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.
Planes are a good answer. Commercial jets normally fly at about 900km/h.
Also satellites. Something in low earth orbit like the ISS or a starlink node would be going about 8km per second.
Are planes part of your daily life?
I use planes maybe once every thee years.
They’re everywhere all the time. Thousands of flights per day carrying millions of people.
I haven’t flown in several years, but in some years have taken 100+ flights.
For someone on the US coasts (especially North East) getting anywhere quickly beyond a couple hundred miles will possibly involve a plane.
I rarely use planes, but I usually see them flying overhead multiple times a day.
