String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

On July 4, 2012, researchers at the Large Hadron Collider (LHC) in Switzerland announced with great fanfare that they had ...

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 ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, ...

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate ...
