On a finite universe with no beginning or end
Last modified: October 2, 2007
Based on the conjecture that rather than the second law of thermodynamics inevitably be breached as matter approaches a big crunch or a black hole singularity, the order of events should reverse, a model of the universe that resolves a number of problems and paradoxes in cosmology is presented. A universe that has no beginning (and no need for one), no ending, but yet is finite, is without gravitational singularities, precludes time travel, in which events are neither determined by initial or final conditions, and problems such as why the universe has a low entropy past, or conditions at the big bang appear to be so "special", require no causal explanation, is the result. In connection to the model, the Friedmann-Lemaître-Robertson-Walker (FLRW) metric, the Schwarzschild metric, and the Penrose-Hawking singularity theorems, are discussed.
