Findings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy could be evolving over time. If they're right, cosmology will need a new model. When you purchase through links ...

Data on dark energy weakening over time may signal that if the trend continues it could eventually cause the universe to collapse, according to a new study. Mustapha Ishak-Boushaki, a physics ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the universe’s accelerating expansion. Now a new wave of data is forcing ...

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 years ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe's greatest mysteries. The most widely accepted theory currently suggests ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

Researchers have presented new measurements that account for half of the universe’s hydrogen gas — which had previously been regarded as “missing” in cosmic scientific discourse. The study was ...
