Particle that goes along with the force of gravity?

[BigStelly]

This question may have been posed before but, is there a particle that goes along with the force of gravity? And if so does it thereby follow the possibility of the existence of antigravity particles? Any info appreciated thanks

The particle that is associated with gravity is called the graviton. They have yet to be directly detected, but we do know something about what ype of properties they would have to exhibit. One of these properties is that, like photons, gravitons would be their own antiparticles. Thus there would not be an "anti-graviton".
