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: a possible solution to the horizon and flatness problem.
In cosmology, this issue becomes more apparent after the birth of the theory of inflationary Universe [1, 2] and successful in solving the horizon and flatness problems and eventually quantifying the seeds in terms of the density fluctuations for large scale structure formation and inhomogeneity for the microwave background radiation.

Inflationary Universe Model as the Origin of Big Bang Expectations for observational proof ...
It's telling us that things aren't just a little wrong, but terribly wrong." 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.
