Dark energy, one of the most mysterious concepts in astronomy, has baffled the world's greatest minds for decades. Dark energy is a placeholder term scientists use to refer to whatever is causing ...

The enigmatic idea of dark energy has consistently been referenced to explain the universe’s expansion, but new research may upend years of cosmological beliefs with a shocking claim made by ...

"Up to this year, most observations were consistent, with dark energy being the cosmological constant. Nonetheless, 2024 was full of hints pointing out this might not be the case." 2024 was a big ...

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

We're showing a tremendous new ability to probe modified gravity and improve constraints on models of dark energy. And it's only the tip of the iceberg." The DESI results are described in several ...

Dark energy and dark matter refers to the unseen energy and matter components of the Universe. Dark matter is invisible, non-baryonic matter hypothesized to explain phenomena including ...

Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief.

The Dark Energy Survey examines the largest-ever maps of galaxy distribution and shapes, extending more than 7 billion light-years across the Universe. The extraordinarily precise analysis ...

An international consortium of scientists studying dark energy said Tuesday their three-dimensional map of the universe over 11 billion years suggested the cosmos wasn't steadily expanding ...

The LUX ZEPLIN (LZ) Dark Matter experiment is a large research ... This additional data could allow the team to set further constraints on WIMP interactions, potentially contributing to the ...
