If antimatter has everything backwards why not gravity too? If it has negative gravity then it would repel itself into single particles spread rather uniformly in the space. You would say then why don't we detect small annihilations when traveling in space? Maybe all the massive objects in the solar system overpowered their negative gravity and annihilated them long ago, maybe there isn't much antimatter left inside the galaxies either.

Is it possible to detect such properties of the antimatter inside a lab? Have anyone tried this yet?

Would this not violate the equivalence principle?

 

And what about photons which are their own antiparticles? We will run into some inconsistencies I suspect.
