See “Cherenkov Radiation”. High speed particles regularly enter the earths atmosphere at superluminal speeds. That is, they exceed the speed of light in that particular medium. This experiment seems to show superluminal speeds in a vacuum. Bad boys, breaking the law.. Would be a huge finding if duplicated, although I suspect an explanation will be found that does not upset Einstein.
The experiment was NOT done in a vacuum. From the end of the article:
“To reach Gran Sasso, the neutrinos pushed out from a special installation at CERN - also home to the Large Hadron Collider probing the origins of the universe - have to pass through water, air and rock.”
So, what’s the big deal? Am I missing something?
