1 00:00:05,760 --> 00:00:07,600 Speaker 1: Hey, Daniel, do you ever think about what it would 2 00:00:07,680 --> 00:00:11,239 Speaker 1: be like if we were visited by aliens? Oh? My god, 3 00:00:11,320 --> 00:00:13,800 Speaker 1: I think about that all the time. Do you really 4 00:00:14,120 --> 00:00:16,320 Speaker 1: what do you think would happen? Well, in my imagination, 5 00:00:16,320 --> 00:00:18,960 Speaker 1: it always starts the same way. There's some sleepy guy 6 00:00:19,040 --> 00:00:21,480 Speaker 1: in front of a terminal somewhere which starts to blink 7 00:00:21,760 --> 00:00:23,439 Speaker 1: and then annoy him and wake him up, and he 8 00:00:23,440 --> 00:00:25,880 Speaker 1: looks it up and he rubs his face and he goes, hmmm, 9 00:00:26,360 --> 00:00:30,360 Speaker 1: that's weird. Isn't that what happens in like every single 10 00:00:30,440 --> 00:00:34,720 Speaker 1: science witchian movie ever? Exactly? Um? And you know the 11 00:00:34,760 --> 00:00:37,040 Speaker 1: cool thing is that it's actually happened a few times 12 00:00:37,080 --> 00:00:40,240 Speaker 1: in real life. Yeah, that's right. Didn't happen just last year? Yeah, 13 00:00:40,280 --> 00:00:42,639 Speaker 1: it happened last year. It also happened in the seventies 14 00:00:42,680 --> 00:00:44,720 Speaker 1: when we got a weird signal from space called the 15 00:00:44,720 --> 00:00:49,000 Speaker 1: Wow signal. So sometimes we do we see weird things 16 00:00:49,080 --> 00:00:51,760 Speaker 1: coming at us from space. But it happened as recently 17 00:00:51,800 --> 00:00:55,440 Speaker 1: as last year. That's right, last year. Was it aliens? 18 00:00:55,640 --> 00:00:58,680 Speaker 1: We still don't know. We do know that it was weird, 19 00:00:58,960 --> 00:01:06,280 Speaker 1: how weird? Unquantifiably weird? Was it? Um? I'm a little weird. 20 00:01:07,520 --> 00:01:12,120 Speaker 1: It was more weird than you think. That's what I 21 00:01:12,200 --> 00:01:31,600 Speaker 1: was looking for. Hi, I'm and I'm Daniel, and welcome 22 00:01:31,600 --> 00:01:34,959 Speaker 1: to our podcast. Daniel and Jorge explain the universe, in 23 00:01:35,000 --> 00:01:37,840 Speaker 1: which we try to take everything in the universe, including 24 00:01:38,120 --> 00:01:41,560 Speaker 1: weird things from outer space, and explain them to you, 25 00:01:41,800 --> 00:01:46,160 Speaker 1: even if they're inexplicable. That's right, even those unwanted visitors. 26 00:01:46,360 --> 00:01:48,680 Speaker 1: What do you mean unwanted? I want a visitor, You 27 00:01:48,680 --> 00:01:51,880 Speaker 1: want a visitor. Yeah, Aliens, come on down here. Tell 28 00:01:51,960 --> 00:01:54,000 Speaker 1: us all about how the rest of the galaxy works. 29 00:01:54,240 --> 00:01:56,120 Speaker 1: Tell us about the rest of the universe. We need 30 00:01:56,200 --> 00:01:58,320 Speaker 1: some more data. I'm dying to know what's going on 31 00:01:58,360 --> 00:02:03,040 Speaker 1: out there, aren't you? And slaves ITAs, You're so cynical. No, 32 00:02:03,200 --> 00:02:05,200 Speaker 1: it's very likely if aliens arived that they will just 33 00:02:05,240 --> 00:02:07,240 Speaker 1: take over and suck our brains out of our noses. 34 00:02:07,600 --> 00:02:11,160 Speaker 1: But in the inter the short intermission before that happens, 35 00:02:11,160 --> 00:02:13,440 Speaker 1: they might grant us some knowledge about the universe. And 36 00:02:13,520 --> 00:02:15,480 Speaker 1: you know that could be worth it. You would trade it. 37 00:02:15,520 --> 00:02:18,359 Speaker 1: You would be like, um, all yours, but first tell 38 00:02:18,360 --> 00:02:21,679 Speaker 1: me what's up with Pie? You know, if I could 39 00:02:21,680 --> 00:02:24,440 Speaker 1: have absolute knowledge of everything in the universe, Yeah, I 40 00:02:24,560 --> 00:02:27,480 Speaker 1: might uh, I might be willing to sacrifice my brain 41 00:02:27,520 --> 00:02:30,720 Speaker 1: for that. You're like, before you make me into a pie, 42 00:02:31,040 --> 00:02:36,120 Speaker 1: please explain pie to me. That's right, exactly. Well, today 43 00:02:36,120 --> 00:02:38,440 Speaker 1: on the podcast, we are going to talk about a 44 00:02:38,560 --> 00:02:42,520 Speaker 1: visitor to our solar system, one that not not a 45 00:02:42,560 --> 00:02:47,440 Speaker 1: single scientist can really explain. That's right. Last year of actually, 46 00:02:47,760 --> 00:02:51,680 Speaker 1: a strange object passed through our solar systems from somewhere 47 00:02:52,000 --> 00:02:55,320 Speaker 1: very far away, somewhere unknown, and there's a lot of 48 00:02:55,320 --> 00:02:57,840 Speaker 1: weird things about it, things that we can't quite explain. 49 00:02:58,400 --> 00:03:01,360 Speaker 1: So it's the opportunity to learn something about other parts 50 00:03:01,360 --> 00:03:04,799 Speaker 1: of the universe. It's a very suspicious object, right, Yeah, 51 00:03:04,800 --> 00:03:06,600 Speaker 1: I don't think you need to view it with suspicion. 52 00:03:06,639 --> 00:03:09,399 Speaker 1: I mean it's strange, it's unusual, it's weird. We don't 53 00:03:09,480 --> 00:03:12,480 Speaker 1: understand it. But I see as an opportunity. I mean, 54 00:03:12,520 --> 00:03:15,360 Speaker 1: it's like we've been looking out into the stars for 55 00:03:15,480 --> 00:03:17,920 Speaker 1: decades trying to learn about the rest of the universe 56 00:03:17,960 --> 00:03:20,600 Speaker 1: just by looking, Right, wouldn't it be awesome if some 57 00:03:20,680 --> 00:03:22,600 Speaker 1: of the rest of the universe came to us so 58 00:03:22,639 --> 00:03:24,640 Speaker 1: we could just like, you know, hold it and play 59 00:03:24,680 --> 00:03:26,400 Speaker 1: with it. Like the same reason we want to get 60 00:03:26,480 --> 00:03:28,800 Speaker 1: rocks from the Moon and rocks from Mars. Wouldn't you 61 00:03:28,840 --> 00:03:32,079 Speaker 1: love rocks from alien planets and other galaxies or other 62 00:03:32,080 --> 00:03:34,800 Speaker 1: solar systems. Yeah, so you're saying it's it's more like 63 00:03:34,880 --> 00:03:40,760 Speaker 1: conspicuous rather than suspicious. That's right. Yeah, it's um. It's 64 00:03:40,800 --> 00:03:48,480 Speaker 1: conspicuously suspicious or suspiciously conspicuous and probably not omniscient. Um. 65 00:03:48,560 --> 00:03:50,560 Speaker 1: But it hasn't answered any of our questions yet. So 66 00:03:50,840 --> 00:03:53,200 Speaker 1: we have a lot of questions about this weird rock 67 00:03:53,280 --> 00:03:56,160 Speaker 1: from outer space. That's right. Today on the podcast we'll 68 00:03:56,200 --> 00:04:06,680 Speaker 1: be talking about what is it, Where did it come from, 69 00:04:06,720 --> 00:04:09,080 Speaker 1: Where where is it going? Why did it stop by 70 00:04:09,120 --> 00:04:13,120 Speaker 1: our solar system? Isn't it Hawaiian? Maybe just like Hawaiian pizza? 71 00:04:13,320 --> 00:04:17,080 Speaker 1: I don't know. You know, the name comes from a 72 00:04:17,120 --> 00:04:21,000 Speaker 1: word in the Hawaiian language, right, Mua means scout or 73 00:04:21,120 --> 00:04:24,600 Speaker 1: like distant messenger or something. It's sort of a funny name. 74 00:04:24,680 --> 00:04:27,120 Speaker 1: But be careful how you pronounce it because it's it's 75 00:04:27,320 --> 00:04:30,080 Speaker 1: starts out with a letter that's not really a letter. 76 00:04:30,200 --> 00:04:33,120 Speaker 1: It's like this, um, you write it as an apostrophe. 77 00:04:33,160 --> 00:04:35,720 Speaker 1: It's a glottal stop. So I'm not even sure how 78 00:04:35,760 --> 00:04:38,159 Speaker 1: officially to pronounce this thing. So not only is the 79 00:04:38,279 --> 00:04:41,240 Speaker 1: rock weird, but the word for the rock is like 80 00:04:41,360 --> 00:04:44,760 Speaker 1: difficult to understand. We should do a whole podcast on 81 00:04:44,960 --> 00:04:50,880 Speaker 1: glottal stops on who names these things? Anyway, it's sort 82 00:04:50,880 --> 00:04:52,560 Speaker 1: of a noble name. It's supposed to be a noble name. 83 00:04:52,600 --> 00:04:54,680 Speaker 1: Like it's sort of like a like an explorer of 84 00:04:54,720 --> 00:04:58,360 Speaker 1: the stars, right, yeah, exactly, So it's got that positive 85 00:04:58,440 --> 00:05:01,040 Speaker 1: light on. It's not like invade or and destroyer of 86 00:05:01,120 --> 00:05:04,719 Speaker 1: worlds or anything. Yeah, although scout that that makes me 87 00:05:04,760 --> 00:05:08,400 Speaker 1: think of like an advanced count, you know, like a reconnaissance. 88 00:05:08,880 --> 00:05:12,480 Speaker 1: Are you worried that aliens are gonna invade and eat you? Um? Yes? 89 00:05:15,279 --> 00:05:18,599 Speaker 1: Um so yes. So this weird rock Omumu appeared in 90 00:05:19,080 --> 00:05:22,160 Speaker 1: seventeen and we are still struggling to understand it, where 91 00:05:22,160 --> 00:05:24,800 Speaker 1: it came from, what it was wise visited us, what 92 00:05:24,880 --> 00:05:27,839 Speaker 1: it means, you know, was it artificial, was it natural? 93 00:05:27,960 --> 00:05:30,360 Speaker 1: We still don't really know. Um And so we thought 94 00:05:30,440 --> 00:05:32,400 Speaker 1: let's dig into it on this podcast and tell you 95 00:05:32,440 --> 00:05:34,919 Speaker 1: all about how it's strange and how it's interesting and 96 00:05:34,960 --> 00:05:38,440 Speaker 1: all the mysteries that still remain about this weird rock. Yeah, 97 00:05:38,440 --> 00:05:41,239 Speaker 1: it was in the news a lot last year, right, yeah, 98 00:05:41,279 --> 00:05:44,440 Speaker 1: because it it passed through and really made waves in 99 00:05:44,440 --> 00:05:47,719 Speaker 1: the astronomical community. People were like amazed to see this 100 00:05:47,800 --> 00:05:50,640 Speaker 1: kind of thing. We were wondering how far these waves 101 00:05:50,760 --> 00:05:54,480 Speaker 1: in the astronomical community made their way into the general public. 102 00:05:54,760 --> 00:05:58,440 Speaker 1: How many people out there have heard of or knew 103 00:05:58,800 --> 00:06:02,480 Speaker 1: what is momma? Yeah? Was it only astronomers, was it 104 00:06:02,520 --> 00:06:06,560 Speaker 1: astronomers plus everybody interested in alien visitation? Or was it 105 00:06:06,680 --> 00:06:09,960 Speaker 1: everybody on earth that was captivated by the passage of 106 00:06:09,960 --> 00:06:12,279 Speaker 1: this strange rock. We were curious. I just want to 107 00:06:12,279 --> 00:06:14,760 Speaker 1: know how many people can pronounce it or spell it? 108 00:06:16,720 --> 00:06:19,720 Speaker 1: That's zero. I already know the answer to that. So 109 00:06:19,760 --> 00:06:22,080 Speaker 1: as usual, Daniel went out there and asked people in 110 00:06:22,120 --> 00:06:26,479 Speaker 1: the street what was MoMA? Yeah? I asked them have 111 00:06:26,560 --> 00:06:29,279 Speaker 1: you heard of omamua? And if they answered yes, I 112 00:06:29,320 --> 00:06:33,560 Speaker 1: also asked them what they thought it was. Well, here's 113 00:06:33,600 --> 00:06:38,120 Speaker 1: what people had to say. No, okay, no, I'm not 114 00:06:38,360 --> 00:06:42,520 Speaker 1: I'm sorry, I'm not her. Yeah I did not okay, 115 00:06:42,800 --> 00:06:49,000 Speaker 1: no I never heard of it? No all right, no, no, no, okay, yes, 116 00:06:49,760 --> 00:06:52,560 Speaker 1: what do you think? It is? Probably just some kind 117 00:06:52,640 --> 00:06:55,680 Speaker 1: of space debris. I did not hear about that, Okay, 118 00:06:55,960 --> 00:06:58,160 Speaker 1: I just what do you think it was probably some 119 00:06:58,240 --> 00:07:00,360 Speaker 1: kind of meteor. I just think it was like a 120 00:07:01,000 --> 00:07:05,640 Speaker 1: like a meteor off. Okay, No, I did not know. Okay, alright, 121 00:07:05,680 --> 00:07:07,840 Speaker 1: So about like fifty fifty half of the people seem 122 00:07:07,920 --> 00:07:11,000 Speaker 1: to know or have heard about it, and have the 123 00:07:11,040 --> 00:07:13,360 Speaker 1: people had no idea? I never heard of it. Yes, 124 00:07:13,400 --> 00:07:16,880 Speaker 1: what do you think of the Astronomy Communities pr PR machine? 125 00:07:17,000 --> 00:07:20,000 Speaker 1: Apparently it must be better than the aliens PR machinery, 126 00:07:22,160 --> 00:07:24,360 Speaker 1: But don't don't you think they could have done mua 127 00:07:24,440 --> 00:07:31,000 Speaker 1: mua with it? I think we should stop with the 128 00:07:35,000 --> 00:07:38,480 Speaker 1: all right, that officially ends them puns. Yeah, most people 129 00:07:38,520 --> 00:07:40,400 Speaker 1: had never even heard of this thing, which to me 130 00:07:40,480 --> 00:07:43,280 Speaker 1: boggles the mind, Like what an incredible event to happen, 131 00:07:43,440 --> 00:07:45,360 Speaker 1: and just for people to be unaware of it, you 132 00:07:45,360 --> 00:07:47,720 Speaker 1: know it all the newspapers and people were talking about it. 133 00:07:47,840 --> 00:07:49,600 Speaker 1: How could you just go through your normal life and 134 00:07:49,680 --> 00:07:53,320 Speaker 1: not know that there's a potential alien ship flying through 135 00:07:53,320 --> 00:07:56,040 Speaker 1: the Solar System? Right? I feel like maybe people are jaded, 136 00:07:56,160 --> 00:07:58,720 Speaker 1: you know, when they see an headline it goes put 137 00:07:58,800 --> 00:08:03,320 Speaker 1: possible alien visiting the Solar System. People just I don't 138 00:08:03,320 --> 00:08:06,000 Speaker 1: know these days, it's all it's just kind of all 139 00:08:06,160 --> 00:08:08,440 Speaker 1: part of the noise it goes through people's feeds. You mean, 140 00:08:08,520 --> 00:08:10,760 Speaker 1: because the world is so crazy that doesn't seem so 141 00:08:10,800 --> 00:08:13,520 Speaker 1: crazy anymore, or because you see that kind of headline 142 00:08:13,720 --> 00:08:17,600 Speaker 1: pretty often. Well, I think it's because, um, like the 143 00:08:17,920 --> 00:08:20,320 Speaker 1: headline itself sounds huge, but it's not like on the 144 00:08:20,400 --> 00:08:24,000 Speaker 1: front page of newspapers or website, do you know what 145 00:08:24,040 --> 00:08:26,520 Speaker 1: I mean? Like it it sounds like it should be 146 00:08:26,520 --> 00:08:28,560 Speaker 1: a huge deal, but you know, obviously people are not 147 00:08:28,600 --> 00:08:30,920 Speaker 1: freaking out about it. So you know, I think as 148 00:08:31,080 --> 00:08:34,640 Speaker 1: as news consumers, you just assume that it's hyperbole or 149 00:08:34,679 --> 00:08:37,840 Speaker 1: clickbait or something. Oh, I see everybody's lying, so everything 150 00:08:37,920 --> 00:08:40,520 Speaker 1: must be a lie. Right, Yeah, that's a bummer. So 151 00:08:40,520 --> 00:08:43,000 Speaker 1: when aliens, when aliens actually land, you're gonna be like whatever, 152 00:08:43,040 --> 00:08:45,680 Speaker 1: you're just clickbait, go away. Well, I mean, it's not 153 00:08:45,720 --> 00:08:47,720 Speaker 1: on the front page, right, Like, it's not you know, 154 00:08:47,760 --> 00:08:50,120 Speaker 1: it's not dominating the conversation. It's hard for me to 155 00:08:50,160 --> 00:08:53,440 Speaker 1: remember because I obviously pay attention to the scientific news, 156 00:08:53,480 --> 00:08:55,719 Speaker 1: maybe more than the average person. To me, it was 157 00:08:55,760 --> 00:08:58,920 Speaker 1: in the front of my brain for for a long time. Um, 158 00:08:58,960 --> 00:09:01,600 Speaker 1: but yeah, maybe for the averag person it was just 159 00:09:01,840 --> 00:09:06,120 Speaker 1: you know, a minor interesting thing that astronomers saw. Well, 160 00:09:06,160 --> 00:09:08,400 Speaker 1: let's break it down for people. Um, so what was 161 00:09:08,480 --> 00:09:11,559 Speaker 1: this thing called. So this is a thing that was 162 00:09:11,640 --> 00:09:14,280 Speaker 1: seen by a telescope in Hawaii. It's called the Pan 163 00:09:14,400 --> 00:09:18,040 Speaker 1: Stars telescope, and it basically just turned on. Is this 164 00:09:18,280 --> 00:09:21,520 Speaker 1: gorgeous new telescope and they're supposed to be looking deep 165 00:09:21,559 --> 00:09:26,320 Speaker 1: into outer space and understanding how the how the cosmos 166 00:09:26,360 --> 00:09:29,559 Speaker 1: that are evolving, and how supernova are exploding and all 167 00:09:29,559 --> 00:09:32,959 Speaker 1: that's kind of fascinating astronomical and cosmological questions. What makes 168 00:09:33,000 --> 00:09:36,400 Speaker 1: that telescope gorgeous? It can see really far into the past, 169 00:09:36,600 --> 00:09:39,600 Speaker 1: and so to me, that's just gorgeous. Like every time 170 00:09:39,640 --> 00:09:41,680 Speaker 1: we open our eyes in a new way or open 171 00:09:41,720 --> 00:09:44,360 Speaker 1: a new set of eyes, we see more of the universe, 172 00:09:44,360 --> 00:09:47,160 Speaker 1: and the universe is beautiful. I mean that's purely subjective, 173 00:09:47,200 --> 00:09:49,400 Speaker 1: but to me, when I look at in space, I 174 00:09:49,520 --> 00:09:52,360 Speaker 1: see beauty, and so I love when we turn on 175 00:09:52,480 --> 00:09:54,800 Speaker 1: new eyes and we can see new areas of the 176 00:09:54,840 --> 00:09:56,920 Speaker 1: universe we've never seen before. And that's where the Pan 177 00:09:57,000 --> 00:10:00,360 Speaker 1: Stars Telescope allowed us to do. Beautiful way to say it, 178 00:10:01,160 --> 00:10:04,280 Speaker 1: And so they turned this thing on and pretty quickly 179 00:10:04,320 --> 00:10:07,880 Speaker 1: they saw something weird. They saw this rock moving really 180 00:10:07,920 --> 00:10:12,440 Speaker 1: really fast tom into our solar system, and you might think, well, 181 00:10:12,520 --> 00:10:14,240 Speaker 1: there's a lot of rocks in the solar system, right, 182 00:10:14,240 --> 00:10:15,960 Speaker 1: how can you tell that this one is weird? Or 183 00:10:16,000 --> 00:10:18,360 Speaker 1: what's weird about this one? And the weird thing about 184 00:10:18,400 --> 00:10:21,839 Speaker 1: this one where its direction and its speed? Wait, so 185 00:10:22,000 --> 00:10:24,920 Speaker 1: why didn't other telescope see it? Why did it require 186 00:10:25,000 --> 00:10:27,520 Speaker 1: this brand new, gorgeous telescope. Well, this is one of 187 00:10:27,559 --> 00:10:30,439 Speaker 1: the more powerful telescopes we have. I think other telescopes 188 00:10:30,440 --> 00:10:32,000 Speaker 1: could have seen it. There's also just a little bit 189 00:10:32,040 --> 00:10:34,000 Speaker 1: of luck and who spotted it first. You happen to 190 00:10:34,000 --> 00:10:36,320 Speaker 1: be looking in the right place, and also you happen 191 00:10:36,360 --> 00:10:38,320 Speaker 1: to notice it. You know, a lot of times you 192 00:10:38,360 --> 00:10:41,120 Speaker 1: turn on your telescope and you're looking for thing A 193 00:10:41,720 --> 00:10:44,439 Speaker 1: and you accidentally discover thing B. But only if you're 194 00:10:44,440 --> 00:10:46,920 Speaker 1: curious enough. Right, if you see something weird in your 195 00:10:47,000 --> 00:10:48,800 Speaker 1: data and you're like, huh, I don't understand that, what 196 00:10:48,880 --> 00:10:51,400 Speaker 1: could that be? You could just shrug and say I 197 00:10:51,400 --> 00:10:53,640 Speaker 1: don't know whatever and move on with your life. Or 198 00:10:53,679 --> 00:10:55,559 Speaker 1: you could follow it up and try to figure it out. 199 00:10:55,600 --> 00:10:58,480 Speaker 1: And sometimes that's where the greatest discoveries are made. You know. 200 00:10:58,520 --> 00:11:00,839 Speaker 1: That's how like Pluto was discovered it or that's how 201 00:11:00,880 --> 00:11:04,440 Speaker 1: pulsars were discovered. All these things were accidents, is things. 202 00:11:04,559 --> 00:11:07,120 Speaker 1: People saw something weird in their data. It didn't just 203 00:11:07,120 --> 00:11:09,679 Speaker 1: blow off their curiosity. They followed it up, right. Yeah, 204 00:11:09,720 --> 00:11:15,360 Speaker 1: that worked out really well for Pluto. I think Pluto's 205 00:11:15,440 --> 00:11:20,280 Speaker 1: legal team is still fighting that battle. It's posthumous legal team. 206 00:11:20,400 --> 00:11:24,800 Speaker 1: It's not dead. We didn't kill Pluto's still there, That's 207 00:11:24,840 --> 00:11:32,720 Speaker 1: what the book says. So they turned on this telescope 208 00:11:32,760 --> 00:11:36,040 Speaker 1: and they basically saw stars and things out there, and 209 00:11:36,080 --> 00:11:39,240 Speaker 1: they saw one of them moving in a weird direction 210 00:11:39,320 --> 00:11:41,720 Speaker 1: at weird speed. Yeah, and there's a lot of weird 211 00:11:41,720 --> 00:11:44,120 Speaker 1: things out there. Right. We have planets in our Solar system. 212 00:11:44,160 --> 00:11:47,239 Speaker 1: We have asteroids, we have we have a lot of asteroids. 213 00:11:47,240 --> 00:11:49,880 Speaker 1: We even have comets, right, And commets move differently, but 214 00:11:50,040 --> 00:11:53,320 Speaker 1: everything in the Solar System shares one feature, which is 215 00:11:53,480 --> 00:11:57,120 Speaker 1: they're moving around the Sun. Right. They're gravitationally bound by 216 00:11:57,160 --> 00:11:59,760 Speaker 1: the Sun. They're in a stable orbit. So even comets 217 00:12:00,040 --> 00:12:02,160 Speaker 1: that come in every hundred years and then zoom out 218 00:12:02,160 --> 00:12:06,240 Speaker 1: really far, they're still moving around the Sun right there there, 219 00:12:05,720 --> 00:12:09,840 Speaker 1: and the focus of their orbit is the Sun. And 220 00:12:10,520 --> 00:12:13,640 Speaker 1: this object was moving in a way that's totally inconsistent 221 00:12:13,760 --> 00:12:17,120 Speaker 1: with being in an orbit around the Sun any orbit. Right, 222 00:12:17,360 --> 00:12:19,400 Speaker 1: It was going way too fast in the wrong direction. 223 00:12:19,480 --> 00:12:23,000 Speaker 1: You mean, we've never seen an asteroid or anything else. 224 00:12:23,440 --> 00:12:26,000 Speaker 1: It wasn't revolving around our Sun. Is that what you're saying. 225 00:12:26,160 --> 00:12:29,400 Speaker 1: That's exactly what I'm saying. We've never seen anything never. 226 00:12:29,480 --> 00:12:31,960 Speaker 1: It wasn't gravitationally bound to the Sun. This is the 227 00:12:32,000 --> 00:12:34,800 Speaker 1: first time we've seen something that looks like it came 228 00:12:34,840 --> 00:12:38,559 Speaker 1: from another Sun. And we could tell just by the motion. Right, 229 00:12:38,600 --> 00:12:40,520 Speaker 1: that's there's none from We'll talk later about what it 230 00:12:40,520 --> 00:12:42,319 Speaker 1: looks like and how weird it is in the shape 231 00:12:42,360 --> 00:12:44,840 Speaker 1: of it, but just from its motion, we could tell 232 00:12:45,120 --> 00:12:48,440 Speaker 1: that it didn't come from our solar system because it 233 00:12:48,520 --> 00:12:51,800 Speaker 1: was moving too fast or in a weird trajectory, or 234 00:12:51,840 --> 00:12:53,640 Speaker 1: what do you mean both. It was moving in a 235 00:12:53,640 --> 00:12:55,319 Speaker 1: trajectory that made it clear it was not going to 236 00:12:55,400 --> 00:12:58,800 Speaker 1: stick around. Right. They saw it moving, and they could 237 00:12:58,880 --> 00:13:01,040 Speaker 1: plot its speed and its direction, so they could tell 238 00:13:01,080 --> 00:13:02,559 Speaker 1: where it was going to go, and they could tell 239 00:13:02,600 --> 00:13:05,559 Speaker 1: it was just going to go right through our solar system. 240 00:13:05,600 --> 00:13:07,440 Speaker 1: It wasn't moving around the Sun. So we could get 241 00:13:07,480 --> 00:13:08,640 Speaker 1: lots of looks at it. It It was just going to 242 00:13:08,720 --> 00:13:11,800 Speaker 1: pass through once, and how do we figure out how 243 00:13:11,840 --> 00:13:13,959 Speaker 1: far it was? How do we figure out how far 244 00:13:14,000 --> 00:13:17,160 Speaker 1: away it is? Um, that's a good question. You know. 245 00:13:17,240 --> 00:13:20,080 Speaker 1: We did a whole episode about measuring distances to things, 246 00:13:20,400 --> 00:13:22,439 Speaker 1: and so I think you can tell how far away 247 00:13:22,440 --> 00:13:26,559 Speaker 1: things are using parallax seeing, you know, multiple measurements that 248 00:13:26,920 --> 00:13:28,880 Speaker 1: that are spaced far apart, sort of the way your 249 00:13:28,880 --> 00:13:31,240 Speaker 1: eyes work, and so within the solar system, I think 250 00:13:31,280 --> 00:13:33,520 Speaker 1: that works pretty well because things aren't that far away. 251 00:13:33,920 --> 00:13:35,679 Speaker 1: So you can tell how far away things are by 252 00:13:35,679 --> 00:13:38,200 Speaker 1: saying how differently they look or how much they move 253 00:13:38,679 --> 00:13:41,920 Speaker 1: from different viewpoints, So you multiple telescopes, or you look 254 00:13:41,960 --> 00:13:44,040 Speaker 1: at the same thing over several days as the Earth 255 00:13:44,120 --> 00:13:46,640 Speaker 1: is moving. That's a great question. I'm not sure, but 256 00:13:46,720 --> 00:13:49,000 Speaker 1: that's how I would do it. And it wasn't just 257 00:13:49,080 --> 00:13:52,920 Speaker 1: moving a little bit fast relative to our solar system. 258 00:13:53,120 --> 00:13:56,360 Speaker 1: It was a moving something like twenty six kilometers per 259 00:13:56,520 --> 00:14:01,000 Speaker 1: second faster than we were per second. Yeah, exactly, That's 260 00:14:01,040 --> 00:14:03,240 Speaker 1: that's pretty fast. It's like, in a second, wish you 261 00:14:03,320 --> 00:14:05,280 Speaker 1: just went twenty six kilometers. I wish I could go 262 00:14:05,800 --> 00:14:08,000 Speaker 1: ko per second. You know, maybe Tesla's can do that. 263 00:14:08,000 --> 00:14:10,360 Speaker 1: I don't know the too. What is it called the 264 00:14:11,160 --> 00:14:14,600 Speaker 1: hyper exactly? It was basically hyperlooping through our solar system. 265 00:14:14,679 --> 00:14:17,720 Speaker 1: Yeah yeah, it's fast, right, like it's um, nothing really 266 00:14:17,720 --> 00:14:20,160 Speaker 1: moved that fast in our solar system. Um. Yeah, And 267 00:14:20,160 --> 00:14:22,640 Speaker 1: even comets that approached the Sun they speed up really 268 00:14:22,640 --> 00:14:24,920 Speaker 1: fast and then you'll go this fast right Yeah, so 269 00:14:24,960 --> 00:14:27,240 Speaker 1: it was moving pretty quick. It's like seeing a freight 270 00:14:27,320 --> 00:14:30,800 Speaker 1: freight train coming at in your direction really really fast, 271 00:14:30,800 --> 00:14:32,520 Speaker 1: and you're like, Okay, that thing is not going to 272 00:14:32,600 --> 00:14:35,880 Speaker 1: stop where I am. It's going so fast. Yeah, exactly, 273 00:14:36,360 --> 00:14:38,480 Speaker 1: And fortunately it didn't pass too close to the Earth 274 00:14:38,600 --> 00:14:40,800 Speaker 1: or unfortunately if you wanted us to get a better look. 275 00:14:41,040 --> 00:14:44,840 Speaker 1: It passed within like fifteen million miles of the Earth. Wow, 276 00:14:44,960 --> 00:14:47,200 Speaker 1: that sounds like a lot. Is that a lot? You know? 277 00:14:47,320 --> 00:14:50,960 Speaker 1: It's um, it's a significant It's like, um, fifteen percent 278 00:14:51,080 --> 00:14:53,160 Speaker 1: of the distance between the Earth and the Sun, so 279 00:14:53,480 --> 00:14:57,880 Speaker 1: asteroids passed much closer all the time. Fifteen percent. So 280 00:14:58,120 --> 00:15:02,320 Speaker 1: from here the Sun, it's a hundred million miles, million miles, 281 00:15:02,880 --> 00:15:05,320 Speaker 1: million miles from here to the side. So it's it's 282 00:15:05,360 --> 00:15:07,520 Speaker 1: pretty close. I mean, it's not like it went over 283 00:15:07,560 --> 00:15:10,880 Speaker 1: our heads, like it came sort of into this solar system. Oh, 284 00:15:10,880 --> 00:15:13,000 Speaker 1: it definitely went right through the solar system. Yeah. I 285 00:15:13,000 --> 00:15:15,480 Speaker 1: think your freight train analogy is a perfect one. You know, 286 00:15:15,840 --> 00:15:18,000 Speaker 1: you're in a house and you're here, this freight train 287 00:15:18,160 --> 00:15:20,200 Speaker 1: rumbled by, and you're like, yesh, that was kind of 288 00:15:20,240 --> 00:15:23,160 Speaker 1: loud and close and weird, and it definitely didn't stop 289 00:15:23,160 --> 00:15:25,040 Speaker 1: in your town, right, just like blew right through like 290 00:15:25,080 --> 00:15:29,960 Speaker 1: you weren't even there. That's frightening. Yeah, And and it's 291 00:15:30,000 --> 00:15:32,040 Speaker 1: not even that big, you know, the thing is like 292 00:15:32,520 --> 00:15:34,880 Speaker 1: it's we were not sure exactly because we don't have 293 00:15:34,920 --> 00:15:37,400 Speaker 1: great pictures of it. It was moving so fast and 294 00:15:37,400 --> 00:15:39,800 Speaker 1: it was so far away that we didn't that all 295 00:15:39,840 --> 00:15:41,720 Speaker 1: of our telescopes just see it basically as a point 296 00:15:41,760 --> 00:15:44,600 Speaker 1: of light. So we have some estimates for its size 297 00:15:44,600 --> 00:15:47,360 Speaker 1: and its shape um based on you know, how we 298 00:15:47,400 --> 00:15:50,400 Speaker 1: think it's rotating, etcetera. But the thing was not that big. 299 00:15:50,440 --> 00:15:52,800 Speaker 1: Like the dimensions are like, you know, a few hundred 300 00:15:52,880 --> 00:15:56,520 Speaker 1: meters in the longest dimension and like tens of meters 301 00:15:56,600 --> 00:15:59,280 Speaker 1: or maybe a hundreds in the other. So we are 302 00:15:59,360 --> 00:16:01,360 Speaker 1: lucky to even e this rock. You know, rocks can 303 00:16:01,400 --> 00:16:03,840 Speaker 1: fly through our solar system without us noticing them if 304 00:16:03,840 --> 00:16:06,880 Speaker 1: they don't like reflect light just the right moments so 305 00:16:06,920 --> 00:16:08,400 Speaker 1: that we can see them from the sun, because these 306 00:16:08,400 --> 00:16:11,160 Speaker 1: things don't glow right there dark unless they're reflecting light 307 00:16:11,160 --> 00:16:14,120 Speaker 1: from the sun. I see. Wow. Okay, so let's talk 308 00:16:14,160 --> 00:16:18,040 Speaker 1: about where it came from potentially or which from which 309 00:16:18,080 --> 00:16:34,280 Speaker 1: direction it came, But first let's take a break. Okay, 310 00:16:34,280 --> 00:16:39,440 Speaker 1: So I read that this object apparently came from Las Vegas. 311 00:16:39,640 --> 00:16:42,960 Speaker 1: Is that that's right? It had a crazy night in Vegas. 312 00:16:43,000 --> 00:16:45,920 Speaker 1: It has no explanation for why it's so weird, the 313 00:16:45,960 --> 00:16:48,400 Speaker 1: home of rock and roll, right, so rocks that would 314 00:16:48,400 --> 00:16:52,560 Speaker 1: make sense, and it just rolled on though our solar system. Yeah, 315 00:16:53,200 --> 00:16:56,400 Speaker 1: um no, but you're close. It came from the direction 316 00:16:56,480 --> 00:16:59,520 Speaker 1: of Vega, right. We can tell it's trajectory, and we 317 00:17:00,040 --> 00:17:02,480 Speaker 1: um extrapolate back. We're like, oh, what's in that direction 318 00:17:02,520 --> 00:17:04,960 Speaker 1: in the sky, and that the answer is Vega. Vega 319 00:17:05,000 --> 00:17:06,560 Speaker 1: is kind of interesting because it's it's kind of a 320 00:17:06,600 --> 00:17:10,639 Speaker 1: nearby star, right, think it's one among the sort of 321 00:17:10,680 --> 00:17:13,760 Speaker 1: closer stars. Right. Yeah, but this thing, even traveling at 322 00:17:13,800 --> 00:17:16,240 Speaker 1: its high speed, would take hundreds of thousands of years 323 00:17:16,240 --> 00:17:20,239 Speaker 1: to get here from Vega. So it's close, you know, 324 00:17:20,320 --> 00:17:22,480 Speaker 1: sort of on a galactic scale, but it's not really 325 00:17:22,520 --> 00:17:25,159 Speaker 1: close on a you know, um, let's go out for 326 00:17:25,160 --> 00:17:27,320 Speaker 1: dinner kind of scale. So it just sort of came 327 00:17:27,359 --> 00:17:30,879 Speaker 1: from Vegas, from Vega, right, And again we don't know 328 00:17:30,920 --> 00:17:32,520 Speaker 1: that it came from that system. It's just sort of 329 00:17:33,040 --> 00:17:35,680 Speaker 1: answering the question what's in the sky in that direction? 330 00:17:35,800 --> 00:17:37,960 Speaker 1: We can extrapolate back and say, oh, came that way, 331 00:17:38,359 --> 00:17:40,800 Speaker 1: what else is there? But you know, Vega is in 332 00:17:40,800 --> 00:17:43,399 Speaker 1: a different place a long time ago. Everything is rotating 333 00:17:43,440 --> 00:17:46,240 Speaker 1: and moving and could have gone through that system also 334 00:17:46,359 --> 00:17:48,400 Speaker 1: from another one. Right, we have no idea how long 335 00:17:48,440 --> 00:17:51,320 Speaker 1: it's been bouncing around the galaxy. Right, and let's talk 336 00:17:51,359 --> 00:17:54,119 Speaker 1: about kind of how big it was, because it's not 337 00:17:54,200 --> 00:17:56,680 Speaker 1: like the size of Manhattan, right, Like it's it's more 338 00:17:56,720 --> 00:17:58,879 Speaker 1: like the size of it's like the sky size of 339 00:17:58,960 --> 00:18:02,359 Speaker 1: one skyscraper in Manhattan. It's like maybe up to a 340 00:18:02,400 --> 00:18:06,400 Speaker 1: kilometer long and like, you know, fifty to a hundreds 341 00:18:06,400 --> 00:18:08,520 Speaker 1: on each side, So it's it's about the size of 342 00:18:08,520 --> 00:18:12,240 Speaker 1: a skyscraper. It's like the Empire State Building to zoom 343 00:18:12,320 --> 00:18:16,080 Speaker 1: by exactly, or maybe it's the Las Vegas version. Isn't 344 00:18:16,080 --> 00:18:19,560 Speaker 1: there one of those in Las Vegas. So somewhere between 345 00:18:20,280 --> 00:18:23,520 Speaker 1: the Vegas empar Site building and the real Emparsity building 346 00:18:23,760 --> 00:18:27,560 Speaker 1: was the size of this strange, mysterious object. Wouldn't that 347 00:18:27,600 --> 00:18:29,720 Speaker 1: be amazing if we visited it and found that it 348 00:18:30,000 --> 00:18:32,520 Speaker 1: had exactly the shape of the Empire State Building, that 349 00:18:32,520 --> 00:18:36,399 Speaker 1: would be pretty odd. That would be more amazing. That 350 00:18:36,440 --> 00:18:38,760 Speaker 1: would be a great twist ending to the science fiction 351 00:18:38,800 --> 00:18:41,119 Speaker 1: movie Somebody's going to make about this thing, which started 352 00:18:41,160 --> 00:18:43,720 Speaker 1: with a guy in a control room looking at a 353 00:18:43,720 --> 00:18:46,679 Speaker 1: blinking light, going, that's weird. What's the Empire State Building 354 00:18:46,680 --> 00:18:48,679 Speaker 1: doing there? It's supposed to be in Vegas. I mean 355 00:18:48,720 --> 00:18:50,399 Speaker 1: it's not huge, but I mean it's not it's not 356 00:18:50,440 --> 00:18:52,199 Speaker 1: like the size of the moon, or it's not the 357 00:18:52,240 --> 00:18:56,080 Speaker 1: size of you know, the continent. It's like it's it's 358 00:18:56,080 --> 00:18:58,000 Speaker 1: sort of like, well, how big you might imagine a 359 00:18:58,040 --> 00:19:01,119 Speaker 1: spaceship to be. Yeah, exactly, it's a reasonable size for 360 00:19:01,160 --> 00:19:04,440 Speaker 1: a spaceship, which led to a lot of speculation. Right, 361 00:19:04,920 --> 00:19:07,080 Speaker 1: you might be thinking, all right, so it's a rock 362 00:19:07,119 --> 00:19:09,600 Speaker 1: from another solar system. We got rocks, They got rocks. 363 00:19:09,760 --> 00:19:12,160 Speaker 1: One of their rocks ended up in our backyard. What's 364 00:19:12,200 --> 00:19:14,600 Speaker 1: the big deal? Right? But it's kind of a big 365 00:19:14,640 --> 00:19:17,520 Speaker 1: deal because we don't expect to see this kind of rock. 366 00:19:17,720 --> 00:19:20,600 Speaker 1: What do you mean in terms of its size or 367 00:19:20,600 --> 00:19:23,480 Speaker 1: its speed or what. Well, these solar systems are really 368 00:19:23,480 --> 00:19:26,560 Speaker 1: far apart, right, And yeah, we got a bunch of rocks, 369 00:19:26,560 --> 00:19:28,400 Speaker 1: but most of those rocks are just sort of floating 370 00:19:28,400 --> 00:19:31,560 Speaker 1: around our Sun, and occasionally one of them gets kicked 371 00:19:31,600 --> 00:19:34,400 Speaker 1: off and floats away. But you know, to pass right 372 00:19:34,400 --> 00:19:37,879 Speaker 1: through another solar system is just really small odds. The 373 00:19:37,960 --> 00:19:40,879 Speaker 1: chances of the happening are tiny. Based on our understanding 374 00:19:40,880 --> 00:19:43,520 Speaker 1: of how often the Sun sort of loses rocks and 375 00:19:43,600 --> 00:19:48,120 Speaker 1: let them float into interstellar space, this should almost never happen, right, 376 00:19:48,640 --> 00:19:51,760 Speaker 1: So it's like like a rock in our meteor belt. 377 00:19:52,080 --> 00:19:54,800 Speaker 1: These are big rocks, but they hardly ever leave the 378 00:19:54,840 --> 00:19:58,080 Speaker 1: Solar system, so it's weird that there would be one 379 00:19:58,160 --> 00:20:01,639 Speaker 1: floating around randomly. That's right. And there are rocks in 380 00:20:01,640 --> 00:20:04,480 Speaker 1: our asteroid belt. But there's also this big cloud of 381 00:20:04,680 --> 00:20:08,200 Speaker 1: icy objects that forms comments called the Oort cloud o 382 00:20:08,440 --> 00:20:10,959 Speaker 1: O r T, and it's a bunch of really loosely 383 00:20:11,000 --> 00:20:13,560 Speaker 1: held objects from the Sun. And that's probably better candidates 384 00:20:13,560 --> 00:20:16,320 Speaker 1: for how we might lose rocks. Um. And you know, 385 00:20:16,400 --> 00:20:18,720 Speaker 1: they have models for how often does the Sun lose 386 00:20:18,760 --> 00:20:21,840 Speaker 1: a rock, and so they can calculate if other suns 387 00:20:21,880 --> 00:20:24,640 Speaker 1: are losing rocks about the same level, how often should 388 00:20:24,680 --> 00:20:26,719 Speaker 1: we see one of these things? And you know they 389 00:20:26,720 --> 00:20:28,879 Speaker 1: did the calculation and they're like, you know, if you 390 00:20:28,920 --> 00:20:31,119 Speaker 1: turn on the pan star's telescope, what are the chances 391 00:20:31,119 --> 00:20:34,720 Speaker 1: of seeing an extrasolar rock a rock from another solar system, 392 00:20:34,760 --> 00:20:37,359 Speaker 1: like within the first few months, and the odds are 393 00:20:37,359 --> 00:20:39,520 Speaker 1: like up to one in a hundred millions. You know, 394 00:20:39,520 --> 00:20:41,480 Speaker 1: it's just not the kind of thing that happens very 395 00:20:41,520 --> 00:20:45,240 Speaker 1: often because these other solar systems are far apart. Space 396 00:20:45,359 --> 00:20:49,119 Speaker 1: is pretty empty. What I mean is you hardly have 397 00:20:49,160 --> 00:20:51,240 Speaker 1: to worry about running into a rock if you're going 398 00:20:51,280 --> 00:20:55,399 Speaker 1: between stars, Yeah, exactly. You know, it's like you build 399 00:20:55,400 --> 00:20:58,040 Speaker 1: a golf course and then like a golf ball drops 400 00:20:58,040 --> 00:20:59,720 Speaker 1: out of the sky and score the hole in one, 401 00:21:00,040 --> 00:21:03,840 Speaker 1: and you're like, well, that's weird. Either golf balls fall 402 00:21:03,880 --> 00:21:05,920 Speaker 1: out of the sky a lot more often than I thought, 403 00:21:06,000 --> 00:21:09,200 Speaker 1: which makes this not so weird, or something really weird 404 00:21:09,320 --> 00:21:12,679 Speaker 1: just happened, right, And that's the situation we're in. And 405 00:21:12,720 --> 00:21:14,720 Speaker 1: so right there, it's odd, right, because it can tell 406 00:21:14,760 --> 00:21:17,119 Speaker 1: you either that we were wrong, that maybe there are 407 00:21:17,119 --> 00:21:19,280 Speaker 1: a lot more of these rocks than we thought, which 408 00:21:19,280 --> 00:21:22,280 Speaker 1: is already sort of interesting after physically right to hear 409 00:21:22,280 --> 00:21:26,480 Speaker 1: that space is full of interstellar rocks banging around, or 410 00:21:26,960 --> 00:21:29,320 Speaker 1: you know, it was just a really really rare event, 411 00:21:29,400 --> 00:21:31,680 Speaker 1: and you know, rare things happen, right, People do get 412 00:21:31,720 --> 00:21:35,119 Speaker 1: holes in one act um sometimes when they don't expect. 413 00:21:35,200 --> 00:21:38,639 Speaker 1: It's so rare things do happen. Or it's not just 414 00:21:38,680 --> 00:21:41,080 Speaker 1: a rock, maybe it's something else, right, And that's why 415 00:21:41,080 --> 00:21:43,360 Speaker 1: people dug in to understand, like what is this thing? 416 00:21:43,440 --> 00:21:45,199 Speaker 1: What is it made out of? What else can we 417 00:21:45,280 --> 00:21:51,639 Speaker 1: learn about it? Not only is it rare, but it 418 00:21:51,720 --> 00:21:54,679 Speaker 1: was also going at a very rare speed, or like 419 00:21:54,680 --> 00:21:59,800 Speaker 1: a very strange speed. Yeah, yeah, exactly. If you take 420 00:22:00,080 --> 00:22:02,720 Speaker 1: the all the stars in our neighborhood, like our star 421 00:22:02,840 --> 00:22:05,360 Speaker 1: and the nearby ones and the nearest few hundreds sort 422 00:22:05,359 --> 00:22:08,040 Speaker 1: of in our galactic neighborhood, and you average all their 423 00:22:08,080 --> 00:22:11,120 Speaker 1: speeds together, you get like, you know, imagine all those 424 00:22:11,119 --> 00:22:14,520 Speaker 1: stars are like a sloshing ocean bouncing around. You know, Um, 425 00:22:14,640 --> 00:22:17,920 Speaker 1: you gets sort of the average speed of that whole blob, right, 426 00:22:18,480 --> 00:22:21,400 Speaker 1: And this thing was going at almost exactly that speed 427 00:22:21,600 --> 00:22:25,119 Speaker 1: relative to us, right, which means you can sort of 428 00:22:25,119 --> 00:22:27,439 Speaker 1: think of it like it wasn't moving. It was just 429 00:22:27,480 --> 00:22:30,600 Speaker 1: sort of floating there in the galaxy and we moved 430 00:22:30,640 --> 00:22:32,880 Speaker 1: through it. What what do you mean, Well, you can 431 00:22:32,880 --> 00:22:35,320 Speaker 1: think if you think of like our galactic neighborhood is 432 00:22:35,320 --> 00:22:37,399 Speaker 1: like an ocean, this is like a booey sort of 433 00:22:37,440 --> 00:22:39,800 Speaker 1: floating in the ocean, right. And of course our sun 434 00:22:39,920 --> 00:22:42,800 Speaker 1: is moving relative to the galaxy and our I mean 435 00:22:43,080 --> 00:22:45,840 Speaker 1: everything is relative. Right. It passed through our solar system 436 00:22:46,160 --> 00:22:49,080 Speaker 1: or we passed our solar system over it. Are the 437 00:22:49,119 --> 00:22:51,600 Speaker 1: same statements, right, It's just how you think of the 438 00:22:51,640 --> 00:22:54,600 Speaker 1: frame of reference, meaning like like we are the visitors 439 00:22:54,640 --> 00:22:57,760 Speaker 1: to it. That's right. It was just having a nice 440 00:22:57,800 --> 00:22:59,760 Speaker 1: picnic and we just sort of stormed down the loop. 441 00:23:00,119 --> 00:23:04,400 Speaker 1: Are the freight train? Not it exactly. And it's it's 442 00:23:04,400 --> 00:23:07,120 Speaker 1: a really odd kind of speed because it doesn't help 443 00:23:07,160 --> 00:23:09,040 Speaker 1: us understand where it came from. Like, if it came 444 00:23:09,119 --> 00:23:12,000 Speaker 1: from the neighboring star, we would expect it to roughly 445 00:23:12,040 --> 00:23:15,800 Speaker 1: have that star's velocity with respect to the galaxy. Right, Um, 446 00:23:15,840 --> 00:23:17,800 Speaker 1: if it came from another star, we you'd expected to 447 00:23:17,880 --> 00:23:21,680 Speaker 1: have that star's velocity roughly, but it but no stars 448 00:23:21,760 --> 00:23:24,520 Speaker 1: have this average velocity, right, most of them are moving 449 00:23:24,840 --> 00:23:27,639 Speaker 1: relative to the galaxy. They're slashing around, So it's a 450 00:23:27,680 --> 00:23:32,159 Speaker 1: pretty weird speed to have. It's an anomaly kind of 451 00:23:32,200 --> 00:23:36,040 Speaker 1: like it's clear it didn't come from possibly the stars 452 00:23:36,080 --> 00:23:39,399 Speaker 1: around us, And so the anomalies start to add up. Right, 453 00:23:39,400 --> 00:23:41,280 Speaker 1: You're like, oh, well, maybe it's just a rock from 454 00:23:41,320 --> 00:23:44,720 Speaker 1: another solar system. Um, okay, Well, actually turns out those 455 00:23:44,720 --> 00:23:47,040 Speaker 1: are really rare. You're like, all right, well, rare things happen, 456 00:23:47,400 --> 00:23:49,800 Speaker 1: but the rare things for this rock keep adding up. 457 00:23:49,880 --> 00:23:53,960 Speaker 1: It's rare and weird in so many different, totally separate 458 00:23:53,960 --> 00:23:56,880 Speaker 1: ways that it really makes you start to wonder. And 459 00:23:56,960 --> 00:23:59,880 Speaker 1: I think the shape has allowed to do when capturing 460 00:23:59,880 --> 00:24:02,320 Speaker 1: the public's imagination. Like, um, you know, if you had 461 00:24:02,359 --> 00:24:04,520 Speaker 1: been like a like a ball or like a rock, 462 00:24:04,880 --> 00:24:07,800 Speaker 1: like a you know, like a randomly shaped rock, then 463 00:24:07,920 --> 00:24:10,520 Speaker 1: people would just say, oh, it's an asteroid. But the 464 00:24:10,560 --> 00:24:13,640 Speaker 1: shape of it was also very very weird. Yeah, it's 465 00:24:13,680 --> 00:24:16,879 Speaker 1: like ten times longer than it is wide right, it 466 00:24:16,920 --> 00:24:20,600 Speaker 1: looks like a skyscraper. And they had all these drawings 467 00:24:20,640 --> 00:24:23,879 Speaker 1: of like cigar shaped rocks or whatever, and let me 468 00:24:23,960 --> 00:24:27,720 Speaker 1: just interject a little rant here about astronomy public relations. 469 00:24:28,080 --> 00:24:31,200 Speaker 1: Every time we hear a story about astronomy, they always 470 00:24:31,240 --> 00:24:35,240 Speaker 1: include an artist's conception what this thing might look like? Right, 471 00:24:36,000 --> 00:24:40,000 Speaker 1: and it's and sometimes it's labeled very clearly artist conception 472 00:24:40,280 --> 00:24:42,800 Speaker 1: basically made up, But often it's not. You know, it's 473 00:24:42,800 --> 00:24:44,560 Speaker 1: just like they have this image that leads the article 474 00:24:44,600 --> 00:24:46,720 Speaker 1: and people look at it like, oh, that's what it 475 00:24:46,760 --> 00:24:49,240 Speaker 1: looks like, but we don't know what this thing looks like. 476 00:24:49,480 --> 00:24:52,440 Speaker 1: Some artists sat down and imagined maybe it looks like this. 477 00:24:52,840 --> 00:24:55,479 Speaker 1: Another artist would have made something totally different, and so 478 00:24:55,520 --> 00:24:58,080 Speaker 1: it always frustrates me. I imagine, like in particle physics, 479 00:24:58,359 --> 00:25:00,919 Speaker 1: can we have an artist and pression of what my 480 00:25:01,040 --> 00:25:03,560 Speaker 1: data might look like? Come? Why do you guys do 481 00:25:03,600 --> 00:25:05,720 Speaker 1: that all the time too? In particle physics? Don't you 482 00:25:05,840 --> 00:25:10,480 Speaker 1: like the large hatdrink Clyder, Here is some big explosion 483 00:25:10,560 --> 00:25:14,080 Speaker 1: with things coming out of the artist rendition those No, No, 484 00:25:14,240 --> 00:25:18,960 Speaker 1: that's actual data, that's actual data. Sometimes we take liberties 485 00:25:19,000 --> 00:25:21,440 Speaker 1: and we like, you know, higher clever cartoonists to make 486 00:25:21,440 --> 00:25:24,200 Speaker 1: our stuff look more interesting, But we don't make up 487 00:25:24,280 --> 00:25:30,080 Speaker 1: artists impression of data like that anyway. Um, Yes, this 488 00:25:30,160 --> 00:25:32,640 Speaker 1: thing is like ten times longer than it is whine. Yeah, 489 00:25:32,720 --> 00:25:34,920 Speaker 1: and that's kind of how a lot of times in 490 00:25:35,000 --> 00:25:39,960 Speaker 1: movies a picture space ships right from alien civilizations, like 491 00:25:40,080 --> 00:25:42,760 Speaker 1: long and skinny, kind of like the star the story 492 00:25:42,920 --> 00:25:44,840 Speaker 1: in Star Wars. Would you buy that kind of space 493 00:25:44,840 --> 00:25:46,840 Speaker 1: ship if you went shopping for one? It makes sense, right, 494 00:25:46,880 --> 00:25:48,919 Speaker 1: I mean it's sort of like, Um, it's big, but 495 00:25:48,960 --> 00:25:51,159 Speaker 1: you want it to be streamlined in a way. But 496 00:25:51,200 --> 00:25:53,200 Speaker 1: why does it have to be streamlined? There's no atmosphere 497 00:25:53,200 --> 00:25:56,160 Speaker 1: in space, right, Um, you can have any shape you want. 498 00:25:56,320 --> 00:25:58,960 Speaker 1: It doesn't have to be space so dynamic. But was 499 00:25:59,000 --> 00:26:01,000 Speaker 1: it going? Well? First of all, how did they know 500 00:26:01,160 --> 00:26:03,080 Speaker 1: was that shape it was? If it was so far 501 00:26:03,119 --> 00:26:06,040 Speaker 1: away and so small. Yeah, the reason they could tell 502 00:26:06,119 --> 00:26:08,720 Speaker 1: is that it's um. The light from it was changing 503 00:26:09,240 --> 00:26:11,920 Speaker 1: in a in a periodic way, and so they could 504 00:26:11,960 --> 00:26:14,240 Speaker 1: tell had this shape not only because it was weirdly shape, 505 00:26:14,240 --> 00:26:16,800 Speaker 1: but because it was tumbling. Right, So this thing is 506 00:26:16,840 --> 00:26:20,440 Speaker 1: not moving in a smooth way like zooming along um 507 00:26:20,520 --> 00:26:23,640 Speaker 1: in the direction of its length. You imagine a spaceship 508 00:26:23,680 --> 00:26:25,919 Speaker 1: is long and thin, it's zooming sort of in the 509 00:26:25,960 --> 00:26:28,960 Speaker 1: direction from its back to its front. Right, This thing 510 00:26:29,080 --> 00:26:32,280 Speaker 1: is not. It's tumbling, right, it's long and thin, but 511 00:26:32,320 --> 00:26:35,400 Speaker 1: it's tumbling like a you know, a tennis racket head 512 00:26:35,440 --> 00:26:39,119 Speaker 1: over heels, right, it's um it's it's tumbling around a 513 00:26:39,160 --> 00:26:41,760 Speaker 1: short axis. So that's not the kind of spaceship you 514 00:26:41,760 --> 00:26:43,720 Speaker 1: want to ride in. There's like a fun spaceship for 515 00:26:43,760 --> 00:26:48,439 Speaker 1: the hidians, you know, about five seconds and until you 516 00:26:48,480 --> 00:26:51,160 Speaker 1: start vomiting in space, which I don't think it's very fun. 517 00:26:51,640 --> 00:26:52,920 Speaker 1: Well you don't need you never know what A and 518 00:26:53,000 --> 00:26:56,800 Speaker 1: he's are into. You know. Maybe that's now you're right. 519 00:26:56,840 --> 00:26:59,080 Speaker 1: I'm always saying we should broaden our minds and so 520 00:26:59,200 --> 00:27:01,800 Speaker 1: what aliens might be like, and so yeah, maybe aliens 521 00:27:01,840 --> 00:27:04,159 Speaker 1: enjoy vomiting. I think you might be right there. So 522 00:27:04,200 --> 00:27:07,520 Speaker 1: the way you could tell a shape by the way 523 00:27:07,560 --> 00:27:09,639 Speaker 1: the light, even though it looks like a pinpoint, the 524 00:27:09,680 --> 00:27:12,520 Speaker 1: way that light from that pinpoint was changing sort of 525 00:27:12,520 --> 00:27:15,040 Speaker 1: told you that it was there was something in it 526 00:27:15,359 --> 00:27:18,040 Speaker 1: spinning and it was roughly the shape. Yeah, And if 527 00:27:18,080 --> 00:27:20,760 Speaker 1: something was spherical and it was spinning, then it wouldn't 528 00:27:20,800 --> 00:27:23,679 Speaker 1: be changing its apparent shape to us, right, But if 529 00:27:23,680 --> 00:27:26,440 Speaker 1: it's spinning or tumbling it has a long shape, then 530 00:27:26,720 --> 00:27:29,720 Speaker 1: the part that reflects light keeps changing, right, and so 531 00:27:29,840 --> 00:27:31,720 Speaker 1: you see more or less and more or less. And 532 00:27:31,720 --> 00:27:33,919 Speaker 1: that's how they made these estimates. A lot of really 533 00:27:33,920 --> 00:27:37,119 Speaker 1: good science went into extracting all this information out of 534 00:27:37,119 --> 00:27:41,240 Speaker 1: a very small amount of data. Wow, it seems almost fantastical, 535 00:27:41,720 --> 00:27:44,679 Speaker 1: like an artist rendition. But you're saying, like if it 536 00:27:44,720 --> 00:27:47,760 Speaker 1: was a death star or circular, it would not the 537 00:27:47,960 --> 00:27:51,159 Speaker 1: life from it wouldn't be it wouldn't vary. Yeah, exactly, 538 00:27:51,200 --> 00:27:54,800 Speaker 1: it wouldn't vary. And so it's tumbling, which is odd also, 539 00:27:55,240 --> 00:27:57,440 Speaker 1: but also the fact that it's so long and thin 540 00:27:57,520 --> 00:27:59,840 Speaker 1: as unusual. I mean, we look around at the population 541 00:27:59,840 --> 00:28:02,320 Speaker 1: of rocks in our solar system. You don't see rocks 542 00:28:02,359 --> 00:28:06,080 Speaker 1: like that, Like, you know, rocks are mostly spherical because 543 00:28:06,080 --> 00:28:09,000 Speaker 1: of gravity and collisions and stuff like that. Sometimes they 544 00:28:09,000 --> 00:28:11,880 Speaker 1: get longer and thinner. But like maybe three to one 545 00:28:12,040 --> 00:28:15,240 Speaker 1: or five to one, ten to one for a link 546 00:28:15,280 --> 00:28:18,600 Speaker 1: to with ratio is really weird, okay, And there's other 547 00:28:18,760 --> 00:28:21,240 Speaker 1: weird things about it, not just the shape, not just 548 00:28:21,280 --> 00:28:24,920 Speaker 1: to be, not just the direction it was going. There's 549 00:28:24,960 --> 00:28:27,800 Speaker 1: like these mysteries just keep compounding, Like we haven't even 550 00:28:27,840 --> 00:28:31,320 Speaker 1: talked about the craziest one. It gets crazier, all right, 551 00:28:31,840 --> 00:28:34,560 Speaker 1: gets so much crazier. Yeah, let's talk about that a 552 00:28:34,560 --> 00:28:50,800 Speaker 1: little bit more. But first quick break, what's the next one? 553 00:28:50,840 --> 00:28:54,040 Speaker 1: It's a very shiny apparently, Yeah, it's really really shiny. 554 00:28:54,080 --> 00:28:56,560 Speaker 1: We're like, what is it? You know, we don't know 555 00:28:56,560 --> 00:28:58,880 Speaker 1: what this thing is made out of? Um, but based 556 00:28:58,880 --> 00:29:00,680 Speaker 1: on its size and it's it's cetera, we know that 557 00:29:00,720 --> 00:29:04,440 Speaker 1: it's like ten times shinier than anything in any of 558 00:29:04,480 --> 00:29:07,320 Speaker 1: our asteroids, you know, like, what is this thing? It's 559 00:29:07,400 --> 00:29:10,240 Speaker 1: so bright, it reflects lights so much. We don't know 560 00:29:10,280 --> 00:29:11,720 Speaker 1: what it's made out of. It. That's the only clue 561 00:29:11,720 --> 00:29:14,320 Speaker 1: we have is that it's super shiny. Our asteroids are 562 00:29:14,360 --> 00:29:16,880 Speaker 1: sort of mostly like dark gray, right, Like, yeah, I 563 00:29:16,880 --> 00:29:19,120 Speaker 1: think they're they're gray or red based on how much 564 00:29:19,120 --> 00:29:21,200 Speaker 1: iron or whatever they have in them. But this was 565 00:29:21,240 --> 00:29:26,840 Speaker 1: a ten times shinier. So it's like a giant, gleaming, gleaming, silver, sparkling, 566 00:29:28,600 --> 00:29:32,400 Speaker 1: shiny unicorn horn flying through space. I know it makes 567 00:29:32,400 --> 00:29:34,320 Speaker 1: you wonder, like it gives you the image of a 568 00:29:34,400 --> 00:29:38,960 Speaker 1: sparkling spaceship, right, um, so you gotta wonder, um and 569 00:29:39,120 --> 00:29:41,520 Speaker 1: the thing that makes you think, wow, maybe this thing 570 00:29:41,560 --> 00:29:44,840 Speaker 1: could be a spaceship is that as it passed through 571 00:29:44,840 --> 00:29:46,880 Speaker 1: our solar system. So here's the weirdest thing. As it 572 00:29:46,880 --> 00:29:49,440 Speaker 1: passed through our solar system, we can track its motion 573 00:29:49,600 --> 00:29:51,880 Speaker 1: and we can predict its motion based on gravity. Right, 574 00:29:52,080 --> 00:29:54,520 Speaker 1: if something is just falling through gravity, we can tell 575 00:29:54,560 --> 00:29:57,360 Speaker 1: how it's going to go. But it didn't follow that path. 576 00:29:57,600 --> 00:30:00,400 Speaker 1: It looks like as it went through our solar system 577 00:30:00,400 --> 00:30:05,240 Speaker 1: it accelerated. What Yeah, they hit the gas. It hit 578 00:30:05,320 --> 00:30:08,320 Speaker 1: the gas. Yeah, it came into our solar system and 579 00:30:08,360 --> 00:30:10,600 Speaker 1: on its way out it floored it. It's like the 580 00:30:10,640 --> 00:30:13,520 Speaker 1: freight train was going through your town and then and 581 00:30:13,600 --> 00:30:15,880 Speaker 1: then it was thinking. The conductor was thinking, oh no, 582 00:30:15,960 --> 00:30:20,200 Speaker 1: I'm not gonna stop here for sure, this crap hole. 583 00:30:20,680 --> 00:30:23,280 Speaker 1: I'm just just gonna I'm just gonna, you know, step 584 00:30:23,280 --> 00:30:26,040 Speaker 1: on the accelerator. Yeah, it's like, let's get out of 585 00:30:26,040 --> 00:30:29,160 Speaker 1: town quick. Let's not exaggerate. It's already super weird. It 586 00:30:29,280 --> 00:30:32,480 Speaker 1: definitely accelerated. It didn't like double its speed. It's a 587 00:30:32,520 --> 00:30:35,400 Speaker 1: small effect, but it's definitely there. Definitely happened. Like we 588 00:30:35,440 --> 00:30:38,360 Speaker 1: can measure it precisely enough to say that there was 589 00:30:38,400 --> 00:30:41,040 Speaker 1: some acceleration and it wasn't just due to the sun 590 00:30:41,240 --> 00:30:43,600 Speaker 1: or it wasn't like the Sun was pulling on it 591 00:30:43,720 --> 00:30:45,719 Speaker 1: or anything. Well, the Sun was pulling on it, right, 592 00:30:45,800 --> 00:30:48,360 Speaker 1: that's the gravitational force, but it moved in a way 593 00:30:48,520 --> 00:30:50,920 Speaker 1: that required something else to explain it. It It requires the 594 00:30:50,920 --> 00:30:54,440 Speaker 1: Sun's gravity plus an extra push. And that's the question. 595 00:30:54,480 --> 00:30:58,520 Speaker 1: Where did that push come from? What what force did 596 00:30:58,520 --> 00:31:02,360 Speaker 1: it use to accelerate? Yeah, exactly. And so before you 597 00:31:02,400 --> 00:31:04,240 Speaker 1: go to like, well, there must have been an engine 598 00:31:04,280 --> 00:31:06,080 Speaker 1: on it and it was, you know, hitting the gas 599 00:31:06,080 --> 00:31:09,160 Speaker 1: on the way out, there are some other possible explanations 600 00:31:09,200 --> 00:31:12,360 Speaker 1: like maybe it has ice on it, and when it 601 00:31:12,360 --> 00:31:15,640 Speaker 1: came through the Solar system, that ice was melted, and 602 00:31:15,640 --> 00:31:18,040 Speaker 1: that ice like it shoots out and forms a gas 603 00:31:18,080 --> 00:31:20,719 Speaker 1: and basically forms like a tail like a comet, and 604 00:31:20,760 --> 00:31:22,840 Speaker 1: that can give it a push like a rocket like 605 00:31:22,880 --> 00:31:26,560 Speaker 1: it was. Yeah, but a natural rocket, not like you know, 606 00:31:26,600 --> 00:31:30,080 Speaker 1: an engine fabricated in another solar system. It could just 607 00:31:30,120 --> 00:31:31,880 Speaker 1: be like a block of ice on one side that's 608 00:31:31,880 --> 00:31:33,920 Speaker 1: got turned into gas and that's how a rocket would 609 00:31:33,960 --> 00:31:36,160 Speaker 1: work out. But they didn't see this gas, right, Yeah, 610 00:31:36,200 --> 00:31:38,520 Speaker 1: they looked at it really carefully, and the thing has 611 00:31:38,560 --> 00:31:41,000 Speaker 1: no gas around it, there's no tail, so there's no 612 00:31:41,080 --> 00:31:44,360 Speaker 1: evidence of any ice turning into gas or anything like that, 613 00:31:44,440 --> 00:31:48,400 Speaker 1: so we still don't understand it. Wow. Okay, So in 614 00:31:48,480 --> 00:31:51,240 Speaker 1: case people missed it, this thing flew by our into 615 00:31:51,240 --> 00:31:54,320 Speaker 1: our solar system and very close to the Earth. Yeah, 616 00:31:54,360 --> 00:32:00,640 Speaker 1: exactly end of this weirdly shaved you know two asked 617 00:32:00,800 --> 00:32:06,440 Speaker 1: accelerating shiny, strangely shaped object that we should never have seen. 618 00:32:06,920 --> 00:32:11,160 Speaker 1: That is almost impossible for it to exist. Um, just 619 00:32:12,000 --> 00:32:14,760 Speaker 1: went by our planet. It came by, it checked us out, 620 00:32:14,840 --> 00:32:18,320 Speaker 1: and it hit the gas on the way out. And 621 00:32:18,320 --> 00:32:19,960 Speaker 1: and you know, you might wonder, like, what are the 622 00:32:19,960 --> 00:32:24,000 Speaker 1: other explanations for it accelerating? Yeah, like what's what's the 623 00:32:24,000 --> 00:32:27,480 Speaker 1: most likely explanation? We don't have a most likely explanation. 624 00:32:27,720 --> 00:32:32,600 Speaker 1: Another plausible one is maybe it's really big and flat. Right. 625 00:32:32,640 --> 00:32:34,640 Speaker 1: If it's big and flat, then it can act like 626 00:32:34,680 --> 00:32:37,680 Speaker 1: a sail. It can catch sort of the Sun's radiation 627 00:32:38,000 --> 00:32:40,040 Speaker 1: and act like a sail in space. It's called a 628 00:32:40,080 --> 00:32:44,320 Speaker 1: solar sail. It basically catches the solar wind. So one 629 00:32:44,360 --> 00:32:48,840 Speaker 1: explanation for the speed, right, but none the acceleration. It 630 00:32:48,880 --> 00:32:51,479 Speaker 1: doesn't explain all those other things. It doesn't explain all 631 00:32:51,480 --> 00:32:54,240 Speaker 1: those other things. But it could explain the acceleration. On 632 00:32:54,280 --> 00:32:56,760 Speaker 1: the other hand, if you're thinking, well, big and flat, 633 00:32:56,840 --> 00:32:59,320 Speaker 1: that's pretty weird for a rock, right, Yeah, it is 634 00:32:59,360 --> 00:33:02,360 Speaker 1: pretty weird for a rock. Nature doesn't make big flat 635 00:33:02,440 --> 00:33:05,600 Speaker 1: sheets of material very often, right, You don't see those 636 00:33:05,600 --> 00:33:09,080 Speaker 1: in our solar system. What makes that, well, civilizations, Right, 637 00:33:09,440 --> 00:33:12,600 Speaker 1: So it's fantastic to think about. Maybe this is a 638 00:33:12,640 --> 00:33:16,640 Speaker 1: piece of alien junk. Right, Maybe this is like space archaeology. 639 00:33:17,040 --> 00:33:19,520 Speaker 1: Some ship blew up in a war somewhere a billion 640 00:33:19,600 --> 00:33:21,480 Speaker 1: years ago, and this is just like a hunk of 641 00:33:21,480 --> 00:33:25,880 Speaker 1: it flying through space with some sort of rocket attached 642 00:33:25,920 --> 00:33:28,040 Speaker 1: to it. No, it could just be a big flat 643 00:33:28,080 --> 00:33:30,680 Speaker 1: sheet of metal and it gets a little boost from 644 00:33:30,760 --> 00:33:33,560 Speaker 1: the solar wind as it passes through, and that's why 645 00:33:33,640 --> 00:33:37,120 Speaker 1: it's not just moving gravitationally. The acceleration could be explained 646 00:33:37,160 --> 00:33:39,480 Speaker 1: it just if it had that shape. On the other hand, 647 00:33:39,960 --> 00:33:42,960 Speaker 1: it could have been a purposely designed solar sale, right, 648 00:33:43,280 --> 00:33:45,200 Speaker 1: that's a way to get around the galaxy. Build these 649 00:33:45,240 --> 00:33:47,320 Speaker 1: sales and go from star to star and get a 650 00:33:47,360 --> 00:33:49,440 Speaker 1: little push as you go by each one. Or you 651 00:33:49,480 --> 00:33:52,960 Speaker 1: made me think of it was like a Shinese silver surfboard, 652 00:33:53,240 --> 00:34:05,400 Speaker 1: like silver surfer Yeah, exactly, It's fascinating to think of 653 00:34:05,480 --> 00:34:07,520 Speaker 1: all the ways that this thing is weird, and all 654 00:34:07,560 --> 00:34:10,160 Speaker 1: the possible explanations that we we sort of hope for, 655 00:34:10,360 --> 00:34:13,239 Speaker 1: right the ones we want, the stories we'd like to tell. 656 00:34:13,840 --> 00:34:15,680 Speaker 1: And the thing I love about this object is that 657 00:34:15,719 --> 00:34:18,880 Speaker 1: it resists conventional explanation. You try to come up with 658 00:34:18,880 --> 00:34:21,160 Speaker 1: some explanation you think makes sense. No, well, how do 659 00:34:21,200 --> 00:34:23,040 Speaker 1: you explain this? And how do you explain that it's 660 00:34:23,080 --> 00:34:26,600 Speaker 1: got so many different ways of being weird? Which could 661 00:34:26,640 --> 00:34:29,520 Speaker 1: mean either it's just kind of like a miracle, like 662 00:34:29,560 --> 00:34:33,799 Speaker 1: this crazy unlikely event that happened, or maybe our view 663 00:34:33,840 --> 00:34:38,279 Speaker 1: of the universe is totally wrong, and maybe maybe um, 664 00:34:38,320 --> 00:34:40,080 Speaker 1: we got it all wrong and it's not that rare 665 00:34:40,280 --> 00:34:43,200 Speaker 1: for this to happen exactly. So either it's a rare 666 00:34:43,239 --> 00:34:45,759 Speaker 1: event and you know, we're just sort of lucky afternomically 667 00:34:45,800 --> 00:34:48,239 Speaker 1: to get to see it, or as you say, it's 668 00:34:48,320 --> 00:34:50,560 Speaker 1: less rare than we expect and maybe we'll see more 669 00:34:50,600 --> 00:34:53,960 Speaker 1: of them, right, that would be pretty cool. Um, Or 670 00:34:54,000 --> 00:34:57,560 Speaker 1: it's not a natural phenomenon, right, maybe it is aliens. Right, 671 00:34:57,600 --> 00:35:00,640 Speaker 1: we can't rule that out, but in any case, it's 672 00:35:00,719 --> 00:35:03,960 Speaker 1: gone right, it's it went by already it's gone if 673 00:35:04,000 --> 00:35:07,080 Speaker 1: you wanted to know more about it too late, Yes, 674 00:35:07,239 --> 00:35:09,000 Speaker 1: it's gone, but it's not too late to learn more 675 00:35:09,000 --> 00:35:12,319 Speaker 1: about it. I mean we could potentially build like a 676 00:35:12,320 --> 00:35:15,280 Speaker 1: fast rocket that takes a slingshot around Jupiter and zooms 677 00:35:15,280 --> 00:35:18,799 Speaker 1: out there or something a long time to catch up. Yeah, 678 00:35:18,960 --> 00:35:20,840 Speaker 1: it would take a long time to catch up to it, 679 00:35:21,760 --> 00:35:23,160 Speaker 1: and by the time it did, it would be like 680 00:35:23,160 --> 00:35:25,480 Speaker 1: twenty years before it got there and sent us pictures 681 00:35:25,520 --> 00:35:27,799 Speaker 1: back and stuff. Who knows if we even have a 682 00:35:27,840 --> 00:35:30,319 Speaker 1: society in twenty years, right, I send data back to 683 00:35:30,360 --> 00:35:33,400 Speaker 1: the smoking rubble of Western civilization. That's a that's a 684 00:35:33,480 --> 00:35:36,359 Speaker 1: cheery thought, right. The better opportunity is just to build 685 00:35:36,360 --> 00:35:39,400 Speaker 1: a bigger telescope, oh to see it. But isn't it 686 00:35:39,440 --> 00:35:42,600 Speaker 1: too late? Isn't already sort of? I mean it's leaving 687 00:35:42,640 --> 00:35:46,239 Speaker 1: a twenty six kilometers per second? Yeah, But fortunately we've 688 00:35:46,280 --> 00:35:49,479 Speaker 1: been building a really awesome new telescope for the last 689 00:35:49,560 --> 00:35:51,399 Speaker 1: I don't know, en years, and it's going to turn 690 00:35:51,440 --> 00:35:54,400 Speaker 1: on in a few years. It's called the Large Synoptics 691 00:35:54,400 --> 00:35:56,840 Speaker 1: Survey Telescope, and it's going to be pretty awesome, and 692 00:35:56,840 --> 00:35:58,920 Speaker 1: it's going to turn on in about three years and 693 00:35:58,960 --> 00:36:00,759 Speaker 1: when it does, it's going to give us pictures like 694 00:36:00,880 --> 00:36:04,759 Speaker 1: nothing's ever seen before. And um, and it might be 695 00:36:04,800 --> 00:36:07,040 Speaker 1: able to give us good pictures of this crazy thing. 696 00:36:08,000 --> 00:36:09,799 Speaker 1: But wouldn't it have been better to look at it 697 00:36:09,800 --> 00:36:12,839 Speaker 1: when it was going through the Solar system? You know, 698 00:36:12,880 --> 00:36:16,759 Speaker 1: I get a good look that. Um. Yes, it would 699 00:36:16,760 --> 00:36:18,680 Speaker 1: have been um. But we didn't know it was coming, 700 00:36:18,760 --> 00:36:21,960 Speaker 1: so we weren't prepared. We were lucky we even saw it. 701 00:36:21,960 --> 00:36:25,440 Speaker 1: It was a short notice, yeah, exactly. Um, you know 702 00:36:25,480 --> 00:36:27,960 Speaker 1: we saw it when it was already like deep into 703 00:36:28,000 --> 00:36:29,440 Speaker 1: our solar system. It's not the kind of thing we 704 00:36:29,440 --> 00:36:31,920 Speaker 1: were looking for, right. Nobody sets out to find these 705 00:36:31,920 --> 00:36:34,160 Speaker 1: things because you expect them to never come. Well, that 706 00:36:34,280 --> 00:36:36,640 Speaker 1: just kind of tells you that on a daily basis, 707 00:36:36,680 --> 00:36:40,520 Speaker 1: like we are still seeing things about the universe that 708 00:36:40,600 --> 00:36:44,480 Speaker 1: are completely inexplicable, exactly. And that's what I love about 709 00:36:44,520 --> 00:36:47,719 Speaker 1: astronomy and space physics that almost every time we look 710 00:36:47,760 --> 00:36:51,279 Speaker 1: out there in the cosmos, we see something crazy. Right, 711 00:36:51,320 --> 00:36:54,399 Speaker 1: It's full of surprises. There's so many things out there 712 00:36:54,640 --> 00:36:56,320 Speaker 1: which if we could see them or learn them, or 713 00:36:56,360 --> 00:36:59,120 Speaker 1: if they visited us, would blow our minds with the 714 00:36:59,160 --> 00:37:02,080 Speaker 1: way they change perspective about our lives and the universe 715 00:37:02,080 --> 00:37:05,680 Speaker 1: and how everything works. Well, if you're an alien writing 716 00:37:05,680 --> 00:37:09,560 Speaker 1: on and you're listening to this podcast, we just want 717 00:37:09,560 --> 00:37:14,480 Speaker 1: to say hello, Thanks for visiting.

Thanks for not 719 00:37:18,719 --> 00:37:22,080 Speaker 1: sucking our brains out of our newses see you later, 720 00:37:23,960 --> 00:37:34,440 Speaker 1: Thanks for listening everyone, see you next time. If you 721 00:37:34,520 --> 00:37:37,359 Speaker 1: still have a question after listening to all these explanations, 722 00:37:37,480 --> 00:37:40,440 Speaker 1: please drop us a line.
