A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

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 ...

It was a bold thought experiment: that only one electron makes up the entire universe. The most famous conversation about it took place between Richard Feynman, PhD, and John Wheeler, PhD, both ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without waiting until 2070 for a new collider.

A neutrino slammed into Earth in 2023 with so much energy that it looked almost unreal. The particle carried about 220 peta–electron volts, or PeV, making it the most energetic neutrino ever reported.
