How did scientists drive antimatter down a highway — and make sure it survived?

Antimatter vanishes when it touches ordinary matter, so the feat depended on trapping antiprotons with electromagnetic fields inside an ultra-high-vacuum system and protecting that apparatus from vibration and power loss during transport. Moving the experiment to other facilities could let researchers compare measurements without building a new antiproton source at every lab. The “cargo” was not loose antimatter; it was a carefully confined particle sample inside specialized equipment.
