anti-gravity
Fictional floating force
Anti-gravity is the hypothetical ability to counteract or neutralize gravitational force.
Though a staple of science fiction—The spacecraft's anti-gravity drive allowed it to hover silently—no technology exists that actually cancels gravity.
The term appears in discussions of speculative physics and futuristic propulsion systems.
