Physicists Trap a Single Antimatter Particle for a Month
Physicists have confined a single antimatter particle for about a month, a record-breaking feat in antimatter research. Antimatter particles normally annihilate almost instantly on contact with ordinary matter, so keeping one stable for weeks requires extreme isolation and precision. Scientists say the achievement could open new ways to study antimatter's properties, including testing whether it obeys the same laws of physics as matter, a question tied to why the universe contains so little antimatter.
Why now: A record-long confinement of antimatter is a striking scientific milestone that touches on fundamental questions about the universe.
