DAVID: Big Rip vs. Big Freeze:-http://phys.org/news/2015-06-cosmic-stickiness-favors-big-rip.html-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.-Dhw: 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? -DAVID: No. You forget that space may be concave or convex or flat. Every evidence for the past 50 years says flat, we get either rip or cold, unless the evidence has a drastic change, which I do not expect.-Yea verily, the voice of him that crieth in the wilderness... I prophesy that in 100 years current beliefs will be laughed at, but you know I'm wrong because other beliefs would contradict current beliefs. Yep. But I'm mightily impressed by your grasp of what will happen in 22 billion years, or 100 trillion years. I'd like to perfect my own theory about what will happen in 100 quadrillion years, so can I please rely on your support for my grant application?
