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

In modern physics, antimatter is defined as matter composed of the antiparticles of the corresponding particles in "ordinary" matter, and can be thought of as matter with reversed charges and parity,

…lifters", which fly in the air by moving air with electromagnetic fields. Historically, anti-gravity was considered a possibility after the discovery of antimatter. Once the nature of antimatter was more clearly established, it was clear that gravity works the same for both matter and antimatter. Anti-gravity is…
