We all know that the fundamental particles to be controlling the electric and magnetic forces in our universe are obtained in pairs(electrons and protons, north pole and south pole.) Likewise I guess it is safe to assume that even the weakest long range force,Gravity, also follows the same. So, is anti-gravity real or just a rubbish idea of my tiny brain?Also I think this might be related to the Quantum realms.
The particle that conveys the electromagnetic particle is the photon, not the electron or positron. The force between them is carried by photons; the photons themselves are not subject to the electromagnetic force.
The (hypothetical) graviton is a boson like the photon. And like the photon, the graviton is its own anti-particle. So there are no anti-gravity particles ;-(
