Time Travel Impossible, Say Scientists - Digg:
"news.discovery.com — By showing a single photon cannot travel faster than the speed of light, scientists prove time travel is impossible."
Really? Would this make it possible to focus a bit more on the only time we know for sure exists? Chronological time? Which has all the other times we might imagine within it, yet is relentless and moves forward inexorably regardless. We could travel within it much better than we do, enslaved by today's outmoded and generally lethal modes of transport.
