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.


The Mantis Shrimp is one of the few things that make me question pure raw evolution. How the fuck can you just evolve a sci fi plasma pistol?
