62% Informative

If we could build a time machine, we could easily test whether alternate histories are created.

The multiverse is constantly being filled with every possible quantum possibility.

But traveling to the other universes wouldn't be easy, because they're far beyond our observable horizon.

We don't know how the alternate histories can accommodate changes in their space-time structures.

Paul received his PhD in Physics from the University of Illinois at Urbana-Champaign in 2011 .

He regularly appears on TV and podcasts, including "Ask a Spaceman " He is the author of two books, " Your Place in the Universe" and "How to Die in Space".
