Roger Penrose believes in a model he calls Conformal Cyclic Cosmology. He doesn't believe in Cosmic Inflation, and instead proposes that the accelerating expansion of our present universe forms the inflationary period of the next universe. He gets around the second law of thermodynamics by saying that the difference between the two universes is a redefinition of entropy. The mapping between the two different definitions of entropy makes our maximal entropy state look like a minimal entropy state in the new universe.
