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.
Not so long ago I would have said electrons in a CRT screen (old school TV). When the electrons leave the accelerating anode, they are traveling at a reasonable fraction of the speed of light
I think that “with some mass” wasn’t meant literally but figuratively, specifically to exclude things like shooting subatomic particles.
I think OP means the kinda of things humans interact with and are able to perceive in their every day life.
Yeah but electrons have no massI’m stupid, I was thinking of photons.
