Now, recent findings released March 19 from two of the largest cosmological surveys to date - the Dark Energy Spectroscopic Instrument (DESI) survey and the Dark Energy Survey (DES) - challenge ...

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 ...

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 ...

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

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

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

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 ...

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.

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

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.
