What Was Oumuamua? · Daniel and Kelly’s Extraordinary Universe

0:05
Speaker 1: Hey, Daniel, do you ever think about what it would
0:07
Speaker 1: be like if we were visited by aliens? Oh? My god,
0:11
Speaker 1: I think about that all the time. Do you really
0:14
Speaker 1: what do you think would happen? Well, in my imagination,
0:16
Speaker 1: it always starts the same way. There's some sleepy guy
0:19
Speaker 1: in front of a terminal somewhere which starts to blink
0:21
Speaker 1: and then annoy him and wake him up, and he
0:23
Speaker 1: looks it up and he rubs his face and he goes, hmmm,
0:26
Speaker 1: that's weird. Isn't that what happens in like every single
0:30
Speaker 1: science witchian movie ever? Exactly? Um? And you know the
0:34
Speaker 1: cool thing is that it's actually happened a few times
0:37
Speaker 1: in real life. Yeah, that's right. Didn't happen just last year? Yeah,
0:40
Speaker 1: it happened last year. It also happened in the seventies
0:42
Speaker 1: when we got a weird signal from space called the
0:44
Speaker 1: Wow signal. So sometimes we do we see weird things
0:49
Speaker 1: coming at us from space. But it happened as recently
0:51
Speaker 1: as last year. That's right, last year. Was it aliens?
0:55
Speaker 1: We still don't know. We do know that it was weird,
0:58
Speaker 1: how weird? Unquantifiably weird? Was it? Um? I'm a little weird.
1:07
Speaker 1: It was more weird than you think. That's what I
1:12
Speaker 1: was looking for. Hi, I'm and I'm Daniel, and welcome
1:31
Speaker 1: to our podcast. Daniel and Jorge explain the universe, in
1:35
Speaker 1: which we try to take everything in the universe, including
1:38
Speaker 1: weird things from outer space, and explain them to you,
1:41
Speaker 1: even if they're inexplicable. That's right, even those unwanted visitors.
1:46
Speaker 1: What do you mean unwanted? I want a visitor, You
1:48
Speaker 1: want a visitor. Yeah, Aliens, come on down here. Tell
1:51
Speaker 1: us all about how the rest of the galaxy works.
1:54
Speaker 1: Tell us about the rest of the universe. We need
1:56
Speaker 1: some more data. I'm dying to know what's going on
1:58
Speaker 1: out there, aren't you? And slaves ITAs, You're so cynical. No,
2:03
Speaker 1: it's very likely if aliens arived that they will just
2:05
Speaker 1: take over and suck our brains out of our noses.
2:07
Speaker 1: But in the inter the short intermission before that happens,
2:11
Speaker 1: they might grant us some knowledge about the universe. And
2:13
Speaker 1: you know that could be worth it. You would trade it.
2:15
Speaker 1: You would be like, um, all yours, but first tell
2:18
Speaker 1: me what's up with Pie? You know, if I could
2:21
Speaker 1: have absolute knowledge of everything in the universe, Yeah, I
2:24
Speaker 1: might uh, I might be willing to sacrifice my brain
2:27
Speaker 1: for that. You're like, before you make me into a pie,
2:31
Speaker 1: please explain pie to me. That's right, exactly. Well, today
2:36
Speaker 1: on the podcast, we are going to talk about a
2:38
Speaker 1: visitor to our solar system, one that not not a
2:42
Speaker 1: single scientist can really explain. That's right. Last year of actually,
2:47
Speaker 1: a strange object passed through our solar systems from somewhere
2:52
Speaker 1: very far away, somewhere unknown, and there's a lot of
2:55
Speaker 1: weird things about it, things that we can't quite explain.
2:58
Speaker 1: So it's the opportunity to learn something about other parts
3:01
Speaker 1: of the universe. It's a very suspicious object, right, Yeah,
3:04
Speaker 1: I don't think you need to view it with suspicion.
3:06
Speaker 1: I mean it's strange, it's unusual, it's weird. We don't
3:09
Speaker 1: understand it. But I see as an opportunity. I mean,
3:12
Speaker 1: it's like we've been looking out into the stars for
3:15
Speaker 1: decades trying to learn about the rest of the universe
3:17
Speaker 1: just by looking, Right, wouldn't it be awesome if some
3:20
Speaker 1: of the rest of the universe came to us so
3:22
Speaker 1: we could just like, you know, hold it and play
3:24
Speaker 1: with it. Like the same reason we want to get
3:26
Speaker 1: rocks from the Moon and rocks from Mars. Wouldn't you
3:28
Speaker 1: love rocks from alien planets and other galaxies or other
3:32
Speaker 1: solar systems. Yeah, so you're saying it's it's more like
3:34
Speaker 1: conspicuous rather than suspicious. That's right. Yeah, it's um. It's
3:40
Speaker 1: conspicuously suspicious or suspiciously conspicuous and probably not omniscient. Um.
3:48
Speaker 1: But it hasn't answered any of our questions yet. So
3:50
Speaker 1: we have a lot of questions about this weird rock
3:53
Speaker 1: from outer space. That's right. Today on the podcast we'll
3:56
Speaker 1: be talking about what is it, Where did it come from,
4:06
Speaker 1: Where where is it going? Why did it stop by
4:09
Speaker 1: our solar system? Isn't it Hawaiian? Maybe just like Hawaiian pizza?
4:13
Speaker 1: I don't know. You know, the name comes from a
4:17
Speaker 1: word in the Hawaiian language, right, Mua means scout or
4:21
Speaker 1: like distant messenger or something. It's sort of a funny name.
4:24
Speaker 1: But be careful how you pronounce it because it's it's
4:27
Speaker 1: starts out with a letter that's not really a letter.
4:30
Speaker 1: It's like this, um, you write it as an apostrophe.
4:33
Speaker 1: It's a glottal stop. So I'm not even sure how
4:35
Speaker 1: officially to pronounce this thing. So not only is the
4:38
Speaker 1: rock weird, but the word for the rock is like
4:41
Speaker 1: difficult to understand. We should do a whole podcast on
4:44
Speaker 1: glottal stops on who names these things? Anyway, it's sort
4:50
Speaker 1: of a noble name. It's supposed to be a noble name.
4:52
Speaker 1: Like it's sort of like a like an explorer of
4:54
Speaker 1: the stars, right, yeah, exactly, So it's got that positive
4:58
Speaker 1: light on. It's not like invade or and destroyer of
5:01
Speaker 1: worlds or anything. Yeah, although scout that that makes me
5:04
Speaker 1: think of like an advanced count, you know, like a reconnaissance.
5:08
Speaker 1: Are you worried that aliens are gonna invade and eat you? Um? Yes?
5:15
Speaker 1: Um so yes. So this weird rock Omumu appeared in
5:19
Speaker 1: seventeen and we are still struggling to understand it, where
5:22
Speaker 1: it came from, what it was wise visited us, what
5:24
Speaker 1: it means, you know, was it artificial, was it natural?
5:27
Speaker 1: We still don't really know. Um And so we thought
5:30
Speaker 1: let's dig into it on this podcast and tell you
5:32
Speaker 1: all about how it's strange and how it's interesting and
5:34
Speaker 1: all the mysteries that still remain about this weird rock. Yeah,
5:38
Speaker 1: it was in the news a lot last year, right, yeah,
5:41
Speaker 1: because it it passed through and really made waves in
5:44
Speaker 1: the astronomical community. People were like amazed to see this
5:47
Speaker 1: kind of thing. We were wondering how far these waves
5:50
Speaker 1: in the astronomical community made their way into the general public.
5:54
Speaker 1: How many people out there have heard of or knew
5:58
Speaker 1: what is momma? Yeah? Was it only astronomers, was it
6:02
Speaker 1: astronomers plus everybody interested in alien visitation? Or was it
6:06
Speaker 1: everybody on earth that was captivated by the passage of
6:09
Speaker 1: this strange rock. We were curious. I just want to
6:12
Speaker 1: know how many people can pronounce it or spell it?
6:16
Speaker 1: That's zero. I already know the answer to that. So
6:19
Speaker 1: as usual, Daniel went out there and asked people in
6:22
Speaker 1: the street what was MoMA? Yeah? I asked them have
6:26
Speaker 1: you heard of omamua? And if they answered yes, I
6:29
Speaker 1: also asked them what they thought it was. Well, here's
6:33
Speaker 1: what people had to say. No, okay, no, I'm not
6:38
Speaker 1: I'm sorry, I'm not her. Yeah I did not okay,
6:42
Speaker 1: no I never heard of it? No all right, no, no, no, okay, yes,
6:49
Speaker 1: what do you think? It is? Probably just some kind
6:52
Speaker 1: of space debris. I did not hear about that, Okay,
6:55
Speaker 1: I just what do you think it was probably some
6:58
Speaker 1: kind of meteor. I just think it was like a
7:01
Speaker 1: like a meteor off. Okay, No, I did not know. Okay, alright,
7:05
Speaker 1: So about like fifty fifty half of the people seem
7:07
Speaker 1: to know or have heard about it, and have the
7:11
Speaker 1: people had no idea? I never heard of it. Yes,
7:13
Speaker 1: what do you think of the Astronomy Communities pr PR machine?
7:17
Speaker 1: Apparently it must be better than the aliens PR machinery,
7:22
Speaker 1: But don't don't you think they could have done mua
7:24
Speaker 1: mua with it? I think we should stop with the
7:35
Speaker 1: all right, that officially ends them puns. Yeah, most people
7:38
Speaker 1: had never even heard of this thing, which to me
7:40
Speaker 1: boggles the mind, Like what an incredible event to happen,
7:43
Speaker 1: and just for people to be unaware of it, you
7:45
Speaker 1: know it all the newspapers and people were talking about it.
7:47
Speaker 1: How could you just go through your normal life and
7:49
Speaker 1: not know that there's a potential alien ship flying through
7:53
Speaker 1: the Solar System? Right? I feel like maybe people are jaded,
7:56
Speaker 1: you know, when they see an headline it goes put
7:58
Speaker 1: possible alien visiting the Solar System. People just I don't
8:03
Speaker 1: know these days, it's all it's just kind of all
8:06
Speaker 1: part of the noise it goes through people's feeds. You mean,
8:08
Speaker 1: because the world is so crazy that doesn't seem so
8:10
Speaker 1: crazy anymore, or because you see that kind of headline
8:13
Speaker 1: pretty often. Well, I think it's because, um, like the
8:17
Speaker 1: headline itself sounds huge, but it's not like on the
8:20
Speaker 1: front page of newspapers or website, do you know what
8:24
Speaker 1: I mean? Like it it sounds like it should be
8:26
Speaker 1: a huge deal, but you know, obviously people are not
8:28
Speaker 1: freaking out about it. So you know, I think as
8:31
Speaker 1: as news consumers, you just assume that it's hyperbole or
8:34
Speaker 1: clickbait or something. Oh, I see everybody's lying, so everything
8:37
Speaker 1: must be a lie. Right, Yeah, that's a bummer. So
8:40
Speaker 1: when aliens, when aliens actually land, you're gonna be like whatever,
8:43
Speaker 1: you're just clickbait, go away. Well, I mean, it's not
8:45
Speaker 1: on the front page, right, Like, it's not you know,
8:47
Speaker 1: it's not dominating the conversation. It's hard for me to
8:50
Speaker 1: remember because I obviously pay attention to the scientific news,
8:53
Speaker 1: maybe more than the average person. To me, it was
8:55
Speaker 1: in the front of my brain for for a long time. Um,
8:58
Speaker 1: but yeah, maybe for the averag person it was just
9:01
Speaker 1: you know, a minor interesting thing that astronomers saw. Well,
9:06
Speaker 1: let's break it down for people. Um, so what was
9:08
Speaker 1: this thing called. So this is a thing that was
9:11
Speaker 1: seen by a telescope in Hawaii. It's called the Pan
9:14
Speaker 1: Stars telescope, and it basically just turned on. Is this
9:18
Speaker 1: gorgeous new telescope and they're supposed to be looking deep
9:21
Speaker 1: into outer space and understanding how the how the cosmos
9:26
Speaker 1: that are evolving, and how supernova are exploding and all
9:29
Speaker 1: that's kind of fascinating astronomical and cosmological questions. What makes
9:33
Speaker 1: that telescope gorgeous? It can see really far into the past,
9:36
Speaker 1: and so to me, that's just gorgeous. Like every time
9:39
Speaker 1: we open our eyes in a new way or open
9:41
Speaker 1: a new set of eyes, we see more of the universe,
9:44
Speaker 1: and the universe is beautiful. I mean that's purely subjective,
9:47
Speaker 1: but to me, when I look at in space, I
9:49
Speaker 1: see beauty, and so I love when we turn on
9:52
Speaker 1: new eyes and we can see new areas of the
9:54
Speaker 1: universe we've never seen before. And that's where the Pan
9:57
Speaker 1: Stars Telescope allowed us to do. Beautiful way to say it,
10:01
Speaker 1: And so they turned this thing on and pretty quickly
10:04
Speaker 1: they saw something weird. They saw this rock moving really
10:07
Speaker 1: really fast tom into our solar system, and you might think, well,
10:12
Speaker 1: there's a lot of rocks in the solar system, right,
10:14
Speaker 1: how can you tell that this one is weird? Or
10:16
Speaker 1: what's weird about this one? And the weird thing about
10:18
Speaker 1: this one where its direction and its speed? Wait, so
10:22
Speaker 1: why didn't other telescope see it? Why did it require
10:25
Speaker 1: this brand new, gorgeous telescope. Well, this is one of
10:27
Speaker 1: the more powerful telescopes we have. I think other telescopes
10:30
Speaker 1: could have seen it. There's also just a little bit
10:32
Speaker 1: of luck and who spotted it first. You happen to
10:34
Speaker 1: be looking in the right place, and also you happen
10:36
Speaker 1: to notice it. You know, a lot of times you
10:38
Speaker 1: turn on your telescope and you're looking for thing A
10:41
Speaker 1: and you accidentally discover thing B. But only if you're
10:44
Speaker 1: curious enough. Right, if you see something weird in your
10:47
Speaker 1: data and you're like, huh, I don't understand that, what
10:48
Speaker 1: could that be? You could just shrug and say I
10:51
Speaker 1: don't know whatever and move on with your life. Or
10:53
Speaker 1: you could follow it up and try to figure it out.
10:55
Speaker 1: And sometimes that's where the greatest discoveries are made. You know.
10:58
Speaker 1: That's how like Pluto was discovered it or that's how
11:00
Speaker 1: pulsars were discovered. All these things were accidents, is things.
11:04
Speaker 1: People saw something weird in their data. It didn't just
11:07
Speaker 1: blow off their curiosity. They followed it up, right. Yeah,
11:09
Speaker 1: that worked out really well for Pluto. I think Pluto's
11:15
Speaker 1: legal team is still fighting that battle. It's posthumous legal team.
11:20
Speaker 1: It's not dead. We didn't kill Pluto's still there, That's
11:24
Speaker 1: what the book says. So they turned on this telescope
11:32
Speaker 1: and they basically saw stars and things out there, and
11:36
Speaker 1: they saw one of them moving in a weird direction
11:39
Speaker 1: at weird speed. Yeah, and there's a lot of weird
11:41
Speaker 1: things out there. Right. We have planets in our Solar system.
11:44
Speaker 1: We have asteroids, we have we have a lot of asteroids.
11:47
Speaker 1: We even have comets, right, And commets move differently, but
11:50
Speaker 1: everything in the Solar System shares one feature, which is
11:53
Speaker 1: they're moving around the Sun. Right. They're gravitationally bound by
11:57
Speaker 1: the Sun. They're in a stable orbit. So even comets
12:00
Speaker 1: that come in every hundred years and then zoom out
12:02
Speaker 1: really far, they're still moving around the Sun right there there,
12:05
Speaker 1: and the focus of their orbit is the Sun. And
12:10
Speaker 1: this object was moving in a way that's totally inconsistent
12:13
Speaker 1: with being in an orbit around the Sun any orbit. Right,
12:17
Speaker 1: It was going way too fast in the wrong direction.
12:19
Speaker 1: You mean, we've never seen an asteroid or anything else.
12:23
Speaker 1: It wasn't revolving around our Sun. Is that what you're saying.
12:26
Speaker 1: That's exactly what I'm saying. We've never seen anything never.
12:29
Speaker 1: It wasn't gravitationally bound to the Sun. This is the
12:32
Speaker 1: first time we've seen something that looks like it came
12:34
Speaker 1: from another Sun. And we could tell just by the motion. Right,
12:38
Speaker 1: that's there's none from We'll talk later about what it
12:40
Speaker 1: looks like and how weird it is in the shape
12:42
Speaker 1: of it, but just from its motion, we could tell
12:45
Speaker 1: that it didn't come from our solar system because it
12:48
Speaker 1: was moving too fast or in a weird trajectory, or
12:51
Speaker 1: what do you mean both. It was moving in a
12:53
Speaker 1: trajectory that made it clear it was not going to
12:55
Speaker 1: stick around. Right. They saw it moving, and they could
12:58
Speaker 1: plot its speed and its direction, so they could tell
13:01
Speaker 1: where it was going to go, and they could tell
13:02
Speaker 1: it was just going to go right through our solar system.
13:05
Speaker 1: It wasn't moving around the Sun. So we could get
13:07
Speaker 1: lots of looks at it. It It was just going to
13:08
Speaker 1: pass through once, and how do we figure out how
13:11
Speaker 1: far it was? How do we figure out how far
13:14
Speaker 1: away it is? Um, that's a good question. You know.
13:17
Speaker 1: We did a whole episode about measuring distances to things,
13:20
Speaker 1: and so I think you can tell how far away
13:22
Speaker 1: things are using parallax seeing, you know, multiple measurements that
13:26
Speaker 1: that are spaced far apart, sort of the way your
13:28
Speaker 1: eyes work, and so within the solar system, I think
13:31
Speaker 1: that works pretty well because things aren't that far away.
13:33
Speaker 1: So you can tell how far away things are by
13:35
Speaker 1: saying how differently they look or how much they move
13:38
Speaker 1: from different viewpoints, So you multiple telescopes, or you look
13:41
Speaker 1: at the same thing over several days as the Earth
13:44
Speaker 1: is moving. That's a great question. I'm not sure, but
13:46
Speaker 1: that's how I would do it. And it wasn't just
13:49
Speaker 1: moving a little bit fast relative to our solar system.
13:53
Speaker 1: It was a moving something like twenty six kilometers per
13:56
Speaker 1: second faster than we were per second. Yeah, exactly, That's
14:01
Speaker 1: that's pretty fast. It's like, in a second, wish you
14:03
Speaker 1: just went twenty six kilometers. I wish I could go
14:05
Speaker 1: ko per second. You know, maybe Tesla's can do that.
14:08
Speaker 1: I don't know the too. What is it called the
14:11
Speaker 1: hyper exactly? It was basically hyperlooping through our solar system.
14:14
Speaker 1: Yeah yeah, it's fast, right, like it's um, nothing really
14:17
Speaker 1: moved that fast in our solar system. Um. Yeah, And
14:20
Speaker 1: even comets that approached the Sun they speed up really
14:22
Speaker 1: fast and then you'll go this fast right Yeah, so
14:24
Speaker 1: it was moving pretty quick. It's like seeing a freight
14:27
Speaker 1: freight train coming at in your direction really really fast,
14:30
Speaker 1: and you're like, Okay, that thing is not going to
14:32
Speaker 1: stop where I am. It's going so fast. Yeah, exactly,
14:36
Speaker 1: And fortunately it didn't pass too close to the Earth
14:38
Speaker 1: or unfortunately if you wanted us to get a better look.
14:41
Speaker 1: It passed within like fifteen million miles of the Earth. Wow,
14:44
Speaker 1: that sounds like a lot. Is that a lot? You know?
14:47
Speaker 1: It's um, it's a significant It's like, um, fifteen percent
14:51
Speaker 1: of the distance between the Earth and the Sun, so
14:53
Speaker 1: asteroids passed much closer all the time. Fifteen percent. So
14:58
Speaker 1: from here the Sun, it's a hundred million miles, million miles,
15:02
Speaker 1: million miles from here to the side. So it's it's
15:05
Speaker 1: pretty close. I mean, it's not like it went over
15:07
Speaker 1: our heads, like it came sort of into this solar system. Oh,
15:10
Speaker 1: it definitely went right through the solar system. Yeah. I
15:13
Speaker 1: think your freight train analogy is a perfect one. You know,
15:15
Speaker 1: you're in a house and you're here, this freight train
15:18
Speaker 1: rumbled by, and you're like, yesh, that was kind of
15:20
Speaker 1: loud and close and weird, and it definitely didn't stop
15:23
Speaker 1: in your town, right, just like blew right through like
15:25
Speaker 1: you weren't even there. That's frightening. Yeah, And and it's
15:30
Speaker 1: not even that big, you know, the thing is like
15:32
Speaker 1: it's we were not sure exactly because we don't have
15:34
Speaker 1: great pictures of it. It was moving so fast and
15:37
Speaker 1: it was so far away that we didn't that all
15:39
Speaker 1: of our telescopes just see it basically as a point
15:41
Speaker 1: of light. So we have some estimates for its size
15:44
Speaker 1: and its shape um based on you know, how we
15:47
Speaker 1: think it's rotating, etcetera. But the thing was not that big.
15:50
Speaker 1: Like the dimensions are like, you know, a few hundred
15:52
Speaker 1: meters in the longest dimension and like tens of meters
15:56
Speaker 1: or maybe a hundreds in the other. So we are
15:59
Speaker 1: lucky to even e this rock. You know, rocks can
16:01
Speaker 1: fly through our solar system without us noticing them if
16:03
Speaker 1: they don't like reflect light just the right moments so
16:06
Speaker 1: that we can see them from the sun, because these
16:08
Speaker 1: things don't glow right there dark unless they're reflecting light
16:11
Speaker 1: from the sun. I see. Wow. Okay, so let's talk
16:14
Speaker 1: about where it came from potentially or which from which
16:18
Speaker 1: direction it came, But first let's take a break. Okay,
16:34
Speaker 1: So I read that this object apparently came from Las Vegas.
16:39
Speaker 1: Is that that's right? It had a crazy night in Vegas.
16:43
Speaker 1: It has no explanation for why it's so weird, the
16:45
Speaker 1: home of rock and roll, right, so rocks that would
16:48
Speaker 1: make sense, and it just rolled on though our solar system. Yeah,
16:53
Speaker 1: um no, but you're close. It came from the direction
16:56
Speaker 1: of Vega, right. We can tell it's trajectory, and we
17:00
Speaker 1: um extrapolate back. We're like, oh, what's in that direction
17:02
Speaker 1: in the sky, and that the answer is Vega. Vega
17:05
Speaker 1: is kind of interesting because it's it's kind of a
17:06
Speaker 1: nearby star, right, think it's one among the sort of
17:10
Speaker 1: closer stars. Right. Yeah, but this thing, even traveling at
17:13
Speaker 1: its high speed, would take hundreds of thousands of years
17:16
Speaker 1: to get here from Vega. So it's close, you know,
17:20
Speaker 1: sort of on a galactic scale, but it's not really
17:22
Speaker 1: close on a you know, um, let's go out for
17:25
Speaker 1: dinner kind of scale. So it just sort of came
17:27
Speaker 1: from Vegas, from Vega, right, And again we don't know
17:30
Speaker 1: that it came from that system. It's just sort of
17:33
Speaker 1: answering the question what's in the sky in that direction?
17:35
Speaker 1: We can extrapolate back and say, oh, came that way,
17:38
Speaker 1: what else is there? But you know, Vega is in
17:40
Speaker 1: a different place a long time ago. Everything is rotating
17:43
Speaker 1: and moving and could have gone through that system also
17:46
Speaker 1: from another one. Right, we have no idea how long
17:48
Speaker 1: it's been bouncing around the galaxy. Right, and let's talk
17:51
Speaker 1: about kind of how big it was, because it's not
17:54
Speaker 1: like the size of Manhattan, right, Like it's it's more
17:56
Speaker 1: like the size of it's like the sky size of
17:58
Speaker 1: one skyscraper in Manhattan. It's like maybe up to a
18:02
Speaker 1: kilometer long and like, you know, fifty to a hundreds
18:06
Speaker 1: on each side, So it's it's about the size of
18:08
Speaker 1: a skyscraper. It's like the Empire State Building to zoom
18:12
Speaker 1: by exactly, or maybe it's the Las Vegas version. Isn't
18:16
Speaker 1: there one of those in Las Vegas. So somewhere between
18:20
Speaker 1: the Vegas empar Site building and the real Emparsity building
18:23
Speaker 1: was the size of this strange, mysterious object. Wouldn't that
18:27
Speaker 1: be amazing if we visited it and found that it
18:30
Speaker 1: had exactly the shape of the Empire State Building, that
18:32
Speaker 1: would be pretty odd. That would be more amazing. That
18:36
Speaker 1: would be a great twist ending to the science fiction
18:38
Speaker 1: movie Somebody's going to make about this thing, which started
18:41
Speaker 1: with a guy in a control room looking at a
18:43
Speaker 1: blinking light, going, that's weird. What's the Empire State Building
18:46
Speaker 1: doing there? It's supposed to be in Vegas. I mean
18:48
Speaker 1: it's not huge, but I mean it's not it's not
18:50
Speaker 1: like the size of the moon, or it's not the
18:52
Speaker 1: size of you know, the continent. It's like it's it's
18:56
Speaker 1: sort of like, well, how big you might imagine a
18:58
Speaker 1: spaceship to be. Yeah, exactly, it's a reasonable size for
19:01
Speaker 1: a spaceship, which led to a lot of speculation. Right,
19:04
Speaker 1: you might be thinking, all right, so it's a rock
19:07
Speaker 1: from another solar system. We got rocks, They got rocks.
19:09
Speaker 1: One of their rocks ended up in our backyard. What's
19:12
Speaker 1: the big deal? Right? But it's kind of a big
19:14
Speaker 1: deal because we don't expect to see this kind of rock.
19:17
Speaker 1: What do you mean in terms of its size or
19:20
Speaker 1: its speed or what. Well, these solar systems are really
19:23
Speaker 1: far apart, right, And yeah, we got a bunch of rocks,
19:26
Speaker 1: but most of those rocks are just sort of floating
19:28
Speaker 1: around our Sun, and occasionally one of them gets kicked
19:31
Speaker 1: off and floats away. But you know, to pass right
19:34
Speaker 1: through another solar system is just really small odds. The
19:37
Speaker 1: chances of the happening are tiny. Based on our understanding
19:40
Speaker 1: of how often the Sun sort of loses rocks and
19:43
Speaker 1: let them float into interstellar space, this should almost never happen, right,
19:48
Speaker 1: So it's like like a rock in our meteor belt.
19:52
Speaker 1: These are big rocks, but they hardly ever leave the
19:54
Speaker 1: Solar system, so it's weird that there would be one
19:58
Speaker 1: floating around randomly. That's right. And there are rocks in
20:01
Speaker 1: our asteroid belt. But there's also this big cloud of
20:04
Speaker 1: icy objects that forms comments called the Oort cloud o
20:08
Speaker 1: O r T, and it's a bunch of really loosely
20:11
Speaker 1: held objects from the Sun. And that's probably better candidates
20:13
Speaker 1: for how we might lose rocks. Um. And you know,
20:16
Speaker 1: they have models for how often does the Sun lose
20:18
Speaker 1: a rock, and so they can calculate if other suns
20:21
Speaker 1: are losing rocks about the same level, how often should
20:24
Speaker 1: we see one of these things? And you know they
20:26
Speaker 1: did the calculation and they're like, you know, if you
20:28
Speaker 1: turn on the pan star's telescope, what are the chances
20:31
Speaker 1: of seeing an extrasolar rock a rock from another solar system,
20:34
Speaker 1: like within the first few months, and the odds are
20:37
Speaker 1: like up to one in a hundred millions. You know,
20:39
Speaker 1: it's just not the kind of thing that happens very
20:41
Speaker 1: often because these other solar systems are far apart. Space
20:45
Speaker 1: is pretty empty. What I mean is you hardly have
20:49
Speaker 1: to worry about running into a rock if you're going
20:51
Speaker 1: between stars, Yeah, exactly. You know, it's like you build
20:55
Speaker 1: a golf course and then like a golf ball drops
20:58
Speaker 1: out of the sky and score the hole in one,
21:00
Speaker 1: and you're like, well, that's weird. Either golf balls fall
21:03
Speaker 1: out of the sky a lot more often than I thought,
21:06
Speaker 1: which makes this not so weird, or something really weird
21:09
Speaker 1: just happened, right, And that's the situation we're in. And
21:12
Speaker 1: so right there, it's odd, right, because it can tell
21:14
Speaker 1: you either that we were wrong, that maybe there are
21:17
Speaker 1: a lot more of these rocks than we thought, which
21:19
Speaker 1: is already sort of interesting after physically right to hear
21:22
Speaker 1: that space is full of interstellar rocks banging around, or
21:26
Speaker 1: you know, it was just a really really rare event,
21:29
Speaker 1: and you know, rare things happen, right, People do get
21:31
Speaker 1: holes in one act um sometimes when they don't expect.
21:35
Speaker 1: It's so rare things do happen. Or it's not just
21:38
Speaker 1: a rock, maybe it's something else, right, And that's why
21:41
Speaker 1: people dug in to understand, like what is this thing?
21:43
Speaker 1: What is it made out of? What else can we
21:45
Speaker 1: learn about it? Not only is it rare, but it
21:51
Speaker 1: was also going at a very rare speed, or like
21:54
Speaker 1: a very strange speed. Yeah, yeah, exactly. If you take
22:00
Speaker 1: the all the stars in our neighborhood, like our star
22:02
Speaker 1: and the nearby ones and the nearest few hundreds sort
22:05
Speaker 1: of in our galactic neighborhood, and you average all their
22:08
Speaker 1: speeds together, you get like, you know, imagine all those
22:11
Speaker 1: stars are like a sloshing ocean bouncing around. You know, Um,
22:14
Speaker 1: you gets sort of the average speed of that whole blob, right,
22:18
Speaker 1: And this thing was going at almost exactly that speed
22:21
Speaker 1: relative to us, right, which means you can sort of
22:25
Speaker 1: think of it like it wasn't moving. It was just
22:27
Speaker 1: sort of floating there in the galaxy and we moved
22:30
Speaker 1: through it. What what do you mean, Well, you can
22:32
Speaker 1: think if you think of like our galactic neighborhood is
22:35
Speaker 1: like an ocean, this is like a booey sort of
22:37
Speaker 1: floating in the ocean, right. And of course our sun
22:39
Speaker 1: is moving relative to the galaxy and our I mean
22:43
Speaker 1: everything is relative. Right. It passed through our solar system
22:46
Speaker 1: or we passed our solar system over it. Are the
22:49
Speaker 1: same statements, right, It's just how you think of the
22:51
Speaker 1: frame of reference, meaning like like we are the visitors
22:54
Speaker 1: to it. That's right. It was just having a nice
22:57
Speaker 1: picnic and we just sort of stormed down the loop.
23:00
Speaker 1: Are the freight train? Not it exactly. And it's it's
23:04
Speaker 1: a really odd kind of speed because it doesn't help
23:07
Speaker 1: us understand where it came from. Like, if it came
23:09
Speaker 1: from the neighboring star, we would expect it to roughly
23:12
Speaker 1: have that star's velocity with respect to the galaxy. Right, Um,
23:15
Speaker 1: if it came from another star, we you'd expected to
23:17
Speaker 1: have that star's velocity roughly, but it but no stars
23:21
Speaker 1: have this average velocity, right, most of them are moving
23:24
Speaker 1: relative to the galaxy. They're slashing around, So it's a
23:27
Speaker 1: pretty weird speed to have. It's an anomaly kind of
23:32
Speaker 1: like it's clear it didn't come from possibly the stars
23:36
Speaker 1: around us, And so the anomalies start to add up. Right,
23:39
Speaker 1: You're like, oh, well, maybe it's just a rock from
23:41
Speaker 1: another solar system. Um, okay, Well, actually turns out those
23:44
Speaker 1: are really rare. You're like, all right, well, rare things happen,
23:47
Speaker 1: but the rare things for this rock keep adding up.
23:49
Speaker 1: It's rare and weird in so many different, totally separate
23:53
Speaker 1: ways that it really makes you start to wonder. And
23:56
Speaker 1: I think the shape has allowed to do when capturing
23:59
Speaker 1: the public's imagination. Like, um, you know, if you had
24:02
Speaker 1: been like a like a ball or like a rock,
24:04
Speaker 1: like a you know, like a randomly shaped rock, then
24:07
Speaker 1: people would just say, oh, it's an asteroid. But the
24:10
Speaker 1: shape of it was also very very weird. Yeah, it's
24:13
Speaker 1: like ten times longer than it is wide right, it
24:16
Speaker 1: looks like a skyscraper. And they had all these drawings
24:20
Speaker 1: of like cigar shaped rocks or whatever, and let me
24:23
Speaker 1: just interject a little rant here about astronomy public relations.
24:28
Speaker 1: Every time we hear a story about astronomy, they always
24:31
Speaker 1: include an artist's conception what this thing might look like? Right,
24:36
Speaker 1: and it's and sometimes it's labeled very clearly artist conception
24:40
Speaker 1: basically made up, But often it's not. You know, it's
24:42
Speaker 1: just like they have this image that leads the article
24:44
Speaker 1: and people look at it like, oh, that's what it
24:46
Speaker 1: looks like, but we don't know what this thing looks like.
24:49
Speaker 1: Some artists sat down and imagined maybe it looks like this.
24:52
Speaker 1: Another artist would have made something totally different, and so
24:55
Speaker 1: it always frustrates me. I imagine, like in particle physics,
24:58
Speaker 1: can we have an artist and pression of what my
25:01
Speaker 1: data might look like? Come? Why do you guys do
25:03
Speaker 1: that all the time too? In particle physics? Don't you
25:05
Speaker 1: like the large hatdrink Clyder, Here is some big explosion
25:10
Speaker 1: with things coming out of the artist rendition those No, No,
25:14
Speaker 1: that's actual data, that's actual data. Sometimes we take liberties
25:19
Speaker 1: and we like, you know, higher clever cartoonists to make
25:21
Speaker 1: our stuff look more interesting, But we don't make up
25:24
Speaker 1: artists impression of data like that anyway. Um, Yes, this
25:30
Speaker 1: thing is like ten times longer than it is whine. Yeah,
25:32
Speaker 1: and that's kind of how a lot of times in
25:35
Speaker 1: movies a picture space ships right from alien civilizations, like
25:40
Speaker 1: long and skinny, kind of like the star the story
25:42
Speaker 1: in Star Wars. Would you buy that kind of space
25:44
Speaker 1: ship if you went shopping for one? It makes sense, right,
25:46
Speaker 1: I mean it's sort of like, Um, it's big, but
25:48
Speaker 1: you want it to be streamlined in a way. But
25:51
Speaker 1: why does it have to be streamlined? There's no atmosphere
25:53
Speaker 1: in space, right, Um, you can have any shape you want.
25:56
Speaker 1: It doesn't have to be space so dynamic. But was
25:59
Speaker 1: it going? Well? First of all, how did they know
26:01
Speaker 1: was that shape it was? If it was so far
26:03
Speaker 1: away and so small. Yeah, the reason they could tell
26:06
Speaker 1: is that it's um. The light from it was changing
26:09
Speaker 1: in a in a periodic way, and so they could
26:11
Speaker 1: tell had this shape not only because it was weirdly shape,
26:14
Speaker 1: but because it was tumbling. Right, So this thing is
26:16
Speaker 1: not moving in a smooth way like zooming along um
26:20
Speaker 1: in the direction of its length. You imagine a spaceship
26:23
Speaker 1: is long and thin, it's zooming sort of in the
26:25
Speaker 1: direction from its back to its front. Right, This thing
26:29
Speaker 1: is not. It's tumbling, right, it's long and thin, but
26:32
Speaker 1: it's tumbling like a you know, a tennis racket head
26:35
Speaker 1: over heels, right, it's um it's it's tumbling around a
26:39
Speaker 1: short axis. So that's not the kind of spaceship you
26:41
Speaker 1: want to ride in. There's like a fun spaceship for
26:43
Speaker 1: the hidians, you know, about five seconds and until you
26:48
Speaker 1: start vomiting in space, which I don't think it's very fun.
26:51
Speaker 1: Well you don't need you never know what A and
26:53
Speaker 1: he's are into. You know. Maybe that's now you're right.
26:56
Speaker 1: I'm always saying we should broaden our minds and so
26:59
Speaker 1: what aliens might be like, and so yeah, maybe aliens
27:01
Speaker 1: enjoy vomiting. I think you might be right there. So
27:04
Speaker 1: the way you could tell a shape by the way
27:07
Speaker 1: the light, even though it looks like a pinpoint, the
27:09
Speaker 1: way that light from that pinpoint was changing sort of
27:12
Speaker 1: told you that it was there was something in it
27:15
Speaker 1: spinning and it was roughly the shape. Yeah, And if
27:18
Speaker 1: something was spherical and it was spinning, then it wouldn't
27:20
Speaker 1: be changing its apparent shape to us, right, But if
27:23
Speaker 1: it's spinning or tumbling it has a long shape, then
27:26
Speaker 1: the part that reflects light keeps changing, right, and so
27:29
Speaker 1: you see more or less and more or less. And
27:31
Speaker 1: that's how they made these estimates. A lot of really
27:33
Speaker 1: good science went into extracting all this information out of
27:37
Speaker 1: a very small amount of data. Wow, it seems almost fantastical,
27:41
Speaker 1: like an artist rendition. But you're saying, like if it
27:44
Speaker 1: was a death star or circular, it would not the
27:47
Speaker 1: life from it wouldn't be it wouldn't vary. Yeah, exactly,
27:51
Speaker 1: it wouldn't vary. And so it's tumbling, which is odd also,
27:55
Speaker 1: but also the fact that it's so long and thin
27:57
Speaker 1: as unusual. I mean, we look around at the population
27:59
Speaker 1: of rocks in our solar system. You don't see rocks
28:02
Speaker 1: like that, Like, you know, rocks are mostly spherical because
28:06
Speaker 1: of gravity and collisions and stuff like that. Sometimes they
28:09
Speaker 1: get longer and thinner. But like maybe three to one
28:12
Speaker 1: or five to one, ten to one for a link
28:15
Speaker 1: to with ratio is really weird, okay, And there's other
28:18
Speaker 1: weird things about it, not just the shape, not just
28:21
Speaker 1: to be, not just the direction it was going. There's
28:24
Speaker 1: like these mysteries just keep compounding, Like we haven't even
28:27
Speaker 1: talked about the craziest one. It gets crazier, all right,
28:31
Speaker 1: gets so much crazier. Yeah, let's talk about that a
28:34
Speaker 1: little bit more. But first quick break, what's the next one?
28:50
Speaker 1: It's a very shiny apparently, Yeah, it's really really shiny.
28:54
Speaker 1: We're like, what is it? You know, we don't know
28:56
Speaker 1: what this thing is made out of? Um, but based
28:58
Speaker 1: on its size and it's it's cetera, we know that
29:00
Speaker 1: it's like ten times shinier than anything in any of
29:04
Speaker 1: our asteroids, you know, like, what is this thing? It's
29:07
Speaker 1: so bright, it reflects lights so much. We don't know
29:10
Speaker 1: what it's made out of. It. That's the only clue
29:11
Speaker 1: we have is that it's super shiny. Our asteroids are
29:14
Speaker 1: sort of mostly like dark gray, right, Like, yeah, I
29:16
Speaker 1: think they're they're gray or red based on how much
29:19
Speaker 1: iron or whatever they have in them. But this was
29:21
Speaker 1: a ten times shinier. So it's like a giant, gleaming, gleaming, silver, sparkling,
29:28
Speaker 1: shiny unicorn horn flying through space. I know it makes
29:32
Speaker 1: you wonder, like it gives you the image of a
29:34
Speaker 1: sparkling spaceship, right, um, so you gotta wonder, um and
29:39
Speaker 1: the thing that makes you think, wow, maybe this thing
29:41
Speaker 1: could be a spaceship is that as it passed through
29:44
Speaker 1: our solar system. So here's the weirdest thing. As it
29:46
Speaker 1: passed through our solar system, we can track its motion
29:49
Speaker 1: and we can predict its motion based on gravity. Right,
29:52
Speaker 1: if something is just falling through gravity, we can tell
29:54
Speaker 1: how it's going to go. But it didn't follow that path.
29:57
Speaker 1: It looks like as it went through our solar system
30:00
Speaker 1: it accelerated. What Yeah, they hit the gas. It hit
30:05
Speaker 1: the gas. Yeah, it came into our solar system and
30:08
Speaker 1: on its way out it floored it. It's like the
30:10
Speaker 1: freight train was going through your town and then and
30:13
Speaker 1: then it was thinking. The conductor was thinking, oh no,
30:15
Speaker 1: I'm not gonna stop here for sure, this crap hole.
30:20
Speaker 1: I'm just just gonna I'm just gonna, you know, step
30:23
Speaker 1: on the accelerator. Yeah, it's like, let's get out of
30:26
Speaker 1: town quick. Let's not exaggerate. It's already super weird. It
30:29
Speaker 1: definitely accelerated. It didn't like double its speed. It's a
30:32
Speaker 1: small effect, but it's definitely there. Definitely happened. Like we
30:35
Speaker 1: can measure it precisely enough to say that there was
30:38
Speaker 1: some acceleration and it wasn't just due to the sun
30:41
Speaker 1: or it wasn't like the Sun was pulling on it
30:43
Speaker 1: or anything. Well, the Sun was pulling on it, right,
30:45
Speaker 1: that's the gravitational force, but it moved in a way
30:48
Speaker 1: that required something else to explain it. It It requires the
30:50
Speaker 1: Sun's gravity plus an extra push. And that's the question.
30:54
Speaker 1: Where did that push come from? What what force did
30:58
Speaker 1: it use to accelerate? Yeah, exactly. And so before you
31:02
Speaker 1: go to like, well, there must have been an engine
31:04
Speaker 1: on it and it was, you know, hitting the gas
31:06
Speaker 1: on the way out, there are some other possible explanations
31:09
Speaker 1: like maybe it has ice on it, and when it
31:12
Speaker 1: came through the Solar system, that ice was melted, and
31:15
Speaker 1: that ice like it shoots out and forms a gas
31:18
Speaker 1: and basically forms like a tail like a comet, and
31:20
Speaker 1: that can give it a push like a rocket like
31:22
Speaker 1: it was. Yeah, but a natural rocket, not like you know,
31:26
Speaker 1: an engine fabricated in another solar system. It could just
31:30
Speaker 1: be like a block of ice on one side that's
31:31
Speaker 1: got turned into gas and that's how a rocket would
31:33
Speaker 1: work out. But they didn't see this gas, right, Yeah,
31:36
Speaker 1: they looked at it really carefully, and the thing has
31:38
Speaker 1: no gas around it, there's no tail, so there's no
31:41
Speaker 1: evidence of any ice turning into gas or anything like that,
31:44
Speaker 1: so we still don't understand it. Wow. Okay, So in
31:48
Speaker 1: case people missed it, this thing flew by our into
31:51
Speaker 1: our solar system and very close to the Earth. Yeah,
31:54
Speaker 1: exactly end of this weirdly shaved you know two asked
32:00
Speaker 1: accelerating shiny, strangely shaped object that we should never have seen.
32:06
Speaker 1: That is almost impossible for it to exist. Um, just
32:12
Speaker 1: went by our planet. It came by, it checked us out,
32:14
Speaker 1: and it hit the gas on the way out. And
32:18
Speaker 1: and you know, you might wonder, like, what are the
32:19
Speaker 1: other explanations for it accelerating? Yeah, like what's what's the
32:24
Speaker 1: most likely explanation? We don't have a most likely explanation.
32:27
Speaker 1: Another plausible one is maybe it's really big and flat. Right.
32:32
Speaker 1: If it's big and flat, then it can act like
32:34
Speaker 1: a sail. It can catch sort of the Sun's radiation
32:38
Speaker 1: and act like a sail in space. It's called a
32:40
Speaker 1: solar sail. It basically catches the solar wind. So one
32:44
Speaker 1: explanation for the speed, right, but none the acceleration. It
32:48
Speaker 1: doesn't explain all those other things. It doesn't explain all
32:51
Speaker 1: those other things. But it could explain the acceleration. On
32:54
Speaker 1: the other hand, if you're thinking, well, big and flat,
32:56
Speaker 1: that's pretty weird for a rock, right, Yeah, it is
32:59
Speaker 1: pretty weird for a rock. Nature doesn't make big flat
33:02
Speaker 1: sheets of material very often, right, You don't see those
33:05
Speaker 1: in our solar system. What makes that, well, civilizations, Right,
33:09
Speaker 1: So it's fantastic to think about. Maybe this is a
33:12
Speaker 1: piece of alien junk. Right, Maybe this is like space archaeology.
33:17
Speaker 1: Some ship blew up in a war somewhere a billion
33:19
Speaker 1: years ago, and this is just like a hunk of
33:21
Speaker 1: it flying through space with some sort of rocket attached
33:25
Speaker 1: to it. No, it could just be a big flat
33:28
Speaker 1: sheet of metal and it gets a little boost from
33:30
Speaker 1: the solar wind as it passes through, and that's why
33:33
Speaker 1: it's not just moving gravitationally. The acceleration could be explained
33:37
Speaker 1: it just if it had that shape. On the other hand,
33:39
Speaker 1: it could have been a purposely designed solar sale, right,
33:43
Speaker 1: that's a way to get around the galaxy. Build these
33:45
Speaker 1: sales and go from star to star and get a
33:47
Speaker 1: little push as you go by each one. Or you
33:49
Speaker 1: made me think of it was like a Shinese silver surfboard,
33:53
Speaker 1: like silver surfer Yeah, exactly, It's fascinating to think of
34:05
Speaker 1: all the ways that this thing is weird, and all
34:07
Speaker 1: the possible explanations that we we sort of hope for,
34:10
Speaker 1: right the ones we want, the stories we'd like to tell.
34:13
Speaker 1: And the thing I love about this object is that
34:15
Speaker 1: it resists conventional explanation. You try to come up with
34:18
Speaker 1: some explanation you think makes sense. No, well, how do
34:21
Speaker 1: you explain this? And how do you explain that it's
34:23
Speaker 1: got so many different ways of being weird? Which could
34:26
Speaker 1: mean either it's just kind of like a miracle, like
34:29
Speaker 1: this crazy unlikely event that happened, or maybe our view
34:33
Speaker 1: of the universe is totally wrong, and maybe maybe um,
34:38
Speaker 1: we got it all wrong and it's not that rare
34:40
Speaker 1: for this to happen exactly. So either it's a rare
34:43
Speaker 1: event and you know, we're just sort of lucky afternomically
34:45
Speaker 1: to get to see it, or as you say, it's
34:48
Speaker 1: less rare than we expect and maybe we'll see more
34:50
Speaker 1: of them, right, that would be pretty cool. Um, Or
34:54
Speaker 1: it's not a natural phenomenon, right, maybe it is aliens. Right,
34:57
Speaker 1: we can't rule that out, but in any case, it's
35:00
Speaker 1: gone right, it's it went by already it's gone if
35:04
Speaker 1: you wanted to know more about it too late, Yes,
35:07
Speaker 1: it's gone, but it's not too late to learn more
35:09
Speaker 1: about it. I mean we could potentially build like a
35:12
Speaker 1: fast rocket that takes a slingshot around Jupiter and zooms
35:15
Speaker 1: out there or something a long time to catch up. Yeah,
35:18
Speaker 1: it would take a long time to catch up to it,
35:21
Speaker 1: and by the time it did, it would be like
35:23
Speaker 1: twenty years before it got there and sent us pictures
35:25
Speaker 1: back and stuff. Who knows if we even have a
35:27
Speaker 1: society in twenty years, right, I send data back to
35:30
Speaker 1: the smoking rubble of Western civilization. That's a that's a
35:33
Speaker 1: cheery thought, right. The better opportunity is just to build
35:36
Speaker 1: a bigger telescope, oh to see it. But isn't it
35:39
Speaker 1: too late? Isn't already sort of? I mean it's leaving
35:42
Speaker 1: a twenty six kilometers per second? Yeah, But fortunately we've
35:46
Speaker 1: been building a really awesome new telescope for the last
35:49
Speaker 1: I don't know, en years, and it's going to turn
35:51
Speaker 1: on in a few years. It's called the Large Synoptics
35:54
Speaker 1: Survey Telescope, and it's going to be pretty awesome, and
35:56
Speaker 1: it's going to turn on in about three years and
35:58
Speaker 1: when it does, it's going to give us pictures like
36:00
Speaker 1: nothing's ever seen before. And um, and it might be
36:04
Speaker 1: able to give us good pictures of this crazy thing.
36:08
Speaker 1: But wouldn't it have been better to look at it
36:09
Speaker 1: when it was going through the Solar system? You know,
36:12
Speaker 1: I get a good look that. Um. Yes, it would
36:16
Speaker 1: have been um. But we didn't know it was coming,
36:18
Speaker 1: so we weren't prepared. We were lucky we even saw it.
36:21
Speaker 1: It was a short notice, yeah, exactly. Um, you know
36:25
Speaker 1: we saw it when it was already like deep into
36:28
Speaker 1: our solar system. It's not the kind of thing we
36:29
Speaker 1: were looking for, right. Nobody sets out to find these
36:31
Speaker 1: things because you expect them to never come. Well, that
36:34
Speaker 1: just kind of tells you that on a daily basis,
36:36
Speaker 1: like we are still seeing things about the universe that
36:40
Speaker 1: are completely inexplicable, exactly. And that's what I love about
36:44
Speaker 1: astronomy and space physics that almost every time we look
36:47
Speaker 1: out there in the cosmos, we see something crazy. Right,
36:51
Speaker 1: It's full of surprises. There's so many things out there
36:54
Speaker 1: which if we could see them or learn them, or
36:56
Speaker 1: if they visited us, would blow our minds with the
36:59
Speaker 1: way they change perspective about our lives and the universe
37:02
Speaker 1: and how everything works. Well, if you're an alien writing
37:05
Speaker 1: on and you're listening to this podcast, we just want
37:09
Speaker 1: to say hello, Thanks for visiting. Why didn't you stop
37:14
Speaker 1: and say hi? Was it our breath? Thanks for not
37:18
Speaker 1: sucking our brains out of our newses see you later,
37:23
Speaker 1: Thanks for listening everyone, see you next time. If you
37:34
Speaker 1: still have a question after listening to all these explanations,
37:37
Speaker 1: please drop us a line. We'd love to hear from you.
