Steady-state cosmologies

: overview and development of disregarded models

Abstract

The current cosmological paradigm is the Hot Big Bang with the addition of dark matter and dark energy. This theory has evolved during the whole last century to become the most acceptable one. History has the tendency to forget. Indeed, several cosmological models have been abandoned and forgotten. The purpose of the present work is to recount the development of another family of cosmologies. The aim is to expound the diversity of the steady-state cosmologies and the evolution of the most famous of them, the Steady-State Theory. The chronological approach permits to show the different motivations leading to these models, their various interpretations and theit unexpected progression.
