A mathematical investigation of galactic data suggests elusive dark matter is confined to the rules of gravity.

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 ...

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 ...

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 ...

An artist’s concept of the dark energy-driven accelerating expansion of the universe. New results suggest dark energy’s influence on cosmic expansion has weakened over time. In 2024 a shockwave ...

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 ...

An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a ...

In 2024 a shockwave rippled through the astronomical world, shaking it to the core. The disturbance didn’t come from some astral disaster at the solar system’s doorstep, however. Rather it arrived via ...

Dark energy, the mysterious force driving the accelerated expansion of the universe, has puzzled scientists since its discovery in 1998. Despite its elusive nature, dark energy is believed to ...

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 ...

Dutch string theorist Dr. Erik Verlinde insists on saying gravity doesn't exist. The good professor clearly does not believe that if he stops holding onto his briefcase, it will do anything other than ...
