Alan Harvey Guth is an American theoretical physicist and cosmologist. . Guth realized from his theory that the reason the universe appears to be flat was that it was fantastically big, just the same way the. According to the inflationary universe scenario the universe in the very early stages of . The main idea of the inflationary universe scenario, suggested by Guth. The Inflationary Universe has ratings and 30 reviews. This is the compelling, first-hand account of Alan Guth’s paradigm-breaking discovery of the origins.

THE INFLATIONARY UNIVERSE
The standard model of hot big-bang cosmology requires initial conditions which are unjverse in two ways: These problems would disappear if, in its early history, the universe supercooled to temperatures 28 or more orders of magnitude below the critical temperature for some phase transition.
A huge expansion factor would then result from a period of exponential growth, and the entropy of the universe would be thd by a huge factor when the latent heat is released. Such a scenario is completely natural in the context of grand unified models of elementary-particle interactions.
In such models, the supercooling is also relevant to the problem of monopole suppression.
The Inflationary Universe: The Quest for a New Theory of Cosmic Origins
Unfortunately, the scenario seems to lead to some unacceptable consequences, so modifications must be sought. The editors of the Physical Review journals have curated a collection of landmark papers on General Relativity to celebrate its centennial.
The idea of inflation—an exponential expansion of the universe in its first moments—was published inin a paper that imported new ideas from particle physics into theoretical cosmology.
