“Physical reality does not require that we be pleased with its mechanism; we must see the implications of a theory for what they are and not for what we would like them to be.” -Kevin Michel
If you’ve been following along for a while — particularly in light of the recent BICEP2 results — you’re well aware that not only do we understand the history of the Universe all the way back to a hot, dense expanding state, but we’ve gotten a window into what happened before that: there was a period of Cosmic Inflation!
And while this was going on, there were places where inflation ended, giving rise to a Universe like our own, but other places where it didn’t, either giving rise to a Universe much later, or continuing to inflate exponentially until the present day. The consequences of this inevitably create what we know as a Multiverse.
But is that an explanation for why the fundamental constants of the Universe have the values that they do?
No. Not at all, in fact. The Multiverse is not the answer; go and find out why.
