My guess is it is more likely inertia still propelling from the initial bang of creation whatever the cause.

Put a bowling ball in the middle of your bed. The bowling ball warps the matress just like a object warps space. The more massive the object the more it will warp space. Now place a tennis ball 1 foot away from the bowling ball. The tennis ball will roll towards the bowling ball because the bowling ball is more massive and warps the matress more. This is exactly how gravity works, it warps space.
Now many scientists say that the only thing that could be making the universe expand faster is gravity. But they can't locate or measure that gravity, only it's affects.
