Universe and countless others already exist under my theory.
The universe we know is like a ball. This ball is constantly expanding to the point where light reduces (Radiant flux) to scatters of individual photons. If lets say this ball (the universe) became so big from light that it would 'rip holes' in all known and unknown laws to man. In this ball because as you know the universe is expanding and the distance between each cluster of galaxies is getting greater due to light as mentioned above, it would rip every atom apart. Somehow if this were to happen to time and reality this could unlock different dimensions, different laws.. causing an infinite amount of possible outcomes (based on your perception of 'randomness').
Lets say in one-hundred-trillion-trillion-trillion years we may become Gods, ponies, you name it. At least in death you have the uncertainty to enjoy about your possible revival.
Don't argue this with me because their would be no point beyond the ideal assumption that I am wrong and that infinite is finite and that random is consequence.
