This is the same idea that James Blish had as the foundation of "Cities In Flight" back in the 60's. He called it "Gnu-Gnap" some ancient word descrbing "begining from the end" and the universe contracted to a point where both the contracting antimatter universe, meets the expanding positive matter universe, resulting in a complete reset, rinse and repeat. It also sort of mirrors "Global Warming" story, one group swears tis is true, another swears that is true, and then the PR war starts.
