WHat WhAt? Chaos is order... there is order in chaos... Thee energy of the world is constant, the entropy of the world endevors to increase...All the models discussed here start from the assumption that the usual rules of physics, including special relativity (SR) apply in any small region of the universe. This seems to be a pretty good approximation at least for our small region. Special relativity is important here because it tells us that we need to describe the universe in terms of 4-dimensional space-time. The geometric structure of the simplest space-times, those that are both homogeneous and isotropic, is described by the Robertson-Walker metric. The time evolutions of these space-times is given by a single scale parameter R which changes with time according to the Friedman equation
