Is it Quantum Mechanics Yet? (Score 1)

But the theory of computation still applies... there are some problems that will always be unsolvable via a computer, even if one can go arbitrarily far back in time arbitrarily many times. Whatever fancy computer you come up with, if it is a universal one (one that can emulate any other computer of its kind), I can just feed that same computer its own encoding, and some string, and no one (i.e. no computer) will be able to tell if that computer will ever stop running. In finite time.
