Anti-gravity refers to the concept of counteracting or neutralizing the effects of gravity. In physics, gravity is the force that pulls objects toward one another, particularly towards the Earth. The idea of anti-gravity suggests a method or technology that can create a force opposing gravity, allowing objects to float or move freely without being pulled down. While anti-gravity is often depicted in science fiction, such as in Star Wars or Star Trek, it remains a theoretical concept in real-world physics. Current scientific understanding does not support the existence of true anti-gravity, but researchers explore related ideas, such as magnetic levitation and quantum mechanics, to understand gravitational effects better.
