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.
Explain to us how we don’t interact with electrons in everyday life.
Yeah but electrons have no massI’m stupid, I was thinking of photons.
