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 voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology.

For nearly three decades, astronomers have interpreted the faint luminosity of certain distant explosive stars as a sign of the Universe's runaway expansion. An inexorable acceleration, attributed to ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

For a fraction of a second after the big bang occurred 13.8 billion years ago, most physicists believe, the newborn universe dramatically ballooned in size, jumping from being smaller than a proton to ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

According to a new theory, our universe developed from a “pre-inflationary multiverse” made of particles in quantum superposition.
