What do you mean “the energy of a baseball”? A baseball at what speed?
- moosedev 3y agoI assumed they meant a baseball at baseball speed.
- arethuza 3y agoRather than relativistic speeds, which would be bad: https://what-if.xkcd.com/1/ https://what-if.xkcd.com/1/
- mlyle 3y agoThey're saying a fastball pitch-- 340 joules or so of energy. The thing is, you need to be going implausibly fast to have a proton have a fastball level of energy. Even at .99999999 C, a hydrogen atom still has less than a microjoule of energy. You need a lot of 9's to get up to 340 joules. 1/sqrt(1-(0.99999999)^2) * (1 atomic mass unit * (speed of light)^2 1.05529895 × 10-6 joules
- idiotsecant 3y agoI feel like regardless of the exact speed of the baseball, that's somewhat more energy than a typical proton.
