Scientists have been using complicated, hypothetical particles to explain the Big Bang, but this theory posits that a simpler ...

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted. reading time 5 minutes Following the Big Bang, ...

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 ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

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 ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...

Pulsars could be helping scientists distinguish between gravitational waves caused by supermassive black hole collisions and ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and that black holes appeared later. But some have proposed that it went the other ...
