Where Do Space, Time and Gravity Come From? | Quanta Magazine
Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.
Absolutely engrossing podcast transcript which discusses emergent theories on the origin of space time and some recent research in quantum gravity. Sean Carroll is great as always.
I loved the ending which touched a bit on the philosophy of science:
“Well, I do think that and, you know, I think that there’s a school of thought that says that scientists should not talk about their results until they’re completely established and refereed and everyone agrees they’re right. And not only do I think that that’s implausible, because even results that are refereed and published could be wrong, I think it’s very antithetical to the spirit of how science is, you know, and I want to emphasize that science is not just a set of results that are handed down from on high, it’s a process. We could be wrong. We’re making suppositions and hypotheses and guesses, and we’re going to figure out whether or not they work. And that’s not a bug, it’s a feature. That’s, that’s how science works. So I’m very willing to talk about tentative things as long as I try to emphasize that they are tentative things.”Posted on 2022-05-07T11:02:17+0000
