CERN researchers took a few antimatter particles for a walk in an unprecedented transportation test

Forward-looking: Antimatter consists of particles with properties opposite to those of regular particles. It plays a central role in modern physics research and forms naturally through cosmic collisions or radioactive decay. However, studying it is difficult, as contact with normal matter results in instant annihilation.

The European Organization for Nuclear Research, better known as CERN, is one of the few places on Earth capable of routinely producing antimatter from high-energy collisions with particle accelerators. Researchers there have now developed a novel method to transport small quantities of antimatter to external laboratories. This world-first achievement could enable more precise studies of the elusive antiparticles described in the Standard Model of particle physics.

CERN researchers developed a two-meter containment device capable of temporarily trapping antimatter particles. They even trucked the device around the facility for four kilometers before returning it to the lab, where they confirmed the antiparticles were still intact.
