The anti-hydrogen atoms and the hydrogen atoms, were not free to decide on their own, because, they were trapped in a magnetic field which left them with no choice(s). They need to try the experiment again with no magnetism involved, since magnetism involves using regular matter. Try the experiment again with ‘anti-magnetism’ and then we can talk about whether anti-gravity exists or not.
(just nit-picking)
I’ve heard that anti-Fa doesn’t exist, that it’s a myth. Let’s have these scientists do experiments on that, and perhaps then we’ll have a definitive answer. ;)

No, it only restricted their movement laterally. They were free to move up or down, and they all “chose” down.
