anti gravity

As far as i'm aware thers no such thinhg as anti-gravity. Gravity is a force that attracts two objects and depends on there size and seperation, there is no such force that will push them apart. Scientists have done work on levitation, this is essentially causing objects to float. These experiments are generally performed with superconducting magnets, although i'm not too sure how they work.

Well i never heard such thing before but surely it is a great thing to work on. do you know what were the experiments. Were the scientists actually successful in proving anti-gravity?
