Science News | Just like matter, antimatter falls under gravity’s pull | Science News @ScienceNewsMag | Uploaded October 2023 | Updated October 2024, 11 hours ago.
Researchers contained antihydrogen atoms within the ALPHA-g apparatus using magnetic fields. The team measured how the atoms fell when they were released. As the antimatter escaped, it hit the walls of the apparatus and annihilated. The researchers counted how many atoms went up and down by detecting those annihilations, as depicted in this animation. Most atoms went down, confirming that gravity pulls antimatter toward Earth, rather than repelling it.
