Out of the Blue

It is now officially fall here in the northern hemisphere, as the autumnal equinox occurred at around 5:05 am EDT today. I prepared for the occasion by shaving my summer beard yesterday, and my plan is to now let it grow out through the first day of spring. Last year I grew a beard from December until spring, and it ended up pretty epic, so I expect this to be pretty extreme.

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.

The thing is: Considering the time between the emission and the observation of the neutrino they calculated a speed greater than the speed of light - that means even if they're not the same neutrinos and there was a reaction somewhere in between they still had to be ftl to make such a measurement.

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.

I don't know of the experiment you mean (or maybe I read about it and forgot, who knows...) but could it have been something about this?

If yes then it can be explained through the tunnel effect.
