[quote:ed49a]Einstein once said "The relativistic analogy can be carried to its logical end. Since time begins to slow down with higher speeds,it can be shown that at the speed of light it stops totally and beyond that begins to run backwards! Similarly, matter having contracted more and more, ultimately vanishes. But Beyond the spped of light it is difficult to imagine negative matter with infinite mass.

Einstein was probably right when he said that the speed of light was the upper limiting velocity in the universe."

There is a speed limit in physics, and it appears to be C...or at least we know of...
