Zero and one are circumference and diameter.
This is why we have particles and forces (two identifiers), bosons and fermions, etc.
So, obviously, we have to figure out where the number ‘two’ originates. Not so difficult to figure out. It has to be a circle (any X and Y articulate a circle) (an imaginary line is both diameter and circumference of a circle) (abstract and concrete articulate a circle).
Thus quantum foam is, easily, a (hidden) circle. (Hidden-showing, abstract- concrete, any pair articulate a circle.)
You get this. Easily.
