A field in a positive-energy false vacuum state could represent such a fluid, and the resulting repulsion would set the universe into exponential expansion. This inflation phase was originally proposed by Alan Guth in 1979 because the exponential expansion could dilute exotic relics, such as magnetic monopoles, that were predicted by grand ...
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.
The paradox was resolved, as Guth soon realized, by the inflation theory. Since inflation started with a far smaller amount of matter than the Big Bang had presupposed, an amount so small that all parts would have been in touch [vague] with each other. The universe then inflated, at a rate corresponding to a billion times the speed of light ...
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 ...
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 ...
Unit labor costs - the price of labor per single unit of output - increased at a 0.8% annualized rate last quarter, the Labor Department's Bureau of Labor Statistics said.
Core inflation climbed 0.6 percent on the month, doubling what economists anticipated. Both Republicans and… How inflation is fueling a nationwide labor movement
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 ...
