Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly ...

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 ...

NASA’s Nancy Grace Roman Space Telescope will conduct a wide-area survey to study dark matter, dark energy, and the expansion of the universe across 11 billion light-years.

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

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 may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our place within the multiverse.
