Question

do Cherenkov radiation move ftl in water?
Answered by GPT 3.5
No, Cherenkov radiation does not travel faster than light in any medium, including water. Cherenkov radiation is produced when a charged particle moves through a medium faster than the speed of light in that medium, causing the emission of a characteristic blue light. However, the speed of light in water is still slower than the speed of light in a vacuum, so Cherenkov radiation in water does not travel faster than light.
