inflationary universe

inflationary universe

n.
A cosmological model in which the early universe undergoes a period of exponentially rapid expansion, resulting in the high degree of homogeneity of matter observed in the present-day universe.

inflationary universe

n
(Astronomy) a variation of the cosmological big-bang theory in which the early stage of the evolution of the universe is postulated to include a period of accelerated expansion

A new inflationary universe scenario: a possible solution of the horizon, flatness, homogeneity, isotropy, and primordial monopole problems.
In particular, by using the correspondence between the de Sitter symmetry group in D-dimensions and the conformal group in an euclidean (D-1)-dimensional "boundary" space (Strominger, 2001), it is possible to calculate general important features of the system, such as the correlations functions of the fields that govern the dynamics of the inflationary Universe (Biagetti et al.

He predicts that, with the inflationary universe becoming more and more inescapable, coping with the infinities it requires will become the central problem in cosmology and physics going forward.

He notes that the necessity of a definite "edge of time" for any inflationary universe suggests creation by a transcendent cause.
They searched for circular variance patterns in simulations of the cosmic microwave background that assume the basic properties of the inflationary Universe, and all found circles that are very similar to the ones in the WMAP data.

Subsequent theories were to give birth to many variations of the Big Bang model and the process continues, producing, in turn, an inflationary universe, a chaotic universe, multiverses, an eternal universe, and so on.
However, an ever-increasing supply of satellite data now supports the theory of an inflationary universe.
