01 / evaluation
“Big-brained creatures need an oxygen-rich atmosphere because oxygen is so potent for metabolism.”
02 / evaluation
“What plate tectonics does, because it fosters more vulcanism, is that you’re going to get carbon dioxide pumped into the atmosphere, which warms the planet up and gets you out of the snowball Earth phase.”
03 / recommendation
“Yeah. This is not to say that there was, so I was on Joe Rogan for exactly this paper, and I had to always emphasize, we’re not saying there was a Silurian, but we’re just saying that if there was, that’s why I love Gavin’s question.”
04 / belief
“You think about it, we’ve only been around, truly when we think about in Drake’s definition, you had to have radio telescopes, that’s been 100 years.”
05 / belief
“I think that there’s a problem with type one, which is that we already know about climate change.”
06 / belief
“Intelligent life and how long intelligent, technological civilizations, I think there’s a big question about how long those last.”
07 / belief
“I think the postmodernist on the left and the anti-establishment people on the right, and then just pseudoscience that kind of does this in-between thing.”
08 / belief
“I think maybe because we had the Judeo-Christian tradition where we already had this kind of God who was going to be the frame on which you could always point to that frame in the traditions that came from the classical philosophies of India and Asia.”
09 / belief
“If I could suddenly magically appear 100,000 years ago and talked to a hunter-gatherer about their worldview and their motivations, I might find something that, or no resemblance to things that I think are sort of, “Oh, that’s what naturally humans do.”
10 / uncertainty
“One of the funny things, I don’t know if they’ve gotten past this, but somebody calculated the problem with the Alcubierre drive or this warp drive was that if you dropped out of warp, there would be this spray of gamma rays that would sterilize any planet in front of you.”
11 / observation
“The only way maybe you could tell is by looking at the isotopic strata to see if there was anything reminiscent of an industrial civilization.”
12 / belief
“I mean, as long as you’re never trying to, “This is what experience is,” I think that’s kind of where you’re never going to have a causal account of experience just given.”
13 / observation
“The only way that we’re the only time that this whole process from abiogenesis to a civilization has occurred is if everyone one of those experiments failed.”
14 / observation
“Abiogenesis, glucose fermentation to propionic acid, all kinds of steps, all the way to homo sapiens, animal intelligence, land ecosystems, endoskeletons.”
15 / belief
“If you just, hey, the aforementioned cockroach with some bacteria, place it in Europa, I think you’d be surprised what happens.”
16 / belief
“Type two is 10 orders of magnitude larger than that, 10 to the 26th watts, and I think estimate for the galaxy is another 10 orders of magnitude.”
17 / belief
“The next term is the number of planets in the habitable zone, the place where we think life could form.”
18 / belief
“I mean, I think there is a hunger to acknowledge that there’s an elephant in the room, that we’re just removing the agent.”
19 / belief
“If we, normal humans saw 100 experiments, and we knew that at least one time there was a successful human civilization built we would say for sure, in 100 you’ll get another one.”
20 / commitment
“We’re going to have hard data finally that will, one way or the other … Even if we don’t find anything immediately, we will have gone through a number of planets.”
21 / belief
“The field has matured to the point where we can start asking about agnostic biosignatures, things that have nothing to do with earth’s history, but we think that would still be indications of this weirdness we call life.”
22 / belief
“Hot, reasonably far away from the star. I think JWST is really at the hairy edge of being able to do much with this.”
23 / belief
“Say 10 million years ago, we were really interested in this, in communicating with you youngins, but now we’re not at all.” And that’s just one of the beauties of this again, is how to think about this systematically because you’re so far past the hairy edge of our experience of what we know that you want to think about it.”
24 / belief
“I think you give a bunch of examples of that. Looking at temperature as a number is a very objective, scientific way of looking at that.”
25 / belief
“I think, again, if I were to bet everything, even in advanced civilizations are common.”
26 / belief
“The beginning of, I think the term is orogenesis, mountain building, the true Himalayan-style giant mountains, didn’t happen until this more robust form of plate tectonics, where the plates are really being driven around the planet.”
27 / belief
“I wonder who the dominant forces are in the world, because I think there’s a lot of people, the military they’ll probably move first so they can steal whatever advantage they can from this new discovery so they can hurt China or China hurt America.”
28 / belief
“Got to look, got to figure out ways to look. So, it’s not high on my list of things that I think are probable, but it certainly, it needs to be explored.”
29 / belief
“Just as a human society as we are now, we would engage and we would be detectable, I think.”
30 / evaluation
“You have to have the huge variety of resources that are always available on a planet somehow, even when it’s a super harsh condition. So that’s actually not a trivial experiment and if somebody did that experiment in the lab, I’d be a little bit skeptical because I could see bacteria doesn’t survive in this kind of temperature.”
31 / evaluation
“Everybody loves a good probability distribution, and they went a long way with this. But it turns out that the whole thing is flawed because, when you look at it, of course the timescale for the Sun’s evolution and the timescale for the evolution on life are coupled, because the timescale for evolution of the Earth is coupled, is about the same timescale as the evolution of the Sun.”
32 / evaluation
“It’s really just something we dreamed up to make the equation to do what we wanted them to do. So, it’s a nice fiction but really right now, we live in this weird moment in history of the great acceleration where the technology we used now is completely different from the technology we used 10 years ago is remarkably different from the technology from 100 years ago.”
33 / evaluation
“Okay, the Fermi paradox. I love talking about the Fermi paradox because there is no Fermi paradox.”
34 / evaluation
“Part of The Blind Spot is substituting a formal system, a calculus of data for actual experience that that’s more important. And so let me just do, before I go to those three responses, let’s just do the parable of temperature because I think people can… It’ll help them understand what we mean.”
35 / evaluation
“It’s a constellation of ideas that are all really sort of philosophical views. They’re not what science says, but because of the evolution of the history of science and culture got like pin the tail on the donkey, they were sort of pinned on and to tell us that this is what science says.”
36 / prediction
“So yeah, I think human beings being human beings, yes, there will be warfare and there will be conflict. And I don’t think it’ll be necessarily all that different because really I think within a few hundred years we will have lots of people in the solar system, and it doesn’t even have to be on Mars.”
37 / recommendation
“The idea that a bunch of astronomers who happen to have a radio telescope, Who Speaks for Earth, which I think was a great book somebody wrote. So, definitely we should be cautious, I would say, because we just have zero information.”
38 / evaluation
“Getting basic biology started, I don’t think is hard. It’s still wild, it’s an amazing process that actually I think requires some deep rethinking about how we conceptualize what life is and what life isn’t.”
39 / preference
“Some people in my field are. So I’m sorry folks, but what I really like is the idea of technosignatures because I think to me, SETI is the… First of all, intelligence.”
