Good'ol Cherenkov radiation, it's such a nice hue of blue isn't it. Neutrinos are definitely odd little sub-atomic particles with "flavors" that may move faster than the speed-of-light according to the recent experiment(s) done by the OPERA team. Of course it's already been partially re-tested, basically looking for "extra"--you could say Cherenkov radiation, caused by the release of energy by these extra fast neutrinos. Specifically, they're looking for extra electrons (matter/anti-matter pairs, as I say below) being released which should eventually release a few anti-matter electrons in the process, called positrons--which when it happens the electron and positron would appear as a couple.

But, the Gran Sasso physicists involved in the re-testing of the OPERA team's experiment have yet to see even one event which is theorized to occur. This puts a very large noose on the OPERA teams finding, and makes it look more likely that what happened is a measurement error of some kind.

This has little to do with the video, but I thought I'd add it it in for the hell of it.
