Why regress the expansion only back to the size of a peach.? Einstein, Hubble, Eddington, Hoyl, Wilson, Penzias, and many others regress back beyond the peach to ex nihlo universe. Then suddenly......the universe came to be.
Isn't that the truth of it?
They don't have a clue.
Given our means of understanding, something can't come from nothing, and yet it did.
Given our means of understanding, at least as I understand it, there is no way possible that any of us is here, and yet we are.
It is a miracle and a power and a gift so vast that we ought to quiver and rejoice every moment of every day.
