When it comes to primordial black holes being dark matter suspects, their alibi may be falling apart. Tiny black holes, created seconds after the birth of the universe, may survive longer than ...

Physicists at the world's largest atom smasher have detected a mysterious, primordial particle from the dawn of time. About 100 of the short-lived "X" particles — so named because of their unknown ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an evaporating black hole. According to a new theoretical paper, the 2023 ...

One of the most puzzling known particles of the atom is the neutron, the uncharged building block of the nucleus. To explain its lack of electrical charge, nuclear physicists have long supposed that ...

Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator exploring nuclear physics and the building blocks of matter, have new evidence for what's called a ...

A few billionths of a second after the Big Bang—currently the most widely accepted theory of how the universe was formed—elementary particles, including protons and neutrons, did not exist. Instead, ...
