I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.


I’ll just go with the correct answer: Cosmic rays.
Cosmic rays have mass?
Yes.
They sure do, and they’re randomly flipping bits in your computer’s memory once in a while.
Nooooo, dont do that, I’m busy speed running Mario64
