Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

Inflationary theory dates to the late 1970s and early 1980s, when physicists were trying to understand why the universe is so ...

Inflation, in the context of the big bang theory, refers to the episode of exponential expansion of the very early universe indicated by particle physics' Grand Unified Theories (Extensive references ...

Much as with your message on the expanding balloon, if the universe underwent the stupendous expansion proposed by the inflationary theory, then the tiny quantum jitters in the inflaton field ...

His 1981 paper heralded the virtues of inflation — an explanation for the smoothness, flatness and longevity of the Universe as well as the heat of the Big Bang — but it also challenged his ...

The widely accepted cosmological model begins with the Big Bang, followed by a rapid phase of inflationary expansion. This theory aligns well with observations of the cosmos such as the ...

Inflation was invented to explain a couple of features of the universe that are really hard to explain without it. The first is that Einstein’s general theory of relativity famously makes mass ...

His most recent work was an update to his paper titled A Smooth Exit from Eternal Inflation ... of a parallel universe could be detected. The biggest hurdle to testing his theory is one of ...
