Antimatter falls like matter, confirming Einstein's theory of gravity

Antimatter falls like matter, confirming Einstein's theory of gravity

It's official: antimatter is falling, not rising. In a first-of-its-kind experiment, scientists dropped antihydrogen atoms and watched them fall, demonstrating that gravity pulls antimatter toward Earth, rather than pushing it away. The study confirms a pillar of Einstein's general theory of relativity known as the weak equivalence principle. According to this principle, gravity pulls on…

Antimatter falls like matter, upholding Einstein’s theory of gravity

It’s official: Antimatter falls down, not up. In a first-of-its-kind experiment, scientists dropped antihydrogen atoms and watched them fall, showing that gravity attracts antimatter toward Earth, rather than repelling it. The study confirms a pillar of Einstein’s general theory of relativity known as the weak equivalence principle. According to that principle, gravity pulls on every…
