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 new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

A puzzling ultraviolet light seen across the Milky Way could come from the destruction of nuggets of dark matter, the mysterious stuff that makes up around a quarter of the matter and energy in the ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers ...

"Dark matter interacts gravitationally, so it could be captured by stars and accumulate inside them," explained co-author Jeremy Sakstein in a press release. "If that happens, it might also interact ...
