Physicists have announced that antimatter falls downward, resolving a long-standing question in the realm of particle physics. The study, conducted by the ALPHA collaboration at the European Organisation for Nuclear Research (CERN) in Switzerland, sheds light on the elusive nature of antimatter.
In the 95 years we’ve known about antimatter, physicists have not tested how the elusive inverse of ordinary matter is affected by gravity, the force that pulls masses to Earth and seems to affect all things in the classical realm.
