DAVID: Circles in the eye of the beholder. Many objections published. Supposes bumping other universes?-http://www.dailygalaxy.com/my_weblog/2012/06/image-of-the-day-evidence-of-a-past-univer...-Far more important, in my view, is the challenge Penrose throws down to the theory that the Big Bang was the beginning. Personally, I find the idea that our universe is part of a never-ending cyclical process far more convincing than that of God or chance creating it out of nothing. We come back to the suggestion that energy is the eternal "first cause". How that energy has behaved throughout past eternity, and what forms of material it has turned itself into, can only be a matter of unprovable speculation, regardless of bangs, strings and circles.
