What if dark matter and dark energy are the same and they (or it) continue to flood our universe, appearing from every point of the universe, and where it encounters matter it compresses it together with pressure increasing where there is more matter/mass (black holes etc), almost as if trying to expel it out of the universe?

This would explain the expansion, because dark matter=dark energy is "flooding" the universe driving it to accelerate in every direction and sees dark energy, dark matter as a type of a fluid.

Einstein himself did not view Gravity as a force of attraction. I think more outside of the "box" (that we are in, or limited perspective) thinking is needed when trying to unlock the mysteries of the universe
