I'd love to know who started this rumour as it is completely untrue...
Probabilities play a role in *observations* of the universe, but the universe itself is totally deterministic (as in our current understanding of the laws of phsyics show them to be completely deterministic)
Could you elaborate on this Cavediver? It would seem that if the universe was completely deterministic in fact, then the knowledge that it is deterministic would have been been the only knowledge that could have been arrived at. Which doesn't necessarily make it true - just knowledge which was unavoidable
