I was thinking of such thing as this quite some time ago. The analogy of like magnetic charges repeling each other made me think this. I just can't get the answer as to if that is possible. Someway I believe someone will discover that. And then the science fiction movie of the 5th element will be realized. Cars will fly on the air- I can't wait to see that.

Since the gravitational force of any object acting on another is never fully equal to 0 no matter how far away it is, it is impossible to physically exist in any spot in the universe and not be affected by gravity. It is, however theoretically possible, to be at a point where all the forces of gravity cancel each other out and you experience a net force of zero. As for anti-gravity... not really... gravity always pulls objects in. There is no such thing as anti-gravity.

I think something that simulates it is very possible. However, not without the expense of energy. I think by definition, gravity can not have a reverse effect. Although, I am wondering if you had negative mass (say through anti-matter) if anti-gravity could exist then. As gravity depends on masses, so it could be possible this way.
