I feel like we got quite a lot of mileage out of that question posed by a random internet user. Cheers Ash.


It is interesting though. If you have two objects of vastly different mass "bounce" off each other such that the mathematical motion of the larger body is less than the Planck length, has the larger body moved at all? How would it be possible for such a transfer of energy to happen? Maybe in this case the ground does behave like a perfectly rigid surface.
