Uncertainty in quantum mechanics

There is no contradiction.

The experiments seem to have disproven local hidden variables, but not global hidden variables. So your omniscient universe is still in play.

A couple of questions about uncertainty principle–Why can’t one predict the effects of bouncing, say, a photon off of a particle? Is it that we don’t know all the necessary information about the photon to predict exactly how it would behave, much less how it wold interact with another particle? Or is it just virtually impossible to say what effect the photon would have, as even if we may predict the behaviour of the photon satisfactorily, it becomes unreasonably complicated to mathematically model the actual situation? Or something else entirely? Is it something that could be overcome through reasoning and/or increased capabilities of observation, or a logical absolute?

Thanks again for the replies.
