Physicists know that something unseen is sculpting the cosmos, outweighing ordinary matter by roughly a factor of five, yet every detector built so far has come up empty. One of the most audacious ...

Astronomers have shed light on a decades-long debate about why galaxies rotate faster than expected, and whether this behaviour is caused by unseen dark matter or a breakdown of gravity on cosmic ...

A new study in the journal Nature examines the distribution of dark matter in the universe, attempting to figure out if it obeys the same laws as regular matter. What it found suggests that dark ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced. Reading time 4 minutes Astronomers have spent nearly a century ...
