This model seems to be plausible at all.

This does represent a very appealing theory - a cyclical process that looks much like a wave processing from node to node - no beginning and no ending - no awkward question about what came before, just wait long enough and the answers will all come to you (very Zen) :-) It is a pity that the big science research grants seem to follow the dramatic, spectacular route, and it would be nice to see more resources being applied to plan B and plan C.

Who completely understands dark energy?

Procrastination areas won`t take over, they will just shrivel away. The hot and cold regions of the CMB can be explained in quantum fluctuations of a Big Bounce. Science in China allows for hot and cold concepts in traditional Chinese medicine (TCM).

Sounds like another way to ignore infinity. The universe begins and ends over and over, or never began or ended, and has always existed?
