accelerating expansion

[edpell]

If vacuum energy accelerates the expansion rate of the universe and that produces a larger universe with more vacuum energy to accelerate the expansion is there a positive feedback loop here? Does the expansion rate grow exponentially? Do we get another big bang? Is it a big bang in it's inflationary period? If it stops the same way our inflationary period stopped (unknown) will that be the birth of the next universe?

Are you thinking of the Big Rip idea?
