Bight-ness: Your initial assumption, You cannot create something form nothing, contains the premiss that theres something here. In reality, its fairly well established that, in total, theres nothing here: no [net] electrical charge, no [total] momentum, and the total energy of the universe sums to zero. That is, to form something (say, S) from nothing (symbolized with zero, 0), then just separate zero into positive and negative components: 0 = S S.
I show some details in the first chapter of my (free) online book at
www.zenofzero.net; the zen of zero refers (in part) to the creation of the universe from nothing, presumably via some symmetry-breaking fluctuation in a total void. Of course, no one knows what the first symmetry breaker was; my guess is that it was either a string of (positive) energy or a particle.
I should admit, however, that questions remain about whether theres any [net] entropy in our universe. Certainly theres (positive) entropy on our positive side of reality", but the challenge is to define an appropriate entropy of space or the vacuum. At
http://www.advancedphysics.org/forum/showthread.php?t=6992 , Ive posed the question, submitted a very sketchy idea, and asked for comments from senior physicists, but so far, no takers.
