Atm the estimations shows that about 5% is visual matter, 27% dark matter and 68% is dark energy. That's a lot of "we have no idea".
Oh well, as I have read it dark matter is the reason things can move out and then retract.

But let's face it, your guess is as good as mine. And if a fish farts in an aquarium, that is also something we both have to consider as a legit input to the discussion.
