Experimental scientific concept in which gravity can be reversed, opposed or cancelled out in order to elevate or hover objects in the air. In science fiction anti-gravity is a futuristic technology used in everything from cars to spacecraft, in reality true anti-gravity is still a long way off. Progress has been made in the field of ion-propelled lifters which have in some cases been advertised as "anti-gravity lifters" due to their tendancy to hover in the air with no apparant means of propulsion however these do not exhibit true anti-gravity.
Some conspiracy theorists believe the United States and other countries have been in possession of anti-gravity technology for years, possibly reverse engineered from captured extraterrestrial spacecraft and that some UFO sightings can be attributed to experimental anti-gravity craft.
