I was not looking for anything too technical, just trying to clarify your statement:
In other words, our physical universe came from nothing '0' and is expanding into everything 'O'--from zero to infinity--Omni-presence.

If zero does not = infinity, then in moving from 0 to infinity the Universe would change from finite to infinite.

If 0 = Inf. this change would be necessary only if there were a finite intermediate stage.
There never was nothing.
