Battle of the Big Bang

About 13.8 billion years ago, the Universe burst forth from an infinitely dense inferno, started to expand and cool, and is still expanding to this day. The Big Bang is “science's earliest memory”, as authors Niayesh Afshordi and Phil Halper point out in this new book, so it's natural to ask what happened before it. But you may have been told that this is a daft question, because if time began at the Big Bang, then there can be no ‘before’. Battle of the Big Bang is here to debunk this myth and guide the reader between public perception and what cosmologists believe today.
