Will electrons fly out of atoms and planets lose orbit?

  1. Sep 5, 2010 #1

    I'll take you've heard of the heat death of the universe.

    Now I was wondering: will electrons actually, at some point, leave their atom? If so, is this solely due to the fact that the quantum mechanical chance of an electron being out of an atom is not zero and thus, according to the frequentist's interpretation of chance, it must happen at some point?

    In that case, what about a classical system with a planet orbiting a much bigger planet in a stable orbit. Will the planet actually, at some point, leave this orbit? If so, why? (due to what sort of mechanism?) Must it happen?
