antigravitation
Defying downward pull
Antigravitation is a hypothetical force that would oppose or counteract gravity, allowing objects to repel rather than attract one another.
The concept appears frequently in science fiction—antigravitation drives powering spacecraft, antigravitation fields lifting heavy objects.
In physics, no such force has been demonstrated, though researchers occasionally investigate whether gravity can be shielded or reversed.
Also called antigravity.
