Dark energy, an unusual force associated with the expansion of the universe, may one day cause the cosmos to collapse, according to a new theory proposed by scientists. Over the last few months, there ...

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 ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

On a quiet mountaintop in southern Arizona, 5,000 robotic eyes scan the sky every night, each locking onto a galaxy billions of light-years away. This interesting instrument, called DESI, has now ...
