what if there is not enough mass to collapse the universe back on itself?(as it looks like) What causes the contraction of the universe?

What if space is not linear? There are some theories out there that it is not. Eventually there would be enough gravitational interaction to pull material back together.
What causes the contraction of the universe?
I believe in the end plain old gravity.

I think that is still one of the open questions.
The current line is that there is not enough mass and the universe is expanding and accelerating in its expansion.
But then we have the mysterious dark matter and dark energy.
>>>>>> Only about 4% of the total energy density in the universe (as inferred from gravitational effects) can be seen directly. About 22% is thought to be composed of dark matter. The remaining 74% is thought to consist of dark energy, an even stranger component, distributed diffusely in space <<<<<<<
Give them time and perhaps the accounting will reverse itself.
There is a recent article claiming that the Milky Way galaxy is much bigger than previously supposed.
