Tests at Cern refute suggestion that antigravity might apply to antimatter, showing instead it also falls downwards
Galileo put gravitational theory to the test by dropping balls from the Leaning Tower of Pisa. Four hundred years on, scientists have performed a higher tech version of the experiment to demonstrate for the first time that antimatter also falls downwards.
The study, by scientists at Cern, showed conclusively that gravity pulls antihydrogen downwards and that, at least for antimatter, antigravity does not exist.
