In particular, there is neither a big bang nor a big crunch. The action is a higher derivative modification of Einstein's theory constructed in analogy to how the action for point particle motion in special relativity is obtained from Newtonian mechanics.11 pages, 2 figures (available from the author), uses phyzzxGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - TheoryA Nonsingular Universetext
