Doesn't gravity stop this? Surely as the universe expands it does not cause Earth to occupy a greater volume?
Heck, even if this is true your arms would STILL be the same distance apart so far as you could tell. If everything expanded then so too would both your arms and the meter stick used to measure the distance between them.
It works as a thought experiment (more or less) but it wouldn't actually happen would it?
