DAVID: Big Rip vs. Big Freeze:-http://phys.org/news/2015-06-cosmic-stickiness-favors-big-rip.html-QUOTE: "One scenario, dubbed the "Big Freeze," predicts that after 100 trillion years or so the universe will have grown so vast that the supplies of gas will become too thin for stars to form. As a result, existing stars will gradually burn out, leaving only black holes which, in turn, slowly evaporate away as space itself gets colder and colder.-"An even more radical scenario is the "Big Rip." It is predicated on a type of "phantom" dark energy that gets stronger over time. In this case, the expansion rate of the universe becomes so great that in 22 billion years or so material objects begin to fall apart and individual atoms disassemble themselves into unbound elementary particles and radiation."

DAVID: Comment: This article anticipates a definite end, nothing cyclical. It describes a universe that has a definite beginning and a definite end. This means a new universe will have to have a new creation.-Great balls of fire, folks, I predict that in just 100 years' time there will be what we experts call the “Big Oops”. Someone will realize that there have been some almighty blunders in current calculations and observations, and the universe is just going to go on doing what it's always done - pumping things out, sucking things in, building and demolishing for ever and ever, amen. Please can I have a grant?
