TL;DR: In this article, the authors discuss various alternative or heterodox theories in the period from about 1930 to 1980, among them the idea of a static universe and the conception that our universe evolves cyclically in infinite cosmic time.
Abstract: Since about 1970 the broadly accepted theory of the universe has been the standard hot big-bang model. However, there is and has always been alternative theories which challenge one or more features of the standard model or, more radically, question the scientific nature of cosmology. Is the universe governed by Einstein’s field equations? Is it really in a state of expansion? Did it begin with a big bang? The chapter discusses various alternative or heterodox theories in the period from about 1930 to 1980, among them the idea of a static universe and the conception that our universe evolves cyclically in infinite cosmic time. While some of these theories have been abandoned long ago, others still live on and are cultivated by a minority of cosmologists and other scientists.

TL;DR: The influence of Popper's ideas on cosmological thinking from about 1950 to 2020 has been discussed in this paper, where the authors cover both aspects, including his own views about cosmology including his dislike of the big-bang model, as well as the continual impact of his ideas.
Abstract: Twentieth-century cosmology and cosmogony only appeared sporadically in Karl Popper’s writings, and yet he was deeply interested in the subjects, which he commented on in lectures and articles. He followed the developments which during his lifetime resulted in a new picture of the universe, the hot big-bang theory, but remained sceptical with regard to the scientific status of cosmology. From the early 1950s to the present, Popper’s falsifiability criterion and related methodological rules have influenced physicists’ and astronomers’ discussion of cosmological theories, sometimes explicitly and at other times implicitly. Examples are the steady-state theory, inflation models, the multiverse hypothesis, and the controversy over cold dark matter. This chapter covers both aspects, Popper’s own views about cosmology, including his dislike of the big-bang model, as well as the continual impact of his ideas on cosmological thinking from about 1950 to 2020.
