For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but ...

A new model suggests that the universe did not undergo a Big Bang followed by inflation, as the prevailing model suggests, but a cycle of "bounces". Though so very far from anything approaching ...

A new study suggests that the cosmic web could have formed without relying on inflation driven by a scalar field. Instead, it ...

If the universe sprung forth in this manner, then probably inflation has occurred in other places, perhaps an infinite number of places, beyond our horizon and outside of our time. The implication ...

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 ...

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.

Cosmologists believe that our universe underwent a period of incredibly rapid expansion known as inflation. Powering this event was some mysterious substance in the universe, known as the ...

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 ...

Cosmic inflation is a faster-than-light expansion of the universe that spawned many others. Inflation was invented to explain a couple of features of the universe that are really hard to explain ...

and created all the matter and energy in the universe. Exactly what triggered this sudden expansion remains a mystery. Astronomers believe it involved a runaway process called "inflation," in ...
