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 ...

The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

The widely accepted theory of cosmic inflation states that our universe expanded rapidly in the moments after its birth, resulting in the immense expanse we see today. Cosmic inflation explains why ...

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 ...

How did the universe come into being? There are a multitude of theories on this subject. In a recent paper, three scientists formulate a new model: according to this, inflation, the first, very rapid ...

“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, ...

A new analysis of the South Pole-based telescope’s observations has all but ruled out several popular models of inflation. Physicists looking for signs of primordial gravitational waves by sifting ...
