: Rich: : It is theoretically possible to nullify gravity at the center of a very large mas such as the earth or a black hole. Of course, that is not very practical. Gravity can be nullified at a given radius such as in a satellite orbiting the earth. Still not very practical. : A gravity-free environment can be attained for small periods of time such as NASA's use of airplanes with acceleration towards the center of the earth. : The most practical method for individuals to obtain a gravity-free environment, however, is merely to jump. The acceleration of your body towards the earth nullifies gravity. : If you need sufficient time to get used to the environment, you might consider Bungee Jumping or parachuting. Diving into water does not afford enough time to experience the lack of gravity. : However, the safest method with the best experience, if only for brief moments, is to swing on a swing set until the swing is almost horizontal at each end of the swing. You will experience the nullification of gravity with your stomach.

Rich:

I think you misunderstood me when I said "nullify gravity". What I meant was, some sort of apparatus that one could wear or something like that, electronic equipment, whatever, that could nullify gravity within a given radius from the anti-grav unit. Swinging on swings is not what I had in mind. I mean something that interacts with gravity on a more fundamental level, like say gravitons or something like that (depending on what you believe causes gravity)

Thanks,

Mav.
