- 0:01Speaker 1: Welcome to Stuff you Should Know from House Stuff Works
- 0:04Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh Clark,
- 0:13Speaker 1: There's Charles W Chuck Bryant, and there's Jerry So it's
- 0:16Speaker 1: Stuff you Should Know. Wow. Uh, first of all, I
- 0:21Speaker 1: think we should go ahead and apologize to eight Stuff
- 0:28Speaker 1: you Should Know fans. And there were more than who
- 0:30Speaker 1: have already heard this. Yeah, we went to the World
- 0:34Speaker 1: Science Festival. We were invited to the World Science Festival
- 0:36Speaker 1: in New York City, and we want to give a
- 0:39Speaker 1: little special shout out to Ben in the Ace Hotel
- 0:41Speaker 1: for putting us up while we were there. Yeah. We
- 0:43Speaker 1: did a live podcast short form on Washington Square Park
- 0:48Speaker 1: on a Sunday afternoon. It was kind of a neat thing.
- 0:51Speaker 1: So um, yeah, I hate everybody who came out to
- 0:53Speaker 1: see us. We appreciated the support. Yeah, actually I thought
- 0:56Speaker 1: I knew everyone by name. There were actual Stuff you
- 0:58Speaker 1: Should Know fans. Yeah, I was gonna apologize to them directly.
- 1:02Speaker 1: There were some people who clearly were not familiar with us,
- 1:05Speaker 1: and we're just mind blown walking around glazed look in
- 1:09Speaker 1: their face. They look kind of defeated. I was like, oh,
- 1:14Speaker 1: you like Stuff you Should Know? Now. Yeah. I had
- 1:16Speaker 1: a couple of people come up and be like, hey,
- 1:17Speaker 1: what do you guys do? This is neat and said, well,
- 1:19Speaker 1: you just saw a short version of it. My friend,
- 1:21Speaker 1: if you want a lot more side stories and anecdotes,
- 1:26Speaker 1: then tune into the long version. Yeah, we had twenty minutes.
- 1:29Speaker 1: We had twenty minutes that boy, we had to get
- 1:31Speaker 1: down to business. Didn't and we did too. It's not bad.
- 1:34Speaker 1: We didn't talk about tire stores or anything like that.
- 1:36Speaker 1: We just talked about the Wow signal. Yeah, this is um.
- 1:41Speaker 1: I think this is fascinating stuff because this is something
- 1:45Speaker 1: that even the most hardened skeptic hasn't been able to
- 1:48Speaker 1: fully debunk. Yeah, that's that's a good point. It's pretty
- 1:51Speaker 1: neat that you know they're they're upset, probably, so we
- 1:55Speaker 1: should say that. We keep saying the wild signal, and
- 1:58Speaker 1: Chuck's talking about skeptics and everything. There is evidence of
- 2:04Speaker 1: a potential transmission from an alien civilization here on Earth,
- 2:11Speaker 1: and it's been here on Earth, printed out sitting in
- 2:14Speaker 1: the Ohio State University Archives since the nineteen seventies. Yeah,
- 2:19Speaker 1: and potential is the key word there. I think that's
- 2:21Speaker 1: where most skeptics head will pop off. But you got
- 2:24Speaker 1: you gotta say potential you and I did. Yeah, I
- 2:27Speaker 1: don't want anybody's head to pop off, you know. Um,
- 2:30Speaker 1: the thing is, like you said, Chuck, no skeptic has
- 2:34Speaker 1: been able to say, here's your explanation, dumb, dumb, And
- 2:38Speaker 1: they've tried. There have been plenty of explanations, but every
- 2:41Speaker 1: single one has been systematically addressed and reduced the rubble basically. Um,
- 2:48Speaker 1: so the whole thing finds its roots. Um, like I
- 2:52Speaker 1: said back in the seventies, but actually goes further back
- 2:54Speaker 1: than that. There's a lot of Um. There's been a
- 2:59Speaker 1: lot of talk starting in the twentieth century over aliens.
- 3:03Speaker 1: Are we the other other people? Are we the only
- 3:05Speaker 1: life out there? Um? Are there other people on other planets?
- 3:10Speaker 1: And if so, can we communicate with them? And astronomers
- 3:15Speaker 1: started crunching the numbers and doing the math and said,
- 3:19Speaker 1: we basically have two things we can do here. We
- 3:22Speaker 1: can try to go visit aliens and look for them
- 3:25Speaker 1: in the flesh, expensive, expensive, and potentially impossible. It's like
- 3:32Speaker 1: looking for a needle in a haystack. Yeah, but also
- 3:34Speaker 1: it's the closest, um, the closest planet to us is
- 3:37Speaker 1: like a few hundred light years away. I believe four
- 3:42Speaker 1: hundred plus, right, which means that, um, we take four
- 3:48Speaker 1: hundreds something years traveling at the speed of light to
- 3:50Speaker 1: reach that planet. So we couldn't go find them. Instead,
- 3:55Speaker 1: we decided that we would try to listen out to
- 3:58Speaker 1: see if anybody was really leasing any transmissions out there
- 4:01Speaker 1: and find traces of alien civilizations that way. Yeah, and um,
- 4:06Speaker 1: did we do a show on set. No, we've talked
- 4:10Speaker 1: about it before, all right, the Search for Extra Oh yes,
- 4:13Speaker 1: did we? We did. I don't remember when it came in.
- 4:18Speaker 1: We definitely have talked about it before. Now that you
- 4:21Speaker 1: say that, I think with one of our south By
- 4:25Speaker 1: Southwest or comic cons might have had something to do
- 4:27Speaker 1: with Oh yeah, the UFOs SSETTI, the Search for Extraterrestrial Intelligence.
- 4:34Speaker 1: It's not a single organization, although there is the SETI
- 4:37Speaker 1: Institute now since the early nineteen eighties. But SET is
- 4:41Speaker 1: a bunch of different groups that um are. They're not
- 4:46Speaker 1: tinfoil hat wearing crack pots who are bounded determined to
- 4:50Speaker 1: find if there's life out there, but they're open minded
- 4:53Speaker 1: folks that say, if there isn't life out there, let's
- 4:57Speaker 1: get ahead of the game here and listen out for
- 4:59Speaker 1: him and see if they're trying to say something to
- 5:01Speaker 1: us right there. They're basically people who say the there's
- 5:04Speaker 1: just too many stars out there that have planets and
- 5:09Speaker 1: that have are potentially habitable to life for us. It
- 5:14Speaker 1: just it just it boggles their mind to think that
- 5:17Speaker 1: we are the only living beings. And they're scientists, right,
- 5:21Speaker 1: And to these scientists the much more logical conclusions that
- 5:24Speaker 1: were one of many um civilizations out there, and so
- 5:28Speaker 1: they have dedicated their their astronomical talents to searching for that. Yeah,
- 5:35Speaker 1: and this all started happening in the early nineteen seventies
- 5:37Speaker 1: and Earnest and uh, I think it actually started in
- 5:40Speaker 1: the sixties and Earnest. But with the Big Ear it
- 5:44Speaker 1: was in the seventies, their steady program, that's right, nineteen
- 5:49Speaker 1: seventy three, the Ohio State University Radio Observatory. I love
- 5:54Speaker 1: that laugh every time. Um, they have something called the
- 5:57Speaker 1: Big Ear, or had something called the Big Ear. Yeah,
- 6:00Speaker 1: they needed a golf course, though, yes they did, so
- 6:02Speaker 1: they got rid of the Big Year. Even worse than that, Um,
- 6:05Speaker 1: the Big Ear Radio Telescope Ohio State was demolished, not
- 6:10Speaker 1: to build the golf course. But to expand an existing
- 6:13Speaker 1: golf course, we need another nine holes, right, we need
- 6:16Speaker 1: another clubhouse. Well, I think the Big Year had seen
- 6:20Speaker 1: its best days by that point, So don't feel bad
- 6:22Speaker 1: for the Big Year. I still feel bad for the
- 6:23Speaker 1: Big Year. So nineteen seventy three, the Big Ears starts
- 6:27Speaker 1: scanning listening for stuff out in outer space, hence the name,
- 6:32Speaker 1: and UM what would happen is because it was seventy three, Uh,
- 6:37Speaker 1: it would print stuff out on a dot matrix printer
- 6:41Speaker 1: and UH student would uh student assistant would take that
- 6:45Speaker 1: print out of of what it was listening to and
- 6:48Speaker 1: take it to another volunteer, UM teachers, professors, and they
- 6:53Speaker 1: would just basically look at all these numbers. Yeah, page
- 6:57Speaker 1: by page by page. If you've ever seen the wild signal,
- 7:00Speaker 1: you it's just numbers ones, twos, maybe a three here there. Yeah,
- 7:04Speaker 1: it's the level of background noise in space exactly. So, um,
- 7:08Speaker 1: A one is blip a radio transmission that was one
- 7:12Speaker 1: time the intensity of the normal background noise in space
- 7:16Speaker 1: on a particular frequency. Right, A one is nothing like
- 7:20Speaker 1: there's ones all over the place all the time. There's ones,
- 7:23Speaker 1: twos and threes. Yeah, very common stuff. Um. And so
- 7:27Speaker 1: this these these poor astronomers who were donating their time
- 7:31Speaker 1: to the bigger telescope. We're basically they were the the
- 7:37Speaker 1: They were analyzing the stuff with their eyes. Yeah, there
- 7:42Speaker 1: wasn't like a computer program they spit it into. They
- 7:45Speaker 1: looked at this computer print out sheet after sheet after sheet, right,
- 7:48Speaker 1: So for they would look at a whole night's scan
- 7:53Speaker 1: of deep space from a radio telescope, again with their
- 7:57Speaker 1: eyes going over sheets and heets of computer paper, dot matrix,
- 8:02Speaker 1: printer paper, and UM, that's what this guy named Jerry Aman,
- 8:05Speaker 1: who was an astronomer at Ohio State, was doing UM
- 8:09Speaker 1: on August eighteen, nineteen seventy seven. He was looking over
- 8:13Speaker 1: some stuff from three days before. Yeah, and so he's
- 8:18Speaker 1: scanning all the stuff and there's ones, twos, and threes,
- 8:21Speaker 1: and he's you know, he's watching uh, Love American Style
- 8:24Speaker 1: on TV and eating his TV dinner and he's bored
- 8:27Speaker 1: out of his mind love American stuff and he's bored
- 8:31Speaker 1: out of his skull. And then UM, well here's another
- 8:34Speaker 1: important thing to point out, because it was also nineteen
- 8:37Speaker 1: seventy three, that was the seventy seven. At this point,
- 8:41Speaker 1: they didn't have UM double digit print outs. It just
- 8:46Speaker 1: went one through nine and then started with the letter A, B, C,
- 8:50Speaker 1: D AS ten, eleven, twelve and so on, right exactly.
- 8:53Speaker 1: So he's reading this stuff and he sees six e
- 8:58Speaker 1: q U J five, which means the transmission at its
- 9:03Speaker 1: peak of you peaked at thirty times louder than anything
- 9:06Speaker 1: they had ever seen before. Then the normal background noise,
- 9:10Speaker 1: and he circled it and put wow exclamation point on
- 9:13Speaker 1: the paper. And that's why it's the Wow signal, exactly.
- 9:16Speaker 1: And this is a big deal. I mean, like, in
- 9:18Speaker 1: this whole huge ream of dot matrix paper filled with
- 9:22Speaker 1: ones and twos and maybe a three here there, there's
- 9:25Speaker 1: a you standing in the middle of this string which
- 9:30Speaker 1: was high. Yeah. I mean six alone would be like whoa,
- 9:33Speaker 1: this is kind of significant. This thing went up to you,
- 9:36Speaker 1: and like you said, he circled it and wrote wow
- 9:38Speaker 1: next to him. It became the Wow signal, and um,
- 9:42Speaker 1: almost immediately they started investigating this thing. Sure, And there
- 9:46Speaker 1: are a lot of details to the Wow signal that
- 9:50Speaker 1: are make it even more impressive than just the fact
- 9:53Speaker 1: that it peaked at you, started at six and ended
- 9:55Speaker 1: at five and peaked at you. There's a lot of
- 9:58Speaker 1: different aspects of the Wow signal that make people say,
- 10:01Speaker 1: what in the name of God is this? And we
- 10:06Speaker 1: will start getting those details right after this break. So, Chuck,
- 10:25Speaker 1: we were talking about how the wild signal looks on
- 10:29Speaker 1: dot matrix papers six e q u J five, and
- 10:33Speaker 1: that means that at its peak it goes from six
- 10:35Speaker 1: times the normal background noise all the way up to
- 10:38Speaker 1: thirty times and then back down to five times the
- 10:41Speaker 1: normal background noise over what we know over seventy two seconds, Yes,
- 10:47Speaker 1: which is very significant. It turns out so um. The
- 10:52Speaker 1: Big Ear telescope, we should say a little bit more
- 10:54Speaker 1: about it was a crowds telescope. It was built in
- 10:56Speaker 1: the sixties and it didn't move it um eavesdropped on
- 11:02Speaker 1: the electromagnetic radio spectrum UM coming from outer space. Eaves
- 11:09Speaker 1: dropped on it. But it used the rotation of the
- 11:12Speaker 1: Earth to move it. Yeah, it didn't pan its little
- 11:16Speaker 1: big ear back and forth. It wasn't a show off, No,
- 11:19Speaker 1: it just stayed fixed. The rotation the Earth very slowly
- 11:22Speaker 1: would pick up a new patch of Earth at the
- 11:26Speaker 1: rate of the Earth spin right. So um, the big
- 11:28Speaker 1: ears the sky at the rate of the Earth spin right,
- 11:30Speaker 1: and so it's just pointing out there in deep space,
- 11:33Speaker 1: and as the Earth rotates, it would move the big
- 11:36Speaker 1: ears field of reception I guess across any given point
- 11:41Speaker 1: in the sky over a seventy two second period. And
- 11:46Speaker 1: it just so happens that the six e q u
- 11:50Speaker 1: J five wild signal transmission was seventy two seconds, which
- 11:55Speaker 1: suggests something very important here, Chuck. It suggests that the
- 11:59Speaker 1: wild signal came from a fixed point in the sky
- 12:02Speaker 1: that was staying in one place, and the Big Year
- 12:06Speaker 1: just swept past it over the course of its normal
- 12:08Speaker 1: seventy two seconds. Yeah, And uh, I liken it to
- 12:11Speaker 1: like if you're driving through the desert listening to your radio. Uh,
- 12:16Speaker 1: your signal, the further you are from that radio transmitter
- 12:20Speaker 1: or that radio station is going to be pretty faint.
- 12:23Speaker 1: And then as you get closer and have that direct signal,
- 12:25Speaker 1: it's gonna peak. And then as you drive further past it,
- 12:28Speaker 1: it's gonna get more faint again. And that's what shape
- 12:31Speaker 1: that this wild signal took. It took the shape of
- 12:33Speaker 1: a pyramid if you graph it out. And I believe
- 12:36Speaker 1: that's the Doppler effect because I always hear the Doppler
- 12:38Speaker 1: effect being explained by how an ambulance siren sounds far
- 12:42Speaker 1: away and then gets louder as it gets closer, and
- 12:45Speaker 1: then it gets, you know, weaker, the further way you get. Yeah, well,
- 12:49Speaker 1: it also changed his pitch though, isn't that the Doppler effect?
- 12:52Speaker 1: I think so. It's not just loudness. It's like er
- 12:56Speaker 1: er er. If you're in England, did you change pitch
- 13:01Speaker 1: just then? Yeah, you didn't hear any difference. No, you
- 13:05Speaker 1: didn't hear it go down in volume. You didn't hear
- 13:08Speaker 1: it go down in in tone? No? Wow? Did you really?
- 13:12Speaker 1: Are you tone deaf? I don't think so. It would
- 13:15Speaker 1: explain a lot as far as karaoke goes. Do you
- 13:20Speaker 1: sind karaoke? Did you recently? What do you say? Um?
- 13:26Speaker 1: I got some songs here there? You can't You can't
- 13:28Speaker 1: tell us one of them? Is that too revealing? No?
- 13:32Speaker 1: Let me think of one of my karaoke songs. My
- 13:36Speaker 1: big move is always under pressure and someone's always like, oh,
- 13:39Speaker 1: i'll do it with you'll do the bowie part. I
- 13:41Speaker 1: might not do both parts. I recently sang um I
- 13:44Speaker 1: have a tiger. Oh, yeah, there you go. I have
- 13:46Speaker 1: a big problem though, with my karaoke stuff. A lot
- 13:49Speaker 1: of the songs that I pick are just slightly out
- 13:52Speaker 1: of the key that I can comfortably achieve. Well, if
- 13:55Speaker 1: you're picking eighties rock, then yeah, but you would think
- 13:59Speaker 1: the Tiger that the the guy's not singing that high picture,
- 14:01Speaker 1: although I know he hits that high note and I
- 14:03Speaker 1: knew that, But from the start that guy starts out
- 14:06Speaker 1: like a little higher than I can go. So it's
- 14:09Speaker 1: just it's not necessarily a treat for everyone around me
- 14:13Speaker 1: when I'm singing karaoke, because I accidentally every once in
- 14:17Speaker 1: a while I have a night where like every song
- 14:18Speaker 1: I pick is right in my wheelhouse and I'm nailing him.
- 14:21Speaker 1: But for the most part, it's uh yeah, I woarrible
- 14:26Speaker 1: a little bit. I guess I think the key to
- 14:28Speaker 1: karaoke is to get your songs that you know you
- 14:30Speaker 1: can do and kind of stick to those. Well, I'm
- 14:32Speaker 1: I'm not like a pro. Well you know, uh like
- 14:36Speaker 1: I did Foreigners Cold as Ice one time by accident
- 14:39Speaker 1: because the song I wanted to do, I think, under pressure,
- 14:42Speaker 1: someone had done and I was they were calling me.
- 14:44Speaker 1: I was like, oh, well, I guess I'll just do this,
- 14:46Speaker 1: and the karaoke guy hit in Philadelphia said, well, I
- 14:48Speaker 1: hope you're hope you can have a vice for your testicles,
- 14:52Speaker 1: but you didn't say testicles why? And then I remembered
- 14:56Speaker 1: how high that song was. It is. It's a disaster
- 15:00Speaker 1: that I have the Tigers not that far off. Um
- 15:04Speaker 1: and I should give a plug here to um. Sig
- 15:08Speaker 1: Gold's Request Room. If you're in New York City, you
- 15:12Speaker 1: should go to sig Gold's Request Room. It's on one
- 15:16Speaker 1: of those private karaoke twenty six. It's not private. It's
- 15:19Speaker 1: just a piano karaoke bar, not private room. But it's
- 15:24Speaker 1: a back room with like a heavy curtain, so there's
- 15:27Speaker 1: a sense that it's private, but it's not private. It's
- 15:30Speaker 1: just you just show up and but it's live. It's
- 15:32Speaker 1: a guy playing piano instead of a backing track. Yeah,
- 15:34Speaker 1: it's a guy named Joe McGuinty. He's a very good
- 15:37Speaker 1: talented musician. He's actually a friend of you, Mace, and
- 15:41Speaker 1: he used to play for the Psychedelic First and he
- 15:44Speaker 1: now he's one of the owners of Sig Gold's Request Room. Man,
- 15:48Speaker 1: that place is gonna blow up now, I hope so
- 15:50Speaker 1: it should. It's a lot of fun. Yeah, Alright, boy,
- 15:53Speaker 1: that was a good segue or not segue, because that
- 15:56Speaker 1: leads to nothing. No, it leads to how do we
- 16:00Speaker 1: get on that Doppler effect? Yeah? Exactly, So, uh, let's
- 16:05Speaker 1: talk about set again. Let's bring this all back home
- 16:09Speaker 1: set or the different STIs around the world. Decided at
- 16:12Speaker 1: one point that UM, like you said, a good way
- 16:15Speaker 1: to find transmission might be to listen out for it.
- 16:19Speaker 1: And if we're gonna listen, UM, what would be the
- 16:23Speaker 1: most likely UM radio station that they would transmit? Well, yeah,
- 16:28Speaker 1: I mean like and of course it's not a radio station.
- 16:30Speaker 1: I'd say that as a joke, but but that was
- 16:33Speaker 1: the first That was the first. Um. That wasn't the
- 16:37Speaker 1: first thing they thought of. Like if if you say, okay,
- 16:41Speaker 1: we can't go to distant planets to start searching for aliens,
- 16:45Speaker 1: there's just it's just too far away. We would all
- 16:48Speaker 1: die on the way there. Right, we're gonna wait for
- 16:51Speaker 1: them to come down and play a mood at Devil's Tower. Instead,
- 16:57Speaker 1: we're gonna look for traces of them. Yeah, how can
- 17:00Speaker 1: we find But that were listening wasn't immediately the thing.
- 17:04Speaker 1: They started thinking like in different ways that you could
- 17:07Speaker 1: find evidence of alien civilizations. And finally what they settled
- 17:12Speaker 1: on was there, if you're an alien civilization, you are
- 17:16Speaker 1: probably familiar with the electromagnetic spectrum, So let's start looking there.
- 17:21Speaker 1: And they started looking at the electromagnetic spectrum to see
- 17:25Speaker 1: maybe where you would find some sort of evidence of
- 17:28Speaker 1: alien civilization. And they thought, how about the radio band. Yeah,
- 17:31Speaker 1: there were a couple of physicists from Cornell in the sixties,
- 17:35Speaker 1: Philip Morrison and Giesipicconi, who reckoned that, you know, they're
- 17:40Speaker 1: going to find a common language. They're going to broadcast
- 17:43Speaker 1: on what's like the most common language of the universe,
- 17:50Speaker 1: hydrogen Espanola, espaniola. Not quite uh. I'm sort of being
- 17:58Speaker 1: fun here with like saying, it's a radio stay and
- 18:00Speaker 1: it's a line. But hydrogen is the most abundant common
- 18:03Speaker 1: element in the universe, and there is a hydrogen line
- 18:06Speaker 1: hydrogen frequency, so they figured this may be a good
- 18:10Speaker 1: place to start listening. Yeah, and and um, Hydrogen's protons flip.
- 18:14Speaker 1: They change spin pretty pretty much all the time, right,
- 18:20Speaker 1: And as they flip and change their spin, they admit
- 18:24Speaker 1: a little bit, just a tiny teensy bit of electromagnetic radiation,
- 18:27Speaker 1: like a little glow right, and that the frequency of
- 18:31Speaker 1: that emission is at four hundred and twenty mega hurts.
- 18:36Speaker 1: Since hydrogen is the most abundant element in the universe
- 18:40Speaker 1: and hydrogen is flipping all of the time, it's also
- 18:44Speaker 1: emitting this radiation all the time, which makes twenty mega
- 18:48Speaker 1: hurts the most common frequency on the entire electro magnetic spectrum.
- 18:55Speaker 1: Oh hydrogen all the time. And again the city researchers
- 18:59Speaker 1: Philip Morris and just set be um and I know
- 19:04Speaker 1: it's Philip Morrison. I was just making a show, a
- 19:07Speaker 1: tobacco joke. They have their hands and everything. Um. Since
- 19:11Speaker 1: these guys said they would probably transmit somewhere on the
- 19:16Speaker 1: radio spectrum, um, and they would probably be familiar with
- 19:21Speaker 1: radio spectrums and electromagnetism, they would also probably know, just
- 19:25Speaker 1: like we just figured out, that the most common frequency
- 19:29Speaker 1: in the entire universe, no matter where you are, mega hurts.
- 19:33Speaker 1: So maybe this would be a really good place to
- 19:36Speaker 1: listen out for alien radio transmissions. That's right, and the
- 19:40Speaker 1: wild signal was broadcast at four point four or five
- 19:45Speaker 1: five six mega hurts right in the middle of the
- 19:48Speaker 1: hydrogen line, right on the most common frequency in the
- 19:53Speaker 1: entire universe. We found in nineteen seven radio transmission that
- 19:58Speaker 1: was thirty times strong or than the normal background noise
- 20:03Speaker 1: on that frequency. That's right, and that makes uh made
- 20:06Speaker 1: scientists go holy cow or wow. That even made skeptics go, oh,
- 20:12Speaker 1: but what's this all about? Exactly the shape of it,
- 20:16Speaker 1: like we talked about the pyramid shape, um, is exactly
- 20:19Speaker 1: what you would expect. So that made everyone sit up
- 20:22Speaker 1: and go all right, well there's also that. And then
- 20:25Speaker 1: the sharpness, I know is the third big reason that
- 20:28Speaker 1: it just doesn't fit in right or it does fit
- 20:31Speaker 1: in as an alien transmission. So there are tons of
- 20:33Speaker 1: like um, very powerful bursts here. They're radio transmissions like quasars,
- 20:39Speaker 1: emit um radio transmissions and UM satellites. There's well, there's
- 20:45Speaker 1: a lot of natural ones. I mean the natural ones
- 20:48Speaker 1: that are very messy. They get spread across the band,
- 20:52Speaker 1: the electromagnetic pants. So um, if you got like a
- 20:56Speaker 1: burst from like a quasar or something like that, you
- 20:59Speaker 1: found it through the big year, you're going to it's
- 21:02Speaker 1: gonna turn up on say like channel fourteen forty four,
- 21:06Speaker 1: it's going to spill over across the band. They're very messy.
- 21:10Speaker 1: One of the things that really makes the Wild signals
- 21:13Speaker 1: so significant is that it was um tuned. Basically, it
- 21:19Speaker 1: appears to have been tuned because it came through only
- 21:22Speaker 1: on the fourteen frequency. It didn't spill over, and the
- 21:26Speaker 1: Big Year was listening to fifty channels. So imagine like
- 21:30Speaker 1: your radio is tuned, or you have fifty radios tuned
- 21:32Speaker 1: to and so on right up to fourteen whatever that
- 21:41Speaker 1: goes to fifty channels out Um, the wild signal only
- 21:45Speaker 1: came through on the fouency right then, So you've got
- 21:48Speaker 1: the sharpness, You've got the fact that it was right
- 21:50Speaker 1: in the middle of the hydrogen line, you have that
- 21:52Speaker 1: pyramid shape, and everyone is wondering what the heck is
- 21:55Speaker 1: going on? And uh, right after this message, we will
- 21:58Speaker 1: talk about a few reasons why I may not be
- 22:01Speaker 1: an alien transmission. All right, So we've made a bit
- 22:18Speaker 1: of a case that there's something hinky that happened on
- 22:21Speaker 1: August seven, Right, Yeah, I think so pretty strong case. Um.
- 22:29Speaker 1: Of course, when you make a case like this, it's
- 22:32Speaker 1: like they say, extraordinary claims require extraordinary evidence. Basically, what
- 22:36Speaker 1: we've ended up with is this is some evidence. So
- 22:40Speaker 1: you can't make like a full claim that hey, this
- 22:43Speaker 1: is definitely an alien trying to get in touch with us,
- 22:45Speaker 1: because all we have is that SEV burst. We haven't
- 22:49Speaker 1: been able to find it since then. Uh, and we've
- 22:52Speaker 1: looked or listened, right, and just attending in an unexplained
- 22:56Speaker 1: radio signal doesn't I mean, it's just it's not like
- 23:00Speaker 1: the signal said, hey, we're broadcasting to you live from
- 23:04Speaker 1: Kepler forty three B. We'll be seeing you guys in
- 23:09Speaker 1: a dr when we come down and take over your
- 23:12Speaker 1: planets can be a bad day for you. Um. Yeah,
- 23:15Speaker 1: So there's like you said, that it's not in and
- 23:18Speaker 1: of itself approven alien signal. But um, there are a
- 23:22Speaker 1: lot of really unexplainable things that support the idea that
- 23:26Speaker 1: that's potentially possible. There are a lot of people who
- 23:29Speaker 1: have tried to put out explanations to the contrary. Right.
- 23:33Speaker 1: For one, they have gone back and listened to that
- 23:37Speaker 1: same patch of sky over and over again more than
- 23:40Speaker 1: a hundred times, and no one's ever picked up the
- 23:42Speaker 1: wild signal again. Yeah, and I have sure it would
- 23:46Speaker 1: be nice to go back to that same patch of
- 23:48Speaker 1: sky and hear it again. But if it takes a
- 23:51Speaker 1: lot of energy to beam a signal like that from
- 23:53Speaker 1: deep space it may have been a one off or um.
- 23:57Speaker 1: Some people have theorized that maybe if you were an
- 24:00Speaker 1: alien civilization, it takes so much power to broadcast in
- 24:04Speaker 1: every direction, you might use more of a lighthouse sweeping method, um.
- 24:08Speaker 1: And so it wouldn't be at that fixed point, you know,
- 24:11Speaker 1: it's just out there moving across the sky, right and um,
- 24:14Speaker 1: it just so happens that the big ear and this
- 24:17Speaker 1: lighthouse radio beacon crossed one another the same Yeah, it's
- 24:23Speaker 1: just the right time. Um. Yeah, that is a pretty
- 24:26Speaker 1: good counter explanation or counter argument to that one. Another
- 24:29Speaker 1: one was that it was, um, it was some sort
- 24:33Speaker 1: of transmission from Earth projected and reflected off of like
- 24:38Speaker 1: a piece of space debris. There's a lot of junk
- 24:40Speaker 1: out in space. You've seen gravity. I've seen gravity. There's
- 24:44Speaker 1: a lot of space junk out there, and it can
- 24:46Speaker 1: reflect radio signals. Right. But there's some real problems with
- 24:50Speaker 1: that explanation as well. Yeah, because I believe that from
- 24:54Speaker 1: Earth we we don't transmit on the hydrogen line, correct, right,
- 24:59Speaker 1: it's protected, like you're not allowed to transmit on that
- 25:01Speaker 1: because people are listening out for aliens on that line.
- 25:05Speaker 1: So no bounce back. No, So even if you do
- 25:07Speaker 1: have one jerk whose sole purpose in life is to
- 25:11Speaker 1: mess with SETI scientists by beaming radio signals at twenty
- 25:16Speaker 1: mega hurts um so that they'll get beam back into space.
- 25:21Speaker 1: Even if there was somebody transmitting and it it's supposedly
- 25:24Speaker 1: bounced off a space junk, there's still problems with that explanation.
- 25:29Speaker 1: To Chiefly, the space junk would have to be moving
- 25:34Speaker 1: in the same direction at the exact same rate as
- 25:37Speaker 1: Earth in order to give the illusion that it was
- 25:40Speaker 1: coming from a fixed point in outer space, because remember,
- 25:45Speaker 1: the Earth would actually it would have to it would
- 25:48Speaker 1: have to be even more mind boggling and perfect than that.
- 25:52Speaker 1: It would have to be moving at a rate that
- 25:54Speaker 1: allowed the Earth to pass by it over the course
- 25:58Speaker 1: of seventy two seconds. It couldn't just be moving at
- 26:01Speaker 1: the same rate or else the bigger exactly so um.
- 26:06Speaker 1: Apparently Jerry Ahman was a skeptic of his own WOW signal,
- 26:10Speaker 1: and even he was like this, no, that the space debriefing,
- 26:15Speaker 1: It's just that probability of everything lining up like that
- 26:20Speaker 1: is just so um small that I hereby dismissed that
- 26:26Speaker 1: that's what he did and uh, here's the thing. A
- 26:29Speaker 1: few years later, I think in nine actually develop the
- 26:32Speaker 1: capability for this big year uh, and then other radio
- 26:35Speaker 1: telescopes to move on their own. UM. So, in other words,
- 26:39Speaker 1: if it would have locked onto that signal, it could
- 26:41Speaker 1: have locked on and then counteracted the rotation of the
- 26:44Speaker 1: Earth and really listened to see how long that thing lasted. Yeah,
- 26:47Speaker 1: because we have no idea how long it lasted. We
- 26:49Speaker 1: know it lasted at least seventy two seconds, but no
- 26:52Speaker 1: more than twenty four hours because it wasn't there the
- 26:55Speaker 1: day before, and it wasn't there the day after when
- 26:57Speaker 1: the Big Year went through and swept past the same
- 27:00Speaker 1: the same patch of sky. UM. So the data believe me, Yes,
- 27:06Speaker 1: they did UM. And like we said, they started listening
- 27:08Speaker 1: for it, specifically UM the very large array the v
- 27:13Speaker 1: l A in the mid nineties, and that is is
- 27:16Speaker 1: that in New Mexico. I think, uh, yeah, New Mexico
- 27:20Speaker 1: UM that has the power of twenty seven separate radio
- 27:24Speaker 1: antenna's UM a hundred times more sensitive than the Big Year.
- 27:28Speaker 1: And they specifically UM. This guy named Robert Gray, an
- 27:32Speaker 1: amateur astronomer, went looking for it, pointed it towards Sagittarius,
- 27:36Speaker 1: which is sort of the rough direction that the wild
- 27:39Speaker 1: signal came from. And again he's like, I haven't heard
- 27:42Speaker 1: anything since then. Um, well then, and that's another point
- 27:46Speaker 1: that a lot of people say it was nothing, is
- 27:49Speaker 1: that the that point out in deep space, out in
- 27:52Speaker 1: the sky. There's nothing there, right, There's no planet, there's
- 27:56Speaker 1: no star, there's no nothing. So what what is some
- 28:01Speaker 1: seemingly artificial radio transmission being broadcast from when there's nothing
- 28:05Speaker 1: but space out there? Pretty weird? It is very weird.
- 28:09Speaker 1: But again, every argument that's been made has been Uh,
- 28:15Speaker 1: you can make a counter argument to an irrational reasonable one.
- 28:18Speaker 1: So where are we saying that there that this was
- 28:22Speaker 1: an alien transmission? Not necessarily, but it is still potentially
- 28:28Speaker 1: a reasonable explanation given the the evidence that the Wow
- 28:33Speaker 1: signal presents. Yeah, I think, um, the way I like
- 28:37Speaker 1: looking at it is what Jerry Aiman said, Um sometimes
- 28:40Speaker 1: in the eighties he says, the best way I can
- 28:41Speaker 1: think of it is that it was a tug on
- 28:44Speaker 1: the cosmic fishing line. Doesn't prove that you have a
- 28:46Speaker 1: fish on the line, but it does suggest it if
- 28:48Speaker 1: you keep your line in the water at that spot,
- 28:50Speaker 1: you might get a fish. So I don't know necessarily
- 28:53Speaker 1: about that spot, but it was it was something that
- 28:55Speaker 1: we can't quite explain. And um, you know, keep the
- 29:00Speaker 1: very large array going, like, keep listening, keep watching the
- 29:03Speaker 1: skis skies. Um, you got anything else? Do we miss anything? Oh? Man,
- 29:11Speaker 1: we could go on about ceti and all that stuff
- 29:14Speaker 1: for days. Maybe we will someday. I think the official
- 29:17Speaker 1: skeptics um line is that what did they finally say?
- 29:23Speaker 1: They like, it's a the Skeptics Club. Yeah, the Skeptics Club,
- 29:27Speaker 1: they said, uh oh, an interstellar radio source of unknown
- 29:31Speaker 1: origin is the official line. So the Skeptics Club A
- 29:36Speaker 1: big shrug of the shoulders essentially. Yeah, so who knows?
- 29:40Speaker 1: Six e q U J five pretty remarkable. I'll bet
- 29:44Speaker 1: somebody has that tattooed on them somewhere. I bet he
- 29:46Speaker 1: spit oh yeah, totally, like on the back of their neck. Um.
- 29:49Speaker 1: I bet Jerry Amin like spit his coffee all over
- 29:51Speaker 1: the paper too, you know, did a big spit take. Yeah, uh, classic, totally.
- 30:00Speaker 1: He's like the Jerry Lewis of astronomers. Uh. If you
- 30:06Speaker 1: want to know more about Jerry Lewis or the Wow
- 30:08Speaker 1: signal or anything like that, you can type some words
- 30:11Speaker 1: like six e q U J five in the search
- 30:15Speaker 1: bar at how stuff works dot com. And since I
- 30:18Speaker 1: said search bar, it's time for a listener mail. I'm
- 30:22Speaker 1: gonna call this purpose of life. We've got a lot
- 30:25Speaker 1: of great responses from does the Body replace Itself? When
- 30:28Speaker 1: you went into that really nice philosophical um sidebar on
- 30:33Speaker 1: like why are we here? I thought it was interesting. Um. Hey, guys,
- 30:37Speaker 1: just finished my four month binge of all seven hundred
- 30:40Speaker 1: plus episodes of stuff you should know you wanted to
- 30:43Speaker 1: write in about does the Body replace itself? Towards the end,
- 30:46Speaker 1: you discuss the purpose of life and why there can't
- 30:49Speaker 1: be just a one or a few species. Uh. If
- 30:51Speaker 1: the purpose of life is two cycle carbon et cetera,
- 30:55Speaker 1: speaking as a geologist biologist, the Earth doesn't need life
- 30:58Speaker 1: for anything. The planet would be just fine with no
- 31:01Speaker 1: life and no carbon cycling. It would just look quite
- 31:04Speaker 1: a bit different. Uh. Talking about the purpose of life
- 31:08Speaker 1: like this is an easy and common fallacy that implies
- 31:11Speaker 1: some need that's being filled. A life's purpose, if you
- 31:14Speaker 1: want to call it, that is simply to replicate itself.
- 31:18Speaker 1: That is, at some point there was a molecule able
- 31:20Speaker 1: to replicate itself as it did that some copies were
- 31:24Speaker 1: better at replicating than others, and so on and so on.
- 31:27Speaker 1: Over time, it became more effective to be encased in
- 31:30Speaker 1: a membrane uh than to use d N A. Then
- 31:33Speaker 1: to use DNA instead of RNA, and so on and
- 31:36Speaker 1: so on. Everything a lot today shares the history of
- 31:38Speaker 1: ancestors that replicated and passed on their genes successfully. Life
- 31:42Speaker 1: doesn't need to live or die, or eat or breathe
- 31:46Speaker 1: or swim or fly or photosynthesize or procreate or think
- 31:49Speaker 1: or love, but it does those things because they help
- 31:53Speaker 1: it effectively copy and pass on the genes. This is
- 31:57Speaker 1: the fundamental purpose of life. And though some may think
- 31:59Speaker 1: it's cynical or heartless, I find it beautiful and truly awesome.
- 32:04Speaker 1: And that is Danny in Seattle. Thanks a lot, Danny Seattle.
- 32:07Speaker 1: All the atheists and agnostics out there, right, I just
- 32:10Speaker 1: posted a thing. They have like seven percent more agnostics
- 32:15Speaker 1: and atheists than the rest of the country, really and
- 32:18Speaker 1: seven that's pretty significant, and less identify as Christian than
- 32:23Speaker 1: the rest of the country. So there's a bunch of
- 32:26Speaker 1: godless freaks. Well, thanks Danny for tossing your O pining
- 32:31Speaker 1: in about the purpose of life or the purposelessness of life. Uh.
