I must admit that the details of how the fields are coupled went over my head, but I found the rest of the video quite accessible. Professor Copeland is a joy to listen to, and Brady asks great questions as usual.
I also learned that “inflation” and “the big bang” are not synonymous, and inflation occurred first.
Ever since I was a boy, I’ve been fascinated by astronomy and physics, have read a bunch of books - including Alan Guth’s “The Inflationary Universe” - and watched a ton of content, from “Cosmos” (as a boy when it first aired) to nearly every PBS Spacetime video (among other hard science YouTube channels).
This video is the first time I’ve ever come across the Oscillon, as well as the Truth Quark and Beauty Quark in another one of this channel’s videos, and at this point in my life, to be surprised by three whole new particles in one evening is kinda thrilling.
