I've always been interested in anti-gravity and how you could do it. I know that it would make space travel easier because less fuel would be required, but is it possible?

1 Answer 1

Diamagnetic materials (including superconductors) experience a force in a magnetic field gradient, in the direction of decreasing field. If the force is in the opposite direction of the force of gravity this is referred to as levitation.

Even a live frog has been levitated

However, this does not directly lead to improved spaced travel. You need energy to make the magnetic field.
