Scientists propose that gravitational waves shaped the universe. Their model challenges inflation theory. How exactly did the ...

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

An artist's impression of how the very early universe (less than one billion years old) might have looked when it went through a voracious onset of star formation, converting primordial hydrogen into ...

Scientists are investigating the possibility that our universe isn't the only one after detecting a mysterious gravitational wave ...

How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that large question. Called SPHEREx, and set for launch on a SpaceX Falcon ...

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 ...

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 ...

Science’s best guess at how the universe came into being includes the Big Bang followed by a moment of rapid inflationary expansion. However, this theory left a few mysteries and quirks in its wake, ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

One possibility to explain the constants of nature is that there’s more than one universe. That we live in a multiverse, with ...
