A Matter of Deepest Gravity

Scientists at CERN in Switzerland appear to have shown that there's no such thing as antigravity. Antimatter is the mirror image of matter. It's made of antiprotons (with the same mass as a proton but a negative charge) and positively-charged antielectrons. The scientists made antihydrogen (an antiproton with an associated antielectron) and subjected it to gravity. It 'fell' downwards, just like regular hydrogen (https://www.theguardian.com/science/2023/sep/27/scientists-find-antimatter-is-subject-to-gravity). Antimatter doesn't have an antigravity alternative. Only certain politicians and particularly noxious 'celebrities' appear to fall upwards.
