Scientists speed up light, causing it to travel faster than "c," the long recognized speed of light in a vacuum. This, like the experiments conducted several years ago to briefly stop light, are hard for the average person to comprehend, but have important applications in fiberoptic communications.

Just how plausable is time travel? Could you go back in time and kill your own grandfather?. Would you want to? Time travel is a popular subject for films, but do the writers work out exactly what is happening? Current opinion seems to be that time travel is only possible to the future, and is only one way, by travelling at near light speed. However despite this, time machines seem to already be on sale.

Speed of light broken. But it may be awhile before we can harness it for anything useful. Fascinating, nonetheless.

Can the speed of light be broken? It's not 1 April, so this actually might be true. It'll be interesting to see the paper in Nature, if and when.
