    define atmosphere or define an arbitrary line of Xkm above the average surface of earth.

    100km. Atmosphere is a gradient so yes it’s entirely arbitrary.

      If a person fell into the singularity of a black hole that had particles from our atmosphere, are we back to on earth again? (My vote is “s/he dead and no even if not”, but I think it’s interesting to think about).
