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 ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

Before there was light, there was cosmic inflation. Before life, planet Earth, the first galaxies — and even before the violent explosion of hot dense primordial stuff scientists traditionally have ...

The mysteries surrounding the origins of the universe have long intrigued scientists and philosophers alike. New research, published in the Living Reviews in Relativity, introduces an innovative ...

The Universe experienced a rapid expansion just after its birth, a phenomenon called cosmic inflation. This brief but intense phase left traces in the structure of spacetime. Scientists are trying to ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how ...

Is the universe 'tuned' to support life, and ultimately us? Physicists Nemanja Kaloper and Alexander Westphal have proposed ways to test this Anthropic principle. (Image of deep star field from the ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

The idea of a multiverse consisting of “parallel universes” is a popular science fiction trope, recently explored in the Oscar-winning movie Everything Everywhere All At Once. However, it is within ...
