Light Speed

Lightspeed is a fun little shareware game that I stumbled across today. It's one of those "bounce stuff off mirrors to light up stuff" puzzle games, but with nice graphics, and additional features like a level editor and such. Warning: windows only download, shareware fee to unlock many levels and features.

Anyone got the time?

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.

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.
