1 00:00:08,400 --> 00:00:12,040 Speaker 1: When I say the phrase aliens have arrived, what comes 2 00:00:12,039 --> 00:00:15,160 Speaker 1: to your mind? Do you think about humans getting sliced 3 00:00:15,200 --> 00:00:18,280 Speaker 1: to pieces and served for dinner, or alien ships blasting 4 00:00:18,280 --> 00:00:21,720 Speaker 1: our cities from space. Well, here in our happy corner 5 00:00:21,760 --> 00:00:24,920 Speaker 1: of the podcast Universe, we like to be optimistic. There 6 00:00:24,960 --> 00:00:28,240 Speaker 1: are potentially huge upsides to an alien arrival for the 7 00:00:28,400 --> 00:00:31,040 Speaker 1: curious among us, and among those I count not just 8 00:00:31,200 --> 00:00:33,760 Speaker 1: the host of this podcast, of course, but you, the 9 00:00:33,840 --> 00:00:37,120 Speaker 1: listeners in our community of wonderers. For those of us 10 00:00:37,159 --> 00:00:40,080 Speaker 1: who are curious about the universe, meeting aliens who are 11 00:00:40,120 --> 00:00:43,280 Speaker 1: technologically advanced enough to arrive on Earth seems like a 12 00:00:43,400 --> 00:01:02,320 Speaker 1: great opportunity. Pie. I'm Daniel, I'm a particle physicist and 13 00:01:02,360 --> 00:01:05,560 Speaker 1: a professor at UC Irvine, and I want to know 14 00:01:05,720 --> 00:01:09,080 Speaker 1: the secrets that aliens have learned about the universe. And 15 00:01:09,120 --> 00:01:12,600 Speaker 1: Welcome to the podcast Daniel and Jorge Explain the Universe, 16 00:01:12,640 --> 00:01:15,440 Speaker 1: a production of I Heart Radio. My co host Jorge 17 00:01:15,600 --> 00:01:17,840 Speaker 1: Champ can't be with us today, so it's just me 18 00:01:17,920 --> 00:01:21,319 Speaker 1: and a guest to talk about the secrets of aliens science. 19 00:01:21,840 --> 00:01:26,160 Speaker 1: Imagine for a moment the best case scenario, aliens arrive 20 00:01:26,280 --> 00:01:29,319 Speaker 1: on Earth and they are friendly, and we can figure 21 00:01:29,360 --> 00:01:31,880 Speaker 1: out how to talk to them, and our scientists can 22 00:01:31,920 --> 00:01:36,040 Speaker 1: talk to their scientists. Maybe these aliens know things about 23 00:01:36,200 --> 00:01:39,559 Speaker 1: space and time or quantum mechanics that we haven't figured 24 00:01:39,600 --> 00:01:42,679 Speaker 1: out yet. Maybe we could fast forward human science a 25 00:01:42,720 --> 00:01:46,640 Speaker 1: thousand years or a million years. In this picture, you 26 00:01:46,680 --> 00:01:50,160 Speaker 1: can imagine human and alien scientists are like together, engaged 27 00:01:50,240 --> 00:01:53,600 Speaker 1: in some grand project to unravel the secrets of the universe. 28 00:01:54,280 --> 00:01:56,560 Speaker 1: If we can talk to them, and if they do 29 00:01:56,640 --> 00:01:59,279 Speaker 1: science like we do, and if we can make sense 30 00:01:59,320 --> 00:02:02,480 Speaker 1: of what they've learned, it could be an incredible moment, 31 00:02:02,760 --> 00:02:05,760 Speaker 1: really a pivot in human history. But is that possible? 32 00:02:05,920 --> 00:02:08,640 Speaker 1: As one listener asked a few weeks ago, could we 33 00:02:08,720 --> 00:02:12,919 Speaker 1: even rocket or would they be too advanced? So today 34 00:02:12,919 --> 00:02:20,840 Speaker 1: on the podcast, we'll be asking the question, could aliens 35 00:02:21,040 --> 00:02:25,120 Speaker 1: teach us science? Could we establish a common enough understanding 36 00:02:25,160 --> 00:02:29,640 Speaker 1: to communicating about complex intellectual questions like particle physics? Would 37 00:02:29,639 --> 00:02:32,560 Speaker 1: they be interested in the same questions we are, Would 38 00:02:32,560 --> 00:02:35,160 Speaker 1: we be able to understand their science? Could it be 39 00:02:35,200 --> 00:02:38,640 Speaker 1: incompatible with ours? Are we certain they would even have 40 00:02:38,760 --> 00:02:42,240 Speaker 1: developed science in order to be technological To help me 41 00:02:42,280 --> 00:02:45,600 Speaker 1: explore these questions, it's my pleasure to introduce today's guest 42 00:02:45,760 --> 00:02:49,080 Speaker 1: Samuel Kimpton I. Samuel is a research associate at the 43 00:02:49,160 --> 00:02:51,799 Speaker 1: University of Bristol. He works on issues at the intersection 44 00:02:51,840 --> 00:02:54,880 Speaker 1: of metaphysics and the philosophy of science. Currently, he's working 45 00:02:54,919 --> 00:02:57,680 Speaker 1: on the Meta Science Project, which seeks to unify the 46 00:02:57,760 --> 00:02:59,880 Speaker 1: natural sciences, but he agreed to join me on the 47 00:03:00,000 --> 00:03:03,120 Speaker 1: podcast to talk about aliens and how they think about science. 48 00:03:03,200 --> 00:03:05,919 Speaker 1: Sam Welcome to the podcast. Thanks so much for having me, Daniel, 49 00:03:06,080 --> 00:03:08,840 Speaker 1: So tell me first, how often does the topic of 50 00:03:08,880 --> 00:03:12,360 Speaker 1: aliens and their scientific minds come up in metaphysics and 51 00:03:12,400 --> 00:03:15,440 Speaker 1: philosophy of science. Is it totally fringe or is there 52 00:03:15,480 --> 00:03:19,160 Speaker 1: like a whole journal devoted to this topic. Good question. 53 00:03:19,440 --> 00:03:21,560 Speaker 1: Far from a whole journal, now that that would be 54 00:03:21,639 --> 00:03:26,280 Speaker 1: a stretch. I mean, philosophers are very interested in thinking 55 00:03:26,320 --> 00:03:30,840 Speaker 1: about wacky, far out possibilities and scenarios, so aliens do 56 00:03:31,000 --> 00:03:34,600 Speaker 1: come up occasionally. There are also other monsters in there, 57 00:03:34,639 --> 00:03:38,480 Speaker 1: sometimes zombies, vampires and the like. So I wasn't completely 58 00:03:38,480 --> 00:03:40,680 Speaker 1: surprised that you choose to ask a philosopher to talk 59 00:03:40,720 --> 00:03:42,840 Speaker 1: about this sort of thing. It seems to me exactly 60 00:03:42,840 --> 00:03:45,000 Speaker 1: the kind of things philosophers might love to talk about 61 00:03:45,400 --> 00:03:48,680 Speaker 1: because it's a great way to ask one specific question, 62 00:03:48,960 --> 00:03:52,560 Speaker 1: you know, asking the question, how do aliens think about science? 63 00:03:52,560 --> 00:03:55,440 Speaker 1: Could we understand their science? Seems to me a great 64 00:03:55,480 --> 00:03:59,360 Speaker 1: way to reflect on whether or not our science is 65 00:03:59,520 --> 00:04:02,520 Speaker 1: universe all or just human, you know, whether it's something 66 00:04:02,560 --> 00:04:05,480 Speaker 1: we've discovered or something we've invented. So I would be 67 00:04:05,480 --> 00:04:09,320 Speaker 1: a little surprised if it's not something philosophers already thinking about. Yeah, 68 00:04:09,360 --> 00:04:11,920 Speaker 1: that's right. I mean, it's something that I've been thinking 69 00:04:11,960 --> 00:04:15,440 Speaker 1: about recently actually in the context of the philosophy of 70 00:04:15,440 --> 00:04:18,080 Speaker 1: the laws of nature and to what extent we should 71 00:04:18,120 --> 00:04:21,040 Speaker 1: be kind of realist or pragmatists about these things. And 72 00:04:21,080 --> 00:04:22,760 Speaker 1: maybe we can get into that in some more detail. 73 00:04:22,839 --> 00:04:25,839 Speaker 1: But there's definitely some value, certainly in thinking about how 74 00:04:26,320 --> 00:04:29,120 Speaker 1: just beings with very different kind of modes of cognition 75 00:04:29,600 --> 00:04:32,760 Speaker 1: might explore the world and kind of systematize their experiences 76 00:04:32,760 --> 00:04:35,760 Speaker 1: as well. Right, So, you know, we've got our five senses, 77 00:04:35,839 --> 00:04:38,640 Speaker 1: and that seems to be completely integralt up to how 78 00:04:38,640 --> 00:04:40,280 Speaker 1: we're going to explore the world, and so we're going 79 00:04:40,320 --> 00:04:42,400 Speaker 1: to be systematizing the world on the basis of our 80 00:04:42,600 --> 00:04:46,480 Speaker 1: sense experience. But it seems certainly imaginable that some other 81 00:04:46,520 --> 00:04:48,800 Speaker 1: creatures would have very different senses, and so the way 82 00:04:48,839 --> 00:04:51,600 Speaker 1: they systematize the world and do science would be would 83 00:04:51,600 --> 00:04:54,760 Speaker 1: be quite different. Indeed, in senses are something that philosophers 84 00:04:54,760 --> 00:04:56,760 Speaker 1: I know, to talk about a lot. Is a person 85 00:04:56,880 --> 00:04:58,800 Speaker 1: isolated in a room who has never seen the color 86 00:04:58,880 --> 00:05:01,960 Speaker 1: red and notion of quality. But it seems to me 87 00:05:02,040 --> 00:05:04,839 Speaker 1: to be sort of a difficult topic to explore because 88 00:05:04,880 --> 00:05:08,920 Speaker 1: we are limited to our senses, and so we're sort 89 00:05:08,920 --> 00:05:10,800 Speaker 1: of in a box, and it's hard to imagine, like 90 00:05:10,880 --> 00:05:12,760 Speaker 1: what it's like to be in a different box where 91 00:05:12,760 --> 00:05:16,120 Speaker 1: you experience the universe with totally different senses. It's the 92 00:05:16,120 --> 00:05:18,159 Speaker 1: goal there to think about, like what it would be 93 00:05:18,240 --> 00:05:22,839 Speaker 1: like to experience the universe if you could like taste electrons, 94 00:05:22,960 --> 00:05:25,920 Speaker 1: or if you had some sense for dark matter or neutrinos. 95 00:05:26,320 --> 00:05:28,360 Speaker 1: Is it possible for us to really take that jump 96 00:05:28,360 --> 00:05:31,200 Speaker 1: into sort of logic our way into what it's like 97 00:05:31,320 --> 00:05:32,640 Speaker 1: to be a bat and you know, what it's like 98 00:05:32,680 --> 00:05:35,520 Speaker 1: to be an alien? Or is that really impossible? Exactly right? 99 00:05:35,560 --> 00:05:37,720 Speaker 1: I think that's the exact sort sorts of issues that 100 00:05:37,800 --> 00:05:40,599 Speaker 1: people might like to wrestle within this area, right, And yeah, 101 00:05:40,640 --> 00:05:42,480 Speaker 1: you've got the reference in there to what it's like 102 00:05:42,640 --> 00:05:46,000 Speaker 1: to be a bat, and famously, philosopher Thomas Nagil argued 103 00:05:46,040 --> 00:05:47,880 Speaker 1: that we can't possibly know what it's like to be 104 00:05:47,920 --> 00:05:50,240 Speaker 1: about but while that might be the case, at least 105 00:05:50,279 --> 00:05:52,839 Speaker 1: we can sort of start to think about why that's so. Right, 106 00:05:52,880 --> 00:05:56,039 Speaker 1: So the bat navigates by by sonar as opposed to 107 00:05:56,080 --> 00:05:59,039 Speaker 1: kind of visual experiences, and while we can kind of 108 00:05:59,279 --> 00:06:02,760 Speaker 1: do some side of sonar, it seems a long step 109 00:06:02,839 --> 00:06:05,680 Speaker 1: from that to actually being able to know what it's 110 00:06:05,720 --> 00:06:08,599 Speaker 1: like to be that bat. And so it certainly seems 111 00:06:08,760 --> 00:06:12,400 Speaker 1: imaginable that there are just other actual creatures out there, 112 00:06:12,520 --> 00:06:15,440 Speaker 1: or possible alien creatures that would just experienced the world 113 00:06:15,480 --> 00:06:18,800 Speaker 1: so dramatically differently to us that it would be impossible 114 00:06:18,880 --> 00:06:21,520 Speaker 1: to kind of get into their perspectives and their minds. 115 00:06:21,600 --> 00:06:23,719 Speaker 1: And so this is quite mind boggling to think that 116 00:06:23,760 --> 00:06:27,440 Speaker 1: the way that we're experiencing the universe is potentially quite 117 00:06:27,640 --> 00:06:29,760 Speaker 1: limited in a way. And we know that it's limited. 118 00:06:29,760 --> 00:06:32,200 Speaker 1: I mean, physics at least has told us that most 119 00:06:32,240 --> 00:06:34,880 Speaker 1: of the universe is invisible to us. You know, most 120 00:06:34,880 --> 00:06:37,000 Speaker 1: of the universe is dark matter, which we don't even 121 00:06:37,000 --> 00:06:39,279 Speaker 1: know what it is, and even of the matter that 122 00:06:39,320 --> 00:06:42,280 Speaker 1: we are familiar with, like neutrinos are streaming in front 123 00:06:42,279 --> 00:06:44,680 Speaker 1: of us all of the time, but we can't see them, 124 00:06:44,720 --> 00:06:46,839 Speaker 1: And so there's a lot. We know for a fact 125 00:06:46,920 --> 00:06:48,680 Speaker 1: that there's a lot going on in the universe that 126 00:06:48,760 --> 00:06:52,080 Speaker 1: we do not sense, and that therefore our mental picture 127 00:06:52,080 --> 00:06:54,599 Speaker 1: of the universe is a very particular one. And it 128 00:06:54,600 --> 00:06:57,320 Speaker 1: seems frustrating but enticing to me at the same time. Like, 129 00:06:57,600 --> 00:07:00,880 Speaker 1: if aliens are so alien that they might be impossible 130 00:07:00,920 --> 00:07:04,680 Speaker 1: for us to really digest, that also suggest that they 131 00:07:04,680 --> 00:07:08,039 Speaker 1: have some very valuable insight, Like the more alien they are, 132 00:07:08,480 --> 00:07:11,240 Speaker 1: the more valuable it is to try to understand their minds. 133 00:07:11,360 --> 00:07:15,960 Speaker 1: But then periodoxically, the more impossible it might be. Yeah, interesting, right, So, 134 00:07:16,080 --> 00:07:18,360 Speaker 1: like you said, it's tantalizing because even if we were 135 00:07:18,360 --> 00:07:20,640 Speaker 1: to encounter these creatures, maybe we just have no way 136 00:07:20,680 --> 00:07:23,760 Speaker 1: of communicating with them, so we have no into their insights. 137 00:07:24,040 --> 00:07:25,600 Speaker 1: But then I guess there there might be kind of 138 00:07:25,760 --> 00:07:28,240 Speaker 1: two dimensions to this issue. So what you said, they're 139 00:07:28,240 --> 00:07:31,640 Speaker 1: suggested the possibility of creatures that might be able to 140 00:07:31,760 --> 00:07:34,160 Speaker 1: perceive things that maybe we have some sort of knowledge 141 00:07:34,160 --> 00:07:36,800 Speaker 1: of but no direct perception of, things like neutrinos and that. 142 00:07:37,160 --> 00:07:39,480 Speaker 1: But I suppose another thing that we might think is 143 00:07:39,520 --> 00:07:41,880 Speaker 1: just that, going back to the bad example, they kind 144 00:07:41,880 --> 00:07:44,640 Speaker 1: of the mode of perceiving one's environment might just be 145 00:07:44,760 --> 00:07:47,160 Speaker 1: very different for the aliens. So if they perceived by 146 00:07:47,600 --> 00:07:50,440 Speaker 1: reflecting sound waves of surfaces, that would just give them 147 00:07:50,440 --> 00:07:53,400 Speaker 1: a very different kind of experience. I also often think 148 00:07:53,440 --> 00:07:56,160 Speaker 1: about the example of the aliens in that the Ted 149 00:07:56,240 --> 00:07:59,080 Speaker 1: Chang story Stories of Your Life or the film Rival, 150 00:07:59,400 --> 00:08:01,520 Speaker 1: and they have this very differently if I remember correctly 151 00:08:01,520 --> 00:08:03,080 Speaker 1: as well, I guess, and so since I read the 152 00:08:03,120 --> 00:08:07,400 Speaker 1: short story, but they have this very different perception of time, right, 153 00:08:07,440 --> 00:08:09,640 Speaker 1: And it seems plausible to me that there could be 154 00:08:09,680 --> 00:08:12,240 Speaker 1: a creature with a very different perception of time, and 155 00:08:12,280 --> 00:08:14,560 Speaker 1: then that would just make the way they systematized and 156 00:08:14,600 --> 00:08:17,600 Speaker 1: think about their worlds so different from us. Absolutely. I 157 00:08:17,600 --> 00:08:19,440 Speaker 1: think one of the really fun things about that story 158 00:08:19,880 --> 00:08:23,560 Speaker 1: and the movie is understanding and appreciating how difficult it 159 00:08:23,720 --> 00:08:26,480 Speaker 1: might be to communicate with aliens, not to mention, like 160 00:08:26,800 --> 00:08:29,320 Speaker 1: talk about, you know, their notions of quantum mechanics, but 161 00:08:29,400 --> 00:08:32,400 Speaker 1: just like get the basics down, you know, and that's 162 00:08:32,440 --> 00:08:34,880 Speaker 1: a whole other question, you know, And maybe for today 163 00:08:34,920 --> 00:08:36,880 Speaker 1: we should put that aside with the question of whether 164 00:08:36,920 --> 00:08:40,240 Speaker 1: we could discover alien messages, whether we could develop a 165 00:08:40,240 --> 00:08:43,200 Speaker 1: common language with them. We recently had No M. Chomsky 166 00:08:43,360 --> 00:08:46,360 Speaker 1: and Kareem Jabari on the podcast to talk about, you know, 167 00:08:46,440 --> 00:08:49,840 Speaker 1: the universality of language, And something that comes up often 168 00:08:49,920 --> 00:08:54,240 Speaker 1: in these conversations is not necessarily like could we understand 169 00:08:54,280 --> 00:08:57,680 Speaker 1: their lingo and their slaying and how they communicate, but 170 00:08:57,800 --> 00:09:00,319 Speaker 1: that there might be a deeper way to communicate something 171 00:09:00,320 --> 00:09:03,360 Speaker 1: that's common, something that's universal. This is this I think 172 00:09:03,360 --> 00:09:06,199 Speaker 1: widely held belief that we can avoid this whole question 173 00:09:06,240 --> 00:09:09,200 Speaker 1: of language by focusing on the mathematics and the physics, 174 00:09:09,240 --> 00:09:12,680 Speaker 1: which might be more universal. And Carl Sagan famously argued 175 00:09:12,720 --> 00:09:16,199 Speaker 1: that we could use mathematics to find a common intellectual context. 176 00:09:16,360 --> 00:09:19,520 Speaker 1: But how much can we say about like the universality 177 00:09:19,679 --> 00:09:23,000 Speaker 1: of mathematics itself, What do we know about whether it's 178 00:09:23,080 --> 00:09:26,360 Speaker 1: likely to be just the way humans think, like an abstract, 179 00:09:26,440 --> 00:09:29,880 Speaker 1: sort of succinct way to describe the thought processes that 180 00:09:29,920 --> 00:09:33,240 Speaker 1: we have, or something that actually reflects the objective structure 181 00:09:33,320 --> 00:09:36,520 Speaker 1: of the universe. How do we probe that kind of question? Yeah, 182 00:09:36,520 --> 00:09:38,680 Speaker 1: that's that's a great question. Daniel, And this is a 183 00:09:38,720 --> 00:09:41,679 Speaker 1: whole area of really fruitful research and philosophy and the 184 00:09:41,679 --> 00:09:44,640 Speaker 1: philosophy of of mathematics, which I certainly can't claim to 185 00:09:44,640 --> 00:09:46,719 Speaker 1: be any kind of expert on, but it's it's it's 186 00:09:46,760 --> 00:09:50,320 Speaker 1: tantalizing for sure. I mean, there's this problem, right that 187 00:09:50,360 --> 00:09:53,480 Speaker 1: you might have encountered, a problem of the unreasonable effectiveness 188 00:09:53,520 --> 00:09:57,319 Speaker 1: of mathematics. And it seems kind of surprising and really 189 00:09:57,360 --> 00:10:00,240 Speaker 1: cool that mathematics turns out to be so good at 190 00:10:00,240 --> 00:10:03,640 Speaker 1: describing the physical universe that we find around us, right, 191 00:10:03,679 --> 00:10:07,720 Speaker 1: this abstract formal system that we've perhaps invented. You know, 192 00:10:07,760 --> 00:10:10,280 Speaker 1: a lot of branches of mathematics come about just by 193 00:10:10,320 --> 00:10:13,160 Speaker 1: mathematicians thinking in the abstract kind of having fun and 194 00:10:13,200 --> 00:10:15,560 Speaker 1: doing puzzles, if you like, and then turn out to 195 00:10:15,640 --> 00:10:19,360 Speaker 1: be applicable to real physical systems. And this this is 196 00:10:19,440 --> 00:10:23,120 Speaker 1: kind of remarkable and maybe something like a hint at 197 00:10:23,160 --> 00:10:25,640 Speaker 1: the fact that the universe is in a way kind 198 00:10:25,640 --> 00:10:28,920 Speaker 1: of made in these mathematical terms and there's something objective 199 00:10:28,960 --> 00:10:31,560 Speaker 1: going on here. So that's an interesting thought. Yeah, maybe 200 00:10:31,600 --> 00:10:33,880 Speaker 1: there's some hope that that could be something of a 201 00:10:34,000 --> 00:10:37,800 Speaker 1: universal that even crazy arrival type aliens might be able 202 00:10:37,800 --> 00:10:40,400 Speaker 1: to communicate with us in terms of I'd love to 203 00:10:40,400 --> 00:10:43,200 Speaker 1: believe that, and I'd love to think that mathematics is 204 00:10:43,240 --> 00:10:46,360 Speaker 1: somehow the language of the universe itself, you know that, 205 00:10:46,520 --> 00:10:49,120 Speaker 1: like if we're in a simulation and mathematics is the 206 00:10:49,120 --> 00:10:51,280 Speaker 1: way that the source code has been written in some way. 207 00:10:51,400 --> 00:10:54,400 Speaker 1: But it seems to me a little bit presumptuous, And 208 00:10:54,480 --> 00:10:57,240 Speaker 1: let me take the devil's advocate position there and argue 209 00:10:57,280 --> 00:10:59,559 Speaker 1: against it. The thing that makes me wonder about whether 210 00:10:59,600 --> 00:11:03,320 Speaker 1: mathemat x really is fundamental is not that mathematics is 211 00:11:03,360 --> 00:11:06,520 Speaker 1: not effective, because you're right, it absolutely is. It's incredible 212 00:11:06,720 --> 00:11:09,680 Speaker 1: how well our physical theories work. And I'm a particle physicist, 213 00:11:09,720 --> 00:11:12,800 Speaker 1: and we make mathematical predictions to like ten decimal places, 214 00:11:12,800 --> 00:11:14,120 Speaker 1: and we go out in the universe and we do 215 00:11:14,160 --> 00:11:16,760 Speaker 1: experiments and while they're banging on right, and that gives 216 00:11:16,800 --> 00:11:18,920 Speaker 1: you this feeling like, wow, maybe this isn't just a 217 00:11:18,960 --> 00:11:21,520 Speaker 1: description of the universe. Maybe it is the way the 218 00:11:21,600 --> 00:11:25,480 Speaker 1: universe does these calculations. But the problem with that argument 219 00:11:25,800 --> 00:11:29,559 Speaker 1: is that every theory that we have, every mathematical description 220 00:11:29,600 --> 00:11:32,400 Speaker 1: we have of the universe, we know is an effective theory, 221 00:11:32,520 --> 00:11:36,719 Speaker 1: not a fundamental theory. We know that it has domains validity. 222 00:11:36,920 --> 00:11:40,440 Speaker 1: You know. For example, Newton's theory works really really well 223 00:11:40,920 --> 00:11:43,840 Speaker 1: until we measured very precisely the orbit of mercury. We 224 00:11:43,840 --> 00:11:46,440 Speaker 1: were like, wow, this might be the way the universe works. 225 00:11:46,440 --> 00:11:49,080 Speaker 1: Maybe Newton had revealed the truth of the universe. And 226 00:11:49,120 --> 00:11:52,000 Speaker 1: so there are many theories out there that only work 227 00:11:52,080 --> 00:11:54,800 Speaker 1: in sort of a region, in under certain conditions or 228 00:11:55,040 --> 00:11:58,480 Speaker 1: in certain systems, And can you say that they are 229 00:11:58,559 --> 00:12:01,160 Speaker 1: a fundamental description of the never is a true description 230 00:12:01,160 --> 00:12:03,640 Speaker 1: of the way the universe works? Definitely not right. Newton 231 00:12:03,800 --> 00:12:06,720 Speaker 1: was not correct about the real nature of space and 232 00:12:06,840 --> 00:12:09,840 Speaker 1: time and gravity, and yet his theory worked really well. 233 00:12:09,880 --> 00:12:12,040 Speaker 1: And today we have theories that work really well, but 234 00:12:12,120 --> 00:12:15,520 Speaker 1: we suspect or we are fairly confident that they aren't 235 00:12:15,640 --> 00:12:18,199 Speaker 1: the devast theories of the universe. The current standard model, 236 00:12:18,240 --> 00:12:20,640 Speaker 1: for example, will break down at the plank scale, where 237 00:12:20,640 --> 00:12:23,200 Speaker 1: it needs a description of gravity. So how do we 238 00:12:23,240 --> 00:12:27,000 Speaker 1: know that there are mathematical descriptions that are really fundamental, 239 00:12:27,120 --> 00:12:30,280 Speaker 1: not just effective in some regime. Are we just looking 240 00:12:30,280 --> 00:12:33,480 Speaker 1: at sort of like a patchwork of mathematical ideas, not 241 00:12:33,679 --> 00:12:36,640 Speaker 1: like a true revealing of the nature of the universe. Yeah, 242 00:12:36,679 --> 00:12:39,360 Speaker 1: an interesting. Dannally a very good point that it reminds 243 00:12:39,400 --> 00:12:42,400 Speaker 1: me of a debate in the philosophy of science, realism 244 00:12:42,480 --> 00:12:45,840 Speaker 1: versus anti realism, roughly the debate over whether or not 245 00:12:45,960 --> 00:12:48,120 Speaker 1: science kind of gets that the truth of how things are. 246 00:12:48,320 --> 00:12:50,000 Speaker 1: And the anti realists say that who say that it 247 00:12:50,000 --> 00:12:52,520 Speaker 1: doesn't get the truth have an argument along those lines, right, 248 00:12:52,520 --> 00:12:55,160 Speaker 1: They say, Look, all of these past scientific theories have 249 00:12:55,240 --> 00:12:57,520 Speaker 1: proven to be false, so why could we hold out 250 00:12:57,520 --> 00:13:00,000 Speaker 1: any any hope that our current theories are anywhere near 251 00:13:00,080 --> 00:13:02,000 Speaker 1: the truth? But then the flip side of that is, 252 00:13:02,040 --> 00:13:04,400 Speaker 1: like you say, the or perhaps you alluded to that 253 00:13:04,559 --> 00:13:08,120 Speaker 1: these kind of false theories that are are mathematized as 254 00:13:08,160 --> 00:13:10,920 Speaker 1: as we've mentioned before as well, nonetheless seemed to be 255 00:13:11,120 --> 00:13:13,640 Speaker 1: kind of doing doing quite well, and we can we 256 00:13:13,679 --> 00:13:15,760 Speaker 1: can do some good work with things like Newton's theory. 257 00:13:15,760 --> 00:13:19,319 Speaker 1: We can send people into space and stuff like that. Right, Um, 258 00:13:19,400 --> 00:13:21,600 Speaker 1: So although they might be strictly speaking false, they might 259 00:13:21,600 --> 00:13:24,560 Speaker 1: be kind of getting at something that's kind of almost right. 260 00:13:24,920 --> 00:13:28,400 Speaker 1: And we might think that the better theories nonetheless preserve 261 00:13:28,559 --> 00:13:31,760 Speaker 1: something of the structure of Newton's theory. So then something 262 00:13:31,800 --> 00:13:34,520 Speaker 1: that some metaphysicians and philosophers of science have said, in 263 00:13:34,559 --> 00:13:38,040 Speaker 1: response to this kind of pessimistic argument for anti realism 264 00:13:38,040 --> 00:13:40,719 Speaker 1: and a slightly more skeptical stances, that maybe what we're 265 00:13:40,760 --> 00:13:43,720 Speaker 1: doing when we're describing the universe kind of imperfectly but 266 00:13:43,760 --> 00:13:45,319 Speaker 1: in a way that kind of works and is then 267 00:13:45,360 --> 00:13:49,280 Speaker 1: built on, is we're getting at some underlying deep structure. Right, 268 00:13:49,320 --> 00:13:52,040 Speaker 1: So then maybe maybe our mass, maybe even something like 269 00:13:52,080 --> 00:13:55,800 Speaker 1: Newton's theory is nonetheless latching onto some sort of objective 270 00:13:56,120 --> 00:13:59,720 Speaker 1: structure in a much kind of broader or deeper sense 271 00:13:59,800 --> 00:14:02,839 Speaker 1: than whether it's it's directly true, and so there might 272 00:14:02,840 --> 00:14:05,360 Speaker 1: be some some hope there that that the maths is 273 00:14:05,880 --> 00:14:09,400 Speaker 1: describing something that is fundamentally correct that's then sustained through 274 00:14:09,480 --> 00:14:12,800 Speaker 1: the theory change. The idea there, I guess is maybe 275 00:14:12,840 --> 00:14:16,600 Speaker 1: alien physicists also hit on Newton's approach before they hit 276 00:14:16,640 --> 00:14:20,600 Speaker 1: on Einstone's approach that is not just a human description 277 00:14:20,760 --> 00:14:24,360 Speaker 1: of the universe, but it really is an effective approximation 278 00:14:24,440 --> 00:14:26,320 Speaker 1: of the way the universe really works. I guess that 279 00:14:26,440 --> 00:14:28,200 Speaker 1: is that the argument. I think that I think that 280 00:14:28,280 --> 00:14:30,280 Speaker 1: might be the idea. Yeah, right, I mean, we can 281 00:14:30,320 --> 00:14:33,040 Speaker 1: also think we know that Newton's theory is false, but 282 00:14:33,040 --> 00:14:35,080 Speaker 1: what we can still wonder why it's so kind of 283 00:14:35,120 --> 00:14:38,440 Speaker 1: effective and useful for us, And perhaps an answer to 284 00:14:38,480 --> 00:14:40,240 Speaker 1: that is that it is getting at some sort of 285 00:14:40,360 --> 00:14:42,840 Speaker 1: underlying structure. In some sense, it might be kind of 286 00:14:42,880 --> 00:14:45,040 Speaker 1: slightly grappling and growing in the dark at this thing, 287 00:14:45,040 --> 00:14:46,760 Speaker 1: but it might be kind of getting close, you know. 288 00:14:47,040 --> 00:14:48,760 Speaker 1: And so that's why we might be able to nonetheless 289 00:14:48,880 --> 00:14:51,680 Speaker 1: use Newton's theory for all sorts of interests and purposes 290 00:14:51,720 --> 00:14:53,320 Speaker 1: that we have. Yeah, all right, well, I have a 291 00:14:53,320 --> 00:14:55,880 Speaker 1: lot more questions about how we might probe the universe 292 00:14:55,920 --> 00:14:58,600 Speaker 1: and how alien scientists do as well. But first let's 293 00:14:58,600 --> 00:15:13,280 Speaker 1: take a quick break. All right, we're back and we're 294 00:15:13,280 --> 00:15:16,520 Speaker 1: talking to my guests, Samuel kim Deny, a philosopher of 295 00:15:16,600 --> 00:15:20,600 Speaker 1: science and metaphysics, about how aliens might think about science. 296 00:15:20,720 --> 00:15:22,960 Speaker 1: And when we took a break there, we were examining 297 00:15:22,960 --> 00:15:26,760 Speaker 1: the question of whether our approximate theories like Newton series, 298 00:15:27,040 --> 00:15:29,880 Speaker 1: whether they're just sort of like human versions of the truth, 299 00:15:29,960 --> 00:15:33,200 Speaker 1: or whether they might be universal, you know, our alien 300 00:15:33,240 --> 00:15:36,720 Speaker 1: physicists likely to stumble into sort of the same ideas 301 00:15:36,800 --> 00:15:39,520 Speaker 1: as we are, or are these just sort of the 302 00:15:39,520 --> 00:15:42,120 Speaker 1: way the humans think about the universe. And I think 303 00:15:42,120 --> 00:15:44,320 Speaker 1: One way to maybe probe that is to think about 304 00:15:44,680 --> 00:15:47,800 Speaker 1: why it's even possible to do what Newton did. I mean, 305 00:15:47,840 --> 00:15:50,720 Speaker 1: if the universe has some fundamental theory down at the 306 00:15:50,800 --> 00:15:53,840 Speaker 1: string scale, quantum gravity, whatever is going on down there, 307 00:15:54,080 --> 00:15:58,240 Speaker 1: why isn't everything at the human scale totally chaotic? You know, 308 00:15:58,240 --> 00:16:00,800 Speaker 1: if you try to describe a hurricane in terms of 309 00:16:00,800 --> 00:16:04,240 Speaker 1: its fundamental bits, the rain drops, it's a huge difficult problem. 310 00:16:04,520 --> 00:16:07,200 Speaker 1: We don't have like a simple equation that tells you 311 00:16:07,240 --> 00:16:10,800 Speaker 1: where a hurricane is gonna land. It's a massively chaotic problem, 312 00:16:10,800 --> 00:16:13,240 Speaker 1: and you have to model every tiny little rain drop, 313 00:16:13,360 --> 00:16:15,520 Speaker 1: and rain drop moves over a meter, it could change 314 00:16:15,560 --> 00:16:17,760 Speaker 1: the entire path of the hurricane. But in our world, 315 00:16:17,760 --> 00:16:20,280 Speaker 1: it's possible to do what Newton did and describe the 316 00:16:20,320 --> 00:16:22,960 Speaker 1: path of a ball through the air without knowing anything 317 00:16:23,000 --> 00:16:25,840 Speaker 1: about quantum and gravity. Right, you can make chicken soup 318 00:16:26,000 --> 00:16:28,200 Speaker 1: without knowing what the soup is really made out of. 319 00:16:28,800 --> 00:16:31,120 Speaker 1: And to me that seems like the key there. If 320 00:16:31,200 --> 00:16:36,080 Speaker 1: these things are emerging, these descriptions, these simplified mathematical stories 321 00:16:36,160 --> 00:16:39,480 Speaker 1: the universe are universal. Everybody else should find them as well. 322 00:16:39,520 --> 00:16:42,840 Speaker 1: But do we even know why they exist? Why is 323 00:16:42,880 --> 00:16:47,480 Speaker 1: it possible to find these simplified mathematical stories of the universe. 324 00:16:47,520 --> 00:16:50,160 Speaker 1: It seems to me key to understanding whether aliens are 325 00:16:50,200 --> 00:16:52,560 Speaker 1: also going to find them. Right, Yeah, I mean again, 326 00:16:52,600 --> 00:16:55,640 Speaker 1: this is a thing that trusted the science metaphysicians really 327 00:16:55,680 --> 00:16:58,200 Speaker 1: puzzle over its Um, why do we need to have 328 00:16:58,240 --> 00:17:00,200 Speaker 1: all of the different science is? Why can't we just 329 00:17:00,280 --> 00:17:03,120 Speaker 1: have fundamental physics and maybe chemistry? Why do we need 330 00:17:03,160 --> 00:17:06,399 Speaker 1: biology and psychology and economics as well? Right, that's a 331 00:17:06,440 --> 00:17:09,240 Speaker 1: little bit aggressive. Why don't we need anything but physics? Really, 332 00:17:09,240 --> 00:17:13,879 Speaker 1: physics is the only side It could be taken like that, 333 00:17:13,920 --> 00:17:17,320 Speaker 1: but it could more be um, yeah, a puzzlement once 334 00:17:17,359 --> 00:17:19,560 Speaker 1: once we kind of realize or think that, hey, it 335 00:17:19,600 --> 00:17:21,960 Speaker 1: looks like everything is kind of composed out of fundamental 336 00:17:22,000 --> 00:17:24,320 Speaker 1: particles or fields or something like that, Why can't we 337 00:17:24,359 --> 00:17:27,560 Speaker 1: just do it all in fundamental terms? And yeah, I think, 338 00:17:27,680 --> 00:17:30,160 Speaker 1: like you say, it's something of a mystery. I don't 339 00:17:30,160 --> 00:17:31,680 Speaker 1: know if this is really an answer, but this is 340 00:17:31,720 --> 00:17:34,160 Speaker 1: just kind of rephrasing the issue. But what what sort 341 00:17:34,240 --> 00:17:37,400 Speaker 1: seems to happen is that we can effectively abstract away 342 00:17:37,440 --> 00:17:39,760 Speaker 1: from from certain details. Right because when we look at 343 00:17:39,840 --> 00:17:42,040 Speaker 1: the level of the weather, systems, or or the ball 344 00:17:42,119 --> 00:17:45,280 Speaker 1: flying through through space. We don't need to think about 345 00:17:45,280 --> 00:17:47,600 Speaker 1: certain details at the fundamental level. We can kind of 346 00:17:47,600 --> 00:17:50,520 Speaker 1: coarse grain the information and then that presents a picture 347 00:17:50,560 --> 00:17:54,520 Speaker 1: that's far more useful and tractable for us given our interests. Right, 348 00:17:54,640 --> 00:17:56,160 Speaker 1: And this is what we do, and this is how 349 00:17:56,160 --> 00:17:57,840 Speaker 1: we how we navigate the world. Like you say, we 350 00:17:57,840 --> 00:18:00,440 Speaker 1: can we can make our chicken soup without worry about 351 00:18:00,440 --> 00:18:03,520 Speaker 1: what the what the electrons all the fields are doing. Right, 352 00:18:03,720 --> 00:18:06,080 Speaker 1: but you said something really interesting there, you said, based 353 00:18:06,119 --> 00:18:09,160 Speaker 1: on what our interests are. It makes me wonder if 354 00:18:09,240 --> 00:18:12,119 Speaker 1: the universe is sort of like Russiman. You know what 355 00:18:12,280 --> 00:18:14,439 Speaker 1: if we look at one system and we say, oh, 356 00:18:14,480 --> 00:18:16,840 Speaker 1: the interesting thing here is a ball flying through the air, 357 00:18:16,920 --> 00:18:19,399 Speaker 1: and look, I can tell a simple mathematical story about it, 358 00:18:19,600 --> 00:18:22,160 Speaker 1: and an alien physicists would be like ball, what even 359 00:18:22,280 --> 00:18:24,400 Speaker 1: is that? I'm more interested in the flow of these 360 00:18:24,400 --> 00:18:26,400 Speaker 1: particles over here, and I call that a blah blah 361 00:18:26,400 --> 00:18:28,720 Speaker 1: blah And here's my equation for the blah blah blah 362 00:18:28,880 --> 00:18:31,199 Speaker 1: and it's beautiful. And you know, is there there a 363 00:18:31,280 --> 00:18:34,840 Speaker 1: patchwork of mathematical stories that are only interesting to us? 364 00:18:35,480 --> 00:18:37,919 Speaker 1: Or are these stories likely to be universal. And I 365 00:18:37,960 --> 00:18:41,040 Speaker 1: know that the real answer waits until we meet the 366 00:18:41,040 --> 00:18:43,200 Speaker 1: aliens and we've talked science with them and we figure 367 00:18:43,200 --> 00:18:46,080 Speaker 1: out if they've developed completely independent branches of science. But 368 00:18:46,119 --> 00:18:49,520 Speaker 1: I wonder you think it's possible to approach that question, 369 00:18:49,560 --> 00:18:53,200 Speaker 1: to address that question today before we've met the aliens, 370 00:18:53,240 --> 00:18:55,760 Speaker 1: just by looking at the structure of our theories and 371 00:18:56,000 --> 00:18:58,440 Speaker 1: looking for a hints that these things might be arbitrary 372 00:18:58,560 --> 00:19:01,480 Speaker 1: or might be universal. How we possibly pull those things 373 00:19:01,520 --> 00:19:05,080 Speaker 1: apart today before we get to talk to the aliens? Nice? 374 00:19:05,160 --> 00:19:09,760 Speaker 1: I mean, I happened to be somewhat skeptical about the 375 00:19:09,800 --> 00:19:13,160 Speaker 1: idea that there really is an objective way of kind 376 00:19:13,200 --> 00:19:16,040 Speaker 1: of I guess, so if we think about the ball 377 00:19:16,119 --> 00:19:17,760 Speaker 1: or the chicken, to talk of that as like a 378 00:19:17,760 --> 00:19:20,360 Speaker 1: way of course graining the low the low level information 379 00:19:20,400 --> 00:19:22,959 Speaker 1: to suit our interests, I'm kind of skeptical that there 380 00:19:23,040 --> 00:19:25,840 Speaker 1: is an objectively right or best way to do that. 381 00:19:26,040 --> 00:19:27,880 Speaker 1: And it seems kind of plausible to me that, yeah, 382 00:19:27,960 --> 00:19:31,080 Speaker 1: the aliens might be interested in some very different course grainings. Right, 383 00:19:31,119 --> 00:19:33,640 Speaker 1: So we're interested in the lump of matter that kind 384 00:19:33,640 --> 00:19:35,840 Speaker 1: of corresponds to what we call the ball, But why 385 00:19:35,880 --> 00:19:38,040 Speaker 1: not be interested in the lump of matter that we 386 00:19:38,119 --> 00:19:42,040 Speaker 1: call the ball and also my nose every Tuesday. Right, 387 00:19:43,400 --> 00:19:45,040 Speaker 1: this would be a very strange kind of thing to 388 00:19:45,040 --> 00:19:47,760 Speaker 1: be interested in because it kind of jumps over time 389 00:19:47,800 --> 00:19:50,199 Speaker 1: and space in strange sorts of ways. But look, I 390 00:19:50,240 --> 00:19:53,000 Speaker 1: can I can define that object, right, this lump of 391 00:19:53,000 --> 00:19:55,520 Speaker 1: matter that we call the ball and my nose on Tuesdays? 392 00:19:55,600 --> 00:19:58,640 Speaker 1: And why not try and describe the behavior of that thing. 393 00:19:58,800 --> 00:20:00,800 Speaker 1: Maybe that's a bit too silly, but I think that 394 00:20:00,880 --> 00:20:03,440 Speaker 1: the point is, Um, it turns out to be very 395 00:20:03,440 --> 00:20:09,119 Speaker 1: difficult to say why objectively we should be interested in 396 00:20:09,160 --> 00:20:11,479 Speaker 1: the things that we are interested in. And and do 397 00:20:11,520 --> 00:20:14,159 Speaker 1: we think that an alien species would be wrong for 398 00:20:14,200 --> 00:20:17,160 Speaker 1: having some very interested in very different kind of course 399 00:20:17,160 --> 00:20:19,879 Speaker 1: grainings or would it be impossible for aliens to have 400 00:20:20,240 --> 00:20:23,960 Speaker 1: interests in very different kinds of course grainings? Um, I'm 401 00:20:24,000 --> 00:20:26,560 Speaker 1: not sure. I don't see why it would be wrong 402 00:20:26,600 --> 00:20:29,280 Speaker 1: if they had these different interests. It doesn't strike me 403 00:20:29,320 --> 00:20:31,639 Speaker 1: as impossibly that if they're again, like going back to 404 00:20:31,640 --> 00:20:34,040 Speaker 1: what we're saying at the beginning, if their modes of 405 00:20:34,119 --> 00:20:37,760 Speaker 1: perceiving that their central sense experiences were very different to ours, 406 00:20:37,880 --> 00:20:40,280 Speaker 1: or maybe if they perceived time very differently than we did. 407 00:20:40,680 --> 00:20:42,720 Speaker 1: Why not? You know, right? And to me it goes 408 00:20:42,800 --> 00:20:45,080 Speaker 1: to really the heart of the question of the human 409 00:20:45,200 --> 00:20:47,880 Speaker 1: experience and the context of it. In the same way 410 00:20:47,920 --> 00:20:50,840 Speaker 1: that we want to know are we alone? Because we 411 00:20:50,880 --> 00:20:54,200 Speaker 1: want to understand, like is life rare? And we also 412 00:20:54,240 --> 00:20:56,600 Speaker 1: like to know are there other kinds of life? And 413 00:20:56,680 --> 00:20:58,760 Speaker 1: the biology have a lots of different options and we 414 00:20:58,840 --> 00:21:01,040 Speaker 1: just got one? Or is this basically the only way 415 00:21:01,119 --> 00:21:03,719 Speaker 1: it can work? Meeting aliens can answer that question, and 416 00:21:03,800 --> 00:21:07,800 Speaker 1: in the same way meeting alien physicists could tell us like, oh, look, 417 00:21:07,920 --> 00:21:09,720 Speaker 1: it turns out they got their own Newton and they 418 00:21:09,760 --> 00:21:11,879 Speaker 1: got their own Einstein, and this is the path you 419 00:21:11,960 --> 00:21:14,760 Speaker 1: take to understanding the universe and it basically everybody follows 420 00:21:14,760 --> 00:21:17,520 Speaker 1: the same path, or you know, did they take a 421 00:21:17,560 --> 00:21:20,600 Speaker 1: completely separate path? And I thought, experiment I'd love to 422 00:21:20,680 --> 00:21:24,000 Speaker 1: do in reality is to take like a thousand earths 423 00:21:24,080 --> 00:21:28,280 Speaker 1: and have humans evolve intelligently and then let science progress independently. 424 00:21:28,640 --> 00:21:31,520 Speaker 1: You know, Newton almost didn't even become a scientist. What 425 00:21:31,560 --> 00:21:34,639 Speaker 1: would have happened if he hadn't, if we hadn't had Einstein, 426 00:21:34,720 --> 00:21:37,000 Speaker 1: or if somebody else had been even smarter? You know, 427 00:21:37,080 --> 00:21:39,199 Speaker 1: it feels to me like the path of human science 428 00:21:39,240 --> 00:21:43,240 Speaker 1: rests so much on these tiny moments, these tiny accidents, 429 00:21:43,560 --> 00:21:45,600 Speaker 1: these tiny choices that people make, that it could have 430 00:21:45,720 --> 00:21:48,040 Speaker 1: very well gone a different way, and we have really 431 00:21:48,080 --> 00:21:50,280 Speaker 1: no way to probe, you know, the different paths that 432 00:21:50,359 --> 00:21:53,160 Speaker 1: might have taken, because we haven't met those aliens yet. 433 00:21:53,240 --> 00:21:55,159 Speaker 1: One way I thought about to probe that is to 434 00:21:55,280 --> 00:21:58,239 Speaker 1: look at this sort of history of the development of 435 00:21:58,440 --> 00:22:01,960 Speaker 1: intellectual scientific thought here on Earth. Do you know anything 436 00:22:01,960 --> 00:22:05,159 Speaker 1: about like the history of you know, Mayan science and 437 00:22:05,320 --> 00:22:08,800 Speaker 1: Chinese science and Egyptian astronomy, and whether they can tell 438 00:22:08,880 --> 00:22:12,800 Speaker 1: us whether independent groups of humans tend to come to 439 00:22:12,840 --> 00:22:15,280 Speaker 1: the same ways of thinking about the universe, or whether 440 00:22:15,520 --> 00:22:18,399 Speaker 1: there really are divergent ways to attack this problem. I 441 00:22:18,480 --> 00:22:20,600 Speaker 1: think that's the exactly the right way to kind of 442 00:22:20,600 --> 00:22:22,960 Speaker 1: go about investigating this thing a bit more empirically. Yeah, 443 00:22:22,960 --> 00:22:25,760 Speaker 1: that sounds like a great idea to me. Unfortunately, I 444 00:22:25,800 --> 00:22:28,520 Speaker 1: don't know about any investigations along those lines, although I'm 445 00:22:28,560 --> 00:22:31,560 Speaker 1: sure there are some. Something kind of similar that I 446 00:22:31,600 --> 00:22:35,800 Speaker 1: have heard about in philosophy is there's a recent movement 447 00:22:35,880 --> 00:22:40,960 Speaker 1: in experimental called experimental philosophy, which basically surveys the kind 448 00:22:41,000 --> 00:22:45,280 Speaker 1: of philosophical intuitions of the folks on various um philosophical 449 00:22:45,320 --> 00:22:48,080 Speaker 1: puzzles and things like that. So philosophy has kind of 450 00:22:48,280 --> 00:22:51,760 Speaker 1: um philosophical intuition has been kind of put in the 451 00:22:51,800 --> 00:22:54,280 Speaker 1: spotlight recently because it's like, hang on a minute, these 452 00:22:54,320 --> 00:22:57,439 Speaker 1: are the intuitions generally seemed to the interesting intuitions of 453 00:22:57,680 --> 00:23:01,119 Speaker 1: Western philosophers, and maybe they wouldn't be shared across the board, 454 00:23:01,520 --> 00:23:03,680 Speaker 1: or or they wouldn't be shared even just by people 455 00:23:03,680 --> 00:23:06,520 Speaker 1: who aren't kind of indoctrinated into the academy as it were. 456 00:23:06,640 --> 00:23:09,359 Speaker 1: And the experimental philosophers have done some work in this area, 457 00:23:09,359 --> 00:23:12,879 Speaker 1: and I think they've uncovered more divergence in kind of 458 00:23:12,920 --> 00:23:16,480 Speaker 1: philosophical intuitions than the kind of Western cannon would have 459 00:23:16,560 --> 00:23:18,520 Speaker 1: us believe. So I think there is some good reason 460 00:23:18,600 --> 00:23:21,040 Speaker 1: to think that something similar might be the case with 461 00:23:21,280 --> 00:23:24,080 Speaker 1: science as well, right, And I mean, I suppose another thing. 462 00:23:24,320 --> 00:23:27,440 Speaker 1: I guess why I think this is relevant is because 463 00:23:27,480 --> 00:23:30,840 Speaker 1: I think, really at the fundamental level, you can't draw 464 00:23:31,200 --> 00:23:35,000 Speaker 1: sharp dividing lines between a kind of philosophical blue sky 465 00:23:35,080 --> 00:23:38,359 Speaker 1: approach to thinking about the world and the scientific approach. 466 00:23:38,400 --> 00:23:40,560 Speaker 1: We've all got to kind of start somewhere. And so 467 00:23:40,680 --> 00:23:43,000 Speaker 1: if there's some evidence to suggest that these kind of 468 00:23:43,480 --> 00:23:48,879 Speaker 1: broad philosophical intuitions on big questions are quite divergent between 469 00:23:48,880 --> 00:23:51,920 Speaker 1: different people and different cultures, then I don't see why 470 00:23:51,960 --> 00:23:55,200 Speaker 1: that that wouldn't maybe lead us to think that plausibly 471 00:23:55,920 --> 00:23:58,199 Speaker 1: different different ways of doing science and different kind of 472 00:23:58,200 --> 00:24:02,880 Speaker 1: foundational thoughts and intuitions on scientific issues might vary quite 473 00:24:02,960 --> 00:24:06,400 Speaker 1: radically across people in different cultures as well. Yeah, that's 474 00:24:06,440 --> 00:24:09,879 Speaker 1: the thing. Well, we'll have a scientific anthropologist on to 475 00:24:09,960 --> 00:24:13,120 Speaker 1: talk about how indigenous cultures do science and the histort 476 00:24:13,119 --> 00:24:15,120 Speaker 1: of history of the development there. But I think that'd 477 00:24:15,119 --> 00:24:16,680 Speaker 1: be a lot of fun. I want to turn us 478 00:24:16,680 --> 00:24:19,240 Speaker 1: back to the question we were discussing a moment ago, 479 00:24:19,320 --> 00:24:23,920 Speaker 1: which is, you know, whether these emergent theories, these mathematical 480 00:24:24,000 --> 00:24:26,719 Speaker 1: descriptions of the world that we see it our universal 481 00:24:27,040 --> 00:24:30,040 Speaker 1: or whether they're just sort of culturally dependent and could 482 00:24:30,080 --> 00:24:33,120 Speaker 1: be different for aliens. But let's zoom down and talk 483 00:24:33,160 --> 00:24:36,240 Speaker 1: about maybe like the fundamental theory of the universe. Some 484 00:24:36,359 --> 00:24:38,840 Speaker 1: listeners out there might think, well, perhaps we have different 485 00:24:38,880 --> 00:24:42,080 Speaker 1: descriptions of balls versus noses, but at its heart, the 486 00:24:42,200 --> 00:24:45,760 Speaker 1: universe is a certain way there are fundamental vibrating strings, 487 00:24:45,880 --> 00:24:48,719 Speaker 1: or there are space pixels or something at the quantum 488 00:24:48,720 --> 00:24:51,080 Speaker 1: gravity level. And what if we all zoom down there, 489 00:24:51,119 --> 00:24:54,600 Speaker 1: what would we inevitably find the same description of the 490 00:24:54,640 --> 00:24:58,239 Speaker 1: universe because it is one way. So Kareem Jabari from 491 00:24:58,280 --> 00:25:00,320 Speaker 1: the Institute of Future Studies was on the part cast 492 00:25:00,320 --> 00:25:02,119 Speaker 1: a couple of weeks ago. He made a claim that 493 00:25:02,119 --> 00:25:04,600 Speaker 1: I found a bit shocking. He said that you could 494 00:25:04,600 --> 00:25:08,600 Speaker 1: have two fundamental theories of the universe that both work 495 00:25:08,920 --> 00:25:11,720 Speaker 1: in the sense that they succeed in describing what we see, 496 00:25:12,240 --> 00:25:16,359 Speaker 1: but internally are fundamentally different pictures of the universe, or 497 00:25:16,400 --> 00:25:21,400 Speaker 1: like completely different mental descriptions and mental structures telling us 498 00:25:21,400 --> 00:25:23,720 Speaker 1: a story about what's happening at the deepest scale. Do 499 00:25:23,720 --> 00:25:25,480 Speaker 1: you agree with that? Do you think it's possible to 500 00:25:25,520 --> 00:25:30,840 Speaker 1: have multiple accurate theories of the fundamental nature of the universe? Yeah, 501 00:25:31,040 --> 00:25:33,680 Speaker 1: very interesting, I think nice. I like the approach there 502 00:25:33,720 --> 00:25:35,719 Speaker 1: to think, Okay, maybe maybe if we zoom down then 503 00:25:35,720 --> 00:25:38,159 Speaker 1: we can then we can hope for some more objectivity. 504 00:25:38,320 --> 00:25:40,359 Speaker 1: I suppose one thing that comes to my mind is 505 00:25:40,760 --> 00:25:43,560 Speaker 1: that kind of approach hopes or assumes that there is 506 00:25:43,600 --> 00:25:47,080 Speaker 1: such a thing as a fundamental level. For all we know, 507 00:25:47,280 --> 00:25:50,080 Speaker 1: it could be infinitely infinitely divisible all the way all 508 00:25:50,119 --> 00:25:51,719 Speaker 1: the way down right, And then I don't know, if 509 00:25:51,720 --> 00:25:53,600 Speaker 1: we'd be in trouble. Then that might kind of scupperro 510 00:25:54,480 --> 00:25:57,359 Speaker 1: our aspirations for objectivity. It might mean a lot of 511 00:25:57,359 --> 00:25:59,520 Speaker 1: work for particle physicists for a long time, though we 512 00:25:59,640 --> 00:26:06,520 Speaker 1: just keep building bigger and bigger Adams measures potentially good news. Then, Yeah, 513 00:26:06,640 --> 00:26:09,200 Speaker 1: so that's something that I would worry a bit about. 514 00:26:09,320 --> 00:26:11,960 Speaker 1: I mean, so I suppose the worry, the kind of 515 00:26:12,119 --> 00:26:17,120 Speaker 1: anti objectivist or pragmatist approach or kind of worry, would 516 00:26:17,119 --> 00:26:19,040 Speaker 1: be that maybe all there is to the universe is 517 00:26:19,119 --> 00:26:22,480 Speaker 1: just some kind of homogeneous blob of matter, and we 518 00:26:22,600 --> 00:26:25,120 Speaker 1: just kind of cut it up in ways that serve 519 00:26:25,200 --> 00:26:28,480 Speaker 1: our interests. And so then you're perhaps counterproposal here is, 520 00:26:28,520 --> 00:26:29,720 Speaker 1: But but what if we could just get to the 521 00:26:29,800 --> 00:26:33,399 Speaker 1: very nature of the homogeneous blob matter stuff itself. Yeah, 522 00:26:33,520 --> 00:26:36,439 Speaker 1: I don't know. Perhaps it depends. It depends what we 523 00:26:36,480 --> 00:26:39,840 Speaker 1: mean by homogeneous exactly, I suppose, and how homogeneous this 524 00:26:39,840 --> 00:26:42,160 Speaker 1: this blob stuff could be, and what they really would 525 00:26:42,160 --> 00:26:44,879 Speaker 1: be to say about it, independently of how we carve 526 00:26:44,920 --> 00:26:47,879 Speaker 1: it up. So I think it's it's it's the right 527 00:26:47,920 --> 00:26:49,879 Speaker 1: way to go. But I think it depends on on 528 00:26:49,920 --> 00:26:51,560 Speaker 1: a fair amount of kind of hope that there is 529 00:26:51,600 --> 00:26:54,520 Speaker 1: going to be some fundamental structure beyond which we can't 530 00:26:54,560 --> 00:26:57,159 Speaker 1: make any further subdivisions, and that it's going to be 531 00:26:57,240 --> 00:26:59,280 Speaker 1: some way that we're going to be able to latch onto. 532 00:26:59,320 --> 00:27:01,840 Speaker 1: And may be I think that's more likely, but I'm 533 00:27:01,840 --> 00:27:04,760 Speaker 1: a little bit skeptical, as perhaps you can you can sense, well, 534 00:27:04,800 --> 00:27:07,880 Speaker 1: you know, my fantasy is that aliens come and they've 535 00:27:07,920 --> 00:27:10,240 Speaker 1: been thinking about physics the way we have. They're just 536 00:27:10,280 --> 00:27:13,040 Speaker 1: like a million years advanced, and they can like guide 537 00:27:13,080 --> 00:27:15,359 Speaker 1: us through what would have taken us a million years 538 00:27:15,400 --> 00:27:17,639 Speaker 1: to figure out in just a hundred years and we 539 00:27:17,880 --> 00:27:20,640 Speaker 1: zoom forwards, you know, But that relies on us having 540 00:27:20,640 --> 00:27:23,480 Speaker 1: sort of the same principles. And the flip side of that, 541 00:27:23,560 --> 00:27:26,920 Speaker 1: my nightmare scenario is that there is no fundamental true 542 00:27:26,920 --> 00:27:30,159 Speaker 1: description of the universe, and that everything we have learned 543 00:27:30,600 --> 00:27:33,600 Speaker 1: is just this like patchwork of effective theories or like 544 00:27:33,800 --> 00:27:36,000 Speaker 1: a ladder of effective theories, where we have like a 545 00:27:36,040 --> 00:27:38,920 Speaker 1: description at the galaxy scale, and they have a description 546 00:27:38,960 --> 00:27:41,240 Speaker 1: at the solar system scale and at the human scale, 547 00:27:41,240 --> 00:27:43,240 Speaker 1: and at the atom scale and at the quark scale. 548 00:27:43,359 --> 00:27:45,800 Speaker 1: None of these things are like deeply true. They're just 549 00:27:45,880 --> 00:27:49,879 Speaker 1: like our mathematical stories about the noses we find interesting. 550 00:27:50,160 --> 00:27:52,560 Speaker 1: And aliens might have their own ladder, they might pick 551 00:27:52,640 --> 00:27:55,919 Speaker 1: different scales to explore, they might tell totally different stories. 552 00:27:55,960 --> 00:27:59,240 Speaker 1: And so when we go to that first interstellar physics 553 00:27:59,240 --> 00:28:01,840 Speaker 1: conference to show your notes that we basically have nothing 554 00:28:01,880 --> 00:28:05,240 Speaker 1: in common with these folks, and I wonder what we 555 00:28:05,280 --> 00:28:07,359 Speaker 1: could learn at that point. You know, you work on 556 00:28:07,400 --> 00:28:11,200 Speaker 1: this project of unifying the sciences of your metascience project. 557 00:28:11,440 --> 00:28:13,320 Speaker 1: If we thought about, like what it might be possible 558 00:28:13,359 --> 00:28:17,760 Speaker 1: to try to incorporate a new emergent theory that sort 559 00:28:17,760 --> 00:28:21,199 Speaker 1: of straddles are various sciences into our structure, Like, how 560 00:28:21,240 --> 00:28:24,240 Speaker 1: do we absorb that into our sort of mental canon 561 00:28:24,320 --> 00:28:27,440 Speaker 1: and make use of it? If the aliens are fascinated 562 00:28:27,480 --> 00:28:29,800 Speaker 1: in this thing that we've never even thought about, Yeah, 563 00:28:29,920 --> 00:28:33,960 Speaker 1: very interesting. I mean, I certainly don't share your your 564 00:28:33,960 --> 00:28:37,000 Speaker 1: concern with with the so called nightmare scenario. That doesn't 565 00:28:37,040 --> 00:28:39,280 Speaker 1: necessarily seem worrying to me. I mean, for sure, it 566 00:28:39,280 --> 00:28:43,240 Speaker 1: seems threatening to a certain sort of hypothesis, something along 567 00:28:43,280 --> 00:28:45,920 Speaker 1: the lines of, yeah, that the sciences are all unified, 568 00:28:45,960 --> 00:28:48,640 Speaker 1: and they're all kind of ultimately getting at one fundamental 569 00:28:48,720 --> 00:28:52,520 Speaker 1: objective truth, and so one could think that that situation 570 00:28:52,560 --> 00:28:55,680 Speaker 1: would be evidence for a kind of radical disunity of 571 00:28:55,680 --> 00:28:57,880 Speaker 1: the sciences. And I take it that that that's the 572 00:28:57,960 --> 00:29:00,720 Speaker 1: kind of thing that you're you're finding night Marrish, But 573 00:29:00,800 --> 00:29:03,120 Speaker 1: why right like that that would be an interesting empirical 574 00:29:03,120 --> 00:29:05,360 Speaker 1: discovery and its own right, And so why not just 575 00:29:05,560 --> 00:29:07,600 Speaker 1: kind of wonder at that, right that that sounds that 576 00:29:07,640 --> 00:29:10,000 Speaker 1: seems pretty interesting to me. That would be a nice 577 00:29:10,000 --> 00:29:12,360 Speaker 1: meal for the philosophers if it would be disappointing for 578 00:29:12,400 --> 00:29:15,680 Speaker 1: the physicists, right, Yeah, Well, look, I mean I'm not 579 00:29:15,760 --> 00:29:18,040 Speaker 1: particularly confident about this, but I think there are a 580 00:29:18,080 --> 00:29:21,480 Speaker 1: great many philosophers, maybe the majority, who probably do hold 581 00:29:21,480 --> 00:29:23,400 Speaker 1: out for something like the unity that you That you 582 00:29:23,480 --> 00:29:26,239 Speaker 1: sounded like you were keen on there. So then your 583 00:29:26,280 --> 00:29:28,200 Speaker 1: other question was, like, Okay, if if we did find 584 00:29:28,240 --> 00:29:31,240 Speaker 1: these these aliens who had this very radically way, a 585 00:29:31,320 --> 00:29:33,520 Speaker 1: different way of thinking about the universe and carving things 586 00:29:33,560 --> 00:29:36,480 Speaker 1: up and doing the science, what could we learn from that? Well, again, 587 00:29:36,480 --> 00:29:39,720 Speaker 1: that that would strike me as a very interesting empirical 588 00:29:39,760 --> 00:29:43,480 Speaker 1: discovery in its own right, and it looks like it 589 00:29:43,520 --> 00:29:46,120 Speaker 1: would tell us something along the lines of, you know, 590 00:29:46,320 --> 00:29:49,960 Speaker 1: what's kind of important when we're doing science is doing 591 00:29:50,000 --> 00:29:52,680 Speaker 1: something and kind of carving up the world and thinking 592 00:29:52,680 --> 00:29:54,800 Speaker 1: about the world in a way that that suits us. 593 00:29:54,920 --> 00:29:57,440 Speaker 1: So then when we're doing science, we're kind of learning 594 00:29:57,440 --> 00:30:00,720 Speaker 1: as much about ourselves as we are about the universe. 595 00:30:01,480 --> 00:30:03,680 Speaker 1: And again that that seems kind of okay, so me, 596 00:30:03,800 --> 00:30:07,440 Speaker 1: maybe it's not what most scientists have directly in mind 597 00:30:07,440 --> 00:30:09,800 Speaker 1: when they're doing science, but that seems again like an 598 00:30:09,800 --> 00:30:12,560 Speaker 1: interesting discovery on a very very worthwhile pursuit to find 599 00:30:12,560 --> 00:30:15,080 Speaker 1: out about what we like as beings and how we 600 00:30:15,200 --> 00:30:18,720 Speaker 1: carve up the universe just to suit our needs and interests. Absolutely, 601 00:30:18,760 --> 00:30:21,440 Speaker 1: it's like if we meet the Aliens and we discover 602 00:30:21,560 --> 00:30:24,400 Speaker 1: they don't like hamburgers or pizza. They've invented this other 603 00:30:24,440 --> 00:30:26,320 Speaker 1: weird kind of food, and that tells us something about 604 00:30:26,320 --> 00:30:28,840 Speaker 1: the aliens, and you know, that's why you go traveling 605 00:30:28,880 --> 00:30:31,000 Speaker 1: to eat weird kinds of food. That tells you about 606 00:30:31,000 --> 00:30:33,560 Speaker 1: what those people are like. And but their music is 607 00:30:33,600 --> 00:30:36,320 Speaker 1: like it does. It's an insight into that culture. And 608 00:30:36,760 --> 00:30:40,120 Speaker 1: that's only possible if we have enough in common to 609 00:30:40,280 --> 00:30:42,560 Speaker 1: even really understand it, you know, to understand, Oh, this 610 00:30:42,640 --> 00:30:45,120 Speaker 1: is a science question, and he raise your answer. I 611 00:30:45,160 --> 00:30:47,240 Speaker 1: want to turn a little bit to that sort of question. 612 00:30:47,320 --> 00:30:50,680 Speaker 1: Like we talked earlier about whether it's likely that aliens 613 00:30:50,720 --> 00:30:54,000 Speaker 1: even have mathematics, and whether that's universal or not. What 614 00:30:54,080 --> 00:30:57,840 Speaker 1: about the other question of whether aliens are even doing science, 615 00:30:58,040 --> 00:31:02,000 Speaker 1: like a good science itself be a fundamentally human pursuit, 616 00:31:02,480 --> 00:31:04,080 Speaker 1: not in the sense that we might be the only 617 00:31:04,240 --> 00:31:06,640 Speaker 1: curious people about the universe, but you know, science is 618 00:31:06,680 --> 00:31:09,080 Speaker 1: something we've only been doing in this form for a 619 00:31:09,120 --> 00:31:13,080 Speaker 1: few hundred years. Isn't it possible to have a technological 620 00:31:13,120 --> 00:31:17,120 Speaker 1: civilization that doesn't use this particular method of building internal 621 00:31:17,200 --> 00:31:20,200 Speaker 1: mathematical models to describe the universe in order to make 622 00:31:20,240 --> 00:31:23,560 Speaker 1: technological achievements? Do philosophers think about this question and the 623 00:31:23,640 --> 00:31:26,720 Speaker 1: universality of science itself, Yeah, for sure. I mean now, 624 00:31:26,720 --> 00:31:30,040 Speaker 1: I am tempted to give a very stereotypical philosopher's answer 625 00:31:30,080 --> 00:31:31,880 Speaker 1: to this thing, which is like, come on, we we 626 00:31:31,920 --> 00:31:34,440 Speaker 1: don't really know what science is. We can't demarcate between 627 00:31:34,440 --> 00:31:38,120 Speaker 1: science and non science and so and so that would 628 00:31:38,120 --> 00:31:39,960 Speaker 1: be a kind of a deflection of the of the question. 629 00:31:40,000 --> 00:31:43,560 Speaker 1: I suppose. But I think ultimately the kind of the 630 00:31:43,640 --> 00:31:46,920 Speaker 1: history of this topic of trying to kind of define 631 00:31:46,960 --> 00:31:50,480 Speaker 1: what constitutes science shows that that that's that's hard, if 632 00:31:50,560 --> 00:31:53,920 Speaker 1: not impossible, to do, right, And so given that observation, 633 00:31:54,000 --> 00:31:57,520 Speaker 1: I would certainly be reluctant to rule out whatever these 634 00:31:57,560 --> 00:32:00,400 Speaker 1: aliens are doing is as counting as science, because we're 635 00:32:00,400 --> 00:32:02,720 Speaker 1: not really sure where to draw the line anyway, right, 636 00:32:02,800 --> 00:32:07,280 Speaker 1: But perhaps more positively, I suppose the point just is, well, 637 00:32:07,320 --> 00:32:09,560 Speaker 1: we should be kind of quite broad and quite permissive 638 00:32:09,760 --> 00:32:12,600 Speaker 1: in what we mean by science. And it seems plausible 639 00:32:12,680 --> 00:32:16,840 Speaker 1: that even if these things were radically differently kind of 640 00:32:16,880 --> 00:32:20,640 Speaker 1: cognitively wired than we are, if they're going about trying 641 00:32:20,680 --> 00:32:23,080 Speaker 1: to kind of you know, find their way in the universe, 642 00:32:23,080 --> 00:32:26,760 Speaker 1: build machines that suit their interests, inquire into questions they 643 00:32:26,800 --> 00:32:30,719 Speaker 1: find interesting and fascinating, then then why not call that science? Right? 644 00:32:30,960 --> 00:32:33,880 Speaker 1: But I mean, maybe that's not quite what you're getting at. 645 00:32:33,880 --> 00:32:36,640 Speaker 1: Maybe what you're getting out was more with the science 646 00:32:36,680 --> 00:32:40,280 Speaker 1: that they're doing be sufficiently similar to our science for 647 00:32:40,320 --> 00:32:42,640 Speaker 1: there to be any interesting points of contact between us 648 00:32:42,640 --> 00:32:44,880 Speaker 1: and them. Was that more what you had in mind? Absolutely, 649 00:32:45,000 --> 00:32:46,760 Speaker 1: And I want to dig into that a lot more 650 00:32:46,760 --> 00:33:02,320 Speaker 1: and would first take another as ssured break. All right, 651 00:33:02,360 --> 00:33:06,400 Speaker 1: we're back and we're talking to philosophers science and metaphysics. 652 00:33:06,640 --> 00:33:10,600 Speaker 1: Samuel can deny about the possibility of talking to aliens 653 00:33:10,760 --> 00:33:13,960 Speaker 1: about science, learning from them, or maybe just being puzzled 654 00:33:13,960 --> 00:33:16,040 Speaker 1: at the way they think about the universe. And when 655 00:33:16,080 --> 00:33:18,160 Speaker 1: we broke off, we were talking about whether or not 656 00:33:18,240 --> 00:33:21,800 Speaker 1: aliens do something that we recognize as science. And you're right, 657 00:33:21,840 --> 00:33:24,000 Speaker 1: it's not about like whether or not we can officially 658 00:33:24,040 --> 00:33:26,920 Speaker 1: call what they are doing science. It's about whether what 659 00:33:27,000 --> 00:33:29,880 Speaker 1: they're doing is close enough to what we're doing that 660 00:33:29,920 --> 00:33:32,280 Speaker 1: we could learn from them. I guess my brain naturally 661 00:33:32,280 --> 00:33:35,240 Speaker 1: goes to these nightmare scenarios where, for example, we meet 662 00:33:35,360 --> 00:33:39,000 Speaker 1: starfaring aliens. They come to Earth in their spaceships that 663 00:33:39,240 --> 00:33:42,320 Speaker 1: have crossed the cosmos because they've developed warp drives, and 664 00:33:42,320 --> 00:33:44,800 Speaker 1: our first question is, of course, how does your warp 665 00:33:44,880 --> 00:33:48,040 Speaker 1: drive work? But I imagine maybe there are species that 666 00:33:48,080 --> 00:33:52,960 Speaker 1: have developed technology not through the methodical development of physical models, 667 00:33:53,240 --> 00:33:55,960 Speaker 1: but just sort of by trial and error. I think about, 668 00:33:56,000 --> 00:33:59,080 Speaker 1: for example, you know, the swords smiths of ancient Japan 669 00:33:59,360 --> 00:34:02,280 Speaker 1: or Spain or whatever. They didn't have an understanding of 670 00:34:02,440 --> 00:34:06,479 Speaker 1: why their technique made the metal extra hard. You know, 671 00:34:06,520 --> 00:34:08,960 Speaker 1: they developed this technique mostly through trial and error. You 672 00:34:09,000 --> 00:34:10,520 Speaker 1: dip it in this, you dip it in that, you 673 00:34:10,680 --> 00:34:12,680 Speaker 1: did this temperature, then you cool it. You get a 674 00:34:12,719 --> 00:34:15,760 Speaker 1: really hard sword. It's definitely a slower way to make progress, 675 00:34:15,800 --> 00:34:18,880 Speaker 1: but it's possible. Isn't it possible that we need, you know, 676 00:34:18,960 --> 00:34:21,600 Speaker 1: a starfaring race of aliens that have been doing this 677 00:34:21,640 --> 00:34:24,080 Speaker 1: for a million years and sort of like stumbled their 678 00:34:24,120 --> 00:34:26,680 Speaker 1: way into a warp drive or you know, lights be 679 00:34:26,880 --> 00:34:29,719 Speaker 1: travel or something without having a deep understanding of it 680 00:34:29,760 --> 00:34:33,440 Speaker 1: that they could communicate to us. Yeah. Yeah, interesting. Nice. So, 681 00:34:33,560 --> 00:34:35,560 Speaker 1: like one way of kind of reading that scenarro is 682 00:34:35,560 --> 00:34:38,160 Speaker 1: that these aliens needn't be any more intelligent than us 683 00:34:38,280 --> 00:34:40,840 Speaker 1: or any kind of radically different to us. But they 684 00:34:40,880 --> 00:34:42,960 Speaker 1: could have just been around a lot longer, right, and 685 00:34:43,000 --> 00:34:44,600 Speaker 1: so they had more time to kind of do the 686 00:34:44,600 --> 00:34:47,120 Speaker 1: trial and error procedure and come up with some things, 687 00:34:47,120 --> 00:34:50,800 Speaker 1: but then some some great technologies and perhaps innovations that 688 00:34:50,960 --> 00:34:54,520 Speaker 1: kind of get them to other star systems or something 689 00:34:54,560 --> 00:34:56,719 Speaker 1: like that. But then they're not able to communicate to 690 00:34:56,800 --> 00:34:58,600 Speaker 1: us how they've done it because of because of how 691 00:34:58,600 --> 00:35:01,040 Speaker 1: they got there. Yeah, that that that's only seems pausible. 692 00:35:01,160 --> 00:35:03,040 Speaker 1: But then I guess it's like like we were saying 693 00:35:03,080 --> 00:35:05,719 Speaker 1: that that's different from this other worry, which is that 694 00:35:05,760 --> 00:35:08,520 Speaker 1: they've got there in kind of more of a theoretical ways, 695 00:35:08,560 --> 00:35:10,239 Speaker 1: that they do have something that we might want to 696 00:35:10,239 --> 00:35:13,719 Speaker 1: call understanding of the of the underlying physical theory that's 697 00:35:13,880 --> 00:35:16,799 Speaker 1: underpinning their technology, but but that it's just kind of 698 00:35:16,840 --> 00:35:19,359 Speaker 1: so so different, and again they're kind of carving up 699 00:35:19,360 --> 00:35:21,240 Speaker 1: and thinking about the world in a way so different 700 00:35:21,280 --> 00:35:23,120 Speaker 1: from how we think about it that they're not going 701 00:35:23,160 --> 00:35:25,920 Speaker 1: to be able to communicate their technologies and their their 702 00:35:25,960 --> 00:35:28,400 Speaker 1: insights to us. For that kind of reason, something that 703 00:35:28,440 --> 00:35:31,920 Speaker 1: I do wonder in in the kind of this vicinity 704 00:35:31,960 --> 00:35:35,120 Speaker 1: and more related to the latter scenario, where the worry 705 00:35:35,160 --> 00:35:37,239 Speaker 1: that these creatures might just be so radically different from 706 00:35:37,280 --> 00:35:39,160 Speaker 1: us that we just can't learn anything from them. So 707 00:35:39,400 --> 00:35:42,880 Speaker 1: to one source of optimism might just be that we 708 00:35:42,960 --> 00:35:45,960 Speaker 1: might think that the kind of counter as an agent 709 00:35:46,120 --> 00:35:48,319 Speaker 1: in the sense right where that's a very broad term, 710 00:35:48,360 --> 00:35:49,839 Speaker 1: but it's a kind of a bit of a philosophical 711 00:35:49,920 --> 00:35:52,480 Speaker 1: term of art, But you know, we're agents. We have 712 00:35:52,560 --> 00:35:55,040 Speaker 1: some sort of some sort of aims and goals and consciousness. 713 00:35:55,080 --> 00:35:57,120 Speaker 1: But to counter as an agent and to have these 714 00:35:57,160 --> 00:36:01,359 Speaker 1: sorts of interests in exploration and build technology, there might 715 00:36:01,400 --> 00:36:03,680 Speaker 1: have to be some sort of commonality to what it 716 00:36:03,760 --> 00:36:05,560 Speaker 1: is to be an agent, right, So to be that 717 00:36:05,800 --> 00:36:08,440 Speaker 1: highly evolved, to be pursuing those sorts of pursuits and 718 00:36:08,440 --> 00:36:11,040 Speaker 1: building those sorts of technologies, it might just kind of 719 00:36:11,080 --> 00:36:13,400 Speaker 1: be the case that they'd have to have something somewhat 720 00:36:13,400 --> 00:36:16,600 Speaker 1: in common with other agents, namely us, that we could 721 00:36:16,600 --> 00:36:19,440 Speaker 1: find at least some sort of common ground. And again 722 00:36:19,480 --> 00:36:22,000 Speaker 1: that's a little bit speculative and hopeful, but it's something 723 00:36:22,000 --> 00:36:26,359 Speaker 1: that I kind of and somewhat persuaded by sometimes, So yeah, 724 00:36:26,360 --> 00:36:28,480 Speaker 1: that that might be a cause for optimism. I think 725 00:36:28,520 --> 00:36:31,480 Speaker 1: that is an attractive argument, you know, to suggest like 726 00:36:31,920 --> 00:36:34,480 Speaker 1: in order to develop in the universe, you have to 727 00:36:34,480 --> 00:36:37,799 Speaker 1: be curious, and you have to build mental models to 728 00:36:37,880 --> 00:36:40,560 Speaker 1: explain why things happen in your life, and those mental 729 00:36:40,600 --> 00:36:45,279 Speaker 1: models naturally develop into you know, scientific thinking. I think 730 00:36:45,320 --> 00:36:47,719 Speaker 1: that's an attractive argument, but it also feels to me 731 00:36:47,840 --> 00:36:51,120 Speaker 1: a little bit too easy. You know. It's sort of 732 00:36:51,120 --> 00:36:53,200 Speaker 1: like the kind of argument you make where you say, like, well, 733 00:36:53,239 --> 00:36:56,080 Speaker 1: everybody drinks copy in the morning, because you know, everybody 734 00:36:56,080 --> 00:36:58,680 Speaker 1: wakes up and they're tired and copy helps, so therefore 735 00:36:58,760 --> 00:37:01,200 Speaker 1: all humans must drink of be right. It's sort of 736 00:37:01,239 --> 00:37:03,600 Speaker 1: like in the argument you make. I don't mean to 737 00:37:03,600 --> 00:37:05,719 Speaker 1: be too negative, but it's an argument from ignorance right 738 00:37:05,920 --> 00:37:09,520 Speaker 1: to say I can't imagine something different, therefore this must 739 00:37:09,520 --> 00:37:12,439 Speaker 1: be universal, where the whole reason we want to meet 740 00:37:12,440 --> 00:37:16,160 Speaker 1: aliens is precisely to confront those boxes and understand the 741 00:37:16,200 --> 00:37:18,960 Speaker 1: limits of our imagination. And so that's exactly the kind 742 00:37:19,000 --> 00:37:21,680 Speaker 1: of argument that I'm very tempted by, but I reject 743 00:37:21,960 --> 00:37:24,080 Speaker 1: for that reason that I want to push my way 744 00:37:24,120 --> 00:37:26,400 Speaker 1: out of it and understand if there are other ways 745 00:37:26,719 --> 00:37:29,640 Speaker 1: to explore this. But fundamentally, I think it's it's frustrating 746 00:37:29,719 --> 00:37:32,359 Speaker 1: because I don't think we can get out of that 747 00:37:32,400 --> 00:37:35,799 Speaker 1: box without meeting those aliens, the way people can't really 748 00:37:35,880 --> 00:37:39,280 Speaker 1: understand other cultures without doing some traveling or being exposed 749 00:37:39,280 --> 00:37:41,200 Speaker 1: to them, because sitting in your little village at home, 750 00:37:41,480 --> 00:37:44,920 Speaker 1: it's probably impossible to imagine other ways humans can be. Yeah, 751 00:37:44,960 --> 00:37:47,600 Speaker 1: that's right, that that that would be the best thing, 752 00:37:47,600 --> 00:37:49,920 Speaker 1: wouldn't it, if if we could meet these aliens. I mean, 753 00:37:50,320 --> 00:37:52,920 Speaker 1: I'm not like completely pessimistic that there are other ways 754 00:37:52,960 --> 00:37:54,719 Speaker 1: of doing it, Like, like we've touched on, I think 755 00:37:55,080 --> 00:38:00,480 Speaker 1: maybe maybe we could push ourselves really hard to kind 756 00:38:00,480 --> 00:38:02,680 Speaker 1: of think outside the box. I mean, something that comes 757 00:38:02,760 --> 00:38:04,879 Speaker 1: to mind. And no, I don't ask too many follow 758 00:38:04,960 --> 00:38:06,719 Speaker 1: ups on this, because I'm by far an expert on 759 00:38:06,800 --> 00:38:10,600 Speaker 1: the topic. But there's this new thing in physics constructor theory, 760 00:38:10,760 --> 00:38:12,640 Speaker 1: right which we're told is supposed to be a whole 761 00:38:12,680 --> 00:38:15,399 Speaker 1: new approach to the foundations of physics, which is nothing 762 00:38:15,440 --> 00:38:18,680 Speaker 1: like anything anyone has ever done or thought of doing 763 00:38:18,800 --> 00:38:21,279 Speaker 1: in terms of thinking about the universe before. And and 764 00:38:21,320 --> 00:38:23,680 Speaker 1: if if that's all it's cracked up to be, it 765 00:38:23,760 --> 00:38:25,839 Speaker 1: might be something along these lines right away of kind 766 00:38:25,840 --> 00:38:28,879 Speaker 1: of thinking from first principles in a completely different way. 767 00:38:29,080 --> 00:38:31,480 Speaker 1: If we think that there is the potential to really 768 00:38:31,480 --> 00:38:34,200 Speaker 1: shake up our foundation or thinking in these sorts of ways, 769 00:38:34,239 --> 00:38:36,480 Speaker 1: then then yeah, again, maybe we could have some optimism 770 00:38:36,560 --> 00:38:39,880 Speaker 1: that if there were this radically different species of aliens 771 00:38:39,920 --> 00:38:42,200 Speaker 1: that we came into contact with, that at first it 772 00:38:42,239 --> 00:38:44,719 Speaker 1: looked like we had no hope of interacting with them, 773 00:38:44,880 --> 00:38:48,440 Speaker 1: maybe after some work and some some reconceptualizing of our 774 00:38:48,480 --> 00:38:50,480 Speaker 1: foundations we could get there, right, And so I think 775 00:38:50,520 --> 00:38:53,279 Speaker 1: I think there might be some some reasons to be optimistic. 776 00:38:53,360 --> 00:38:57,560 Speaker 1: But but yeah, well, if the aliens do arrive and 777 00:38:57,560 --> 00:39:00,319 Speaker 1: they don't just like fry us from space, think we 778 00:39:00,320 --> 00:39:05,080 Speaker 1: should send the philosophers first or the physicists. I think 779 00:39:05,080 --> 00:39:07,880 Speaker 1: maybe the philosophers and the physicists should probably be working 780 00:39:07,880 --> 00:39:10,120 Speaker 1: in tandem on this one. I think they've probably got 781 00:39:10,280 --> 00:39:12,879 Speaker 1: strengths and weaknesses in this kind of situation that could 782 00:39:13,000 --> 00:39:17,719 Speaker 1: complement each other, So send a team of both. I 783 00:39:17,760 --> 00:39:20,680 Speaker 1: asked no Him Chamski if he thought that scientists would 784 00:39:20,680 --> 00:39:22,480 Speaker 1: be allowed to talk to the aliens, and he was 785 00:39:22,520 --> 00:39:26,400 Speaker 1: pretty cynical about whether military and political structures would allow 786 00:39:26,480 --> 00:39:30,600 Speaker 1: scientists and philosophers to speak on behalf of Earth, which 787 00:39:30,640 --> 00:39:33,040 Speaker 1: is a whole other reason to be pessimistic and not 788 00:39:33,160 --> 00:39:34,839 Speaker 1: a road I want to go down today. I think 789 00:39:34,880 --> 00:39:38,200 Speaker 1: another question people think about when they imagine speaking to 790 00:39:38,280 --> 00:39:41,560 Speaker 1: aliens is putting aside all these philosophical questions and say 791 00:39:41,560 --> 00:39:44,120 Speaker 1: they have similar structures, and they've thought about physics in 792 00:39:44,120 --> 00:39:46,320 Speaker 1: similar ways. They're just really far advanced from us. A 793 00:39:46,400 --> 00:39:50,200 Speaker 1: basic question is how could they teach us what they know? 794 00:39:50,360 --> 00:39:54,000 Speaker 1: How could we possibly understand the science of a super 795 00:39:54,080 --> 00:39:57,440 Speaker 1: advanced race. It's sort of like if you gave Galileo 796 00:39:57,800 --> 00:40:01,000 Speaker 1: a laptop, where would you even go to explain to 797 00:40:01,080 --> 00:40:03,040 Speaker 1: him how it works and what you would do with it. 798 00:40:03,200 --> 00:40:06,400 Speaker 1: People think about, like, you know, how to bootstrap humanity 799 00:40:06,520 --> 00:40:09,840 Speaker 1: up to the level of potential galactic aliens. Well, I 800 00:40:09,880 --> 00:40:12,400 Speaker 1: think they're be inclined to be a bit more optimistic, 801 00:40:12,800 --> 00:40:15,800 Speaker 1: maybe just from the kind of observation that we teach 802 00:40:15,880 --> 00:40:20,319 Speaker 1: children all sorts of complicated things, and I've seen many 803 00:40:20,440 --> 00:40:22,879 Speaker 1: child I mean, this is not necessarily a good thing, 804 00:40:22,920 --> 00:40:26,120 Speaker 1: but you see kids these days just taking to laptops 805 00:40:26,120 --> 00:40:28,400 Speaker 1: and iPads as if it was kind of innate in 806 00:40:28,440 --> 00:40:30,960 Speaker 1: them to use these objects, which strikes me as kind 807 00:40:30,960 --> 00:40:32,880 Speaker 1: of crazy, but then also makes me think, look, if 808 00:40:32,920 --> 00:40:35,799 Speaker 1: we can teach kids to use these strange new bits 809 00:40:35,840 --> 00:40:38,480 Speaker 1: of technology, and we can educate our children to do 810 00:40:38,520 --> 00:40:41,560 Speaker 1: all sorts of funky things like maths and logic and 811 00:40:41,800 --> 00:40:44,319 Speaker 1: art and poetry, then yeah, why couldn't the eight Why 812 00:40:44,320 --> 00:40:46,840 Speaker 1: couldn't we be the children of the aliens? Why couldn't 813 00:40:46,880 --> 00:40:50,480 Speaker 1: they take us under their wings and teach us their ways. 814 00:40:50,719 --> 00:40:53,040 Speaker 1: I have a little bit of optimism there, I think, Yeah, 815 00:40:53,120 --> 00:40:55,000 Speaker 1: let me take your optimism and turn it back into 816 00:40:55,000 --> 00:40:57,480 Speaker 1: a nightmare scenario, which seems to be my role in 817 00:40:57,480 --> 00:41:00,719 Speaker 1: this conversation, which is the aliens come and they have 818 00:41:00,800 --> 00:41:03,880 Speaker 1: super advanced science, and us this is this who have 819 00:41:03,960 --> 00:41:07,239 Speaker 1: grown up. We're thinking one way, can't rock it. But 820 00:41:07,520 --> 00:41:09,960 Speaker 1: we send our children to the alien schools and you're 821 00:41:09,960 --> 00:41:12,319 Speaker 1: write to them. It probably feels totally natural. Then there's 822 00:41:12,360 --> 00:41:15,279 Speaker 1: this generational divide where one set of humanity is like 823 00:41:15,440 --> 00:41:18,360 Speaker 1: super charged and thousands of years ahead of the old 824 00:41:18,400 --> 00:41:21,040 Speaker 1: ancient of gray haired folks like me who just never 825 00:41:21,120 --> 00:41:25,120 Speaker 1: really understand the modern world, right, and we've got something 826 00:41:25,160 --> 00:41:27,359 Speaker 1: of a toned down version of that. It feels like 827 00:41:27,480 --> 00:41:31,400 Speaker 1: today like the Internet natives, and that the technology native 828 00:41:31,719 --> 00:41:35,120 Speaker 1: people growing up do seem to be somewhat separated from 829 00:41:35,160 --> 00:41:37,920 Speaker 1: from the older generation. So yeah, it's it's conceivable that 830 00:41:37,920 --> 00:41:40,680 Speaker 1: that that sort of divide that we actually observe could 831 00:41:40,760 --> 00:41:44,319 Speaker 1: just be a lot more dramatic, right, Yes, that would 832 00:41:44,320 --> 00:41:46,439 Speaker 1: be That would be nightmarish for sure. So I guess 833 00:41:46,440 --> 00:41:49,799 Speaker 1: the answer is, don't give Galileo the laptop. Give Galileo's 834 00:41:49,920 --> 00:41:52,759 Speaker 1: kids the laptop, and they'll be playing a word all 835 00:41:52,840 --> 00:41:58,800 Speaker 1: within ten minutes. That's exactly alright, So then to wrap 836 00:41:58,800 --> 00:42:01,040 Speaker 1: it up, what do you think think is something we 837 00:42:01,080 --> 00:42:03,719 Speaker 1: can do to prepare? I mean, I don't know if 838 00:42:03,760 --> 00:42:05,600 Speaker 1: aliens are going to come. I don't know if aliens 839 00:42:05,640 --> 00:42:07,279 Speaker 1: even exist. I don't know if we will hear a 840 00:42:07,320 --> 00:42:10,640 Speaker 1: message from aliens. But these are deep and important questions 841 00:42:10,719 --> 00:42:13,160 Speaker 1: and we haven't really resolved any of them today. What 842 00:42:13,200 --> 00:42:15,400 Speaker 1: do you think are the most sort of important directions 843 00:42:15,440 --> 00:42:18,360 Speaker 1: for humanity or philosophy to sort of prepare for that 844 00:42:18,480 --> 00:42:20,480 Speaker 1: moment so that when it does happen, we have a 845 00:42:20,520 --> 00:42:24,960 Speaker 1: plan or a thoughtful structure in which to explore these questions. Yeah, 846 00:42:25,000 --> 00:42:27,279 Speaker 1: good question. I mean I think actually one thing we 847 00:42:27,280 --> 00:42:30,719 Speaker 1: could do to prepare for that scenario is to look 848 00:42:30,760 --> 00:42:34,600 Speaker 1: hard at the sorts of things we take for granted. Right, So, um, 849 00:42:34,640 --> 00:42:38,000 Speaker 1: I think scientists do this, but non scientists do this 850 00:42:38,040 --> 00:42:39,759 Speaker 1: as well. Of course, we go about the world and 851 00:42:39,760 --> 00:42:42,040 Speaker 1: we take all sorts of things for granted about the 852 00:42:42,120 --> 00:42:44,759 Speaker 1: nature of our reality. And really what this is is 853 00:42:44,760 --> 00:42:47,279 Speaker 1: it kind of a philosophical commitment that we have to 854 00:42:47,480 --> 00:42:52,160 Speaker 1: various assumptions and premises and background kind of structures ways 855 00:42:52,200 --> 00:42:55,200 Speaker 1: of thinking, but that we're not particularly aware of because 856 00:42:55,200 --> 00:42:57,480 Speaker 1: we don't scrutinize them. So perhaps we could do something 857 00:42:57,520 --> 00:42:59,520 Speaker 1: like that. We could think about what some of these 858 00:42:59,560 --> 00:43:02,560 Speaker 1: most based stick assumptions that we take for granted in 859 00:43:02,560 --> 00:43:05,560 Speaker 1: in science but also in everyday life, and see if 860 00:43:05,600 --> 00:43:08,440 Speaker 1: they could possibly be questioned, because look, these aliens might 861 00:43:08,480 --> 00:43:11,239 Speaker 1: have very different foundational assumptions to us, and so I 862 00:43:11,239 --> 00:43:15,200 Speaker 1: think engaging in this sort of exercise could maybe come 863 00:43:15,200 --> 00:43:18,160 Speaker 1: close to preparing us for this kind of encounter. Yeah, 864 00:43:18,160 --> 00:43:20,839 Speaker 1: I totally agree. It's like preparing your travel. You should 865 00:43:20,880 --> 00:43:23,160 Speaker 1: be asking yourself. I wonder if they do drink coffee 866 00:43:23,239 --> 00:43:25,520 Speaker 1: where I'm going, or you know, if they have a 867 00:43:25,560 --> 00:43:27,640 Speaker 1: totally different kind of toilet where you don't squat, or 868 00:43:27,640 --> 00:43:29,520 Speaker 1: you don't sit there, you don't stand, or who knows what. 869 00:43:29,640 --> 00:43:32,520 Speaker 1: Preparing your mind for the breath of possibilities. And for 870 00:43:32,560 --> 00:43:34,640 Speaker 1: me at least, I totally look forward to that day 871 00:43:34,640 --> 00:43:37,879 Speaker 1: when aliens blow our little minds and tell us how 872 00:43:37,920 --> 00:43:40,000 Speaker 1: there are other ways to think about the universe, to 873 00:43:40,080 --> 00:43:43,160 Speaker 1: explore the universe, even to ask questions. What questions are 874 00:43:43,200 --> 00:43:46,279 Speaker 1: they asking? You know, not just what answers do they have, 875 00:43:46,360 --> 00:43:49,800 Speaker 1: but what do they find strange and fascinating about the universe. 876 00:43:50,480 --> 00:43:52,080 Speaker 1: It seems to me like a lot of what we 877 00:43:52,160 --> 00:43:55,839 Speaker 1: think about as objective in science is driven by aesthetics. 878 00:43:56,080 --> 00:43:58,720 Speaker 1: A lot of the questions we're asking in theoretical particle 879 00:43:58,760 --> 00:44:02,040 Speaker 1: physics are driven by I like this looks weird, or 880 00:44:02,160 --> 00:44:05,239 Speaker 1: I think it would be prettier that other way. Even 881 00:44:05,239 --> 00:44:08,000 Speaker 1: the discovery of the Higgs boson came about because people 882 00:44:08,000 --> 00:44:10,360 Speaker 1: were thinking, this theory seems kind of ugly, and it 883 00:44:10,400 --> 00:44:12,960 Speaker 1: would be much prettier if we added this one other piece. 884 00:44:13,160 --> 00:44:15,520 Speaker 1: And so there's a lot of you know, aesthetics and 885 00:44:15,760 --> 00:44:19,920 Speaker 1: subjectivity and um, you know, personality in how we explore 886 00:44:19,920 --> 00:44:22,080 Speaker 1: the universe. And so I think you're right that we 887 00:44:22,120 --> 00:44:24,400 Speaker 1: need to look at that and put that under a 888 00:44:24,440 --> 00:44:27,239 Speaker 1: microscope and wonder whether there are other choices that could 889 00:44:27,239 --> 00:44:29,080 Speaker 1: have been made great. Yeah, So we could even spend 890 00:44:29,080 --> 00:44:31,120 Speaker 1: some time in some art calories thinking about why we 891 00:44:31,200 --> 00:44:32,840 Speaker 1: like what we like and dislike what we just like. 892 00:44:33,200 --> 00:44:35,319 Speaker 1: I'd very much agree with that. Yeah, that sounds very 893 00:44:35,360 --> 00:44:37,879 Speaker 1: sensible today. Yeah, And you know, as much as I'd 894 00:44:37,960 --> 00:44:40,400 Speaker 1: like to send artists on that first contingent also to 895 00:44:40,440 --> 00:44:42,600 Speaker 1: meet the aliens, I think it's almost impossible we will 896 00:44:42,680 --> 00:44:46,440 Speaker 1: ever understand alien art and I don't know if that 897 00:44:46,480 --> 00:44:49,240 Speaker 1: bodes well or not for alien philosophy and alien physics, 898 00:44:49,280 --> 00:44:52,160 Speaker 1: but I look forward to one day finding out all right. 899 00:44:52,239 --> 00:44:54,920 Speaker 1: Thanks very much Sam for joining us for this crazy 900 00:44:54,920 --> 00:44:58,640 Speaker 1: and wide ranging conversation on how aliens think about science 901 00:44:58,680 --> 00:45:01,200 Speaker 1: and whether we might ever be able to understand it. 902 00:45:01,320 --> 00:45:11,960 Speaker 1: Thank you, Daniel, that was really fascinating.
