Scientists talk about dark matter an awful lot for something they don’t actually understand very well. They say that it’s important — and that we wouldn’t have stars and galaxies without it — though ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Frank Close tells us about the history of particle physics, and what it means that charge in our universe's matter is so closely balanced. When you purchase through links on our site, we may earn an ...

Dark matter, the substance that makes up about 27% of the universe, could potentially be detected as a red or blue light ...

Physics has a bit of a messy problem: There's matter missing in our universe. Something is there that we can't see, but scientists can detect. "When we look at how stars move in galaxies, they move as ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...
