Well, I wont claim to know any better, but I would have thought that if gravity was still there, however 'weak', the particles would slowly start to pull together again; unless something was actually exerting force on them( stronger than the gravity ), keeping them apart.

Anyway, if indeed the expansion is speeding up, that means energy is being continusly applied to the mass in the universe( thus providing the speed increase). Since energy = mass ( right? ), that means further that the amount of mass in the universe is increasing as well? And since all mass has gravity, as far as we know, that also means gravity increases? Thus eventually becoming strong enough to counter whatever other force is pulling the stuff apart...?

My non-existing education got cut short, so I'm a little out of the loop. Please correct me if something's wrong with my understanding.

Also, wont the whole 'expansion speeding up' thing also mean the entire mass of the universe will be traveling at light-speed in a 'few years'?
