We know that the temperature 13.8 light years to your left and 13.8 light years to your right differ by less than one part in 100,000. The universe is only 13.8 billion years old so I don't see how they came to thermal equilibrium (or nearly so) if inflation didn't happen. > > *Penrose makes the point that there is no reason to suppose that the > initial state is not fractal -- grossly unsmooth on any scale, right down > to the smallest!* > If you examine a copper plate today its temperature does not display a fractal pattern, in fact I can't think of anything that does, so something certainly changed, if not inflation then what?. And if the early universe was as Penrose said the universe once was then I don't see how complex structures like you and me that are capable of making calculations could ever make an appearance.
