Is dark energy dead? The new findings aren't definitive. Astronomers say they need more data to overturn a theory that seemed to fit together so well.

However, if dark energy is now weakening, as DESI’s findings suggest, it would mean that our entire framework for understanding the cosmos needs revision.. What DESI’s Data Reveals About Dark ...

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, ... the DESI findings don't actually challenge the picture of dark energy developed in the LCDM model.

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 ...

“Our findings show that we do not need dark energy to explain why the universe appears to expand at an accelerating rate. Dark energy is a misidentification of variations in the kinetic energy ...

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 Spectroscopic Instrument (DESI ...

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

Evidence is mounting that cosmic dark energy, long thought constant, may weaken with time - potentially altering the fate of ...

Dark energy, a mysterious force ... An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical ...

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. The DESI-based model implies that dark energy ...
