Cosmic inflation is a popular scenario for the earliest phase in the evolution of the Universe CREDIT A. Ijjas, P.J. Steinhardt and A. Loeb (Scientific American, February 2017) Astrophysicists say ...

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

A new analysis of the South Pole-based telescope's cosmic microwave background observations has all but ruled out several popular models of inflation. Physicists looking for signs of primordial ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

“However, the large flexibility displayed by possible models for cosmic inflation which span an unlimited landscape of cosmological outcomes raises concerns that cosmic inflation is not falsifiable, ...

Physicists looking for signs of primordial gravitational waves by sifting through the earliest light in the cosmos—the cosmic microwave background (CMB) – have reported their findings: still nothing.
