I don't think accelerating expansion and brane bouncing are mutually exclusive. Earlier, when you said "bounce" I though you meant the old idea claiming that the universe will contract into a singularity and bounce back in a bang.

I used "bounce" as branes colliding.......It could have been Pop. Sci. I read Sci. Am. too; so I could have mixed the articles up.
I still think the Universe may be cyclic... but with The Big Crunch...back to a singularity....but Brane theory just seems closer to what's really happening.....and just "feels" right for some reason... and it explains why gravity "appears" so relatively weak compared to the other forces, IMO.
I was thinking along the lines that the accelerating expansion would nullify "bouncing"; but it may actually be a part of what causes Branes to "touch" and Bounce.
