To some, the world as we know it isn't what it appears to be, and everything that surrounds us could be just a simulation created by high-tech super computers and programmers from the future. NASA scientist Dr. Rich Terrile — a science and technical adviser for films like When Worlds Collide and TV shows such as Through the Wormhole — is one of those people. Head over to the source to check out Vice's interview with Dr. Terrile in which they discuss computing human lifetimes, simulations within simulations, and other mind-boggling theories.
