Question: how often do you get hit by cosmic rays? x

Hey Maury I love your question. We are constantly being bombarded by cosmic rays from outer space. A lot of the time when they hit our atmosphere they cause massive particle showers that rain down on us as well. How often we get hit by cosmic rays depends on what their energy is. Reasonably high energy cosmic rays may hit us once per second! So if you were wearing the cosmic ray jacket you might light up every second!
