We live in a Multiverse that contains an infinite number of universes

There are a variety of parallel universe theories out there – the inflationary bubble universe, the many-worlds theory, etc. They all presuppose that there is a larger multiverse that contains our universe and many others.

One type of parallel universe envisions countless bubble universes popping up and disappearing. This would mean that the beginning of our universe, the Big Bang, was just the creation of one bubble in a vast sea of inflating universes, which will eventually pop–or whatever universes do when their bubble juice becomes too unstable. Type 2 also includes the “brane” universe, which is an evolution of string theory.

One possible implication of parallel universes is the idea that there are an infinite copies of you in an infinite number of universes carrying out every possible version of existence.
