Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Experiments with hydrogen atoms could soon reveal whether particles that were long thought to be forbidden by physics ...

A bold new quantum theory of gravity may finally bridge the long-standing rift between Einstein’s general relativity and ...

The greater the cosmic-ray energy, the greater its interaction cross-section, meaning it is more likely to interact with CMB ...
