Researchers are left looking for other models that could fit this strange behavior: Perhaps dark energy interacts with other entities like dark matter, or maybe it’s the joint work of two different ...

Only about 4% of the total energy density in the universe ... interact with ordinary matter via electromagnetic forces. The nonbaryonic dark matter includes neutrinos, which were discovered ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

Three years later, two competing teams of astronomers discovered that the expansion of the universe was being accelerated by a “dark energy” acting as the cosmological constant, pushing ...

Since then, there has been "cosmic tug-of-war" between two mysterious forces, Joshua Frieman, a theoretical astrophysicist at the University of Chicago, told AFP. Dark matter is thought to pull ...

Last month, a press release announced groundbreaking findings from the Dark Energy Spectroscopy Instrument (DESI), which is installed on the Mayall Telescope in Arizona. This vast survey, containing ...

Dark Energy 'Doesn't Exist' So Can't Be Pushing 'Lumpy' Universe Apart Dec. 20, 2024 — One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers ...

Katy is Managing Editor at IFLScience where she oversees editorial content from News articles to Features, and even occasionally writes some.

"There are more questions than answers at this point." Dark energy could have an accomplice that helps it slow the growth of large cosmic structures, such as vast superclusters made up of clusters ...

DESI’s 3D map suggests dark energy may not be constant over time Findings challenge the standard model of cosmology and cosmic expansion Scientists await more data to understand dark energy’s true ...

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 ...
