An outline of radiatively-driven cosmology

TL;DR

This paper proposes a radiatively-driven cosmological model where radiation influences early universe evolution, galaxy formation, and void creation, emphasizing radiation's role before gravity dominates.

Contribution

It introduces a comprehensive radiatively-driven framework for cosmology, detailing how radiation impacts structure formation prior to gravitational effects becoming dominant.

Findings

Globular clusters formed by radiatively-driven implosions

Galaxies formed by radiatively triggered gravitational collapse

Voids created by radiatively-driven expansion

Abstract

A Big Bang universe consisting, before recombination, of H, D, 3He, 4He, 6Li, and 7Li ions, electrons, photons, and massless neutrinos, at closure density, with a galaxy-size perturbation spectrum but no large-scale structure, will evolve into the universe as we now observe it. Evolution during the first billion years is controlled by radiation. Globular clusters are formed by radiatively-driven implosions, galaxies are formed by radiatively triggered gravitational collapse of systems of globular clusters, and voids are formed by radiatively-driven expansion. After this period the strong radiation sources are exhausted and the universe has expanded to the point where further evolution is determined by gravity and universal expansion.
