To express CCC mathematically we need a formulation of Einstein's equations extending over the crossover joining each aeon to the next, governed by the requirement of ultimately massless material and a cosmological constant with a fixed positive value. This entails the introduction of a self-coupled conformally invariant massless scalar field carrying no physical degrees of freedom prior to crossover, but which emerges following the subsequent big bang as an actual (“dark”) initial material, rest-mass reappearing in the early stages. The evolution is governed by entirely classical equations, in contrast with the conventional view that quantum fluctuations are responsible for primordial irregularities in our early universe. Events involving super-massive black holes in the aeon previous to ours have observational implications.
