What can antigravity be used for?

If proven to exist, this ‘repulsive force’ could assist in our quest to travel among the stars

Gravity shields

Gravitational shielding involves shielding an object from the influence of a gravitational field. Currently bound to the pages of science fiction, gravity shields have the effect of reducing the weight of an object, assisting greatly with space travel.

Opening up a wormhole

In theory antigravity could be used to open up a wormhole in order to allow spacecraft to dive straight in and travel straight through. By using a sufficient torrent of antigravity – which acts as negative energy – to force the throat of spacetime apart, a path could be opened wide enough to enable an astronaut and their spacecraft to slip right though.

Navigating space-time faster than light

The Alcubierre warp drive, which is based on Einstein’s field equations in general relativity, is a speculative idea by which a spacecraft could achieve apparent faster-than-light travel – that’s if a configurable energy-density field lower than that of a vacuum is able to be created.

By creating antigravity, and a ‘drainhole’ to create the drive, the spacecraft would be shielded from external gravity and could even go below a black hole’s horizon unscathed.
