The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with ...

However, new findings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy’s effects may be evolving over time, challenging our understanding of the universe’s ...

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought.

CHRISTCHURCH, New Zealand — Dark energy has been modern physics’ most successful placeholder, a theoretical force invented to explain why galaxies seem to be racing away from each other at ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of ...

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy.

For centuries, people have looked to the stars, asking how it all began—and how it might end. Now, thanks to a bold new study ...

New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible for the universe's ...

Even if DESI’s findings hold up, they still can’t say what dark energy is. But they can provide much stronger clues than cosmologists had before.
