Physicists trap a single antimatter particle for a month
Researchers have succeeded in holding a single antimatter particle for about a month, a record duration that could allow more precise studies of antimatter's properties. Antimatter particles normally annihilate almost instantly on contact with ordinary matter, so confining one for weeks requires extremely delicate magnetic trapping. Scientists say the achievement could sharpen tests of whether antimatter behaves identically to matter, a fundamental question in physics.
Why now: The result pushes the limits of how long antimatter can be confined, a major technical milestone in fundamental physics research.
