Dark energy should change over time.

If im right on dark matter and dark energy there should be changes over time in acceleration of the universes expansion.

If the knots in the large scale structure of the universe will eventually form A infinite cloud of quark like particles when they pool. then the dark matter is the stuff which does not fall in.  Dark energy is created from the compression of space - which must be stretched from somewhere. 

Idea goes this happened when our own matter as we know it formed from dark matter. Its happening again on a large scale - and will happen again on a larger scale.

The space between atoms and the particles that make them up is now controlled by forces and will not change.

The knots in the large scale structure  will eventually stop as well but the structures above will be speeding up as the matter pools and speed up falling in- they are stretching larger and larger areas of space. Some stretching is stopping some is speeding up.  If im right -it has to cause changes in the rate over time.
