| 0:00.0 | What if the universe had turned out differently? Fred Adams pioneered the concept of what if |
| 0:04.5 | if you'd change gravity, electromagnetism, or the strength of the nuclear force. Would stars still form? |
| 0:11.7 | Could planets exist? Would atoms even exist? And ultimately, the most important question of all, |
| 0:16.8 | would we be here even to ask such questions? His work matters to you because it explains why our |
| 0:21.2 | universe seems so perfectly suited for life, and whether or not that's a lucky accident or maybe |
| 0:26.2 | points to something deeper. It gives scientific weight to the idea of the multiverse as well. |
| 0:31.3 | Not just science fiction, but as a serious cosmological possibility. It shows that the laws of nature |
| 0:35.7 | aren't just arbitrary. They might be constrained in surprising, elegant ways. |
| 0:40.3 | Fradden's doesn't just study the universe. |
| 0:42.3 | He studies all the universes that could have been, and that helps us understand why we're here at all. |
| 0:47.3 | The other kind of fine-tuning would be if you take a parameter and you just vary its value by a little bit, |
| 0:53.3 | then you get a universe or something that's very different. |
| 0:58.3 | Both of those fundamentally rely on the idea that if you change the constants a little bit, the universe doesn't work. |
| 1:04.2 | So I think, again, back to what we said earlier, the first step in the chain is to ask the more fundamental question, the starting question, what range of parameters work? Fred Adams, welcome all the way from Michigan by way of Pasadena. Welcome to back to San Diego. You've been here a few times and it's the first time sitting on the podcast. Actually, the second time sitting on the podcast. Oh, that's right. Yeah, that's true too. But that was like seven years ago. That's right. Everything before COVID is a mystery to me now. |
| 1:27.9 | Exactly. |
| 1:28.5 | Exactly. |
| 1:29.3 | Now, we'll get to the multiverse. |
| 1:30.5 | I think that's one of the most fascinating topics in all of science, you know, maybe concompt with the, you know, origin of life on other planets and our planet, et cetera, which you're involved with as well, or you've written about. And not only that, you've gotten into forays with past guests and very popular guest, Constantine Batesgen, working on Jupiter's, you know, size, a deep past. |
| 1:47.6 | That was a fascinating paper that we got to hear about. |
| 1:49.9 | But today you're here to talk about fine-tuning and all sorts of really cool things that are related to the multiverse. |
| 1:55.7 | But before we get there, we're speaking in early April. |
| 1:58.4 | It's after April Fool, so everything's okay. |
