If (1) we assume the universe has a finite size, and (2) we took a snapshot of the universe that includes particle speeds and locations, and (3) using perfect knowledge of science, would this be the perfect test of the existence of true randomness?
If true randomness existed, then using the data to simulate the future would fail tremendously because randomness can't be simulated.
If randomness did not exist, we could at least remove the possibility of one of the two free will concepts. We would also would disprove the existence of any divine entities.
Would this theoretically be the one experiment to solve every philosophical question? (Also for extra credit use Moore's law to make a formula to convert size of the universe to years we would need to wait to get a computer to have enough processing power. gl)
