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 ...

There's a significant imbalance between matter and antimatter in our universe, but a strange particle called "the Majoron" could finally explain it, an audacious new study suggests. When you purchase ...

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 ...

If I can understand the particle in a box, I can understand quantum mechanics, which means, maybe, I can understand, like, you know, life. This notion popped into my head three years ago, and it’s ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

A hidden family of "ghost particles" may be responsible for all the dark matter in the universe — and the reason that there is any matter at all, a recent preprint study suggests. One of the most ...
