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 ...

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 ...

That moment — theory and experiment finally shaking hands — an extraordinary scene in modern science. The Standard Model is stunningly ... and has been tested to better than one part in a billion in ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

One of the most enduring mysteries of particle physics may be finally resolved, two new studies suggest. The oddities of muons, subatomic particles that are relatives of electrons, are starting to ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of ...

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.

Wang Yifang, from the Chinese Academy of Sciences which collaborated with 700 physicists worldwide, told The Times: “We are ...

Hairs on the toes of Mexican free-tailed bats light up under ultraviolet light, but the reason is unknown, Jason Bittel reported in “Mexican free-tailed bats’ toes glow in the dark” (SN: 8/28/24).
