A speculative framework proposing the existence of "anti-mass"—a hypothetical property of matter that would produce negative gravity, repelling rather than attracting other masses. Unlike negative mass (which would fall up), anti-mass might be a distinct property, perhaps related to antimatter but different, that could enable exotic phenomena like gravity shielding, propulsion without propellant, or stable wormholes. The theory suggests that just as there is antimatter (opposite charge), there might be anti-mass (opposite gravity). If it exists, anti-mass would revolutionize physics—and space travel.
Theory of Anti-Mass "Dark energy pushes the universe apart—some kind of repulsive gravity. Anti-Mass theory asks: what if that's a property matter can have? Anti-mass objects would repel normal matter, not attract it. Build a ship with anti-mass, and it falls up, not down. The theory is speculative, but so was antimatter once."
