Since spacetime bubbles with quantum fluctuation energy, and energy is equivalent to mass, and mass generates gravity, wouldn't spacetime be awashed with gravity?

Since it is random, it creates no inhomogeneities that attract one area to another.
But gravity, unlike em forces, doesn't cancel itself. It adds. So adding each point, whereby each point has energy in the form of quantum fluctuations, should give an infinite force.
Let us say that spacetime should be awash with gravity. What would you like to observe?
Gravitons perhaps? Gravitational waves perhaps?
I don't know about that, but the idea that space is filled with quantum fluctuations would lead to infinite gravity force, which is not observed. So what gives?
What if I said gravity was a psuedoforce, what would that say to you?
Not much.
And besides. Surely to have an infinite force, the universe needs to have expanded for atleast an infinite amount of time?
I don't see how you can deduce that. And I don't see how it resolves this paradox.
It is an awkward problem. So much so, it has a http://en.wikipedia.org/wiki/Vacuum_catastrophe" [Broken]

Space extends in every direction as far as we can see. Assuming the quantum fluctuations are uniform which direction would you expect the gravity to pull you?
If they are not uniform on a very large scale then we should be accelerating towards a region of higher density, us and the rest of the observable universe with us, in which case there would still be nothing to observe.
The only senerio where there would be observable effects would be if the fluctuations were ununiform on a scale we could observe. Very unlikely.
