Kazanas (1980) called this phase of the early Universe "de Sitter's phase". The name "inflation" was given by Guth (1981) . ... Guth himself did not refer to work of Kazanas until he published a book on the subject, under the title The Inflationary Universe: The quest for a new theory of cosmic origin (1997), [ 59 ] where he apologizes for not ...
The history of the universe after inflation but before a time of about 1 second is largely unknown. [22] However, the universe is known to have been dominated by ultrarelativistic Standard Model particles, conventionally called radiation, by the time of neutrino decoupling at about 1 second. [23]
Vacuum state is a configuration of quantum fields representing a local minimum (but not necessarily a global minimum) of energy. Inflationary models propose that at approximately 10 −36 seconds after the Big Bang, vacuum state of the Universe was different from the one seen at the present time: the inflationary vacuum had a much higher energy density.
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 ...
The different variables are combined to form coordinates in the phase space and they are displayed using glyphs and coloured using another scalar variable. [ 1 ] A scatter plot , also called a scatterplot , scatter graph , scatter chart , scattergram , or scatter diagram , [ 2 ] is a type of plot or mathematical diagram using Cartesian ...
A link marked -indicates a negative relation where an increase in the causal variable leads, all else equal, to a decrease in the effect variable, or a decrease in the causal variable leads, all else equal, to an increase in the effect variable. A positive causal link can be said to lead to a change in the same direction, and an opposite link ...
Eternal inflation is a hypothetical inflationary universe model, which is itself an outgrowth or extension of the Big Bang theory.. According to eternal inflation, the inflationary phase of the universe's expansion lasts forever throughout most of the universe.
A directed graph. A classic form of state diagram for a finite automaton (FA) is a directed graph with the following elements (Q, Σ, Z, δ, q 0, F): [2] [3]. Vertices Q: a finite set of states, normally represented by circles and labeled with unique designator symbols or words written inside them
