WEBVTT 1 00:00:03.399 --> 00:00:07.719 Welcome to Bedtime Astronomy. Explore the wonders of the cosmos 2 00:00:07.759 --> 00:00:12.279 with our soothing Bedtime Astronomie podcast. Each episode offers a 3 00:00:12.359 --> 00:00:16.320 gentle journey through the stars, planets, and beyond, perfect for 4 00:00:16.399 --> 00:00:20.239 unwinding after a long day. Let's travel through the mysteries 5 00:00:20.239 --> 00:00:22.440 of the universe as you drift off into a peaceful 6 00:00:22.480 --> 00:00:23.800 slumber under the night sky. 7 00:00:27.000 --> 00:00:31.719 So picture the scenario. You're sitting on your couch, right, 8 00:00:32.560 --> 00:00:35.640 It's a random Tuesday, You're half watching TV, just kind 9 00:00:35.679 --> 00:00:38.840 of mindlessly scrolling through your phone's newsfeed, the. 10 00:00:38.840 --> 00:00:40.479 Usual evening routine exactly. 11 00:00:41.039 --> 00:00:44.880 But suddenly your thumb just stops. Your eyes lock onto 12 00:00:44.960 --> 00:00:48.759 this headline in massive bold letters, and it says something 13 00:00:48.840 --> 00:00:52.640 like strongest hints yet of alien life discovered. 14 00:00:52.840 --> 00:00:54.079 Oh wow, all right. 15 00:00:54.159 --> 00:00:56.479 Your heart skips a beat. I mean, you're thinking, this 16 00:00:56.560 --> 00:00:59.280 is it the big one, the ultimate question we've been 17 00:00:59.320 --> 00:01:01.719 asking since we first looked up at the stars, and 18 00:01:01.759 --> 00:01:04.319 it's finally answered while you're just sitting in your living room. 19 00:01:04.400 --> 00:01:06.200 It's a wild feeling, it really is. 20 00:01:06.599 --> 00:01:10.599 But then almost immediately that skeptical, highly trained part of 21 00:01:10.640 --> 00:01:12.560 your brain kicks in. You start wondering, like, do you 22 00:01:12.640 --> 00:01:14.000 actually believe it, right, You. 23 00:01:13.959 --> 00:01:15.959 Have to ask yourself, what's really behind that headline? 24 00:01:16.040 --> 00:01:19.239 Yeah, exactly. How do you even begin to know what 25 00:01:19.319 --> 00:01:22.120 the scientific community as a whole truly thinks about a 26 00:01:22.200 --> 00:01:26.840 claim like that versus you know what one single highly 27 00:01:27.000 --> 00:01:30.480 enthusiastic expert quoted in the second paragraph happens to believe. 28 00:01:30.599 --> 00:01:31.840 It's such an important distinction. 29 00:01:32.159 --> 00:01:36.280 Okay, let's unpack this. Our mission today is to decode 30 00:01:36.560 --> 00:01:40.120 what that phrase science says actually means when we're talking 31 00:01:40.120 --> 00:01:43.920 about these massive paradigm shifting discoveries. We want to move 32 00:01:43.959 --> 00:01:46.959 beyond those binary yes or no headlines and actually see 33 00:01:46.959 --> 00:01:49.560 the hidden mechanics of scientific consensus. 34 00:01:49.799 --> 00:01:52.439 It really is the ultimate modern dilemma, isn't it. Yeah. 35 00:01:52.439 --> 00:01:56.200 I mean we are completely surrounded by information all the time, oh, 36 00:01:56.280 --> 00:01:59.519 drowning in it. Yeah, but we're often completely starved at 37 00:01:59.560 --> 00:02:02.719 the actual context. When a headline drops about something as 38 00:02:02.760 --> 00:02:07.400 monumental as extraterrestrial life, we naturally just crave a binary answer. 39 00:02:07.799 --> 00:02:09.280 Is it aliens or isn't it? 40 00:02:09.360 --> 00:02:11.599 We want the simple truth exactly, But. 41 00:02:11.599 --> 00:02:14.759 The reality of how scientists actually process, debate, and eventually 42 00:02:14.800 --> 00:02:17.919 accept new data is well, it's anything but binary. It's 43 00:02:17.919 --> 00:02:21.840 a highly structured, deeply conscious process that the public rarely 44 00:02:21.879 --> 00:02:22.599 gets to witness. 45 00:02:22.680 --> 00:02:25.039 So let's pull back the curtain on that process, because 46 00:02:25.159 --> 00:02:28.120 you know, we aren't just talking about some hypothetical scenario here. 47 00:02:28.159 --> 00:02:30.680 We are talking about the reality of what actually happened 48 00:02:30.719 --> 00:02:32.000 in the year twenty twenty five. 49 00:02:32.159 --> 00:02:36.199 Ah. Yes, twenty twenty five was quite the year for astrobiology. 50 00:02:36.319 --> 00:02:41.039 It was insane. We had these two absolutely massive blockbuster 51 00:02:41.080 --> 00:02:44.360 announcements that essentially broke the Internet. They commanded the global 52 00:02:44.360 --> 00:02:48.080 news cycle for weeks. The excitement was just palpable. 53 00:02:48.240 --> 00:02:52.680 The expectations were set astronomically high, literally and figuratively right. 54 00:02:52.759 --> 00:02:54.919 So we need to establish exactly what the public was 55 00:02:54.919 --> 00:02:58.159 reacting to. Let's start with April twenty twenty five. We 56 00:02:58.240 --> 00:03:01.400 get this massive news drop arding an exoplanet called K 57 00:03:01.439 --> 00:03:03.919 two eighteen B. For those who might just remember the 58 00:03:03.960 --> 00:03:07.360 chaotic headlines, what was the actual discovery there? Like, mechanically, 59 00:03:07.439 --> 00:03:08.919 what had everyone losing their minds? 60 00:03:09.319 --> 00:03:11.280 Well, the excitement around K two eighteen B was really 61 00:03:11.400 --> 00:03:14.639 rooted in atmosphereic spectroscopy. Okay, So K two eighteen B 62 00:03:14.759 --> 00:03:16.840 is an exoplanet located about one hundred and twenty light 63 00:03:16.879 --> 00:03:19.919 years away. It orbits a red dwarf star, and it 64 00:03:19.960 --> 00:03:23.039 falls into a category scientist call a heisin world. 65 00:03:22.960 --> 00:03:24.960 High scene, meaning like water. 66 00:03:25.240 --> 00:03:27.319 Yeah, exactly, it's a theoretical type of planet with a 67 00:03:27.360 --> 00:03:30.759 hydrogen rich atmosphere and a surface entirely covered by a 68 00:03:30.759 --> 00:03:31.759 liquid water ocean. 69 00:03:32.039 --> 00:03:34.319 Oh wow, an entire ocean. 70 00:03:33.960 --> 00:03:37.000 Planet right now. The way we study a planet like 71 00:03:37.039 --> 00:03:40.240 that is through the transit method. When the planet passes 72 00:03:40.240 --> 00:03:43.520 in front of its host star, this microscopic fraction of 73 00:03:43.560 --> 00:03:47.039 the star's light filters through the planet's atmosphere. 74 00:03:46.439 --> 00:03:48.800 Before traveling one hundred and twenty light years to hit 75 00:03:48.840 --> 00:03:50.759 the James Web Space telescope. 76 00:03:50.400 --> 00:03:54.840 Exactly, and different chemical molecules absorbed specific wavelengths of that 77 00:03:54.960 --> 00:03:57.680 infra red light. So by looking at the gaps in 78 00:03:57.719 --> 00:04:01.000 the light the absorption lines, we can deduce what molecules 79 00:04:01.000 --> 00:04:02.439 are floating in that alien sky. 80 00:04:02.719 --> 00:04:06.840 So it's essentially reading a barcode generated by starlight. 81 00:04:07.159 --> 00:04:09.599 That is actually a highly functional way to think about it. 82 00:04:09.960 --> 00:04:13.199 And so in April twenty twenty five, researchers analyzing the 83 00:04:13.199 --> 00:04:16.839 barcode of K two eighteen B reported finding possible traces 84 00:04:16.879 --> 00:04:18.120 of a specific molecule. 85 00:04:18.240 --> 00:04:19.240 And this was the big one. 86 00:04:19.360 --> 00:04:24.319 Yes, dimethyl sulfide, often abbreviated as DMS. They also noted 87 00:04:24.360 --> 00:04:26.199 potential traces of dimethyl. 88 00:04:25.720 --> 00:04:28.519 Disulfide, which to a casual observer just sounds like you know, 89 00:04:28.680 --> 00:04:29.879 standard industrial chemical. 90 00:04:30.000 --> 00:04:32.879 Yeah, it doesn't sound very glamorous, But to an astrobiologist, 91 00:04:33.079 --> 00:04:37.480 DMS is incredibly provocative because on Earth, dimethyl sulfide is 92 00:04:37.560 --> 00:04:40.439 overwhelmingly associated with biological activity. 93 00:04:40.600 --> 00:04:42.399 Wait really mostly biological. 94 00:04:42.600 --> 00:04:45.120 Yeah, the vast majority of the DMS in our own 95 00:04:45.160 --> 00:04:49.839 atmosphere is produced by marine phytoplankton. You know, microscopic life 96 00:04:49.839 --> 00:04:50.519 in our oceans. 97 00:04:50.639 --> 00:04:51.800 Oh, that's fascinating. 98 00:04:51.959 --> 00:04:55.240 It's actually the sulfur compound that gives the sea its 99 00:04:55.399 --> 00:04:58.120 distinct slightly cabbage e smell. 100 00:04:58.279 --> 00:05:00.560 The ocean smell. So the leap and logic for the 101 00:05:00.560 --> 00:05:02.600 public was just immediably. 102 00:05:02.240 --> 00:05:06.240 Very electrifying. Yes, if a chemical exclusively made by oceanic 103 00:05:06.279 --> 00:05:09.000 life on Earth is found on a distant ocean planet, 104 00:05:09.319 --> 00:05:12.160 then well there must be oceanic life on that planet. 105 00:05:12.240 --> 00:05:14.639 And the media coverage just took that logic and build 106 00:05:14.680 --> 00:05:17.360 a wall of sound. I mean every major outlet was 107 00:05:17.399 --> 00:05:21.240 framing this as an unprecedented advance. The narrative was literally, 108 00:05:21.319 --> 00:05:23.680 we found the ocean smell. Therefore, we found the space whale. 109 00:05:23.759 --> 00:05:24.600 It was everywhere. 110 00:05:24.759 --> 00:05:27.079 But as if that wasn't enough to digest for one year, 111 00:05:27.519 --> 00:05:30.680 September twenty twenty five rules around and we get a 112 00:05:30.759 --> 00:05:35.120 completely different, yet equally mind bending announcement, this time much 113 00:05:35.160 --> 00:05:38.759 closer to home. Yes, Mars, specifically a Martian rock discovered 114 00:05:38.759 --> 00:05:42.240 in the jazerro crater that scientists named Chiava Falls. And 115 00:05:42.279 --> 00:05:44.639 the buzzword that completely took over the Internet for this 116 00:05:44.720 --> 00:05:46.360 one was leopard spots. 117 00:05:46.680 --> 00:05:49.720 The leopard spots, I have to say, it's a brilliantly 118 00:05:49.800 --> 00:05:52.399 evocative piece of scientific branding. 119 00:05:52.279 --> 00:05:54.879 It really is. So what was NASA actually announcing there? 120 00:05:54.920 --> 00:05:58.360 Well, the Perseverance Rover had analyzed the Chiava Falls rock 121 00:05:58.720 --> 00:06:03.279 using its onboard instrument, specifically the PixL instrument, which maps 122 00:06:03.319 --> 00:06:07.800 the chemical composition of rocks at a really tiny submillimeter scale, 123 00:06:07.920 --> 00:06:11.639 and they found what they cautiously termed a potential biosignature. 124 00:06:12.399 --> 00:06:16.519 These leopard spots are essentially tiny millimeter sized mineral rings 125 00:06:16.680 --> 00:06:18.120 found right there within the rock. 126 00:06:18.319 --> 00:06:19.240 And what are they made of? 127 00:06:19.560 --> 00:06:22.959 They consist of a core of iron and phosphate surrounded 128 00:06:22.959 --> 00:06:26.480 by a distinct rim of iron rich minerals. And again, 129 00:06:26.920 --> 00:06:29.160 just like with the exoplanet, we look to our own 130 00:06:29.199 --> 00:06:31.240 planet's geological record for reference. 131 00:06:31.439 --> 00:06:32.879 Right, what does it mean on Earth? 132 00:06:33.040 --> 00:06:37.120 On Earth, rings morphologically identical to these are very frequently 133 00:06:37.160 --> 00:06:38.800 formed by microbial activity. 134 00:06:38.879 --> 00:06:43.680 Oh wow, So actual bacteria, exactly ancient bacteria living in 135 00:06:43.759 --> 00:06:48.920 subsurface water use chemical reduction oxidation reactions redox reactions to 136 00:06:49.040 --> 00:06:51.759 draw energy from the iron in the rock, and the 137 00:06:51.759 --> 00:06:56.199 weights product of that biological metabolism leaves behind these distinct 138 00:06:56.399 --> 00:06:59.759 ring like physical markers. And the rhetoric used at the 139 00:06:59.800 --> 00:07:03.519 absolute highest levels of space exploration was doing nothing to 140 00:07:03.600 --> 00:07:04.959 tamp down the hype on this one. 141 00:07:05.000 --> 00:07:05.759 Oh not at all. 142 00:07:06.040 --> 00:07:09.199 I mean, we had NASA Administrator Sean Duffy stepping up 143 00:07:09.199 --> 00:07:13.120 to the microphone during a globally televised press conference and 144 00:07:13.199 --> 00:07:15.839 he stated on the record that the Chayov of Fall 145 00:07:15.959 --> 00:07:19.360 sample was the closest we have ever come to discovering 146 00:07:19.480 --> 00:07:20.759 life on the Red. 147 00:07:20.519 --> 00:07:22.920 Planet, which is an incredibly strong statement. 148 00:07:23.079 --> 00:07:25.439 Right When the head of NASA says something like that, 149 00:07:25.519 --> 00:07:28.199 you cannot blame the average person for thinking we've basically 150 00:07:28.240 --> 00:07:30.079 found petrified Martian bacteria. 151 00:07:30.240 --> 00:07:33.560 No, it is entirely understandable when leadership at that level 152 00:07:33.800 --> 00:07:36.759 uses language like the closest we have ever come. It 153 00:07:36.759 --> 00:07:38.639 acts as a permission structure. It tells the public to 154 00:07:38.680 --> 00:07:40.120 just let their imaginations run wide. 155 00:07:40.120 --> 00:07:42.439 Oh yeah, gives them the green light, Which raises. 156 00:07:42.199 --> 00:07:46.720 A really fundamental issue regarding how we translate highly technical 157 00:07:46.800 --> 00:07:51.839 data into human storytelling. Why do discoveries like the leopard 158 00:07:51.920 --> 00:07:56.319 spots or the phytoplankton chemical capture the human imagination so violently? 159 00:07:56.399 --> 00:07:58.480 I feel like it's because it's tangible. 160 00:07:58.560 --> 00:08:04.279 Precisely devides a tangible terrestrial anchor abstract absorption lines on 161 00:08:04.319 --> 00:08:08.079 a spectrograph are incredibly difficult for the human brain to 162 00:08:08.160 --> 00:08:09.120 emotionally bond with. 163 00:08:09.319 --> 00:08:11.600 Yeah, nobody's crying over a squiggly line on a. 164 00:08:11.560 --> 00:08:17.199 Graph, exactly. But leverage spots conjures an immediate, visceral image 165 00:08:17.199 --> 00:08:21.519 of biology. It suggests a living, breathing ecosystem, even if 166 00:08:21.519 --> 00:08:25.519 that ecosystem is microbial and billions of years old. The 167 00:08:25.600 --> 00:08:29.120 language bridges the vast cold gap of space with something 168 00:08:29.160 --> 00:08:30.160 warmly familiar. 169 00:08:30.279 --> 00:08:32.639 You know, I look at these scientific announcements as operating 170 00:08:32.759 --> 00:08:34.879 very much like the modern Hollywood movie trailer. 171 00:08:34.919 --> 00:08:36.320 Oh that's an interesting comparison. 172 00:08:36.399 --> 00:08:38.399 Yeah, think about it. When a studio wants you to 173 00:08:38.399 --> 00:08:40.879 go see a complex, two and a half hour sci 174 00:08:40.879 --> 00:08:43.320 fi epic, they don't use the trailer to show you 175 00:08:43.360 --> 00:08:45.279 the fifty minutes of world building exposition. 176 00:08:45.440 --> 00:08:46.480 No, they definitely do not. 177 00:08:46.879 --> 00:08:50.759 They skip the slow character arcs. They take the absolute 178 00:08:50.799 --> 00:08:55.120 most explosive, visually arresting two minutes of footage they have. 179 00:08:55.679 --> 00:08:59.200 They give you the booming bass drop, the dramatic CGI sequence, 180 00:08:59.480 --> 00:09:02.840 and the killer right to get you in the seat exactly. 181 00:09:02.960 --> 00:09:05.480 The entire mechanism is designed to get you into the theater. 182 00:09:05.879 --> 00:09:09.679 But does that two minute trailer accurately reflect the pacing 183 00:09:09.799 --> 00:09:13.000 and the actual reality of sitting through the entire film. 184 00:09:13.080 --> 00:09:13.720 Almost never. 185 00:09:14.000 --> 00:09:14.840 That's very true. 186 00:09:14.960 --> 00:09:17.919 The scientific headlines give us the explosions, they give us 187 00:09:17.960 --> 00:09:21.240 the closest we have ever come quote, but they completely 188 00:09:21.279 --> 00:09:25.720 strip away the actual grueling, methodical process of the scientific method. 189 00:09:25.879 --> 00:09:28.960 The mechanics of your analogy hold up very well under scrutiny. 190 00:09:29.000 --> 00:09:31.840 I think the excitement you feel when watching a trailer 191 00:09:31.919 --> 00:09:35.000 is genuine, just as the excitement of the scientists who 192 00:09:35.039 --> 00:09:38.480 first spoted the DMS signal or the chemical rings is 193 00:09:38.639 --> 00:09:39.519 entirely genuine. 194 00:09:39.559 --> 00:09:40.879 Sure, there's real agena in there. 195 00:09:40.960 --> 00:09:45.440 There really is. However, the public relations machinery surrounding these discoveries, 196 00:09:45.480 --> 00:09:48.120 you know, the university press offices, the media cycles, the 197 00:09:48.159 --> 00:09:51.600 frantic rush for engagement on social media, the whole industry 198 00:09:51.879 --> 00:09:55.559 it is, and it systematically filters out the vital context 199 00:09:55.679 --> 00:09:59.279 that scientists actually live and breathe in a lab setting. 200 00:09:59.559 --> 00:10:02.480 A disc recovery of this magnitude is viewed merely as 201 00:10:02.519 --> 00:10:06.320 the starting pistol for a grueling, decades long process of 202 00:10:06.440 --> 00:10:08.799 verification and brutal peer review. 203 00:10:08.919 --> 00:10:11.000 But in the news media it's presented as crossing the 204 00:10:11.000 --> 00:10:14.080 finish line exactly, and that dynamic brings us to this 205 00:10:14.480 --> 00:10:19.240 massive structural illusion that society is currently living under, which 206 00:10:19.279 --> 00:10:22.720 is the illusion of science says. You see it constantly. Right, 207 00:10:22.799 --> 00:10:25.120 You open an article and the very first sentence is 208 00:10:25.639 --> 00:10:28.399 science says we should do X, or scientists believe they 209 00:10:28.399 --> 00:10:29.159 have found why. 210 00:10:29.240 --> 00:10:30.360 It's everywhere. 211 00:10:30.480 --> 00:10:34.600 It anthropomorphizes the entire scientific endeavor. It treats science as 212 00:10:34.639 --> 00:10:37.919 if it's a monolith, like it's a single omniscient entity 213 00:10:38.240 --> 00:10:40.840 sitting in a room somewhere banging a gavel and making 214 00:10:40.840 --> 00:10:42.720 objective pronouncements from a throne. 215 00:10:42.840 --> 00:10:45.440 What's fascinating here is that the monolithic view of science 216 00:10:45.840 --> 00:10:49.320 is arguably one of the most pervasive and structurally dangerous 217 00:10:49.360 --> 00:10:51.080 misconceptions of our information age. 218 00:10:51.200 --> 00:10:52.120 Dangerous in what way? 219 00:10:52.440 --> 00:10:54.679 Well, we have to look at the economic realities of 220 00:10:54.679 --> 00:10:57.799 how these stories are produced. When a breakthrough like the 221 00:10:57.879 --> 00:11:01.159 K two eighteen B molecules so the MARS hits the wire, 222 00:11:01.759 --> 00:11:06.080 science journalists are operating under extreme, often punishing deadlines. 223 00:11:06.159 --> 00:11:07.480 Right they have to publish immediately. 224 00:11:07.559 --> 00:11:11.919 They have hours, sometimes just minutes to contextualize discoveries that 225 00:11:12.000 --> 00:11:15.480 took decades to make. They need expert quotes to validate 226 00:11:15.519 --> 00:11:17.679 the story, and they need them right now. So what 227 00:11:17.799 --> 00:11:21.399 happens The structural result of that pressure is that journalists 228 00:11:21.480 --> 00:11:25.600 invariably reach out to a small, highly vocal, and easily 229 00:11:25.639 --> 00:11:27.360 accessible subset of experts. 230 00:11:27.639 --> 00:11:30.320 Ah I see. They reach out to the researchers who 231 00:11:30.360 --> 00:11:33.600 have active social media presences, the ones who are dynamic 232 00:11:33.639 --> 00:11:36.679 on camera and who know how to deliver a compelling, 233 00:11:36.879 --> 00:11:38.799 digestible SoundBite precisely. 234 00:11:39.120 --> 00:11:41.679 And we must stress that those individual experts may be 235 00:11:41.879 --> 00:11:45.639 genuinely brilliant. Their views, their optimism, and their interpretations of 236 00:11:45.679 --> 00:11:48.240 the data might be entirely scientifically valid. 237 00:11:48.240 --> 00:11:49.600 We're not saying they're hacks. 238 00:11:49.679 --> 00:11:52.320 Not at all. The danger is not that they are wrong. 239 00:11:53.039 --> 00:11:57.039 The danger is that they rarely represent the complete statistical 240 00:11:57.120 --> 00:12:00.120 distribution of thought within the wider scientific. 241 00:11:59.720 --> 00:12:01.480 Comunity that makes total sense. 242 00:12:01.679 --> 00:12:05.759 The fundamental vulnerability in our public discourse is that systematic 243 00:12:05.960 --> 00:12:10.080 empirical evidence about what the broader community thinks is almost 244 00:12:10.360 --> 00:12:14.720 entirely absent. We are fed the loudest, most accessible voices, 245 00:12:15.080 --> 00:12:18.519 and we mistake them for the collective, integrated voice of 246 00:12:18.559 --> 00:12:19.600 the entire discipline. 247 00:12:19.679 --> 00:12:22.879 Right if a researcher has dedicated their entire forty year 248 00:12:22.960 --> 00:12:27.320 career to the search for extraterrestrial biosignatures and they're finally 249 00:12:27.399 --> 00:12:31.240 handed a microphone, their baseline response is naturally going to 250 00:12:31.279 --> 00:12:32.320 skew optimistic. 251 00:12:32.440 --> 00:12:35.000 They're primed to see the signal in the noise exactly. 252 00:12:35.559 --> 00:12:39.000 But taking that one highly enthusiastic researcher and framing their 253 00:12:39.080 --> 00:12:42.840 quote as scientists believe, completely warps the public's understanding of 254 00:12:42.840 --> 00:12:46.559 a subject that is probably being fiercely debated in the literature. 255 00:12:46.840 --> 00:12:49.639 I want you, the listener, to really reflect on how 256 00:12:49.720 --> 00:12:53.960 often you see the phrase experts say in your daily reading. 257 00:12:55.000 --> 00:12:59.600 We've been conditioned to assume that phrase indicates universal unquestioned 258 00:12:59.639 --> 00:13:03.639 agree among thousands of researchers in lab coats, all nodding 259 00:13:03.679 --> 00:13:05.159 in unison, when. 260 00:13:05.039 --> 00:13:07.759 The reality of the scientific method is the exact opposite 261 00:13:07.759 --> 00:13:10.759 of that right. The irony is that these isolated, optimistic 262 00:13:10.840 --> 00:13:15.879 quotes inadvertently mask the rigorous, incredibly healthy, and often contentious 263 00:13:15.879 --> 00:13:18.480 debate that is the actual lifeblood of science. 264 00:13:18.559 --> 00:13:20.120 The debate is the point exactly. 265 00:13:20.440 --> 00:13:23.720 The scientific method does not thrive on consensus. It thrives 266 00:13:23.759 --> 00:13:28.399 on targeted skepticism. It explicitly demands that any new empirical 267 00:13:28.399 --> 00:13:32.600 claim be systematically torn apart, tested, stressed, and scrutinized from 268 00:13:32.679 --> 00:13:35.480 every conceivable angle before it's provisionally accepted. 269 00:13:35.519 --> 00:13:37.960 But the public is shielded from the tearing apart. They 270 00:13:37.960 --> 00:13:40.919 don't see the brutal pere review comments, or the failed 271 00:13:40.960 --> 00:13:44.159 replication attempts, or the alternative hypotheses. 272 00:13:44.440 --> 00:13:47.000 No, they only see the shiny new claim standing on 273 00:13:47.039 --> 00:13:50.799 a pedestal, structurally supported by a few enthusiastic quotes. 274 00:13:51.240 --> 00:13:55.600 So this presents a massive logistical problem for us the public. 275 00:13:56.080 --> 00:13:58.600 If we know we can't trust the headlines to give 276 00:13:58.679 --> 00:14:03.120 us the actual, unvar furnished consensus, how do we measure it? 277 00:14:03.200 --> 00:14:04.080 Do we just guess. 278 00:14:04.240 --> 00:14:05.600 That's the million dollar question. 279 00:14:05.759 --> 00:14:08.200 Do we wait ten or fifteen years for the dust 280 00:14:08.240 --> 00:14:10.960 to settle and a new textbook to be published that 281 00:14:11.120 --> 00:14:14.399 isn't feasible when policy and billions of dollars in funding 282 00:14:14.399 --> 00:14:15.240 are on the line today. 283 00:14:15.320 --> 00:14:16.759 No, we don't have that kind of time. 284 00:14:16.639 --> 00:14:19.720 Which is where I want to introduce a truly brilliant 285 00:14:19.960 --> 00:14:25.000 systemic intervention into this chaotic information ecosystem, because we don't 286 00:14:25.039 --> 00:14:28.360 have to just guess anymore. In response to this exact problem, 287 00:14:28.440 --> 00:14:31.039 a research group was formed at Durham University known as 288 00:14:31.240 --> 00:14:31.840 se SCOPE. 289 00:14:32.000 --> 00:14:32.240 Yes. 290 00:14:32.679 --> 00:14:35.399 C SCOPE it stands for the Center for Scientific Community 291 00:14:35.399 --> 00:14:38.360 Opinion Polling and Evaluation, and what they were doing is 292 00:14:38.440 --> 00:14:42.919 fundamentally rewiring how we understand scientific breakthroughs in real time. 293 00:14:43.080 --> 00:14:45.559 The architecture of what CESCOPE is doing is a vital 294 00:14:45.600 --> 00:14:49.639 evolution in the sociology of science. Really well. Their methodology 295 00:14:49.720 --> 00:14:54.000 was explicitly designed to solve the exact bandwidth problem we're analyzing. 296 00:14:54.519 --> 00:14:57.120 Instead of waiting for the historical dust to settle or 297 00:14:57.159 --> 00:15:00.639 relying on the flawed proxy of media quotes, they actively 298 00:15:00.639 --> 00:15:03.440 measure the community's response while the debate. 299 00:15:03.159 --> 00:15:05.000 Is actually happening in real time. 300 00:15:05.159 --> 00:15:07.840 Yes, Within mere days of the K two, eighteen B 301 00:15:07.919 --> 00:15:11.000 and Chayava falls announcements in twenty twenty five, the c 302 00:15:11.200 --> 00:15:16.559 scope infrastructure mobilized. They executed a highly structured polling operation 303 00:15:17.039 --> 00:15:20.399 reaching out to hundreds of practicing astrobiologists globally. 304 00:15:20.480 --> 00:15:21.840 Oh hundreds of them. 305 00:15:22.000 --> 00:15:27.279 We are talking about geochemists, planetary atmospheric dynamicists, microbiologists, the 306 00:15:27.360 --> 00:15:30.720 exact people who study these highly specific mechanisms for a 307 00:15:30.759 --> 00:15:34.360 living se scope would directly to the source and ask 308 00:15:34.480 --> 00:15:38.559 them systematically and anonymously to evaluate the strength of the evidence. 309 00:15:38.679 --> 00:15:40.519 Okay, I have to jump in and push back on 310 00:15:40.559 --> 00:15:41.120 this concept. 311 00:15:41.120 --> 00:15:42.000 Please do because I. 312 00:15:41.919 --> 00:15:44.679 Can hear the epistemological alarms going off in the listener's 313 00:15:44.679 --> 00:15:47.879 head right now. Isn't the entire foundation of science supposed 314 00:15:47.879 --> 00:15:52.120 to be empirical facts? It is explicitly not a popularity contest. 315 00:15:52.200 --> 00:15:53.720 That's a very fair point, right. 316 00:15:53.840 --> 00:15:56.799 If gravity exists, we don't need to send a survey 317 00:15:56.840 --> 00:15:59.480 monkey link to a bunch of physicists to make it true. 318 00:16:00.039 --> 00:16:02.120 We don't take a democratic vote on whether the Earth 319 00:16:02.159 --> 00:16:05.840 is round, So why on Earth are we pulling astrobiologists 320 00:16:05.919 --> 00:16:09.879 about Mars rocks. Doesn't the very act of polling scientists 321 00:16:10.159 --> 00:16:14.279 completely undermine the core philosophy that science relies on hard 322 00:16:14.360 --> 00:16:15.279 objective data. 323 00:16:15.679 --> 00:16:19.559 That is a profound philosophical objection, and honestly, it is 324 00:16:19.600 --> 00:16:22.679 the exact correct response when first encountering this concept. 325 00:16:22.720 --> 00:16:24.440 Okay, glad, I'm not crazy. 326 00:16:24.200 --> 00:16:26.919 Not at all. You are entirely correct that the established 327 00:16:26.919 --> 00:16:30.279 physical laws of the universe do not care about democratic majorities. 328 00:16:30.399 --> 00:16:32.919 The mass of an electron is not subject to a 329 00:16:32.919 --> 00:16:37.679 public referendum exactly. But Cescope's underlying operational philosophy relies on 330 00:16:37.720 --> 00:16:41.320 a crucial distinction regarding the timeline of knowledge. They are 331 00:16:41.360 --> 00:16:44.600 explicitly not attempting to replace hard mass spectrometry data with 332 00:16:44.679 --> 00:16:47.919 opinion polls, nor are they treating a majority opinion as 333 00:16:47.919 --> 00:16:50.000 an objective indicator of ultimate truth. 334 00:16:50.519 --> 00:16:51.559 So what are they doing. 335 00:16:51.679 --> 00:16:54.919 What they're doing is mapping the territory between complete ignorance 336 00:16:55.120 --> 00:16:58.480 and established scientific law. They are focusing on the bleeding 337 00:16:58.600 --> 00:17:00.320 edge of emerging evidence. 338 00:17:00.159 --> 00:17:02.879 The bleeding edge where the data is still raw. 339 00:17:03.240 --> 00:17:07.599 Precisely at the bleeding edge, the facts are inherently unsettled. 340 00:17:08.200 --> 00:17:10.559 The data coming back from a telescope or a rover 341 00:17:11.039 --> 00:17:14.440 is often incredibly noisy. It's usually incomplete, and it is 342 00:17:14.519 --> 00:17:19.920 intensely open to the theoretical interpretation. Therefore, pulling the experts 343 00:17:19.920 --> 00:17:22.920 at this stage does not tell us what the ultimate 344 00:17:23.000 --> 00:17:26.960 objective truth of the universe is. Rather, it maps the 345 00:17:26.960 --> 00:17:28.880 internal process of knowledge formation. 346 00:17:29.119 --> 00:17:30.319 Ah I guess. 347 00:17:30.359 --> 00:17:34.240 It utilizes a concept akin to Bayesian updating. It measures 348 00:17:34.240 --> 00:17:36.880 how the community best equipped to understand the raw data 349 00:17:37.319 --> 00:17:40.640 is currently weighing the probabilities based on their prior knowledge 350 00:17:40.680 --> 00:17:43.720 and the new evidence. It is a systematic measurement of 351 00:17:43.759 --> 00:17:46.480 the collective response to profound uncertainty. 352 00:17:46.599 --> 00:17:49.519 Ah I see. So the poll isn't establishing reality. It's 353 00:17:49.559 --> 00:17:52.960 acting as a highly calibrated thermometer. It's taking the temperature 354 00:17:52.960 --> 00:17:55.519 of the room to see how robust the evidence actually 355 00:17:55.599 --> 00:17:57.680 is right now before the textbooks. 356 00:17:57.200 --> 00:17:59.319 Are written exactly. A thermometer is a great way to 357 00:17:59.319 --> 00:17:59.640 put it. 358 00:18:00.000 --> 00:18:02.720 So when you frame it as measuring Baesian probability rather 359 00:18:02.759 --> 00:18:05.960 than voting on reality, it makes total sense. So let's 360 00:18:05.960 --> 00:18:08.839 look at the readout on that thermometer. What were the 361 00:18:08.920 --> 00:18:12.720 actual numbers unveiled by the Seascope project for these two 362 00:18:13.240 --> 00:18:15.200 massive twenty twenty five announcements. 363 00:18:15.519 --> 00:18:18.039 The results were quite illuminating. 364 00:18:17.480 --> 00:18:19.960 Because the contrast between the media hype we explored in 365 00:18:20.000 --> 00:18:24.200 section one, and the actual measured astrobiology polls is severe 366 00:18:24.319 --> 00:18:27.480 enough to give you whiplash. Let's start with the exoplanet 367 00:18:27.599 --> 00:18:30.480 K two eighteen B. The media narrative was that this 368 00:18:30.599 --> 00:18:33.960 was the strongest hint yet of alien life. What did 369 00:18:34.000 --> 00:18:38.640 the actual practicing astrobiologists say? When granted anonymity. 370 00:18:38.279 --> 00:18:41.359 The reality check provided by the data was staggering. When 371 00:18:41.400 --> 00:18:44.400 the seescope researchers asked the global astrobiology community if they 372 00:18:44.400 --> 00:18:47.359 agreed with the premise at scientists had probably found extraterrestrial 373 00:18:47.400 --> 00:18:50.319 life on K two eighteen B, only six point six 374 00:18:50.359 --> 00:18:51.240 percent of them agreed. 375 00:18:51.319 --> 00:18:53.000 Wait what six point six percent? 376 00:18:53.160 --> 00:18:55.799 Yes, we must pause on that figure. Only six point 377 00:18:55.880 --> 00:18:58.279 six percent of the surveyed experts bought into the core 378 00:18:58.319 --> 00:19:00.000 premise that dominated the global news. 379 00:19:00.319 --> 00:19:01.200 That's incredibly low. 380 00:19:01.359 --> 00:19:03.920 Moving further down the scale, nearly two thirds of the 381 00:19:03.960 --> 00:19:07.799 respondent's outright disagreed with the claim that life had been found, 382 00:19:08.240 --> 00:19:12.400 and a highly significant portion exactly twenty eight point zero 383 00:19:12.519 --> 00:19:16.640 percent selected a completely neutral stance, refusing to commit to 384 00:19:16.680 --> 00:19:17.359 either side. 385 00:19:17.559 --> 00:19:21.000 Six point six percent. That is an absolute demolition of 386 00:19:21.039 --> 00:19:23.680 the public narrative. If you were just a casual consumer 387 00:19:23.759 --> 00:19:26.160 reading the news that week. Judging by the tone and 388 00:19:26.200 --> 00:19:28.480 the volume of the coverage, you would have reasonably assumed 389 00:19:28.519 --> 00:19:31.640 that agreement number was hovering around ninety or ninety nine percent. 390 00:19:31.759 --> 00:19:33.680 Absolutely, the disconnect is massive. 391 00:19:33.880 --> 00:19:37.720 Now, what about the Mars rock Cheiava Falls. This was 392 00:19:37.759 --> 00:19:40.599 the one where Administrator Duffy explicitly said it was the 393 00:19:40.680 --> 00:19:43.279 closest we've ever come? Did the scientists agree with the 394 00:19:43.319 --> 00:19:44.039 head of NASA? 395 00:19:44.079 --> 00:19:47.319 The baseline confidence was certainly higher for the Mars discovery 396 00:19:47.319 --> 00:19:50.559 compared to the exo planet, but it remained heavily structurally 397 00:19:50.599 --> 00:19:54.279 cautious for Chaba Falls. Fifteen point one percent of the 398 00:19:54.279 --> 00:19:57.519 polled astrobiologists agreed that life had probably been found. 399 00:19:57.599 --> 00:19:59.519 Okay, so higher, but still pretty low. 400 00:19:59.720 --> 00:20:03.319 Right. The outright disagreement category fell from the two thirds 401 00:20:03.319 --> 00:20:05.920
