Cherenkov Radiation Credit: Wikipedia<\/p><\/div>\n

A recent criticism<\/a> of the apparently Faster-than-light (FTL) Neutrinos<\/a> inspiring a lot of discussion is the claim that if Neutrinos are going FTL – they must cause Cherenkov radiation<\/a>.<\/p>\n

Why? That doesn’t make sense. And its never been observed so how would anyone test that?<\/p>\n

Cherenkov Radiation Requires Charged Particles – But Neutrinos Have No Charge<\/u><\/p>\n

The beautiful blue-violet glow of Cherenkov Radiation<\/a> is only<\/span> caused by charged particles<\/a>, primarily electrons.<\/p>\n

But Neutr<\/span>inos are neutral, they have no charge. Furthermore, because they are fundamental particles; they don’t have any electrons.<\/p>\n

Commentary: Since Neutrinos have never been observed directly<\/u> making Cherenkov Radiation – why should anyone imagine they should?<\/p>\n

Yes, Neutrinos are commonly detected by observing Cherenkov Radiation, but indirectly – not directly. That extremely rare Cherenkov Radiation detection glow is not from a Neutrino – it comes from an Electron. It occurs in the extremely rare event of a Neutrino hitting an Electron head-on.<\/p>\n

This particular suggestion does not seem to hold water.<\/p>\n

However, you might want to read why Matt Strassler disagrees.<\/a> He bases this on the existence of a Neutrino non-zero magnetic moment. My response is that no Neutrino magnetic moment has ever been observed either; it is only postulated<\/a>.<\/p>\n

I do remain concerned that the OPERA experiment is only Detecting Only 1 Neutrino per Hour.<\/a><\/p>\n
