Alan Harvey Guth (/ ɡ uː θ /; born February 27, 1947) is an American theoretical physicist and cosmologist who is the Victor Weisskopf Professor of Physics at the Massachusetts Institute of Technology. Along with Alexei Starobinsky and Andrei Linde, he won the 2014 Kavli Prize "for pioneering the theory of cosmic inflation."
In 1980, Alan Guth realized that false vacuum decay in the early universe would solve the problem, leading him to propose a scalar-driven inflation. Starobinsky's and Guth's scenarios both predicted an initial de Sitter phase, differing only in mechanistic details.
The Inflationary Universe is a popular physics book by theoretical physicist Alan H. Guth, first published in 1997.The book explores the historical and theoretical development and expansion of the theory of inflation, which was first presented by the author in 1979 as the culmination of his research on the implications of theory of the Big Bang.
In physical cosmology, the graceful exit problem refers to an inherent flaw in the initial proposal of the inflationary universe theory proposed by Alan Guth in 1981. [1] In Guth’s model, the period of accelerated expansion (a.k.a. inflation) makes the universe homogeneous and flat but can never end. The problem with that model, later ...
He added that Alan Guth, one of the co-authors of the theorem, disagrees with Vilenkin and believes that the universe had no beginning. [ 10 ] [ 11 ] Vilenkin argues that the Carroll–Chen model constructed by Carroll and Jennie Chen, and supported by Guth, to elude the BGV theorem's conclusions persists to indicate a singularity in the ...
Alan Guth's 2007 paper, "Eternal inflation and its implications", [3] states that under reasonable assumptions "Although inflation is generically eternal into the future, it is not eternal into the past." Guth detailed what was known about the subject at the time, and demonstrated that eternal inflation was still considered the likely outcome ...
A pocket universe or bubble universe, also called pocket dimension, is a concept in inflationary theory, proposed by Alan Guth. Description It ...
The inflaton field is a hypothetical scalar field which is conjectured to have driven cosmic inflation in the very early universe. [1] [2] [3] The field, originally postulated by Alan Guth, [1] provides a mechanism by which a period of rapid expansion from 10 −35 to 10 −34 seconds after the initial expansion can be generated, forming a universe not inconsistent with observed spatial ...
