Summary

Experimental evidence for any current Theory of Everything is, at best, inconclusive. This is perhaps the greatest fundamental challenges facing physics. That lack of progress has opened up a sea of controversy. Welcome to the second in our two-event series about Theories of Everything! Watch the first one: https://youtu.be/3MX8EpvLwao?sub_confirmation=1 Please subscribe to my YouTube Channel to watch one-on-one interviews with the guest speakers and more: https://www.youtube.com/DrBrianKeating?sub_confirmation=1 Please join my mailing list: http://briankeating.com/mailing_list.php to receive “conference proceedings” and other goodies from these events. From disagreements about the very necessity of TOEs, to questioning the cost/benefit of mega-billion dollar particle accelerators in search of them, to the emergence of competing TOEs from physicists outside of the academic community. In this 90 minute chat, we dive into the existential questions around TOEs. Special thanks to Matt O’Dowd, Lee Smolin, Sabine Hossenfelder, and Eric Weinstein for helping us create this great event.

0:00.0	Hello everyone. So this is the second in our very unusual two-part series here on space time.
0:07.0	Our great quest to understand the universe to find the mechanics of based reality and to understand why our universe exists at all seem to be at an impasse for the past century after the great revolutions of relativity and quantum mechanics.
0:22.0	So together with... relativity and quantum mechanics.
0:22.6	So together with Professor Brian Keating,
0:26.5	astrophysicist and friend,
0:28.2	we're joining forces to bring together
0:30.6	some of the leading researchers in particle physics and in cosmology to look for a way forward.
0:38.0	Brian, great to have you on space time again.
0:40.0	It's wonderful to be back with you and all of our esteemed guests. It's a real treat and
0:45.4	thrill for me. Last time we had an amazing lineup. We had Max Tegmark. We had James Beecham and Stephen Alexander and I think we really
0:55.8	started to converge on on some some useful thoughts. I really encourage you to go back and watch that. It's only 90 minutes long as we'll be today's.
1:06.0	But today our luminaries are no less luminous and I'm just going to give you a few words on each of the people we have here today.
1:16.5	My pleasure is to introduce Eric Weinstein, who is a very unique case holding a PhD in mathematical physics from Harvard but did not pursue the traditional
1:26.2	academic route at all. He's an author, a mathematician, an economist and managing director of Teal Capital.
1:33.0	And Eric practices physics outside the academic establishment.
1:38.0	In that regard, his most famous for his geometric community proposal.
1:42.0	And you can go to his podcast the portal and to the
1:47.6	portal wiki for the details on this radical new idea and the links to that will be in the
1:53.7	description. Sabina Hosenfelder is a theoretical physicist at the Franklin
1:57.9	Institute of Advanced Studies where she works extremely broadly but generally in quantum gravity research.
2:05.2	Sabina is also a prolific writer for popular media, a blogger and a
2:08.6	youtuber.
