The Universe in 90 minutes: Time, free will, God, & more | Sean Carroll

Posted by in categories: cosmology, neuroscience, quantum physics

Everything you ever wanted to know about parallel universes, time, entropy, free will and more, explained by physicist Sean Carroll.

Up next, Michio Kaku: The Universe in a nutshell (Full Presentation) ►

Do you have free will? Is our Universe the only one, or do we live in one of many? And what does Einstein’s theory of relativity really say about the nature of reality?

These are some of the big questions that theoretical physicist Sean Carroll tackles in this Big Think video.

In 2022, Carroll published The Biggest Ideas in the Universe: Space, Time, and Motion, a book that achieves that rare feat of detailing the inner workings of scientific concepts in a way that’s accessible but not overly simplistic.
