| 0:00.0 | Because they're these big communities, you're almost like pushed to attach yourself to one of them and become a string theorist or become a loop quantum gravity person. |
| 0:09.5 | And I think that is unfortunate and you could say that we always operate in like a digital universe where if gravity is fundamentally classical, there needs to be a lot more noise in the |
| 0:22.0 | gravitational field in comparison to the quantum case. |
| 0:28.0 | Jonathan Oppenheim, a professor of physics at Oxford, centers his work on a new approach |
| 0:32.8 | for combining quantum principles with gravity,, sidestepping mainstream frameworks like |
| 0:38.0 | loop quantum gravity and string theory. His research instead focuses on the stochastic coupling |
| 0:42.8 | between gravity and quantum mechanics. This is one of the most dense of all the toe |
| 0:47.1 | podcasts in terms of informational content per minute, rivaling that of some of the Carl Fristin episodes. |
| 0:52.7 | Contrary to the ordinarily trodden path of quantum gravity, |
| 0:55.7 | which often dominate conversations on unifying quantum mechanics and general relativity, |
| 1:00.3 | Oppenheim introduces stochastic processes as a new axis for inquiry. What ramifications does this |
| 1:05.7 | have for prevailing theories? We explore that. Jonathan's expertise extends to quantum information, and he's done |
| 1:11.6 | plenty of work on the quantum version of thermodynamic laws, like the second law, and the |
| 1:16.4 | third law. Something not explored in this episode, but I can't seem to find it anywhere, |
| 1:20.9 | is the connection between the classical and the quantum by making an equivalence between |
| 1:24.9 | imaginary periodic time and finite temperature. |
| 1:28.3 | This is also known as analytic continuation, and is often just proposed as an unfysical mathematical |
| 1:33.0 | scheme rather than a profound connection between quantum field theory and statistical mechanics. |
| 1:38.3 | If anyone knows more about the bridge between these two, then please let me know. |
| 1:41.5 | At the end of this episode, there will be lengthy updates. |
| 1:44.1 | Always feel free to use the timestamps, which are in every single theories of everything episode, to jump to the sections that you're interested in most. Also, if you're interested in submitting a question for Jonathan when he comes on again, or any tow guest from this point forward, we're instituting a new system, you comment with the word query, then a colon, and then your question. This way, it's easy for me to parse through, okay, if I'm interviewing Jonathan again, I just look at the old Jonathan episode, Control F for the word query, and then I find all the questions and I can then submit them to Jonathan in the episode itself, crediting your username either in the description or orally. My name is Kurt Jai Mungle and I have a background in mathematical physics and I use that to analyze the various |
| 2:21.4 | theories of everything that are out there like string theory like Wolframs, like what's coming |
