John Moffat on Modified Gravity, Theories of Everything, and meeting Schrödinger
These interviews can be extremely technically dense at times but I'm not willing to sacrifice depth, nor my personal engrossment, for views.
The latter half of this video is primarily for posterity and I think you'll find it intriguiging only if you care about the history of physics around the time of Einstein, Dirac, and Feynman, which is why I put the answers to the more contemporary questions up front. John Moffat is an 88 year old luminary, which means there's a tendency to drone / ramble, since he doesn't perform much public speaking. But the content is there. Enjoy. - Curt
