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

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 ...

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.

The era of smashing two watermelons together at Brookhaven National Laboratory has ended. After 25 years of accelerating streams of ions into each other at the Relativistic Heavy Ion Collider (RHIC), ...

Researchers have identified rare proton emissions that reveal how the neck of a nucleus stretches and snaps, providing a new ...

For a mere moment after the Big Bang, no neutrons or protons are thought to have existed. These neutral and positively charged particles, respectively, make up the center of all atoms today. But ...

Physicists in Leiden have built a microscope that can measure no fewer than four key properties of a material in a single scan, all with nanoscale precision. The instrument can even examine complete ...

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