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.

    I get your point but I’ll nitpick anyways:

    Isn’t satellites as much part of everyday life as submarine internet cables, and our lives would be radically different without satellites but having only submarine cables?

    Or do we need to see them to believe it?

      Hmmmm that’s a good point.

      I still wouldn’t count that as every day life because you’re not physically interacting with the satellite or submarine internet cables, even if you’re interacting with the effects of their existence.

      But now I have to justify why my stance of “being physically near but still unable to see or touch directly” (as an internal mechanism of something) is any more “everyday life”. It feels like an internal mechanism counts as just as every-day as the thing its a part of, but is it really?

      I don’t have a solid justification. It just feels different to me.
