How Anti-Gravity Work?
Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to countering the gravitational force by an opposing force of a different nature, as a helium balloon does; instead, anti-gravity requires that the fundamental causes of the force of gravity be made either not present or not applicable to the place or object through some kind of technological intervention. Anti-gravity is a recurring concept in science fiction, particularly in the context of spacecraft propulsion. The concept was first introduced formally as “Cavorite” in H. G. Wells’ The First Men in the Moon, and has been a favorite item of imaginary technology since that day. In the first mathematically accurate description of gravity, Newton’s law of universal gravitation, gravity was an external force transmitted by unknown means. However in the early part of the 20th century Newton’s model was replaced by the more general and complete description encoded in general rel
