A theoretical point in space where all effects of gravity are cancelled out evenly by all other objects in the universe.
That point probably doesn't exist, given the asymmetry of the observable Universe, but it may exist temporarily in various locations. It will move, and if that point moves through space, you really can't prove your idea as valid.
