We break down CERN's ALPHA experiment breakthrough that uses laser-cooled beryllium ions to sympathetically cool positrons, effectively chilling antihydrogen production and trapping. By keeping the cooling ions separate, Coulomb coupling acts like a refrigerator for the positrons, enabling much colder antihydrogen and an eightfold speed-up in trapping—over 15,000 atoms in less than seven hours, versus weeks before. This breakthrough opens the door to precision tests of matter–antimatter symmetry, gravity on antimatter, and the possibility of beams or fountains of antihydrogen in the future.
