Did you pull that number out of a hat?* > *No. For the deviation to be unobservable by the Planck satellite, deviation from perfect flatness would have to be smaller than about 0.1%. If R is the radius of the observable universe and Rc is the minimum radius of the entire universe then (R/Rc)^2 < 0.001. Solving this inequality gives us Rc > 32R approximately. Since this is just a back of the envelope estimate and there are many uncertainties I used a factor of 100 to be conservative. Volume is proportional to the cube of that so there must be AT LEAST one million times more stuff in the entire universe than what we can see, or will ever be able to see. And there could be infinitely more stuff. * *>> If both the transition between non-existence and existence AND the > finite process called "inflation" started at T=0 and stopped at some > unknown time later then: * > *1) The entire universe is finite if and only if it was finite at T=0 * > *2) The entire universe is infinite if and only if it was infinite at T=0 * > > > * > I disagree that T=0 is a beginning time for an infinite universe, > which IMO has no beginning.* > *I could be wrong but I tend to agree that the universe, the entire universe, probably had no beginning. I say that because I think the Many Worlds theory is probably true, and because I think not just inflation but the particular type of inflation called Eternal Inflation <https://en.wikipedia.org/wiki/Eternal_inflation> is probably true. However it was you, not me who first introduced the term "T=0", and by definition that means time started then. And if you just decree that there couldn't be a T=0 if the universe is spatially infinite then, as I said before, you're assuming what you're trying to prove. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> atp > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
