    infinite universes all with the same physical laws, but every unique possibility

    What makes different possibilities exist if the laws are the same? Is there a random function somewhere in the laws of physics?

      You can combine the same atoms into different larger elements. It’s like that. The same physical laws, but the combinations are infinite (or at least uncountable).

      The other concept is that the laws are different, but not true infinite combinations within reach.

      Or both.

        What combines the atoms differently when the laws of combining atoms are the same?

            The question is if the laws of physics are deterministic or not. If the rules are the same, then the result would be the same and all the universes in that case would be identifical.

            The multi universe theory assumes randomness, undeterministic physics or that every universe has different initial properties.

              Oh. You literally have no idea what these words mean. Got it.

      Different arrangements would do it, or you could think of it very loosely as the “if you made different decisions in each” kind of thing. Events/history is different, essentially.

      On your idea of a “random function” yes, pretty much everything at a fundamental level appears to be probabilistic to some level. Quantum theory cannot in most cases predict the exact outcome of an experiment, just the probability of different outcomes.
