From Here to Infinity

One of the most fascinating and mind-bending topics to discuss is that of our own reality and the notion that the way we experience our Universe may not be the only version of events out there. If the number of Universes is truly infinite, and the many-world interpretation of quantum mechanics is true, are there parallel Universes out there, where everything in it evolved exactly the same way as our own, except for one slightly quantum outcome is different? Are there other Universes with slightly different versions of ourselves? Or let’s ask it this way: is it possible that there’s a Universe where everything happened exactly as it did in this one, but you made a single choice that had your life turn out as completely differently as a result? Where you took that trip, quit that job, kissed that girl, went to that school? Then there is the idea that there is a Universe out there where everything with a non-zero probability of having happened is actually the reality—but there are a lot of steps to get there.

The inflationary state, for example, must have happened for not just a long amount of time, but for an infinite amount of time.
