Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

Dark matter particles outnumber ordinary matter in the cosmos by about one to five, but scientists don’t yet know what these abundant particles actually are. Thus far, the most heavily favored ...

The universe has cooked up all sorts of bizarre and beautiful forms of matter, from blazing stars to purring cats, out of just three basic ingredients. Electrons and two types of quarks, dubbed “up” ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up most of the observable universe. Reading time 3 minutes All matter in our ...

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought ...
