Scientists have found evidence that a relatively recently discovered subatomic particle is breaking the existing laws of physics. It’s not clear what forces are influencing the particle, and there is ...

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.

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, and although ...
