Pushing the Limits of Physics Exceeding the speed of light opens one up to all kinds of theoretical problems, but two Austrian researchers claim there's no reason we can't build a computer that processes information at superluminal speeds. From Popular Science:
How fast is too fast? According to the laws of physics, the speed of light is a good boundary, as going beyond it opens you up to all sorts of paradoxes and space-time phenomena that are usually the stuff of sci-fi. But a couple of researchers in Austria have come up with a way to compute information faster than the speed of light.
