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 not possible. Experimental measurements rule out repulsion betwe

Antihydrogen is the antimatter counterpart of hydrogen. Whereas the common hydrogen atom is composed of an electron and proton, the antihydrogen atom is made up of a positron and antiproton. Scientist

…exactly oppose the force of gravity. Under the known laws of physics, anti-gravity is not possible. 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…
