The inflationary universe is a research area in cosmology focused on models in which the very early universe underwent a brief epoch of accelerated, quasi-exponential expansion driven by a high-energy ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted. Reading time 5 minutes Following the Big Bang, ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that very large question. Called SPHEREx, and set for launch on a SpaceX ...
