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.
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 known as general relativity. In general relativity, gravity is not a force in the traditional sense of the word, but the result of the geometry of space itself. These geometrical solutions always cause attractive "forces".
Propulsion Technologies
The term anti-gravity is also sometimes used to refer to hypothetical reactionless propulsion drives such as Biefeld Brown Effect Lifters and Beam Propulsion technologies like EMDrive.com and Microwave Phase Conjugators. Although these do oppose gravity, they cannot be consider true anti-gravity machines.
The Need for New Physics
Einstein's derivations explain gravity, yet they do not coincide with the laws of Quantum Mechanics. Both theories are incomplete, and the hunt is on for a Unified Field Theory of physics.
High Energy Physics
Most of mainsream physics is convinced that the answer will be found at extremely high energies. This is the reason for building the Large Hadron Collider (LHC) at CERN, which is the world's biggest particle accelerator. The picture on the left is of ATLAS, which is a huge array of various particle detectors. The idea is to accelerate 2 protons, in opposite directions. Get them going so fast that their Kinetic Energy is equal to two Titanics crashing at full cruising speed. All that energy is concentrated onto a single point as the two protons are made to collide inside of this giant room full of detectors.
