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.
Sorry mate it will always be tough for me to hold and not troll internet strangers about that country’s dystopian deranged diseased state of things related to fire arms
