The Low-Entropy Dawn: Running a Breathing Universe Back to the Beginning

The third of the Euler Cosmos sequence, and a continuation of A Point on the Helix of Time. Where the first paper extracts the one prediction the data can refute and the second follows the breathing universe to its end, this paper runs the same time-symmetric cosmology back to th...

The Euler Cosmos: A Phase-Space Breathing Universe

A single-sinusoid dark-energy density in e-folds defines a "breathing" cosmology and forces the equation-of-state boundary wₐ ≤ −3(1+w₀)². The parameters fixed by the expansion history over-determine the growth of structure, giving a zero-parameter go/no-go test falsifiable by Eu...
