Looking Beyond Inflationary Cosmology
In spite of the phenomenological successes of the inflationary universe scenario, the current realizations of inflation making use of scalar fields lead to serious conceptual problems which are reviewed in this lecture. String theory may provide an avenue towards addressing these problems. One particular approach to combining string theory and cosmology is String Gas Cosmology. The basic princi...
متن کاملComments on Inflationary Cosmology
In this talk we will discuss three different issues. First of all, there exist several proposals how to solve cosmological problems by adiabatic expansion of the Universe of a specific type, without any use of inflation. We explain why these models do not solve the flatness/entropy problem. On the other hand there exist some claims that inflation also does not solve the flatness problem. We sho...
متن کاملProspects of Inflationary Cosmology
In this review I briefly describe the evolution of the inflationary theory from the scenario based on the idea of supercooling and expansion in the false vacuum toward the theory of eternally expanding self-reproducing inflationary universe. I describe recent development of inflationary cosmology with Ω 6= 1, and then discuss some issues related to the possibility to verify inflation by compari...
متن کاملBasics of inflationary cosmology
The early stages of the universe evolution are discussed according to the hot big bang model and the grand unified theories. The shortcomings of big bang are summarized and their resolution by inflationary cosmology is sketched. Cosmological inflation, the subsequent oscillation and decay of the inflaton field, and the resulting reheating of the universe are studied in some detail. The density ...
متن کاملCosmology: Standard and Inflationary
In these lectures, I review the standard hot Big Bang cosmology, emphasizing its successes, its shortcomings, and its major challenges|developing a detailed understanding of the formation of structure in the universe and identifying the constituents of the ubiquitous dark matter. I then discuss the motivations for|and the fundamentals of|in ationary cosmology, particularly emphasizing the quant...
