Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

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 ...

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 ...

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 ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Physicists are still chasing the dream of Albert Einstein and Stephen Hawking to capture the workings of the entire universe in a single equation. When you purchase through links on our site, we may ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...
