Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

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 ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by ...

Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

(via Sabine Hossenfelder) Physicists don’t actually know what the universe is really made of. The currently most popular theory is that most of the universe is made of dark matter, a mysterious type ...

At the centre of our galaxy lies a supermassive black hole called Sagittarius A* – but one group of researchers is suggesting it may not be a black hole at all. The team says that it, and other black ...
