I must admit to being somewhat amused that we have the existence of zero.
Example three apples in a jug of water, take three apples from the jug.
Sure you have zero apples but there is water where the apples were and air where the water was when it dropped.
So curiously before we even get as far as 1/0 is it ever possible that we even have zero?
This is especially significant when there is a measure of energy theoretically at every known point in the universe even in the most complete vacuum.
Just a thought, cheers
