Theory of eternal inflation summary

Webb24 juli 2024 · The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation. The partition function gives the amplitude of different geometries of the threshold surface in the no-boundary state. WebbInflation is generally thought of as an inordinate rise in the general level of prices. Four theories are commonly used to explain inflation. The first and oldest, the quantity theory, promoted in the 18th century by David Hume, assumes that prices will rise as the supply of money increases.

WebbEternal inflation begets a multiverse One of the more startling predictions of a variety of inflationary models is the existence of domains outside our observable horizon, where the fundamental constants of nature, and perhaps the effective laws of physics more generally, vary (Guth 1981; Guth and Weinberg 1983; Steinhardt 1983; Vilenkin 1983; WebbIn 2000, Raphael Bousso and Joseph Polchinski proposed using the regime of eternal inflation and transitions between many different vacua in string theory for solving the cosmological constant problem. At that time, no stable or metastable vacua of string theory were actually known. drugstore beetles in pantry https://loudandflashy.com
