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 ...

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped physicists make sense of the tiniest building blocks of the universe.

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 ...

Knowable Magazine reports that neutrinos may help explain the universe's missing antimatter, shedding light on matter-antimatter imbalance.

The newly found antiparticle, called antihyperhydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be. When you ...

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

China’s ‘ghost particle’ machine could solve science’s greatest mysteries - A futuristic underground observatory located in the hills of China could uncover a whole host of secrets ...

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).

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...
