Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two ...

Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests the missing ...

The Milky Way’s center glows with an unexplained surplus of gamma rays. Smaller galaxies orbiting nearby do not. That mismatch has nagged at physicists for more than a decade, and a new theoretical ...

Two experiments designed to detect signals directly found no evidence for the signal reported by an earlier experiment.

For decades, dark matter has been treated as the unseen framework around which galaxies take shape. Even the smallest galaxies are generally thought to be wrapped inside vast halos of it, with the ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

A 2021 paper proposed that fermionic dark matter could inhabit a warped fifth dimension. The model uses a new scalar field as ...

A new kind of dark matter could help explain some of the universe’s mysteries, a new study suggests. The study proposes that there are dense clumps of “self-interacting dark matter”, or SIDM, each ...

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments. Published in Physical Review ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

The Big Bang may not mark the absolute beginning of everything. A controversial cosmological model instead treats it as a ...
