What is half of infinity? It too is infinite.

How strange that infinity can have subsets of infinity. For example, counting by one, from one, numbers continue forever... but if you count only the odd numbers, it still goes on forever. If you count only prime numbers it goes on forever. If you try to divide a whole number into fractions, those fractions go on forever.

If you drew a circle that encompasses a value of ten, then drew a circle inside that represented all the odd numbers it would be half as big. If you draw a circle that represents all numbers, then drew a circle "inside" that represented the odd numbers, it would be just as big... if in fact one could draw an infinitely large circle.

Is infinity everything? Or is it nothing?

It's said that the universe, all dimensions, energy, space and time began from something infinitely small and is expanding into something infinitely large. Yet what we consider dimensional space is limited in size by the factor of time, in 14 billion years we estimate the boundary/edge of the universe at about 96 billion light years across, but is not expanding into anything, as everything is contained in the expanding sphere of that originally infinitely small pre-big bang.

Is there a difference between infinitely small and nothing?

Is nothing the ultimate infinity?

Is nothing actually something? Or vice versa?

Are there a finite number of infinite subsets?
