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.


Interesting… how do you know about this?
Slow Mo Guys on YouTube have filmed glass cracking and calculated its speed many times. Very lovely channel that I recommend!
