Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

Trillions of neutrinos—nearly massless, neutrally charged particles—pass through us every second, but we only acknowledge ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

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

"We are moving from post-diction to prediction," said Raghu Kulkarni. "These papers demonstrate that the confusing constants ...

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly ...

New analysis by Francesca Capel and Nadine Bourriche narrows possible sources of the Amaterasu cosmic ray, suggesting nearby galaxies like M82 rather than the Local Void.

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...
