Dark energy and black holes are two of the most mysterious topics when it comes to space, but they might actually be linked.

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda Cold Dark Matter, or ΛCDM, it weaves together dark energy, dark matter, and ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

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 ...

A new study suggests observational evidence that matter falling into black holes could be converted into dark energy, a component comprising 70% of the cosmos and accelerating its expansion. This ...

WASHINGTON (Reuters) - New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible ...

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 ...

Dark energy, the mysterious force that makes up 70 percent of everything in existence, was hypothesized to explain why the expansion of the universe was accelerating. Ever since, it’s been thought of ...

DESI maps distant objects to study dark energy. The instrument is installed on the Mayall Telescope, shown here beneath star trails. The fate of the universe hinges on the balance between matter and ...

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought.See an excerpt of an interview in the video aboveAstronomers know ...
