A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

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 ...

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 ...

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 ...

Only after adding a massive, invisible halo of dark matter to their computer models could the researchers reproduce what they saw in space. When you purchase through links on our site, we may earn an ...

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 ...

Black hole discovery reshaped astrophysics by proving that some of the universe's most powerful objects cannot be seen directly but can be measured through their effects on space and time. Signals ...
