"These results from the Dark Energy Survey shine new light on our understanding of the universe and its expansion." ...

The James Webb Space Telescope has confirmed the most distant, early galaxy in the known universe. The new contender, MoM-z14, is visible just 280 million years after the Big Bang.

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...

This December, the SciFri Book Club will read The Biggest Ideas in the Universe: Space, Time, and Motion by Sean M. Carroll. This New York Times bestseller transforms intimidating physics equations ...

Consciousness could be a fundamental part of reality, like gravity or matter, according to this controversial theory.

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...
