objects gravity center earth

Antigravity, hypothetical force of repulsion described in science fiction but never scientifically observed. The opposite of gravity, antigravity would cause objects to repel one another rather than to be attracted to one another. Earth's gravity pulls objects toward the planet's center, antigravity would push objects away from earth's center.
