I'm so out of touch with physics these days that I'm probably not even arm-chairing it correctly. But I still like to ponder crazy stuff... I'd put my money on a hypothesis that says causality is enforced whether we can perceive it or not. Say we had such a computer with FTL circuitry. You attempt to instruct the computer to halt the current program when an answer is received, thus preventing the inputs being supplied that would produce the given output. Our current time-based perception says "paradox" whereas this proposed hypothesis would say "the computer simply will not halt the program," not because it's designed with safeguards, but because the laws of physics maintain causality.
