Nothingness would no longer be the substance of the region outside the universe but rather nothingness would be contained within the region outside the universe.
But what of the boundary containing the nothingness? Such a boundary would simply be what it is which is found to exist outside the universe. In such a scenario, nothingness no longer is the antithesis of every thing but rather nothingness is a part of the whole, a part of whatever it is which composes the whole. In essence nothingness becomes an element of the whole. Nothingness becomes a part of the All. Nothingness, through the redefinition of every thing, now becomes a part of the thesis versus being the antithesis of the thesis.
One cannot find a void within the universe.
What one finds within the universe is, rather than a void, the void of a void. And what is the void of a void? The void of a void, being a double negation, appears to be something. But is it? Such a scenario would once again bring us back to Hegels process of thesis, antithesis, and synthesis with one slight twist. Now instead of:
Scenario I:
00000Thesis: 0000000something
00000Antithesis: 00000nothing
00000Synthesis: 00000?
We would have:
Scenario II:
00000Thesis: 0000000nothing
00000Antithesis: 00000something
00000Synthesis: 00000?
