A number of inflation model predictions have been confirmed by observation; for example temperature anisotropies observed by the COBE satellite in 1992 exhibit nearly scale-invariant spectra as predicted by the inflationary paradigm and WMAP results also show strong evidence for inflation. [4] However, some scientists dissent from this position.
Most inflationary models propose a scalar field called the inflaton field, with properties necessary for having (at least) two vacuum states. It is not known exactly when the inflationary epoch ended, but it is thought to have been between 10 −33 and 10 −32 seconds after the Big Bang. The rapid expansion of space meant that any potential ...
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.
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 ...
Starobinsky inflation is a modification of general relativity used to explain cosmological inflation. It was the first model to describe how the universe could have gone through an extremely rapid period of exponential expansion.
According to the inflationary model, the universe increased in size by a factor of more than 10 22, from a small and causally connected region in near equilibrium. [5] Inflation then expanded the universe rapidly, isolating nearby regions of spacetime by growing them beyond the limits of causal contact, effectively "locking in" the uniformity ...
The Atlanta Fed’s GDPNow model sees real GDP growth climbing at a 2.4% rate in Q4. Putting it all together The long-term outlook for the stock market remains favorable, bolstered by expectations ...
In 1982-1983, Steinhardt, Linde and Alexander Vilenkin realized that exponential expansion in the new inflation scenario, once it begins, continues without end in some parts of the universe. On the basis of this scenario, Linde proposed a model of a self-reproducing inflationary universe consisting of different parts. These parts are ...
