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 ...

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 ...

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

Lawrence Berkeley National Lab, or Berkeley Lab, researchers mapped nearly six million galaxies throughout the past 11 billion years of cosmic evolution using the Dark Energy Spectroscopic Instrument, ...

A mysterious force called Dark Energy might be changing, in a way that challenges our current understanding of the nature of time and space.

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 ...

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 ...

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 ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?
