A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these particles within atoms would stay unexplained without this tool.

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground. The electromagnetic force ensures the stability of atoms and makes chemistry happen.

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 remain undetectable due to their scarcity.

Dark matter has bewildered scientists for centuries. It makes up most of the universe’s matter, but it can’t be seen directly.

New research from North Carolina State University and Michigan State University opens a new avenue for modeling low-energy nuclear reactions, which are key to the formation of elements within stars. The research lays the groundwork for calculating how ...

Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says they’ve figured out how to use a sensor-laden patch of ice near the South Pole to ...
