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.

  • A finger snap is incredibly fast, occurring in just 7 milliseconds, making it the fastest rotational acceleration in the human body, with peak speeds reaching 7,800 degrees per second—about three times faster than a professional baseball pitcher’s arm—thanks to the perfect balance of skin friction and compression.

    Not saying you’re wrong, just pointing out this is interesting.

    A baseball pitcher snapping his fingers is where it’s at.
