I find it prudent to point out (as the picture cannot) that the black space "outside" the grid-cone-thing of the universe isn't "empty space". It's nothing. This is a difficult concept to grasp. It's nothing. Not a vacuum. Not the interior of a bigger container. Nothing. Nada. Void. Empty. No light, heat, no up no down. No time. Nothing.
even nothing is something, since the concept of 'nothing' is a human construct, therefore it is something, as it is a construct in its own right.
its absolutely impossible to imagine nothing because the very fact you need to do something to achieve nothing means it is something.
