No, I said "creation of spacetime". The distinction is important because "beginning" implies some sequential set of events, and those only happen within spacetime. Spacetime itself just is.Mike2 said:I think we are in agreement here. You say "beginning of spacetime".
It may be that an infinite universe can expand infinitely, remaining infinite all along. The point is that we just don't know. Scientists avoid infinities because they're difficult to deal with and because, historically, they've indicated problems in a theory. However, that doesn't mean they can't occur. A good scientist should be careful not to impose any such preconceived notions upon the universe. We've learned this lesson many times in the past.And we talk about "expansion". So doesn't that in and of itself imply that the universe cannot be infinite - that expansion would take forever to get to infinity?
That's right.So 60 e-folds is a scale factor of e^60?
