1
00:00:03,800 --> 00:00:06,680
Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff

2
00:00:06,680 --> 00:00:13,640
Speaker 1: Works dot com. Hey, you're welcome to Stuff to Blow

3
00:00:13,720 --> 00:00:15,560
Speaker 1: your Mind. My name is Robert Lamb and my name

4
00:00:15,640 --> 00:00:18,239
Speaker 1: is Julie Tuglass. And this is part two of our

5
00:00:18,400 --> 00:00:23,200
Speaker 1: steady episode the Search for Extraterrestrial Intelligence. This again, this

6
00:00:23,280 --> 00:00:25,840
Speaker 1: is part two. I highly recommend you listen to part

7
00:00:25,880 --> 00:00:28,160
Speaker 1: one first. Sometimes when we do a part one in

8
00:00:28,200 --> 00:00:29,560
Speaker 1: a part two, you can kind of take them in

9
00:00:29,600 --> 00:00:32,319
Speaker 1: any order you want, But this is not the case here. Uh,

10
00:00:32,360 --> 00:00:36,440
Speaker 1: there's a definite, uh narrative structure in place, and uh,

11
00:00:36,840 --> 00:00:38,400
Speaker 1: it just won't make sense if you don't listen to

12
00:00:38,440 --> 00:00:40,800
Speaker 1: part one first. That's right. We created the setup so

13
00:00:40,840 --> 00:00:42,839
Speaker 1: that when we get to this part that you guys

14
00:00:42,880 --> 00:00:44,600
Speaker 1: have a little bit more of an understanding of the

15
00:00:44,680 --> 00:00:47,320
Speaker 1: context of exp planets and aliens. So I hope you

16
00:00:47,360 --> 00:00:53,440
Speaker 1: guys enjoy Part two. Yeah, we're talking about set, we're

17
00:00:53,440 --> 00:00:57,920
Speaker 1: talking about the possibility of intelligent alien life elsewhere in

18
00:00:57,960 --> 00:01:01,600
Speaker 1: the cosmos, and we're talking about radio waves. I thought

19
00:01:01,600 --> 00:01:03,920
Speaker 1: it's important to point out that there's a reason why

20
00:01:04,040 --> 00:01:06,800
Speaker 1: why radio waves are so important in all of this. Uh.

21
00:01:06,840 --> 00:01:10,280
Speaker 1: In Nidograsse Tyson's book Space chronicles. He points out that

22
00:01:10,760 --> 00:01:15,200
Speaker 1: radio waves are a communication band of choice for potential

23
00:01:15,200 --> 00:01:18,480
Speaker 1: alien civilizations due to the radio waves ability to traverse

24
00:01:18,600 --> 00:01:24,240
Speaker 1: the galaxy unimpended by interstellar gas and dust clouds really well,

25
00:01:24,360 --> 00:01:26,560
Speaker 1: travel really well. So it's it's something we can look

26
00:01:26,560 --> 00:01:29,800
Speaker 1: for that we know travels vast distances and again, and

27
00:01:29,800 --> 00:01:31,840
Speaker 1: and that's the one of the things that we as

28
00:01:31,840 --> 00:01:33,920
Speaker 1: we mentioned when we're talking about firm and paradox and

29
00:01:33,959 --> 00:01:36,640
Speaker 1: the Drake equation, is that when we're talking about finding

30
00:01:36,680 --> 00:01:40,680
Speaker 1: life elsewhere in the universe, we're talking vast stretches of

31
00:01:40,840 --> 00:01:43,200
Speaker 1: time and space, I mean to to the level that

32
00:01:43,240 --> 00:01:46,320
Speaker 1: it's really difficult for us to to think about it. Uh,

33
00:01:46,400 --> 00:01:48,559
Speaker 1: you know, like it's it's like thinking about thinking about

34
00:01:48,560 --> 00:01:50,280
Speaker 1: in terms of like finding your soul mate. It's like

35
00:01:50,680 --> 00:01:53,600
Speaker 1: that that person is out there in the world and

36
00:01:53,600 --> 00:01:56,200
Speaker 1: they're alive, and they didn't exist, you know, you know,

37
00:01:56,240 --> 00:01:58,240
Speaker 1: five thousand years ago, and it's it's not a situation

38
00:01:58,240 --> 00:02:01,000
Speaker 1: where they won't exist for another five Imagine that you're

39
00:02:01,040 --> 00:02:03,240
Speaker 1: super picky, and so you kind of have to apply

40
00:02:03,360 --> 00:02:06,160
Speaker 1: that Drake equation to your soul mate, right, so like

41
00:02:06,200 --> 00:02:10,480
Speaker 1: they have to be like exactly like five ten and

42
00:02:10,560 --> 00:02:13,880
Speaker 1: three quarter inches and they have to be I don't

43
00:02:13,880 --> 00:02:17,079
Speaker 1: know how many more like constraints can you put on that, right,

44
00:02:17,120 --> 00:02:19,640
Speaker 1: you could put like a hundred million constraints on it.

45
00:02:19,720 --> 00:02:22,640
Speaker 1: And that is what it's like searching for that signal.

46
00:02:23,040 --> 00:02:26,840
Speaker 1: So steady the search for extraterrestial intelligence. There's the Study

47
00:02:26,919 --> 00:02:30,640
Speaker 1: Agency and this was set up in the sixties in

48
00:02:30,760 --> 00:02:34,920
Speaker 1: Earnest by dedicated astronomers who are trying to figure this out.

49
00:02:35,080 --> 00:02:38,720
Speaker 1: Could they really pick up a signal? Now the search

50
00:02:38,800 --> 00:02:42,440
Speaker 1: uses large radio telescopes and with these telescope, scientists involved

51
00:02:42,440 --> 00:02:45,800
Speaker 1: in the STEADY hope to detect radio signals that are leaking.

52
00:02:45,960 --> 00:02:49,639
Speaker 1: This is what we're thinking leaking from other intelligent civilizations,

53
00:02:49,800 --> 00:02:54,520
Speaker 1: or that other civilizations have specifically aimed that signal at us. Yeah,

54
00:02:54,560 --> 00:02:58,080
Speaker 1: so either we'll listen in on on an alien phone

55
00:02:58,080 --> 00:03:01,680
Speaker 1: call essentially, or we will risk eve that alien phone

56
00:03:01,680 --> 00:03:05,040
Speaker 1: call that we both hope and dreadful. Now, according to

57
00:03:05,040 --> 00:03:08,400
Speaker 1: Marshall Brain, he is the founder of Hastaff Works, He's

58
00:03:08,440 --> 00:03:10,440
Speaker 1: got a nice blog post on this. He says, the

59
00:03:10,480 --> 00:03:14,559
Speaker 1: problem with steady is that it requires massive computational resources

60
00:03:14,600 --> 00:03:16,720
Speaker 1: because think of all that data that you have to

61
00:03:16,760 --> 00:03:20,239
Speaker 1: comb through Study is listening to a huge number of frequencies.

62
00:03:20,240 --> 00:03:22,919
Speaker 1: Then the computer has to look at each frequency separately

63
00:03:22,919 --> 00:03:25,560
Speaker 1: and try to decide if it's carrying an intelligent signal

64
00:03:25,560 --> 00:03:27,920
Speaker 1: as opposed to noise. To give you an idea of

65
00:03:27,919 --> 00:03:30,359
Speaker 1: the scope of the problem, the antenna used by Study

66
00:03:30,440 --> 00:03:34,720
Speaker 1: at Home records thirty five gigabytes of data every day.

67
00:03:34,840 --> 00:03:37,960
Speaker 1: It takes millions of hours of computation time just to

68
00:03:38,040 --> 00:03:40,560
Speaker 1: process one day's worth of data. Now he's talking about

69
00:03:40,560 --> 00:03:42,960
Speaker 1: a program that's called Study at Home that sort of

70
00:03:43,360 --> 00:03:47,080
Speaker 1: runs the data for you in the background. Yeah. Yeah,

71
00:03:47,160 --> 00:03:50,000
Speaker 1: the distributed computing program where you would install this on

72
00:03:50,040 --> 00:03:51,880
Speaker 1: your home computer. You could have to go use the

73
00:03:51,920 --> 00:03:54,640
Speaker 1: restroom or you go to have lunch or whatever. Screensaver

74
00:03:54,760 --> 00:03:57,800
Speaker 1: kicks in and your computer instead of working on your

75
00:03:57,800 --> 00:04:00,240
Speaker 1: own you know, efforts in your word, process a thing

76
00:04:00,320 --> 00:04:02,760
Speaker 1: or what have you, It then contributes that computing power

77
00:04:02,880 --> 00:04:06,720
Speaker 1: to studies problem of analyzing all of this data. That's right.

78
00:04:06,720 --> 00:04:10,040
Speaker 1: It grinds away on that data, which is really cool. So, uh,

79
00:04:10,160 --> 00:04:12,360
Speaker 1: the other problem, I guess you could say the problem

80
00:04:12,360 --> 00:04:14,920
Speaker 1: of having so much data is, uh, you know, trying

81
00:04:14,960 --> 00:04:20,080
Speaker 1: to tune into the most probable frequencies. So one way

82
00:04:20,120 --> 00:04:23,040
Speaker 1: to go about this is to determine the best range,

83
00:04:23,279 --> 00:04:25,839
Speaker 1: and the one to tend giga hurt range is the

84
00:04:25,839 --> 00:04:29,279
Speaker 1: best range to listen is the quietest. Study also uses

85
00:04:29,400 --> 00:04:33,080
Speaker 1: large multi channel bandwidth signal processors that can scan millions

86
00:04:33,200 --> 00:04:36,919
Speaker 1: or billions of frequencies uh simultaneously, and that's really what's

87
00:04:37,040 --> 00:04:40,040
Speaker 1: what they're more leaning towards these days. Yeah, and then

88
00:04:40,200 --> 00:04:41,600
Speaker 1: there are so many factors you have to take into

89
00:04:41,600 --> 00:04:43,360
Speaker 1: account to you have to you have to worry about

90
00:04:43,920 --> 00:04:47,120
Speaker 1: about waves that are actually emitted by us, that are

91
00:04:47,160 --> 00:04:50,360
Speaker 1: just bouncing back from from something else, say, you know,

92
00:04:50,520 --> 00:04:54,360
Speaker 1: a piece of space garbage, even um pulsars to pulsars,

93
00:04:54,360 --> 00:04:56,440
Speaker 1: because that was a big one. Yeah, the pulsars are

94
00:04:56,480 --> 00:04:59,280
Speaker 1: sending out this signal, this pulse, and when we first

95
00:04:59,760 --> 00:05:01,440
Speaker 1: just governed them, we didn't know what they were. They're like,

96
00:05:01,440 --> 00:05:03,760
Speaker 1: oh my goodness, this is it, this, this could be it.

97
00:05:04,200 --> 00:05:05,880
Speaker 1: And then we we looked a little deeper when we've

98
00:05:05,880 --> 00:05:07,920
Speaker 1: realized that will actually there are these things and we'll

99
00:05:07,920 --> 00:05:10,680
Speaker 1: call them pul stars because they're pulsing starts start exactly

100
00:05:10,680 --> 00:05:13,560
Speaker 1: stars emitting a pulls um. And I also wanted to

101
00:05:13,600 --> 00:05:16,400
Speaker 1: mention too that most of study research has been done

102
00:05:16,440 --> 00:05:19,600
Speaker 1: by renting time on existing radio telescope, So it's not

103
00:05:19,680 --> 00:05:23,200
Speaker 1: even something that's in an endeavor that we can do constantly. Right,

104
00:05:23,240 --> 00:05:26,040
Speaker 1: you have to rent the time because it's super expensive

105
00:05:26,200 --> 00:05:30,440
Speaker 1: to to even get this sort of technology, uh for

106
00:05:30,480 --> 00:05:35,039
Speaker 1: your own devices, right. Yeah. And it's a nonprofit and

107
00:05:35,040 --> 00:05:38,240
Speaker 1: they depend on the funding from a variety of different sources.

108
00:05:38,520 --> 00:05:41,359
Speaker 1: NASA UM kicks in and as well as you know,

109
00:05:41,400 --> 00:05:44,320
Speaker 1: even just you know, individuals and various groups out there

110
00:05:44,400 --> 00:05:47,640
Speaker 1: contribute to the steady effort because it's something that's it's

111
00:05:47,839 --> 00:05:48,960
Speaker 1: you know a lot of people will leaeve in it,

112
00:05:49,000 --> 00:05:51,120
Speaker 1: and for good reason, because it is if you if

113
00:05:51,120 --> 00:05:53,880
Speaker 1: you consider the even the possibility that there's life out

114
00:05:53,920 --> 00:05:56,760
Speaker 1: there in the universe, then it's it's it's essential that

115
00:05:56,800 --> 00:05:59,240
Speaker 1: we find out what it is and what it might

116
00:05:59,240 --> 00:06:03,360
Speaker 1: consist of. Yep. And the three main radio telescopes are

117
00:06:03,400 --> 00:06:07,360
Speaker 1: the Parks Radio Telescope in Australia. Uh, there's the telescope

118
00:06:07,360 --> 00:06:10,680
Speaker 1: in green Bank, West Virginia and the r CEBO Radio

119
00:06:10,680 --> 00:06:12,880
Speaker 1: Telescope in Puerto Rico. And I believe that's the one

120
00:06:12,920 --> 00:06:15,600
Speaker 1: that was in the movie Contact. Yes, at least in

121
00:06:15,640 --> 00:06:19,080
Speaker 1: the intro stuff. Yeah, and of course SETTI continues to

122
00:06:19,400 --> 00:06:22,160
Speaker 1: evolve with the times. A laser technology has made it

123
00:06:22,200 --> 00:06:25,880
Speaker 1: possible to search the optical portion of the electromatetics spectrum

124
00:06:25,920 --> 00:06:28,479
Speaker 1: for pulses of laser light that are just a few

125
00:06:28,640 --> 00:06:32,080
Speaker 1: nanoseconds long and duration so short you have to really

126
00:06:32,200 --> 00:06:34,680
Speaker 1: fine tune it to to actually you know, record them

127
00:06:34,680 --> 00:06:38,839
Speaker 1: and analyze them. But during that nanosecond they can actually

128
00:06:38,920 --> 00:06:42,000
Speaker 1: briefly shine brighter than the light of nearby stars. So

129
00:06:42,160 --> 00:06:44,839
Speaker 1: there's just another area set he's looking for the possible

130
00:06:44,839 --> 00:06:48,720
Speaker 1: clues and trying to intercept that phone call. Yeah, and

131
00:06:48,760 --> 00:06:52,000
Speaker 1: just to give everybody an idea of friendly, how how

132
00:06:52,720 --> 00:06:55,680
Speaker 1: huge this is, this this um this idea of trying

133
00:06:55,680 --> 00:06:58,479
Speaker 1: to pick up this particular signal. Uh. There are a

134
00:06:58,520 --> 00:07:00,560
Speaker 1: couple of different ways to go at at. One is

135
00:07:00,600 --> 00:07:03,680
Speaker 1: called the wide field search. So you have this expansive

136
00:07:04,040 --> 00:07:06,240
Speaker 1: sky beyond right, what do you do? I mean, that's

137
00:07:06,440 --> 00:07:08,840
Speaker 1: a ton of data that's coming at you at any

138
00:07:08,880 --> 00:07:12,920
Speaker 1: little point that you decide to concentrate on. So with

139
00:07:12,960 --> 00:07:15,520
Speaker 1: the wide field search and this method, you survey large

140
00:07:15,600 --> 00:07:19,080
Speaker 1: chunks of the sky for one at a time for signals,

141
00:07:19,600 --> 00:07:22,000
Speaker 1: and it allows the entire sky to be searched at

142
00:07:22,000 --> 00:07:24,280
Speaker 1: a low resolution for short period of time. The problem

143
00:07:24,320 --> 00:07:26,400
Speaker 1: is the low resolution, right, But if you get some

144
00:07:26,480 --> 00:07:28,320
Speaker 1: data back that says, hey, this seems kind of like

145
00:07:28,320 --> 00:07:31,720
Speaker 1: a hot area, then can go back later with high resolution.

146
00:07:31,800 --> 00:07:35,240
Speaker 1: That's the idea at least, and then you have targeted searches.

147
00:07:35,320 --> 00:07:39,080
Speaker 1: And this method you make intensive investigations of a limited

148
00:07:39,160 --> 00:07:41,920
Speaker 1: number of sunlike stars. So again that's that sort of

149
00:07:42,000 --> 00:07:45,600
Speaker 1: Goldilocks area that you would be looking for. And the

150
00:07:45,600 --> 00:07:48,800
Speaker 1: targeted search allows more detailed investigations of small areas that

151
00:07:48,840 --> 00:07:53,000
Speaker 1: we think might be probable locations of e T. Now

152
00:07:53,280 --> 00:07:57,560
Speaker 1: what what happens if you think you've heard a signal, Well,

153
00:07:57,640 --> 00:08:00,400
Speaker 1: then you have to analyze that signal. You just run

154
00:08:00,440 --> 00:08:02,320
Speaker 1: to the press and say we got it, we got

155
00:08:02,320 --> 00:08:05,640
Speaker 1: it here that we just they said, they just totally

156
00:08:05,640 --> 00:08:09,080
Speaker 1: morse coded us um from the article has study works

157
00:08:09,120 --> 00:08:12,040
Speaker 1: on on hastaf works dot com. If a signal detected,

158
00:08:12,080 --> 00:08:14,200
Speaker 1: there are a series of steps that follow to confirm

159
00:08:14,240 --> 00:08:17,720
Speaker 1: that signal is extraterrestrial. First, the radio telescope is moved

160
00:08:17,760 --> 00:08:21,080
Speaker 1: off the target. The signal should go away, right, and

161
00:08:21,080 --> 00:08:23,480
Speaker 1: then it should return When the telescope is pointed back.

162
00:08:23,480 --> 00:08:25,120
Speaker 1: So they come and say, let's just make sure that

163
00:08:25,160 --> 00:08:28,600
Speaker 1: this is the real deal, move this off access and

164
00:08:28,640 --> 00:08:31,600
Speaker 1: then take it back. UH. Known Earth or Near Earth's

165
00:08:32,040 --> 00:08:35,840
Speaker 1: sources such as satellites must be ruled out stuff that's

166
00:08:36,080 --> 00:08:40,320
Speaker 1: originating from that object or bouncing back from you know,

167
00:08:40,360 --> 00:08:44,719
Speaker 1: Earth signal bouncing back off that object. Similarly, quasars pulsars

168
00:08:44,760 --> 00:08:47,160
Speaker 1: have to be ruled out as well, and then the

169
00:08:47,200 --> 00:08:51,040
Speaker 1: signal has to be confirmed by another radio telescope, preferably

170
00:08:51,040 --> 00:08:53,440
Speaker 1: one on a different continent to say, are you guys

171
00:08:53,440 --> 00:08:56,960
Speaker 1: hearing the same thing that we are hearing? UM? All right,

172
00:08:57,080 --> 00:09:00,760
Speaker 1: so so far we don't. We haven't really had that contact.

173
00:09:00,840 --> 00:09:04,000
Speaker 1: But in nineteen seventies seven there's something called the Wow

174
00:09:04,240 --> 00:09:07,760
Speaker 1: signal that was detected, and this got people really excited

175
00:09:07,800 --> 00:09:12,680
Speaker 1: because it is still an anomaly. It's certainly the seventy

176
00:09:12,679 --> 00:09:16,199
Speaker 1: two second signals something that that seems to be something

177
00:09:16,600 --> 00:09:20,040
Speaker 1: that was picked up by the big Ear radio telescope

178
00:09:20,240 --> 00:09:23,959
Speaker 1: in Ohio just outside of Delaware, UM and the main

179
00:09:24,000 --> 00:09:27,840
Speaker 1: astronomer and all of this American astronomer Jerry ruh Emon

180
00:09:28,520 --> 00:09:31,679
Speaker 1: PhD and UH, and he's even kind of gone back

181
00:09:31,720 --> 00:09:33,880
Speaker 1: and forth on it. Um. I was reading some of

182
00:09:33,920 --> 00:09:36,079
Speaker 1: his writings about it, and like for a while he

183
00:09:36,160 --> 00:09:38,440
Speaker 1: was he was just he was of the mindset, now

184
00:09:38,520 --> 00:09:41,119
Speaker 1: there's got to be a you know, a terrestrial explanation

185
00:09:41,200 --> 00:09:43,640
Speaker 1: for this and what have you. But on the thirtieth

186
00:09:43,640 --> 00:09:46,839
Speaker 1: anniversary of the Wow signal, he had this, uh, this

187
00:09:47,000 --> 00:09:49,199
Speaker 1: really cool bit to say. I'm just gonna read the

188
00:09:49,280 --> 00:09:52,359
Speaker 1: quote here. He says, Thus, since all of the possibilities

189
00:09:52,360 --> 00:09:54,800
Speaker 1: of the terrestrial origin have been either ruled out or

190
00:09:54,800 --> 00:09:58,040
Speaker 1: seemed improbable, and since the possibility of an extraterrestrial origin

191
00:09:58,320 --> 00:10:00,440
Speaker 1: has not been able to be ruled out, I must

192
00:10:00,480 --> 00:10:04,880
Speaker 1: conclude than an E. T. I extraterrestrial intelligence might the

193
00:10:04,960 --> 00:10:08,040
Speaker 1: MND is bolded and to tell us us UM might

194
00:10:08,120 --> 00:10:10,680
Speaker 1: have sent the the signal that we received as the

195
00:10:10,679 --> 00:10:13,280
Speaker 1: Wild Source. The fact that we saw the signal and

196
00:10:13,360 --> 00:10:15,360
Speaker 1: only one beam could be due to an E. T.

197
00:10:15,520 --> 00:10:17,960
Speaker 1: I sending a beacon signal in our direction and then

198
00:10:18,000 --> 00:10:21,440
Speaker 1: sending it in another direction that we couldn't detect. Of course,

199
00:10:21,440 --> 00:10:24,560
Speaker 1: being a scientist, I await the reception of additional signals

200
00:10:24,640 --> 00:10:27,000
Speaker 1: like the wild source that are able to be received

201
00:10:27,000 --> 00:10:30,800
Speaker 1: and analyzed by many observatories. Thus, I must state that

202
00:10:30,840 --> 00:10:32,760
Speaker 1: the origin of the wild signal is still an open

203
00:10:32,840 --> 00:10:35,480
Speaker 1: question for me. There's simply two little data to draw

204
00:10:35,640 --> 00:10:38,760
Speaker 1: many conclusions. In other words, as I stated above, I

205
00:10:38,840 --> 00:10:42,600
Speaker 1: choose not to quote draw vast conclusions from the half

206
00:10:42,760 --> 00:10:46,680
Speaker 1: vast data unquote. Yeah, there's this great quote too that

207
00:10:46,679 --> 00:10:48,240
Speaker 1: he says it was sort of like a tug on

208
00:10:48,280 --> 00:10:51,160
Speaker 1: the cosmic fishing line. So it doesn't prove that you

209
00:10:51,200 --> 00:10:52,680
Speaker 1: have a fish on the line, but it does say

210
00:10:52,720 --> 00:10:54,800
Speaker 1: that you should keep your line in the water because

211
00:10:54,800 --> 00:10:58,120
Speaker 1: there might be something there. And what is so mysterious

212
00:10:58,160 --> 00:11:00,200
Speaker 1: about the signal is that it was being in minted

213
00:11:00,280 --> 00:11:02,520
Speaker 1: from an area that was not a Goldilocks zone. It

214
00:11:02,559 --> 00:11:04,000
Speaker 1: was sort of the void. It was sort of like

215
00:11:04,160 --> 00:11:08,440
Speaker 1: there's nothing there, and they couldn't figure out like what

216
00:11:08,440 --> 00:11:11,840
Speaker 1: what was the what was originating, what was making that?

217
00:11:11,960 --> 00:11:15,480
Speaker 1: And a couple of really interesting theories came out of that,

218
00:11:16,480 --> 00:11:19,320
Speaker 1: which I think helped to sort of color our ideas

219
00:11:19,360 --> 00:11:22,360
Speaker 1: of why we haven't picked up a significant signal since

220
00:11:23,120 --> 00:11:26,960
Speaker 1: And that's this idea that that it was a lighthouse signal.

221
00:11:27,240 --> 00:11:28,880
Speaker 1: So rather than it just being like hey, and we're

222
00:11:28,920 --> 00:11:31,559
Speaker 1: just gonna send this universe the signal out into the

223
00:11:31,640 --> 00:11:35,120
Speaker 1: universe constantly. It was sort of like, we have limited

224
00:11:35,280 --> 00:11:38,600
Speaker 1: energy and resources and maybe even technology, and it's going

225
00:11:38,640 --> 00:11:40,160
Speaker 1: to be more of a lighthouse signal that just kind

226
00:11:40,200 --> 00:11:42,679
Speaker 1: of goes around and well, and that was one of

227
00:11:42,679 --> 00:11:44,520
Speaker 1: the ideas. Yeah, that Aimon mentioned the idea that it's

228
00:11:44,559 --> 00:11:47,160
Speaker 1: blasted this signal at Earth and then it turned blasted

229
00:11:47,160 --> 00:11:49,400
Speaker 1: in another direction, so we didn't get a heat signal

230
00:11:49,440 --> 00:11:51,520
Speaker 1: because it's you know, it's going in a circle or

231
00:11:51,520 --> 00:11:53,560
Speaker 1: what have you. It's it's it's trying to send out

232
00:11:53,559 --> 00:11:55,240
Speaker 1: the signal to anybody who might be out there and

233
00:11:55,320 --> 00:11:59,040
Speaker 1: letting them know, hey, what's up or or if if

234
00:11:59,080 --> 00:12:01,320
Speaker 1: it is. Indeed, and even with the true lighthouse saying

235
00:12:01,400 --> 00:12:04,880
Speaker 1: stay away because we have rocks or hideous monster gods

236
00:12:04,920 --> 00:12:07,640
Speaker 1: here and you should you shouldn't come anywhere near us. Well,

237
00:12:07,640 --> 00:12:10,120
Speaker 1: there is that zoo theory, right that that that we

238
00:12:10,240 --> 00:12:13,800
Speaker 1: have been picked up on and there's an intelligent extraterrest

239
00:12:13,840 --> 00:12:16,160
Speaker 1: fields out there. They're saying, hey, just let them do

240
00:12:16,240 --> 00:12:20,520
Speaker 1: their thing. We're just watch them from a distance like

241
00:12:20,559 --> 00:12:23,840
Speaker 1: a colony of ants and see what are up to um.

242
00:12:23,920 --> 00:12:26,400
Speaker 1: And then there's also the idea that maybe that technology

243
00:12:26,480 --> 00:12:30,880
Speaker 1: died or the technology from that society died out, or

244
00:12:31,000 --> 00:12:34,200
Speaker 1: maybe it's just that we didn't overlap. So in other words,

245
00:12:34,280 --> 00:12:37,400
Speaker 1: by the time that we started listening, we missed any

246
00:12:37,440 --> 00:12:39,320
Speaker 1: sort of signals that might have been sent out. Yeah,

247
00:12:39,360 --> 00:12:41,440
Speaker 1: I mean the whole thing that possibility, as well as

248
00:12:41,480 --> 00:12:43,880
Speaker 1: just the lighthouse possibility. It reminds me of any of

249
00:12:43,920 --> 00:12:46,280
Speaker 1: these movies where someone is stranded on a desert aisle

250
00:12:47,040 --> 00:12:49,439
Speaker 1: and that that plane flies over, and generally they're like

251
00:12:49,480 --> 00:12:51,240
Speaker 1: a sleep or doing something else. You're talking to a

252
00:12:51,320 --> 00:12:54,199
Speaker 1: volleyball when it happened planes flying over, and so they

253
00:12:54,240 --> 00:12:56,480
Speaker 1: frantically try and get that plane's attention, but it's too late.

254
00:12:56,480 --> 00:12:58,880
Speaker 1: It's already passed over. And maybe there just wasn't a

255
00:12:58,920 --> 00:13:00,560
Speaker 1: very good way to get its attention to begin with.

256
00:13:01,000 --> 00:13:03,600
Speaker 1: So there's this kind of like haunting feeling. What if

257
00:13:03,600 --> 00:13:06,240
Speaker 1: they did. What if that was an attempt at communication

258
00:13:06,360 --> 00:13:10,280
Speaker 1: from a distance civilization, and in one one way or another,

259
00:13:10,400 --> 00:13:12,640
Speaker 1: we were too late. We were just we we didn't

260
00:13:12,640 --> 00:13:15,520
Speaker 1: have the technology to respond or our our time the

261
00:13:15,559 --> 00:13:19,520
Speaker 1: time light line, or where the life cycle of our

262
00:13:19,559 --> 00:13:22,960
Speaker 1: civilizations didn't overlap, were can't overlap enough for that to

263
00:13:23,000 --> 00:13:25,040
Speaker 1: be possible. You know, it's like you know, it's like

264
00:13:25,160 --> 00:13:29,120
Speaker 1: star torn lovers out there in the cosmos. It's beautiful.

265
00:13:29,520 --> 00:13:32,160
Speaker 1: But that's what makes people so obsessed up about it

266
00:13:32,160 --> 00:13:34,319
Speaker 1: because they say, again, we've got the ingredients of this

267
00:13:34,360 --> 00:13:39,280
Speaker 1: primordial soup. There's got to be a possibility here. Um,

268
00:13:39,440 --> 00:13:42,040
Speaker 1: let's just keep listening. And that is what Study is

269
00:13:42,080 --> 00:13:45,440
Speaker 1: trying to do. And Study is not just listening. They're

270
00:13:45,440 --> 00:13:49,040
Speaker 1: preparing too. And we had mentioned this in a previous podcast,

271
00:13:49,120 --> 00:13:51,360
Speaker 1: guess about a couple of years ago, and I think

272
00:13:51,400 --> 00:13:53,559
Speaker 1: it was called Alien Etiquette one on one. Yeah, that

273
00:13:53,640 --> 00:13:55,040
Speaker 1: was one of the early ones that we did together.

274
00:13:55,640 --> 00:13:58,040
Speaker 1: They the Study Institute had a workshop in Paris in

275
00:13:58,080 --> 00:14:01,040
Speaker 1: two thousand and two inviting people from all different disciplines

276
00:14:01,080 --> 00:14:03,640
Speaker 1: to discuss the ways in which we might communicate with

277
00:14:03,679 --> 00:14:06,800
Speaker 1: aliens and the best modes to do it. And then

278
00:14:06,920 --> 00:14:09,800
Speaker 1: I really love this one. Two eight NASA sponsored a

279
00:14:09,840 --> 00:14:14,520
Speaker 1: course at the University of Wyoming called Interstellar Message Composition,

280
00:14:15,400 --> 00:14:18,520
Speaker 1: and UH students were asked to ponder how aliens might

281
00:14:18,559 --> 00:14:22,080
Speaker 1: communicate and how you would translate between languages and so

282
00:14:22,120 --> 00:14:24,120
Speaker 1: on and step forth. One of the students wrote a

283
00:14:24,160 --> 00:14:28,200
Speaker 1: poem about menstruation with syllables arranged in the Fibonacci sequence

284
00:14:28,800 --> 00:14:32,160
Speaker 1: in her quest, I think to try to let extraterdials

285
00:14:32,280 --> 00:14:34,640
Speaker 1: know about some of the human biology. Yeah, I mean,

286
00:14:34,680 --> 00:14:36,320
Speaker 1: because you never know what the talking points are going

287
00:14:36,360 --> 00:14:37,760
Speaker 1: to be. You want to be like, hey, do you

288
00:14:37,760 --> 00:14:39,680
Speaker 1: guys have ad menstruation and they're like, yeah, yeah, we

289
00:14:39,680 --> 00:14:41,840
Speaker 1: do actually, and then you have something to talk about

290
00:14:42,000 --> 00:14:44,400
Speaker 1: like oh, how quaint. Yeah, it's like a first date

291
00:14:44,480 --> 00:14:49,560
Speaker 1: between species um civilizations. Um. I mean you could make

292
00:14:49,600 --> 00:14:52,240
Speaker 1: the argument that you need to appoint somebody like you

293
00:14:52,280 --> 00:14:55,280
Speaker 1: know what if Dennis Rodman was the was the go

294
00:14:55,360 --> 00:14:58,240
Speaker 1: to man. You know, he's doing so well, Dennis Rodman, Well, yeah,

295
00:14:58,280 --> 00:14:59,960
Speaker 1: I mean he's he's been doing so well in term

296
00:15:00,120 --> 00:15:02,320
Speaker 1: of just being an international emissary, you know, going out

297
00:15:02,400 --> 00:15:06,080
Speaker 1: to North Korea on unofficial behalf of the United States.

298
00:15:06,400 --> 00:15:08,840
Speaker 1: So maybe we send him to other worlds to talk

299
00:15:08,880 --> 00:15:12,280
Speaker 1: to the hideous monster gods. I don't know. All right,

300
00:15:12,320 --> 00:15:13,880
Speaker 1: we're gonna take a quick break and when we come

301
00:15:13,920 --> 00:15:23,640
Speaker 1: back more setting. Well, a lot of this has been

302
00:15:23,840 --> 00:15:26,640
Speaker 1: us looking out at the cosmos, But what about trying

303
00:15:26,680 --> 00:15:30,160
Speaker 1: to take the perspective of an extra terrestrial life form

304
00:15:30,280 --> 00:15:34,240
Speaker 1: looking at us. What would Earth the exo planet look like, yeah,

305
00:15:34,280 --> 00:15:37,360
Speaker 1: because we we're talking about okay, other signal signals that

306
00:15:37,400 --> 00:15:41,120
Speaker 1: we uh, we receive that we may either be listening

307
00:15:41,160 --> 00:15:44,160
Speaker 1: in or being told directly. So it's kind of like

308
00:15:45,160 --> 00:15:46,760
Speaker 1: this in this situation. It makes me think of when

309
00:15:46,760 --> 00:15:49,360
Speaker 1: you're at a restaurant or something, or any public place

310
00:15:49,360 --> 00:15:51,760
Speaker 1: and you're having a conversation with somebody, or maybe you're

311
00:15:51,760 --> 00:15:53,760
Speaker 1: on the phone, and then you realize too late that

312
00:15:53,800 --> 00:15:55,440
Speaker 1: you're an earshot of someone else and you're like, oh,

313
00:15:55,440 --> 00:15:57,440
Speaker 1: my goodness, did they listen to that whole conversation up

314
00:15:57,440 --> 00:15:59,920
Speaker 1: and at this point? And then only then can you

315
00:16:00,080 --> 00:16:02,720
Speaker 1: maybe have a directed comment to them and greet them

316
00:16:02,800 --> 00:16:06,320
Speaker 1: or whatever. So the idea here is that long before

317
00:16:06,360 --> 00:16:09,120
Speaker 1: we even thought about sending a signal, a radio signal

318
00:16:09,160 --> 00:16:13,680
Speaker 1: out into the Great Blafe Beyond, we were inadvertently leaking

319
00:16:13,920 --> 00:16:17,600
Speaker 1: all these radio signals. And it's you know, it wasn't

320
00:16:17,640 --> 00:16:22,240
Speaker 1: the worst stuff that we've necessarily that we've we've contributed,

321
00:16:22,280 --> 00:16:24,640
Speaker 1: but not all of it is exactly something that we

322
00:16:24,680 --> 00:16:29,080
Speaker 1: would put on the galactic resume. Hey, otherwise you're right, Um,

323
00:16:29,120 --> 00:16:32,000
Speaker 1: it's sort of like cleaning up our Facebook page if

324
00:16:32,040 --> 00:16:34,480
Speaker 1: we could write it's like only eighteen year old and

325
00:16:34,480 --> 00:16:37,560
Speaker 1: then you see yourself as a thirty year old exactly. Um.

326
00:16:37,600 --> 00:16:39,800
Speaker 1: So yeah, like you said, we've been kind of leaking

327
00:16:39,840 --> 00:16:44,880
Speaker 1: out this the triatus of humanity since the nineteen thirties

328
00:16:44,920 --> 00:16:48,040
Speaker 1: in the form of AM and FM radio broadcast, TV

329
00:16:48,160 --> 00:16:53,360
Speaker 1: broadcasts and then satellite and radar broadcast. Um. And then

330
00:16:53,440 --> 00:16:56,440
Speaker 1: there's also just the other sort of ambient noise like

331
00:16:56,440 --> 00:16:58,920
Speaker 1: every time you open your garage door. These are all

332
00:16:58,960 --> 00:17:01,280
Speaker 1: signals that are being out there. So we have lots

333
00:17:01,320 --> 00:17:04,760
Speaker 1: of groaning noises, we have lots of uh, I mean

334
00:17:05,080 --> 00:17:07,639
Speaker 1: ultimately a lot of footage of us, of us as

335
00:17:07,680 --> 00:17:10,159
Speaker 1: a biological specimen that I think is going to be

336
00:17:10,280 --> 00:17:14,000
Speaker 1: good regardless. But then you haven't suddssed that the monster costumes.

337
00:17:14,119 --> 00:17:17,080
Speaker 1: You have various levels of fiction and fantasy, you have

338
00:17:17,560 --> 00:17:20,520
Speaker 1: actual depictions of humanity, and it's that it's worth of

339
00:17:20,600 --> 00:17:24,879
Speaker 1: us waging war on each other, um, waging genocide and

340
00:17:25,040 --> 00:17:27,439
Speaker 1: mas just some really horrible images for another culture to

341
00:17:27,440 --> 00:17:28,919
Speaker 1: look at and go, oh, I don't know if we

342
00:17:29,320 --> 00:17:31,600
Speaker 1: need these guys in our in our friend group. Yeah.

343
00:17:31,600 --> 00:17:33,920
Speaker 1: And what's interesting about that is, say it's say that

344
00:17:33,960 --> 00:17:36,160
Speaker 1: you pick up on our frequency, and then it's sort

345
00:17:36,160 --> 00:17:38,880
Speaker 1: of like this ocean of sound coming at us, and

346
00:17:38,880 --> 00:17:41,840
Speaker 1: and the first thing that you hear that is from

347
00:17:41,880 --> 00:17:43,879
Speaker 1: the nineteen thirties, and then you can move onto the

348
00:17:43,920 --> 00:17:46,439
Speaker 1: nineteen fifties and it's like bits and pieces from the

349
00:17:46,480 --> 00:17:49,639
Speaker 1: honeymoon or that's the name of the show, right, Yeah, Honeymooners.

350
00:17:49,800 --> 00:17:54,320
Speaker 1: I Love Lucy. Yeah, trying to make sense of all this, Yeah, yeah,

351
00:17:54,320 --> 00:17:55,840
Speaker 1: I found that really interesting. To the edge of this

352
00:17:56,000 --> 00:17:59,800
Speaker 1: radio bubble, that is that is admitted by our planet

353
00:17:59,840 --> 00:18:04,399
Speaker 1: and by our culture, uh, is about seventy lot years away,

354
00:18:04,800 --> 00:18:07,480
Speaker 1: you know, just spreading out like like ripples in a pond,

355
00:18:07,920 --> 00:18:10,720
Speaker 1: and and near that edge, that's where you find stuff

356
00:18:10,760 --> 00:18:13,080
Speaker 1: like I Love Lucy and the Honeymooners, and I looked

357
00:18:13,080 --> 00:18:14,760
Speaker 1: it up. I was like, oh, I wonder if I

358
00:18:14,920 --> 00:18:18,919
Speaker 1: never really watched those shows. I wonder if interplanetary relations

359
00:18:18,920 --> 00:18:21,679
Speaker 1: were ever covered, and and of course they were to

360
00:18:21,680 --> 00:18:24,280
Speaker 1: a certain extent. There is an episode of The Honeymooners

361
00:18:24,320 --> 00:18:27,680
Speaker 1: called The Man from Space in which Jackie Gleeson dressed

362
00:18:27,760 --> 00:18:31,080
Speaker 1: up in a like a really bad, uh like robot

363
00:18:31,119 --> 00:18:34,879
Speaker 1: alien costume, and then Ralph comes into the door and

364
00:18:35,000 --> 00:18:37,280
Speaker 1: is scared, like he's terrified. He's like, ah, and then

365
00:18:37,280 --> 00:18:41,200
Speaker 1: he voices some concern over the possibility of of alien invasion.

366
00:18:41,480 --> 00:18:44,080
Speaker 1: So even right there in the Honeymooners, they might clickoff

367
00:18:44,119 --> 00:18:46,480
Speaker 1: and say, whoa, there's some sort of you know, underlying

368
00:18:46,560 --> 00:18:48,720
Speaker 1: fear that we might invade them. Maybe we should we

369
00:18:48,720 --> 00:18:50,879
Speaker 1: should lay low. And then there's and I Love Lucy

370
00:18:50,920 --> 00:18:55,160
Speaker 1: episode called Lucy Is Envious that features two different sets

371
00:18:55,280 --> 00:18:58,400
Speaker 1: of of bad Martian costumes, like Lucy and her friend

372
00:18:58,440 --> 00:19:00,840
Speaker 1: around the roof wearing Martian costume is trying to scare

373
00:19:00,840 --> 00:19:02,560
Speaker 1: people off the roof for some reason, and I think

374
00:19:02,920 --> 00:19:05,080
Speaker 1: paying them to do it, Yeah, I don't know. And

375
00:19:05,119 --> 00:19:07,119
Speaker 1: then then there I think their husbands come in and

376
00:19:07,160 --> 00:19:10,520
Speaker 1: scared them wearing the Martian costumes. It's uh. And so

377
00:19:10,600 --> 00:19:12,560
Speaker 1: this is the thing that's out there on that bubble,

378
00:19:12,800 --> 00:19:15,359
Speaker 1: right yeah. And it's concerning what we think are is

379
00:19:15,440 --> 00:19:19,920
Speaker 1: intelligent extraterrestrial life, which is very interesting. I did find

380
00:19:19,920 --> 00:19:22,360
Speaker 1: it really fascinating that Jackie Gleason was apparently a big

381
00:19:22,440 --> 00:19:25,040
Speaker 1: UFO enthusiast, So I wonder what he would make of

382
00:19:25,040 --> 00:19:27,199
Speaker 1: that to to you know, that is into the idea

383
00:19:27,320 --> 00:19:30,439
Speaker 1: of extraterrestrial life as he was, um, you know that

384
00:19:30,520 --> 00:19:33,280
Speaker 1: he's kind of an emissary of it. It's hard to say, right,

385
00:19:33,320 --> 00:19:35,280
Speaker 1: because then there's the whole thing about how we project

386
00:19:35,600 --> 00:19:38,480
Speaker 1: all sorts of things onto other beings, and we have

387
00:19:38,560 --> 00:19:41,399
Speaker 1: these expectations, and really we don't even really know what

388
00:19:41,440 --> 00:19:44,480
Speaker 1: we're dealing with because, as we had pointed out in

389
00:19:44,600 --> 00:19:48,199
Speaker 1: one of the Slime episodes, intelligence can be many different

390
00:19:48,200 --> 00:19:51,320
Speaker 1: things in many different forms, so it may not be

391
00:19:51,400 --> 00:19:54,480
Speaker 1: what we expect. I wanted to point out to that

392
00:19:55,040 --> 00:19:58,360
Speaker 1: if if some sort of extraterrestrial life we're looking at

393
00:19:58,480 --> 00:20:02,239
Speaker 1: us um they might pick up that we are just

394
00:20:02,359 --> 00:20:05,800
Speaker 1: chemically all over the place. They might look at Earth

395
00:20:06,240 --> 00:20:08,840
Speaker 1: and they might look at the biomarkers that indicate our

396
00:20:08,880 --> 00:20:12,800
Speaker 1: planet is rife with flora and fauna, and they would

397
00:20:12,800 --> 00:20:16,680
Speaker 1: do this through spectroscopy, the analysis of light through a spectrometer,

398
00:20:17,240 --> 00:20:19,960
Speaker 1: which allows us to look at the chemical fingerprint of

399
00:20:20,080 --> 00:20:22,920
Speaker 1: every element in chemical and see how much of it

400
00:20:23,000 --> 00:20:27,480
Speaker 1: is absorbed, emitted, and scattered throughout a particular atmosphere. So

401
00:20:27,880 --> 00:20:31,959
Speaker 1: if intelligent aliens were to set their spectrometer sits on us,

402
00:20:31,960 --> 00:20:35,240
Speaker 1: what would they see. They'd see an unusual amount of methane.

403
00:20:35,240 --> 00:20:38,160
Speaker 1: As we noted, things in parts of the Belgian cows

404
00:20:38,160 --> 00:20:41,359
Speaker 1: and such. Um, they would see sodium from sodium vapor,

405
00:20:41,400 --> 00:20:44,679
Speaker 1: street lights switching on. They would just see all sorts

406
00:20:44,680 --> 00:20:49,520
Speaker 1: of things that they wouldn't necessarily expect, and all sorts

407
00:20:49,520 --> 00:20:53,200
Speaker 1: of industrial pollution as well. Right, Yeah, they would see exactly,

408
00:20:53,200 --> 00:20:55,400
Speaker 1: they would see some some of the what we call

409
00:20:55,440 --> 00:21:00,359
Speaker 1: the anthroposyne era markers that's a man made chemic goals,

410
00:21:01,080 --> 00:21:03,679
Speaker 1: and they would know automatically like there's this this is

411
00:21:03,720 --> 00:21:06,000
Speaker 1: a very loud planet with a lot of different things

412
00:21:06,040 --> 00:21:09,520
Speaker 1: going on, um, and it would be pretty obvious that

413
00:21:09,640 --> 00:21:12,600
Speaker 1: something was afoot. Yeah. In his book Neotographs Test and

414
00:21:12,640 --> 00:21:15,160
Speaker 1: also mentioned some of the you know, possible reasons that

415
00:21:15,480 --> 00:21:18,520
Speaker 1: we haven't been discovered, Like, I mean, the idea that

416
00:21:19,119 --> 00:21:20,880
Speaker 1: we're not necessary. It's easy to get into your mind,

417
00:21:20,880 --> 00:21:23,840
Speaker 1: the idea like a super intelligent species out there and

418
00:21:23,880 --> 00:21:26,480
Speaker 1: they're just all knowing and and they just either they

419
00:21:26,960 --> 00:21:28,400
Speaker 1: you know, they found us and they just don't want

420
00:21:28,400 --> 00:21:32,119
Speaker 1: to do anything about it, or yeah, right, you know,

421
00:21:32,160 --> 00:21:35,640
Speaker 1: but you know, it's a big universe. It is a

422
00:21:35,680 --> 00:21:37,920
Speaker 1: big universe. There's a lot of time and a lot

423
00:21:37,920 --> 00:21:41,040
Speaker 1: of distance involved here, and it's easy to I mean,

424
00:21:41,040 --> 00:21:44,320
Speaker 1: it's like finding a needle in a haystack, And so

425
00:21:44,520 --> 00:21:47,000
Speaker 1: there's their possibilities that the Earth is a little clue

426
00:21:47,040 --> 00:21:49,720
Speaker 1: close to the Sun that even if they were receiving

427
00:21:49,720 --> 00:21:51,960
Speaker 1: this data, it would be confusing and they wouldn't really

428
00:21:52,160 --> 00:21:54,760
Speaker 1: know exactly what they were looking at. And you know,

429
00:21:54,800 --> 00:21:58,680
Speaker 1: you have the wrong extraterrestrial analyzing the data that day

430
00:21:58,680 --> 00:22:00,560
Speaker 1: that maybe you know, maybe he us to get home

431
00:22:00,560 --> 00:22:04,760
Speaker 1: to his wife. So you know, give it the due

432
00:22:04,760 --> 00:22:06,920
Speaker 1: diligence that it's required. Does this point to the limits

433
00:22:06,960 --> 00:22:10,600
Speaker 1: of knowledge too? Because it has had noted that intelligence

434
00:22:10,920 --> 00:22:14,320
Speaker 1: and intelligent life can be something beyond what we know

435
00:22:14,560 --> 00:22:18,440
Speaker 1: or we define as intelligent life. And if there is

436
00:22:18,480 --> 00:22:23,000
Speaker 1: an extraterrestrial um civilization out there that is intelligent, I'm

437
00:22:23,000 --> 00:22:25,480
Speaker 1: putting that in air quotes, maybe there are a completely

438
00:22:25,480 --> 00:22:28,080
Speaker 1: different form that that's different from ours that they wouldn't

439
00:22:28,080 --> 00:22:31,159
Speaker 1: be able to recognize the markers of what our intelligent

440
00:22:31,400 --> 00:22:34,159
Speaker 1: civilization is. Yeah, you know, a lot of our our

441
00:22:34,240 --> 00:22:36,600
Speaker 1: fears of alien invasion and all of this, a lot

442
00:22:36,600 --> 00:22:38,720
Speaker 1: of that is because we're reflecting our our understanding of

443
00:22:38,760 --> 00:22:42,080
Speaker 1: ourselves out there into the void. Uh. And you know,

444
00:22:42,160 --> 00:22:43,480
Speaker 1: like I was saying earlier, a lot of it comes

445
00:22:43,480 --> 00:22:45,639
Speaker 1: down to there's sort of a self centeredness even in

446
00:22:45,680 --> 00:22:48,679
Speaker 1: our attempt to understand what's going on beyond us. We

447
00:22:48,720 --> 00:22:50,560
Speaker 1: want to know how we fit in, how we relate,

448
00:22:50,600 --> 00:22:53,879
Speaker 1: how we stack up, and and so as we're you know,

449
00:22:53,920 --> 00:22:57,639
Speaker 1: we we we imagine a being, We imagine a civilization

450
00:22:57,680 --> 00:22:59,800
Speaker 1: out there that would take at least some of the

451
00:22:59,800 --> 00:23:02,000
Speaker 1: same interest that we have. So you look at it

452
00:23:02,040 --> 00:23:03,320
Speaker 1: at humans, and what if we don't. We want to

453
00:23:03,359 --> 00:23:05,080
Speaker 1: plan our flag on things, we want to put our

454
00:23:05,160 --> 00:23:08,560
Speaker 1: name on things. We want to colonize other worlds in

455
00:23:08,560 --> 00:23:10,560
Speaker 1: the long term because that's the that is what would

456
00:23:10,560 --> 00:23:13,199
Speaker 1: allow the long term survival of the species itself. We

457
00:23:13,280 --> 00:23:16,600
Speaker 1: want to keep what we are and and we ultimately

458
00:23:16,680 --> 00:23:20,000
Speaker 1: were terrified of change. We want to, uh, we want

459
00:23:20,040 --> 00:23:22,560
Speaker 1: to in many cases, we want to ravage other places

460
00:23:22,560 --> 00:23:25,360
Speaker 1: for their resources. We want to continue to grow into

461
00:23:25,480 --> 00:23:28,919
Speaker 1: and to fuel ourselves. So we we look to the

462
00:23:28,960 --> 00:23:31,800
Speaker 1: possibility of other civilizations and we kind of expect shades

463
00:23:31,840 --> 00:23:34,520
Speaker 1: of this as well. But you know, but what if

464
00:23:34,560 --> 00:23:37,000
Speaker 1: the the extratrustrial life is more of a you know,

465
00:23:37,240 --> 00:23:40,359
Speaker 1: a passive species and more passive culture. What if they

466
00:23:40,359 --> 00:23:42,879
Speaker 1: aren't interested in interfering or reaching out to us? What

467
00:23:42,920 --> 00:23:45,120
Speaker 1: if they just want to check us off on the list, like, oh,

468
00:23:45,119 --> 00:23:47,600
Speaker 1: there's life here, we'll let just write it down, tell

469
00:23:47,640 --> 00:23:48,760
Speaker 1: us what it is, and we'll us put it to

470
00:23:48,760 --> 00:23:51,879
Speaker 1: the books. Maybe that's all they want. Indeed, maybe it is.

471
00:23:52,760 --> 00:23:55,760
Speaker 1: And you know, in the meantime, we'll continue to be listening,

472
00:23:55,840 --> 00:23:59,560
Speaker 1: right or rather study well, and uh, there's not a

473
00:23:59,640 --> 00:24:03,080
Speaker 1: huge future right now for study. There there was a

474
00:24:03,160 --> 00:24:06,600
Speaker 1: dedicated um telescope array that was planned, called the Allen

475
00:24:06,640 --> 00:24:09,439
Speaker 1: Telescope Array, but the budget cuts have have sort of

476
00:24:09,440 --> 00:24:12,920
Speaker 1: put that into hibernation. But the meantime, said, it continues

477
00:24:13,000 --> 00:24:17,879
Speaker 1: to eavesdrop on the universe, uh, through rented radio telescopes.

478
00:24:18,160 --> 00:24:20,240
Speaker 1: As of now, they still have an artist in residence,

479
00:24:20,480 --> 00:24:25,359
Speaker 1: Charles Lindsay adding these cool structure installation pieces with a

480
00:24:25,440 --> 00:24:27,639
Speaker 1: sound component and all, and it's really cool stuff. But

481
00:24:28,040 --> 00:24:30,119
Speaker 1: that was like a two thousand eleven through two thousand

482
00:24:30,200 --> 00:24:33,080
Speaker 1: thirteen gigs. So I don't do not know if they're

483
00:24:33,080 --> 00:24:35,360
Speaker 1: going to have a second artist in residence. It would

484
00:24:35,359 --> 00:24:37,600
Speaker 1: be awesome if they did, because the whole point of

485
00:24:37,600 --> 00:24:39,560
Speaker 1: that was to try to change our perspective of what

486
00:24:39,640 --> 00:24:42,960
Speaker 1: intelligent life might be, right and in through different forms

487
00:24:42,960 --> 00:24:46,560
Speaker 1: and shapes and I think he captured some really interesting imagery.

488
00:24:46,760 --> 00:24:49,640
Speaker 1: In fact, we'll definitely put that up on Facebook. Yeah yeah,

489
00:24:49,920 --> 00:24:52,240
Speaker 1: and you know, and and steady again. It's it's something

490
00:24:52,280 --> 00:24:56,359
Speaker 1: that even casual observers to space exploration, you know, people

491
00:24:56,400 --> 00:24:59,320
Speaker 1: with a casual interest in science fiction and whatevy. It's

492
00:24:59,359 --> 00:25:03,359
Speaker 1: it's a very real latable uh and and noble goal,

493
00:25:03,600 --> 00:25:05,240
Speaker 1: you know. It's like it's so I think it's a

494
00:25:05,280 --> 00:25:07,800
Speaker 1: great entry point for people to to learn more about

495
00:25:07,840 --> 00:25:12,639
Speaker 1: science and get excited about science and face exploration. All right,

496
00:25:12,680 --> 00:25:14,680
Speaker 1: So there you have it. Um, a little bit about

497
00:25:14,680 --> 00:25:16,720
Speaker 1: the history of Cetti, some of the big points in

498
00:25:16,760 --> 00:25:19,119
Speaker 1: their history, what they're doing and uh, and what the

499
00:25:19,160 --> 00:25:21,000
Speaker 1: future may hold for them and uh. We could sit

500
00:25:21,040 --> 00:25:25,040
Speaker 1: around and ponder and uh and hypothesize and imagine what

501
00:25:25,119 --> 00:25:28,960
Speaker 1: alien life might consist. Tough just all day, but you

502
00:25:28,960 --> 00:25:30,920
Speaker 1: have to keep that confined to certain hours of the

503
00:25:30,960 --> 00:25:33,840
Speaker 1: day so you can get done. So, UM, we would

504
00:25:33,840 --> 00:25:35,679
Speaker 1: love to hear from you, guys if you have anything

505
00:25:35,680 --> 00:25:37,320
Speaker 1: to add on this. What do you think about the

506
00:25:37,320 --> 00:25:39,640
Speaker 1: possibility of life elsewhere in the universe? Do you think

507
00:25:39,640 --> 00:25:42,760
Speaker 1: it exists? Do you know it exists? We love those
