Antimatter responds to gravity like Einstein predicted, major CERN experiment confirms

[fliptopfish]

Ok matter and antimatter respond to gravity nearly the same but close or near isn't exactly the same and even small differences can add up to a lot of difference when we are dealing with very large masses in fact it can make a huge difference
if we are wondering where all the anti matter in the early universe went and they can't work out how there are such massive black holes in the early universe has anybody considered that's maybe where all the antimatter went

The CERN result does seem to rule out the idea that "antimatter" could really be a "hole" in undetectable matter in a "false vacuum" state of regular matter. The hypothesis is that energy added to a bit of matter that is in that state results in elevating it to a "positive" energy state that we can detect, and at the same time leaves a "hole" in the rest of the matter in the undetectably low state that we interpret as an anti-particle. But, that hole should exhibit anti-gravity, is one assumes that the regular matter in the undetectable energy state is still gravitationally attracted to regular matter in higher energy states that we can detect - which would make it some form of "dark matter".
