All you have to do is die.
If you wake up again somewhere else with full continuance, then the Universe has to be infinite, because the Boltzmann formation of your mind structure with all memories intact would have a chance of occurring such that you may as well call it infinite.
1/10^50^10^C
Where C is the complexity/continuation of your sense of self value. Whatever that valuation is. The rest is the Boltzmann probability, and I don't actually have the real number on hand, but it's a double exponent and looks about that big. So that's more of a round-a-bout example, not meant to be mathematically exact.
