Is it possible to produce zero gravity condition on earth. It is possible for a freely falling system. But is it possible in a static system? Can we sort of " insulate" against gravity?
Dear Mir,
I think in the following way: if one mass/energy produces a deformation in space-time and another mass/energy produces another deformation, if we manage to join them with some kind of force not dependent on that space-time, it is possible that in the Intermediate point space-time will suffer a deformation in the opposite direction, and can reach gravity 0 and even antigravity.
Dear Mir Aamir,
Yes,
In 2007 I have written an article: Planet-erosion (Hungarian)… It exists a poorly made translation:
http://planeterosion.blogspot.com/
But in 2009 I have made the article where explains: how the variation of gravity can permit this:

And in this year another article an extended of an article published in 2009:

Yes you can... Magnetic levitation uses in Maglev Train is just one example... Other way using superconductivity....
Dear Gokaran,
In nature we observe such a situation: in case of capillary action…
Dear Gokaran Shukla,
Thanks for the answer. Magnetic levitation is fine for magnetic materials. But suppose we want to train astronauts for zero gravity environment, how can it be done? I was thinking of some means to prevent gravity from acting on the body rather than counteracting it.
Dear Mir,
MA : "I was thinking of some means to prevent gravity from acting on the body rather than counteracting it."
GS: Gravity is the consequence of linear mode of space vibration due to the source called MASS....If you want to kill gravity, you have to kill mass first... Because, as long as mass exist, gravity will exist.... Its like, as long as you breath, you will be alive.... So, gravity can not be prevented.. It can only be counter balanced, as it has been done in many experiments, like Stokes rule for terminal velocity in viscous media, measurement of charge, measurement of angular speed of earth about it geometrical axis.......
I think there is a bit of confusion in this issue, in space there is no gravity 0 (except perhaps in Lagrange points) when an object is in orbit what it is doing is to "fall" continuously, but there is no gravity 0.
Nor would there be gravity 0 even if a magnetic field were applied to levitate objects.
Sorry, I think I misunderstood the question, the question was how to get a gravity 0 "simulated"
Hi Sergio Garcia Chimeno. Thanks for your answer. The question is whether it is possible to create an enclosure (or something similar) within which gravity would not act. The enclosure sort of keeps out gravity from entering the space.
You can simulate zero gravity for a person within an enclosure during free fall. Essentially, though, you are creating a pseudo zero gravity environment for short periods of time. The experience of zero gravity in a spacecraft is achieved when rotational velocity is properly synchronized with altitude. Centripetal force, here, neutralizes the free-fall component. But the fact is that as long as any matter exists in the universe, some aspect of gravitational influence, albeit very small, will always exist.
Near-weightless environments on Earth are employed to train astronauts. It can be achieved on an aircraft, for example (https://en.wikipedia.org/wiki/Reduced-gravity_aircraft). Stephen Hawking enjoyed a trip on that type of aircraft and felt very good!
Astronauts are also trained in a static system, just a pool with water.
If you really want to "insulate against gravity", have a look at Muhammad Ahsan's question:

I would say the same that I said there.
