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

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 ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for ...

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 ...

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, ...

In this video, we explore the origins of the first atom, tracing back to the big bang, where immense energy condensed to form atoms. Key concepts include: - The uncertainty surrounding events before ...

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 ...

“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, ...
