One can relate the expansion to negative and positive gravity, out of exactly positive and negative vacuum?

If one takes the zero quantity to extremes, even in mathematical terms?..for instance the ten plus one (10+1) numbers that equate to ten plus 1(zero) dimensions:10,9,8,7,6,5,4,3,2,1 ,0

now mathematically we can relate the numbers to positive and negative, or to the number theory relating to specifically "odd or even". Thus when one folows :

10-even-9-odd-8-even......

I realized this morning that the eternal accelerating expansion at the end of time is always occurring in the vacuum. The same eternal expansion that causes a big rip type of future also causes the eternal expansion of the big bang, and it presently causes light to propagate. If it was possible to introduce two opposite particles into the perfectly flat zero vacuum/singularity at the end of time the expansion of space would instantly rip them apart internally, an annihilation identical to what...

Nice Article. Vilenkin seems to have one of the better imaginative minds in physics. If large-scale topology is flat as WMAP indicated, then it has always been flat, which means the singularity of the big bang was/is infinitely extended. So there must be an infinite set of O-regions. I felt this was inevitable in the 60's when I first learned the big bang theory. And Vilenkin is right to question the breadth of possibilities. It is easy to conclude there are infinite many O-regions, the big...
