On March 19, the Dark Energy Spectroscopic Instrument (DESI) collaboration shared its findings in multiple papers posted on arXiv and in a presentation at the American Physical Society's Global ...

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 ...

"Our findings in DESI that the dark energy is evolving in time and is not the cosmological constant is probably the most important result about cosmic acceleration since its discovery in 1998 that ...

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

Space Dark energy bombshell sparks race to find a new model of the universe ‘Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing ...

Suppose, though, that dark energy had a different strength, making the universe's expansion accelerate either faster or slower. Sorini, along with John Peacock of the University of Edinburgh and ...

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 ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

If dark energy is weakening, as suggested by recent results, ... For w(z) greater than –1, the universe’s dark energy dilutes over time, consistent with DESI’s findings.

The Vera C. Rubin Observatory released a sneak peak of some of the images it is unveiling, the first set of space images from ...

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 ...
