The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions with matter.

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...
