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 ...

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.

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

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 ...

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.

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 ...

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 ...

If dark energy is weakening, as suggested by recent results, then the cosmos is far stranger than most physicists had supposed ...

The findings could undermine the existing standard cosmological model of the universe called the lambda-cold dark matter (LCDM) model, which takes dark energy, ordinary matter, and cold dark ...

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.
