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 ...

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 ...

For a while now, there has been a problematic mystery at the heart of the standard cosmological model. Although all observations support the expanding universe model, observations of the early period ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

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 ...

Dark energy makes up about 70% of the universe and causes its expansion to accelerate. It's different from dark matter; dark energy pushes space apart, while dark matter pulls things together. We ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming that dark energy—a mysterious force making up 70% of the cosmos—remains ...

All the atoms and radiation in the universe make up less than 5 percent of its contents. The rest is composed of two invisible, enigmatic entities: dark matter and dark energy. Together they govern ...

"Although there have been multiple efforts to understand the nature of dark energy, its composition, and its manifestation in the universe," one expert says, "we know embarrassingly little about it." ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...
