The logic of this escapes me. Let's take one bit at a time.

"This will continue until the speed of the cluster can no more increase. So the expansion stops."

This seems to say that when acceleration stops, everything stands still. What stops it?

"That state is a potential state where the speeds of the clusters are very high"

This seems to contradict the first bit - things are still on the move.

"So the system starts contracting"

Did everything stop, then start again in the opposite direction?

There never was nothing.
