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?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

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.
