PBS Space Time Specials: Episode Guide & Ratings

In today's livestream you'll be able to Ask Matt O'Dowd, a PhD in astrophysics, anything. Tune in to ask your own question or see some of the great questions our audience has for Matt!

In this 90 minute conversation we explore what Theories of Everything really are outside the hype, dig into the essential physics mysteries that compel us to search for one, and survey the major TOE contenders currently being explored by the physics community.

The second in our two event series about Theories of Everything! Watch the first one: https://www.youtube.com/watch?v=_izoc... Please subscribe to Brian Keating's YouTube Channel to watch one-on-one interviews with the guest speakers and more: https://www.youtube.com/DrBrianKeating Existing Theories of Everything have not yet produced experimental evidence that solves the fundamental challenges facing physics. That lack of progress has opened up a sea of controversy, 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 Brian Keating, Lee Smolin, Sabine Hossenfelder, and Eric Weinstein for helping us create this great event.
