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 ...

Science’s best guess at how the universe came into being includes the Big Bang followed by a moment of rapid inflationary expansion. However, this theory left a few mysteries and quirks in its ...

While the Big Bang Theory is widely supported within the scientific community, some researchers propose alternative ideas, such as eternal inflation or a cyclical, oscillating universe.

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 multiverse theory, a mind-bending concept, proposes that our universe is not alone. Instead, it suggests a vast sea of universes, each with its own ...

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 ...
