From John Butcher
Infinity does not have to defy imagination as Gefter suggests. It is sometimes possible to see the beginning and the end of an infinity at the same time, as in the infinity of the number of numbers between 1 and 2.
Now let us ask how many minuscule “pieces” make up a length of 1 metre. The answer is 6.19 × 1034 because that is how many Planck lengths (1.6 × 10-35 metres) would fit in it. It is my understanding that anything smaller than that does not physically exist.
Infinity exists only in maths, not in the real world.
