Space Ripples Reveal Big Bang’s Smoking Gun

One night late in 1979, an itinerant young physicist named Alan Guth, with a new son and a year’s appointment at Stanford, stayed up late with his notebook and equations, venturing far beyond the world of known physics.

He was trying to understand why there was no trace of some exotic particles that should have been created in the Big Bang. Instead he discovered what might have made the universe bang to begin with.

Alan Guth was one of the first physicists to hypothesize the existence of inflation

The Theory of Inflation

Astronomers have found evidence to support the theory of inflation, which explains how the universe expanded so uniformly and so quickly in the instant after the Big Bang 13.8 billion years ago.

See the amazing ‘coffee cup’ example used in this article to explain the discovery.
