The cosmological equations that so beautifully describe our universe make an uncomfortable prediction: interpreting them in the most straightforward way, they tell us that the universe may be infinite. Or not; it could turn out that the universe contains enough matter and energy to close in on itself and be finite, or perhaps the simplest interpretation of the cosmological equations is TOO simple. But according to our best theoretical understanding, an infinite universe seems at least possible - and some would say likely. If so this raises an even more crazy possibility. An infinite universe may literally contain every possible thing allowable by the laws of physics - each in infinite multitude. And that includes infinite versions of you. Today I’m going to try to convince THIS version of the reality of all of the others.
