They wouldn't always have been so distant and what has communication got to do with looking the same?His first target was eternal inflation. Proposed by Alan Guth of the Massachusetts Institute of Technology in 1981, inflation says that in the few slivers of a second after the big bang, the universe doubled in size thousands of times before settling into the calmer expansion we see today. This helped to explain why parts of the universe so distant that they could never have communicated with each other look the same.
Why is that?It turns out that the constant has a lower limit that prevents inflation in both time directions. "It can't possibly be eternal in the past," says Vilenkin. "There must be some kind of boundary."
I thought that disorder only increased with an expanding universe, when time moves forward. I thought that when it contracted again as it would with a cyclic universe, disorder decreased.Cyclic universes have an "irresistible poetic charm and bring to mind the Phoenix", says Vilenkin, quoting Georges Lemaître, an astronomer who died in 1966. Yet when he looked at what this would mean for the universe's disorder, again the figures didn't add up.
Disorder increases with time. So following each cycle, the universe must get more and more disordered. But if there has already been an infinite number of cycles, the universe we inhabit now should be in a state of maximum disorder. Such a universe would be uniformly lukewarm and featureless, and definitely lacking such complicated beings as stars, planets and physicists - nothing like the one we see around us.
