10:27.040 --> 0:10:29.480
<v Speaker 1>the on the extremes there on the frontier there between

0:10:30.280 --> 0:10:34.439
<v Speaker 1>civilization and the barbarians and the demons, so you're having

0:10:34.520 --> 0:10:37.439
<v Speaker 1>to basically establish colonies there. I mean, think of it

0:10:37.679 --> 0:10:39.800
<v Speaker 1>in almost in terms of like an off world colony

0:10:39.880 --> 0:10:42.240
<v Speaker 1>kind of a situation. You're having to have soldiers there

0:10:42.320 --> 0:10:45.719
<v Speaker 1>that are also growing their own food, and there are

0:10:45.800 --> 0:10:49.000
<v Speaker 1>more a part of the frontier than they are of

0:10:49.040 --> 0:10:52.480
<v Speaker 1>the homeland, so they actually end up having some sort

0:10:52.520 --> 0:10:56.439
<v Speaker 1>of rapport with the local populations with the barbarians, and

0:10:56.480 --> 0:11:00.800
<v Speaker 1>as such are susceptible to bribes. Just here's there are

0:11:00.840 --> 0:11:02.280
<v Speaker 1>a few bucks, look the other way up while we

0:11:02.320 --> 0:11:04.600
<v Speaker 1>march an army through and join our army or join

0:11:04.640 --> 0:11:07.640
<v Speaker 1>our army, then that happens as well, So it becomes

0:11:07.720 --> 0:11:10.960
<v Speaker 1>very difficult just to to man and protect it. And

0:11:10.960 --> 0:11:13.400
<v Speaker 1>then you're gonna have gaps as well. For instance, just

0:11:13.440 --> 0:11:15.320
<v Speaker 1>in terms of the wall itself, the wall is not

0:11:15.760 --> 0:11:16.959
<v Speaker 1>you might think of the wall as being in this

0:11:17.120 --> 0:11:20.520
<v Speaker 1>NonStop wall that actually sneaks across the entire country, But

0:11:20.559 --> 0:11:22.719
<v Speaker 1>there are gaps in it, and there are places where

0:11:22.720 --> 0:11:25.760
<v Speaker 1>just natural barriers are depended on to to serve as

0:11:25.800 --> 0:11:28.320
<v Speaker 1>the wall well, and it has been maintained, so there

0:11:28.320 --> 0:11:30.760
<v Speaker 1>are there are parts of it that are in ruins.

0:11:31.480 --> 0:11:34.800
<v Speaker 1>So you have Genghis Khan or Genghis Khan is he

0:11:34.960 --> 0:11:38.760
<v Speaker 1>some country for two k the big g K he

0:11:38.840 --> 0:11:42.320
<v Speaker 1>brings with him a huge army and martial arts and

0:11:43.600 --> 0:11:48.760
<v Speaker 1>a flair for psychological terror, and he reaches the wall. Right,

0:11:48.960 --> 0:11:52.200
<v Speaker 1>and for a good hundred years, the rule of China

0:11:52.400 --> 0:11:54.960
<v Speaker 1>comes under Mongol. Yeah, they were the ones in charge

0:11:55.000 --> 0:11:58.240
<v Speaker 1>when Marco Polo visited. That's right, that's right, And so

0:11:58.440 --> 0:12:02.000
<v Speaker 1>Mongols are really taking over. But then in thirteen sixty eight,

0:12:02.000 --> 0:12:05.040
<v Speaker 1>a Chinese peasant leads a rebellion against Mongol rule and

0:12:05.040 --> 0:12:07.520
<v Speaker 1>this helps to establish the Ming dynasty. I only mention

0:12:07.559 --> 0:12:10.280
<v Speaker 1>this because the Ming dynasty is really important and actually

0:12:10.840 --> 0:12:13.760
<v Speaker 1>giving a lot of shoring up to the wall. Yeah,

0:12:13.800 --> 0:12:17.400
<v Speaker 1>this was thirteen sixty eight, and the Ming dynasty looks

0:12:17.400 --> 0:12:19.040
<v Speaker 1>at the wall and says, you know, this is something

0:12:19.080 --> 0:12:20.679
<v Speaker 1>we need to fix up. You need to get it

0:12:20.720 --> 0:12:22.160
<v Speaker 1>going because we don't want to be conquered by the

0:12:22.160 --> 0:12:26.080
<v Speaker 1>barbarians again. Right, And with it, they actually are responsible

0:12:26.160 --> 0:12:30.480
<v Speaker 1>for architectural embellishments on it and beginning to document various

0:12:30.480 --> 0:12:32.959
<v Speaker 1>points in history. So you really begin to see more

0:12:32.960 --> 0:12:36.760
<v Speaker 1>of a coherent picture of the Wall with the Ming dynasty.

0:12:36.800 --> 0:12:39.960
<v Speaker 1>But then here's another thing that happens under man Chew rule.

0:12:40.080 --> 0:12:42.360
<v Speaker 1>The wall no longer matters since the land on both

0:12:42.360 --> 0:12:45.079
<v Speaker 1>sides just ruled by Man Chew. When China is invaded

0:12:45.120 --> 0:12:47.920
<v Speaker 1>yet again. Yeah, this is seventeen hundreds, the Manchew invade

0:12:48.040 --> 0:12:50.160
<v Speaker 1>the Ming dynasty. The Man a number of changes to it,

0:12:50.240 --> 0:12:52.840
<v Speaker 1>added to its length, to its width, double and triple

0:12:52.880 --> 0:12:55.480
<v Speaker 1>walls in some places to really reinforce it. But then

0:12:55.520 --> 0:12:58.560
<v Speaker 1>when the Man Chow's invade in seventeen hundreds, it's largely

0:12:58.600 --> 0:13:01.720
<v Speaker 1>abandoned as a military power. It kind of stays that

0:13:01.760 --> 0:13:04.680
<v Speaker 1>way for a while, pretty much the until very recent times.

0:13:05.120 --> 0:13:09.559
<v Speaker 1>During that time, the wall crumbles, the wall is looted

0:13:09.600 --> 0:13:12.280
<v Speaker 1>for building supplies because you have all of these stones

0:13:12.400 --> 0:13:15.240
<v Speaker 1>right there are ready to use, and so people carry

0:13:15.240 --> 0:13:17.680
<v Speaker 1>it off to build things that are of actual value

0:13:17.720 --> 0:13:20.319
<v Speaker 1>to their lives because the walls just sitting there, it's

0:13:20.360 --> 0:13:23.559
<v Speaker 1>not even a military factor anymore. And then when Mauston

0:13:23.800 --> 0:13:26.240
<v Speaker 1>comes to power, he encourages Chinese people to use this,

0:13:26.760 --> 0:13:28.480
<v Speaker 1>to use the bricks, to use parts of the wall

0:13:28.520 --> 0:13:32.079
<v Speaker 1>to build things, and now brings in also this idea

0:13:32.240 --> 0:13:35.160
<v Speaker 1>of the modern you know, part of the cultural revolution,

0:13:35.440 --> 0:13:38.120
<v Speaker 1>cultural revolution, and a huge part of it is we're

0:13:38.120 --> 0:13:40.600
<v Speaker 1>going to focus on the modern China and the future China. Yeah,

0:13:40.640 --> 0:13:42.760
<v Speaker 1>we're going to obliterate the past. Right, the wall is

0:13:42.880 --> 0:13:45.360
<v Speaker 1>very much a piece of the past, and a piece

0:13:45.360 --> 0:13:47.800
<v Speaker 1>of the past that has still leaves a bad taste

0:13:47.840 --> 0:13:49.600
<v Speaker 1>in a lot of people's lives because it is this

0:13:49.720 --> 0:13:52.040
<v Speaker 1>thing build out of their blood. It is this symbol

0:13:52.400 --> 0:13:56.520
<v Speaker 1>of the domineering, violent rule. Yeah, it's not the one

0:13:56.520 --> 0:13:58.280
<v Speaker 1>of the wonders of the world that we now think

0:13:58.320 --> 0:14:01.439
<v Speaker 1>of it. But this it begins to to recast itself

0:14:01.559 --> 0:14:05.880
<v Speaker 1>in modern times. Right around nineteen four, there's this idea

0:14:06.200 --> 0:14:09.480
<v Speaker 1>that the wall begins to take on national pride, and

0:14:09.520 --> 0:14:11.880
<v Speaker 1>they actually say, let us love our country and restore

0:14:11.880 --> 0:14:14.880
<v Speaker 1>our great Wall. This becomes a big mission for them. Yeah,

0:14:14.920 --> 0:14:17.720
<v Speaker 1>you have important foreign heads of state visit. Reagan visits,

0:14:17.720 --> 0:14:20.040
<v Speaker 1>Scorba Chop visits where they go to the Great Wall.

0:14:20.480 --> 0:14:23.520
<v Speaker 1>Nixon visits. You know, and as I say, Nixon, who

0:14:23.720 --> 0:14:25.680
<v Speaker 1>wasn't he the person who said something like only a

0:14:25.720 --> 0:14:28.800
<v Speaker 1>great people could build this great wall, which starts to

0:14:29.560 --> 0:14:32.840
<v Speaker 1>even then recast its image. Yeah. Luckily he was a

0:14:32.840 --> 0:14:36.200
<v Speaker 1>wall enthusiast. He was all about putting Floyd but this

0:14:36.320 --> 0:14:38.440
<v Speaker 1>wall is in general. So yes, he added to that

0:14:38.600 --> 0:14:41.400
<v Speaker 1>vibe that this was something that was important and worth celebrating.

0:14:41.760 --> 0:14:44.520
<v Speaker 1>And so over the last few decades you see this

0:14:44.600 --> 0:14:49.360
<v Speaker 1>increasing restoration of portions of the wall, increased commercialization of

0:14:49.400 --> 0:14:52.280
<v Speaker 1>portions of the Wall. I'm treating. In the Lonely Planet

0:14:52.560 --> 0:14:54.640
<v Speaker 1>China Guide, they point out that there are sections of

0:14:54.640 --> 0:14:58.320
<v Speaker 1>the Wall that are just insanely populated. Really, I mean,

0:14:58.360 --> 0:15:00.920
<v Speaker 1>you just have tourists there almost all the time unless

0:15:00.920 --> 0:15:03.440
<v Speaker 1>you go in the dead of winter. Their gift shops,

0:15:03.480 --> 0:15:05.440
<v Speaker 1>their tourists, there are people selling things, and I mean

0:15:05.480 --> 0:15:08.280
<v Speaker 1>that's just the way it goes with popular locations. But

0:15:08.320 --> 0:15:10.520
<v Speaker 1>there are still plenty of portions of the Wall that

0:15:10.600 --> 0:15:14.680
<v Speaker 1>are not super innovated, that are still beautiful and don't

0:15:14.720 --> 0:15:17.840
<v Speaker 1>have like a restaurant in them. Not that their portions

0:15:17.800 --> 0:15:19.640
<v Speaker 1>of the restaurants of them, but you know what I'm saying,

0:15:19.680 --> 0:15:21.840
<v Speaker 1>don't have as in them. Yeah, there are places in

0:15:21.920 --> 0:15:23.400
<v Speaker 1>China where you can go if you look into it

0:15:23.400 --> 0:15:25.240
<v Speaker 1>and you do the research, where you can get more

0:15:25.280 --> 0:15:28.360
<v Speaker 1>of a serene views the wall as opposed to a

0:15:28.480 --> 0:15:32.080
<v Speaker 1>hyper commercialized version. But it's it's still it's even if

0:15:32.080 --> 0:15:33.560
<v Speaker 1>you go to those areas where there are a lot

0:15:33.560 --> 0:15:36.360
<v Speaker 1>of people and there's a lot of commercialization, it's still

0:15:36.400 --> 0:15:38.600
<v Speaker 1>a stunning site. Indeed. All right, we're gonna take a

0:15:38.680 --> 0:15:40.120
<v Speaker 1>quick break, and when we come back, we're going to

0:15:40.240 --> 0:15:42.680
<v Speaker 1>move beyond the Great Wall of China and discuss some

0:15:42.760 --> 0:15:47.320
<v Speaker 1>more modern examples of walls in our lives, including cosmic walls.

0:15:51.560 --> 0:15:54.520
<v Speaker 1>All right, we're back. So when you think beyond the

0:15:54.520 --> 0:15:56.240
<v Speaker 1>Great Wall of China and you think of modern walls,

0:15:56.280 --> 0:15:58.080
<v Speaker 1>what comes to mind? Okay, Well, I mean, you know,

0:15:58.240 --> 0:16:00.280
<v Speaker 1>I think about Berlin Wall. I also think about the

0:16:00.320 --> 0:16:03.680
<v Speaker 1>Atlantic Wall that Hitler was. I think it's like eight

0:16:03.760 --> 0:16:08.360
<v Speaker 1>hundred miles of sea coast, at least in France that

0:16:08.440 --> 0:16:11.440
<v Speaker 1>he had been constructing as a barrier of and and

0:16:11.640 --> 0:16:14.160
<v Speaker 1>a bit of military might. Yeah, the stuff from saving

0:16:14.160 --> 0:16:18.360
<v Speaker 1>brabt Ryan of remember that. Yeah. But of course, here

0:16:18.440 --> 0:16:22.000
<v Speaker 1>in the US, one of the most strikingly obvious walls

0:16:22.280 --> 0:16:25.760
<v Speaker 1>is more like a fence. The US Mexico border. Well

0:16:25.800 --> 0:16:27.480
<v Speaker 1>we call it offense, but it sure as heck looks

0:16:27.480 --> 0:16:31.200
<v Speaker 1>like a wall in many areas. And it's been in

0:16:31.240 --> 0:16:33.920
<v Speaker 1>the news a lot, especially with the conservative primaries leading

0:16:34.000 --> 0:16:36.720
<v Speaker 1>up to this year's presidential election. You've had a lot

0:16:36.720 --> 0:16:38.320
<v Speaker 1>of people touched on this as a hot is a

0:16:38.320 --> 0:16:40.640
<v Speaker 1>hot topic issue immigration in the United States. A lot

0:16:40.680 --> 0:16:42.560
<v Speaker 1>of our listeners are US based, but a lot of

0:16:42.560 --> 0:16:46.280
<v Speaker 1>you are based in other countries. US Mexican migrations are

0:16:46.560 --> 0:16:49.720
<v Speaker 1>very much on voters minds, especially conservative voters. So you

0:16:49.760 --> 0:16:52.160
<v Speaker 1>have people like Herman Kane, the pizza mogul, who came

0:16:52.200 --> 0:16:54.640
<v Speaker 1>out and said we're going to build an electric fence

0:16:54.720 --> 0:16:57.400
<v Speaker 1>made out of pizza, not made out of pizza. He

0:16:57.440 --> 0:17:00.640
<v Speaker 1>did not rule out alligators, as I remember, so moats

0:17:00.640 --> 0:17:03.440
<v Speaker 1>and walls, and then there were some other half cocked

0:17:03.440 --> 0:17:05.840
<v Speaker 1>ideas that were thrown around by some other candidates, but

0:17:05.920 --> 0:17:07.919
<v Speaker 1>it all comes down to this idea of the wall

0:17:08.000 --> 0:17:11.760
<v Speaker 1>right sending this message to Mexico, saying Mexicans are not

0:17:11.840 --> 0:17:14.840
<v Speaker 1>wanted here, and sending more importantly really, because these are

0:17:14.840 --> 0:17:19.200
<v Speaker 1>politicians talking about wall building, sending this message to their

0:17:19.240 --> 0:17:22.480
<v Speaker 1>constituents in the US to say we care about what

0:17:22.520 --> 0:17:25.400
<v Speaker 1>you care about so much that we built this thing.

0:17:25.560 --> 0:17:28.520
<v Speaker 1>We're going to erect this giant symbol of what we're

0:17:28.520 --> 0:17:31.600
<v Speaker 1>talking about, even though their YouTube videos of people scaling

0:17:31.680 --> 0:17:34.200
<v Speaker 1>up these things up and over them in seconds, and

0:17:34.200 --> 0:17:36.680
<v Speaker 1>and it's the same situations coming to play that came

0:17:36.680 --> 0:17:38.960
<v Speaker 1>into play with the Great Wall of China. They're gonna

0:17:38.960 --> 0:17:41.600
<v Speaker 1>be gaps. They're gonna be places where care of the

0:17:41.640 --> 0:17:44.760
<v Speaker 1>border is either less maintained or or it is not

0:17:44.840 --> 0:17:47.760
<v Speaker 1>maintained at all. Well, here's the thing. Last year was

0:17:47.800 --> 0:17:52.159
<v Speaker 1>the biggest sustained drop in immigration from Mexico to the

0:17:52.200 --> 0:17:55.120
<v Speaker 1>United States, leave to be surpassed and scale only by

0:17:55.160 --> 0:17:58.879
<v Speaker 1>losses in the Mexican born US population during the Great Depression.

0:17:59.680 --> 0:18:03.159
<v Speaker 1>So we're actually seeing a drop in immigration to the

0:18:03.240 --> 0:18:08.480
<v Speaker 1>United States from Mexico. And much of this is because well,

0:18:08.520 --> 0:18:11.920
<v Speaker 1>first of all, the Mexican cartel are are acting as

0:18:11.920 --> 0:18:15.280
<v Speaker 1>border agents on the Mexican border, and they're demanding money,

0:18:15.280 --> 0:18:17.760
<v Speaker 1>and sometimes they actually use immigrants as drug mules, so

0:18:17.800 --> 0:18:21.000
<v Speaker 1>it's become far more dangerous as if it weren't already

0:18:21.280 --> 0:18:23.639
<v Speaker 1>to try to cross. But also um on the U.

0:18:23.760 --> 0:18:27.439
<v Speaker 1>S side, it's become much more difficult and rigorous in

0:18:27.560 --> 0:18:30.879
<v Speaker 1>terms of trying to prosecute people for for doing this.

0:18:31.119 --> 0:18:33.240
<v Speaker 1>But of course there's been an economic downturn as well,

0:18:33.440 --> 0:18:36.800
<v Speaker 1>and also you can factor and changes in legislation in

0:18:36.840 --> 0:18:39.520
<v Speaker 1>some of the southern states that have cracked down on

0:18:39.560 --> 0:18:43.440
<v Speaker 1>the use of migrant labor. Right, Yeah, So it is

0:18:43.480 --> 0:18:45.680
<v Speaker 1>one of those things that we wanted to point out

0:18:45.720 --> 0:18:49.400
<v Speaker 1>because it is a huge symbolic effort by the United States,

0:18:49.600 --> 0:18:53.399
<v Speaker 1>but in terms of efficacy and really getting at the

0:18:53.800 --> 0:18:56.560
<v Speaker 1>what they think, or what the United States politicians think

0:18:56.800 --> 0:18:59.760
<v Speaker 1>is the root problem doesn't isn't really solved by this

0:19:00.720 --> 0:19:03.479
<v Speaker 1>right and and those some people may have giggled at

0:19:03.480 --> 0:19:05.760
<v Speaker 1>the idea of building a wall to keep demons at bay.

0:19:05.960 --> 0:19:08.280
<v Speaker 1>Like I said, that is just an avert statement of

0:19:08.440 --> 0:19:11.000
<v Speaker 1>what all walls ultimately symbolized, Like even this wall is

0:19:11.040 --> 0:19:14.280
<v Speaker 1>about keeping demons of the mind at bay. To some

0:19:14.320 --> 0:19:16.679
<v Speaker 1>people on the inside, it is a demonization of the

0:19:16.800 --> 0:19:19.560
<v Speaker 1>threats that in a simple vocation of the threats that

0:19:19.640 --> 0:19:22.280
<v Speaker 1>that lie outside and are waiting to get in. It's

0:19:22.280 --> 0:19:25.280
<v Speaker 1>also worth noting, though, that when you build walls or

0:19:25.359 --> 0:19:28.600
<v Speaker 1>fences of this nature, you're building them in environments that

0:19:28.680 --> 0:19:32.600
<v Speaker 1>did not previously have barriers, So you're you're going to

0:19:32.640 --> 0:19:35.560
<v Speaker 1>cut into not only the migration of people, but the

0:19:35.600 --> 0:19:38.119
<v Speaker 1>migration of animals. So there have been a number of

0:19:38.160 --> 0:19:41.199
<v Speaker 1>studies that have looked into what effects order fences on

0:19:41.240 --> 0:19:44.240
<v Speaker 1>the US Mexican border have had on migrating animals, and

0:19:44.280 --> 0:19:45.919
<v Speaker 1>it doesn't paint a pretty picture, you know, I mean,

0:19:45.960 --> 0:19:49.600
<v Speaker 1>you're altering the psychic and the geographical landscape, right. Yeah,

0:19:49.880 --> 0:19:51.919
<v Speaker 1>And it's interestingly mentioned the psychic because that was one

0:19:51.920 --> 0:19:53.560
<v Speaker 1>of the things that has also been brought up about

0:19:53.560 --> 0:19:56.560
<v Speaker 1>the Great Wall of China and throughout China's history, that

0:19:56.640 --> 0:19:58.800
<v Speaker 1>there were people who thought of it as a disruptor

0:19:59.240 --> 0:20:02.359
<v Speaker 1>of g You know, this is disrupt disrupting the earth energies.

0:20:02.359 --> 0:20:06.120
<v Speaker 1>You're building this unnatural thing that breaks up natural flows

0:20:06.280 --> 0:20:08.480
<v Speaker 1>in the environment. Of course, we raise the walls not

0:20:08.600 --> 0:20:13.239
<v Speaker 1>only against human and imagined threats, we also raised them

0:20:13.240 --> 0:20:17.959
<v Speaker 1>against mother nature. In Japan, the sea walls because as

0:20:18.000 --> 0:20:20.960
<v Speaker 1>an island nation and given its past history with threats

0:20:20.960 --> 0:20:22.919
<v Speaker 1>from the sea, you want to be able to mitigate

0:20:22.960 --> 0:20:25.800
<v Speaker 1>that to some degree. Nearly half of the twenty two

0:20:25.840 --> 0:20:30.320
<v Speaker 1>thousand mile coast in Japan actually has concrete sea walls,

0:20:31.080 --> 0:20:33.400
<v Speaker 1>which would make sense, right because I mean that there's

0:20:33.400 --> 0:20:36.800
<v Speaker 1>a lot of earthquake activity in that area and you

0:20:36.800 --> 0:20:39.119
<v Speaker 1>would want to have some sort of structure try to

0:20:39.200 --> 0:20:42.880
<v Speaker 1>protect you from really high waves. So there's something very

0:20:42.920 --> 0:20:45.879
<v Speaker 1>practical about it. But some people, the opponents of it,

0:20:45.960 --> 0:20:49.120
<v Speaker 1>say that it's not necessarily that effective, and in fact

0:20:49.200 --> 0:20:53.000
<v Speaker 1>we saw that with a tsunami. They are fascinating constructions though,

0:20:53.080 --> 0:20:55.320
<v Speaker 1>that well worth doing a Google image search on because

0:20:55.600 --> 0:20:57.159
<v Speaker 1>if you've never seen when, you may imagine just a

0:20:57.240 --> 0:20:59.520
<v Speaker 1>straight up wall, but there are a lot different because

0:20:59.560 --> 0:21:01.800
<v Speaker 1>stopping of flow, a massive flow of water, is different

0:21:01.800 --> 0:21:05.040
<v Speaker 1>than stopping some marauders on horseback. It's not just about

0:21:05.080 --> 0:21:08.040
<v Speaker 1>putting up the straight barrier, but putting up a structure

0:21:08.119 --> 0:21:12.000
<v Speaker 1>that will slow and halt this approach of water. And

0:21:12.040 --> 0:21:14.480
<v Speaker 1>that's what proponents say. They say, Okay, well, maybe it

0:21:14.520 --> 0:21:18.320
<v Speaker 1>didn't safeguard us against the nuclear reactors, right seawater got

0:21:18.359 --> 0:21:20.640
<v Speaker 1>in there. The wall wasn't actually high enough. It should

0:21:20.680 --> 0:21:23.840
<v Speaker 1>have been built much higher, but it did slow down

0:21:24.200 --> 0:21:28.359
<v Speaker 1>the encroachment of those waves. Sometimes, you know, it gave

0:21:28.400 --> 0:21:31.160
<v Speaker 1>people a couple of extra minutes to try to evacuate,

0:21:31.200 --> 0:21:33.640
<v Speaker 1>which is, you know, the difference between life and death.

0:21:33.760 --> 0:21:35.439
<v Speaker 1>And another example of walls that comes to mind if

0:21:35.480 --> 0:21:37.560
<v Speaker 1>you think back to our episode on the black Blizzards

0:21:37.600 --> 0:21:40.440
<v Speaker 1>of the of the Great Depression of the dust Bowl,

0:21:41.240 --> 0:21:43.959
<v Speaker 1>we mentioned the green walls that you see popping up

0:21:43.960 --> 0:21:47.720
<v Speaker 1>in some portions on green wall projects in China in Africa,

0:21:48.160 --> 0:21:51.320
<v Speaker 1>and the idea here is building a wall against desertification,

0:21:51.520 --> 0:21:55.679
<v Speaker 1>building a wall that will try to prevent the desert

0:21:55.720 --> 0:21:59.119
<v Speaker 1>from encroaching on fertile lands. Yeah, there's something called the

0:21:59.200 --> 0:22:01.919
<v Speaker 1>Yellow Dragon. And each spring, the dust from China's northern

0:22:01.920 --> 0:22:05.119
<v Speaker 1>deserts are swept up by the wind and whipped eastward,

0:22:05.160 --> 0:22:07.399
<v Speaker 1>and they blast into Beijing and they blank at the

0:22:07.400 --> 0:22:11.320
<v Speaker 1>city in a huge coat of dust particles. And that

0:22:11.440 --> 0:22:14.840
<v Speaker 1>has actually created a lot of respiratory ailments in the

0:22:14.920 --> 0:22:19.359
<v Speaker 1>dust of also clogged machinery and posted down airports and

0:22:19.400 --> 0:22:22.159
<v Speaker 1>destroys crops. I mean, it's a very serious problem. And

0:22:22.200 --> 0:22:25.439
<v Speaker 1>really we see walls everywhere in the world around us.

0:22:25.440 --> 0:22:28.359
<v Speaker 1>We see walls in our body, cell membranes, our skin

0:22:28.480 --> 0:22:30.560
<v Speaker 1>even is often seen as a wall, even though when

0:22:30.600 --> 0:22:33.560
<v Speaker 1>you actually examine it, we're talking about a porous layer.

0:22:33.720 --> 0:22:35.960
<v Speaker 1>Things move in and out off, there's a lot of traffics.

0:22:35.960 --> 0:22:37.520
<v Speaker 1>It's kind of like the Great Wall of China in

0:22:37.520 --> 0:22:40.919
<v Speaker 1>that regard. It's not not a perfect barrier by any stretch.

0:22:40.960 --> 0:22:43.440
<v Speaker 1>There are gaps, there are ways to negotiate your way

0:22:43.440 --> 0:22:46.760
<v Speaker 1>inside and more like calanders, I suppose. Yeah, yeah, and

0:22:46.800 --> 0:22:48.959
<v Speaker 1>not only when we're looking in our inward, but when

0:22:49.000 --> 0:22:52.080
<v Speaker 1>we're looking outward as well. There's something called the Sloane

0:22:52.160 --> 0:22:56.280
<v Speaker 1>Great Wall. And this is a far distant grouping of

0:22:56.320 --> 0:23:00.199
<v Speaker 1>galaxies that spans over one billion light years. It's longer

0:23:00.280 --> 0:23:03.840
<v Speaker 1>than any quote unquote structure ever measured. And I put

0:23:03.880 --> 0:23:07.040
<v Speaker 1>structure in quotes because it's kind of hard to argue

0:23:07.080 --> 0:23:10.120
<v Speaker 1>this is actually a structure. These are clusters of galaxies,

0:23:10.720 --> 0:23:13.159
<v Speaker 1>so it's more it's no more a structure really than

0:23:13.200 --> 0:23:16.120
<v Speaker 1>a constellation in the sky. It's a structure. But we're

0:23:16.160 --> 0:23:19.399
<v Speaker 1>so fascinated with walls when we define our limits on

0:23:19.560 --> 0:23:22.280
<v Speaker 1>things through the symbol and the language of walls. So

0:23:22.320 --> 0:23:24.960
<v Speaker 1>as we stare out at these distant clusters of galaxies,

0:23:25.160 --> 0:23:28.240
<v Speaker 1>we can't help but think of them in terms of walls. Well,

0:23:28.280 --> 0:23:30.320
<v Speaker 1>and I guess we could say these are sort of

0:23:30.400 --> 0:23:34.480
<v Speaker 1>cosmic webs, right, and they do create borders between things. Yeah,

0:23:34.520 --> 0:23:38.520
<v Speaker 1>there's void beyond them. They're known as phalactic filament, so

0:23:38.680 --> 0:23:40.960
<v Speaker 1>that's not like filaments in a giant light bulb the

0:23:40.960 --> 0:23:43.399
<v Speaker 1>size of the moon or anything. They're actually known to

0:23:43.560 --> 0:23:47.919
<v Speaker 1>span these vast distances and they're lattice like structures. And

0:23:47.920 --> 0:23:50.800
<v Speaker 1>the cool thing about these filaments is that they are

0:23:50.920 --> 0:23:54.440
<v Speaker 1>integral to the evolution of galaxy clusters in the way

0:23:54.440 --> 0:23:56.800
<v Speaker 1>that they form. So there you have it, Walls. I

0:23:57.040 --> 0:23:59.080
<v Speaker 1>would be remiss if I didn't mention Game of Thrones

0:23:59.119 --> 0:24:02.679
<v Speaker 1>real quick finger with this book series, h and HBO

0:24:02.760 --> 0:24:05.000
<v Speaker 1>TV series. I have heard you speak of it, and

0:24:05.080 --> 0:24:07.240
<v Speaker 1>I know of it. I have not seen it that well,

0:24:07.280 --> 0:24:10.000
<v Speaker 1>it's very entertaining and part of the plot revolves arounding

0:24:10.040 --> 0:24:14.240
<v Speaker 1>northern Wall that is built against our barians and demons,

0:24:14.640 --> 0:24:16.639
<v Speaker 1>though in this case built out of ice, and the

0:24:16.680 --> 0:24:19.399
<v Speaker 1>series explore some of the ideas of at least the

0:24:19.600 --> 0:24:22.400
<v Speaker 1>military ideas that we discuss with a Great Wall of China,

0:24:22.480 --> 0:24:24.480
<v Speaker 1>like how do you maintain it? How does a political

0:24:24.520 --> 0:24:27.800
<v Speaker 1>climate affect the maintenance and the staffing of the wall,

0:24:28.280 --> 0:24:32.000
<v Speaker 1>and then is it ultimately an effective barrier against these

0:24:32.200 --> 0:24:35.880
<v Speaker 1>outside forces? Well, I'm just gonna guess, Well, it would

0:24:35.920 --> 0:24:37.879
<v Speaker 1>make a good story. How would you write seven books

0:24:37.880 --> 0:24:40.280
<v Speaker 1>about it? Um? Seven plus books about it? If that's

0:24:40.280 --> 0:24:42.080
