The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its accelerating expansion. New results from the Dark Energy Spectroscopic ...

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 ...

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 ...

Cosmology’s neat story of a universe driven apart by a simple, invisible “cosmic fuel” is starting to fray. A growing body of ...

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 ...

Scientists with the Dark Energy Spectroscopic Instrument (DESI), an international research collaboration, presented new evidence Wednesday that bolstered its recent finding that dark energy is not ...

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 ...
