For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

Most of the matter and energy in the cosmos does not shine, yet its presence is written into the way galaxies twist, stretch, and smear across the sky. By treating those warped galaxies as data rather ...

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical ...

Dark matter and dark energy are mysteries that have confounded scientists for decades, even though they comprise 95% of the universe's mass.

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 ...

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 ...

Dark matter is thought to exist everywhere, wrapping around galaxies and helping to shape the largest things in the universe.

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology ...

Dark energy refers to the force behind the universe's accelerating expansion. Put simply, dark matter acts like cosmic glue, while dark energy drives space itself to expand faster and faster. Although ...

We may have seen the first hints of strange stars powered by dark matter. These so-called dark stars could explain several of the most mysterious objects in the universe, while also giving us hints ...
