Joe Rogan Experience #2554 – Carlo Rovelli

Why this one hits different

Carlo Rovelli is the rare theoretical physicist whose books sell like novels. In Joe Rogan Experience #2554 he joins Joe as his newest book, "On the Equality of All Things," hits shelves.

Who is Carlo Rovelli?

Rovelli is an Italian theoretical physicist best known as one of the founders of loop quantum gravity, an attempt to reconcile Einstein's general relativity with quantum mechanics by treating space itself as made of tiny, discrete pieces.

Outside physics departments he's famous for making impossibly big ideas feel readable. "Seven Brief Lessons on Physics" became an international bestseller, "The Order of Time" asked whether time as we experience it really exists at the level of fundamental physics, and "Helgoland" explored the strange relational picture of reality that quantum theory suggests.

Why it's worth your time

Joe has never been shy about asking the big questions (what time is, what reality is made of) and Rovelli is one of the few people who can take those questions seriously without drowning the listener in math. If you've ever wanted physics explained like a conversation at a bar, start here.
