How the Universe Works: What Caused the Big Bang? - documentary

This documentary looks into what caused the big bang which if we turn back the cosmic clock we would see happened around 13.8 billion years ago. The big bang describes the state of the universe only a couple of femtosecond’s after time started which is a time so close to the beginning of time that it really pushes your perception about what a small amount of time can be. 2 Femtoseconds is around 2 millionths of a billionth of a second which is pretty hard to imagine. No matter how close to the beginning it troubles some scientists that the universe started from “nothing” and expanded into “nothing”. Knowledge about what caused the big bang and what it is expanding into is something that we are going to need to learn if we want to expand our knowledge about the cosmos.

In the documentary there is an interview with professor Michio Kaku who is one of the figureheads in the multiverse theory which says that that our universe is just one of an infinite number of universes. The multiverse theory may hold the answers as to how any why our universe formed which is probably going to be a large part of science in the future if evidence can be observed or simulated in quantum computers.
