Universe Expansion ?

I just got a thought looking at the way light expand in a given space, what if the universe is no longer expanding but occupying empty space?

The acceleration momentum or the energy from the big bang has dissipated and Vacuum is the accelerating force were gravity is to weak to take hold. Like a bullet from a gun barrel is to far away to be affected by the vacuum of the barrel as the collapsing gases return to the low pressure bubble of the exploiting powder after it collapsed. An more important it help explain the acceleration of the universe.

The thought is out, let see what the community has to say.
