AntiGravity
Anti-gravity is the concept of a force that would exactly oppose the force of gravity. Under the known laws of physics, anti-gravity is impossible except possibly between matter and antimatter. Experimental measurements rule out repulsion between antihydrogen and the mass of the Earth.
Anti-gravity does not refer to either the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism, aerodynamic lift, or ion-propelled "lifters", which fly in the air by moving air with electromagnetic fields.
Anti-gravity is a recurring concept in science fiction.
