Debate between cyclical and inflationary models continues from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
The ongoing debate between cyclical and inflationary models of the universe's origin and evolution remains a topic of intense discussion among cosmologists. Advocates of the cyclical model propose that the universe undergoes an endless cycle of expansion and contraction, with each cycle lasting billions of years. In contrast, supporters of the inflationary model argue that the universe experienced a rapid period of exponential expansion in its early stages, which explains its large-scale structure and uniformity. Proponents of the cyclical model point to the potential advantages it offers in addressing some of the key issues in cosmology, such as the origin of the universe and the nature of dark matter and dark energy. They suggest that each cycle of expansion and contraction could provide a natural explanation for the observed properties of the universe, including its large-scale structure and the distribution of galaxies. On the other hand, advocates of the inflationary model highlight the success of inflation in explaining the uniformity of the cosmic microwave background radiation an...
