Speed of light: How about this? Neutrinos are weird because they change their type. They start out as electron neutronos, say, and then oscillate to muon neutrinos and the other kind (I forget what they are). So the neutrino that is emitted isn't the same one that arrives at the detector. So nothing actually went faster than c.

Thank you, thank you. I am available to pick my medal in Oslo next year around April.

As for the speed of light thing, there was a report (linked to here on Blues, I think) about an experiment done... six, seven years ago or so, where they had two blocks of a particular material with a fiberoptic connection in between them.

They shot a lightbeam from one block to the other, and the beam had passed out of the receiving block before it was done exiting the first block, thereby going faster than the speed of light. It was a repeatable phenomenon.

Wish I could find that article again, but my google skills fail me today.
