For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of fundamental particles heated to trillions of degrees. But this seething primordial ...

It's the second most energetic cosmic ray ever to be detected striking Earth. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Breaking space news ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties and—perhaps oddest of all—particles that spontaneously spring into being from the ...

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion ...

For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, ...

On February 10, 1958, scientists at MIT's Lincoln Laboratory bounced radar waves off of Venus. At the time, Venus was at a point in its orbit called inferior conjunction, where it is directly in ...

Fundamental particles called quarks can be created in quantum-correlated pairs. These correlations can be passed on to larger particles that form from the quarks. The strong force differs from others ...
