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 ...

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...

At the end of a lecture on astronomy, describing how the planets orbit the Sun, a little old lady at the back of the room stood up and said: "What you've told us is all rubbish. The world is really a ...

This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While the universe is populated by visible stars and galaxies, much of its mass ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the universe's mass. While theoretical predictions hint at its abundance, detecting this ...

Decades after it became clear that the visible Universe is built on a framework of dark matter, we still don’t know what dark matter actually is. On large scales, a variety of evidence points toward ...

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 ...

If you could step back a few quadrillion miles and look at the Milky Way from the outside, you’d see a magnificent, glowing pinwheel of stars and gas, its arms curving majestically outward from a huge ...

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 ...
