I'll assume you mean 'defy'.

I don't think it's possible right now. That is, I don't think scientists and researchers know enough about gravity to be able to manipulate it. Remember, of all the properties or parameters in nature (such as the speed of light in a vacuum, the force of an electron, the mass of a charm quark, etc), gravity is the least understood and least accurately measured property.

Like PhysicsDude said, you can only counteract it's force (e.g., exert a force equal and opposite the direction of gravitational pull).

Now, I'll assume you really meant 'how do you 'deify' gravity'? Actually, I think that gravity is already 'of a divine rank'. That is: the nature of gravity is un-understandable (at the present level of knowledge, anyway).

Defy gravity--right? I agree with those who said that gravity has its effect even in a vacuum.

There is no shield against gravity. Even the shield will start sucking you toward it. The inside of your body is pulling (very slightly) the outside in (I wish it worked better for my gut, but that's another whole discussion).

I do not agree with the answerers who said that either free-falling or orbiting (that's essentially free-falling at a billion dollars a ride) are "gravity-free." Hey, dude, you're accelerating under the force of gravity. How is that "defying" gravity?

Probably the the closest you can come to "defying" gravity is to find one of those cool zones where opposing masses are essentially cancelling out each other's gravity--sometimes referred to as Lagrange points. There are five of them between Earth and the Sun, and others here and there in space.

Interestingly, there are satellites sitting in a few of these zones. The link (to a NASA site) has a map showing the 5 Earth-Sun Lagrange points. Happy gravity-free floating!

Like they deified Augustus. Just have the Roman senate to declare gravity a god and have a temple built in honor of it. Now if you want to also defy the gravity, that is something much harder.

Deify: gravity is the only force of this universe which can touch another universe

Defy: lift a finger

Do you really mean deify? or did you mean defy gravity?

Assuming you meant how do you defy gravity, then the answer is that you must exert a force equal and opposite the direction of gravitational pull. So for example, here on planet Earth, at sea level, it would require you to accelerate upwards at 9.8 meters per second per second in order to simulate freefall.

PS - Gravity is felt whether it is in vacuum or not. It makes no difference. So if we were on the Moon's surface (which has no atmosphere hence it is a vacuum), then you would need to accelerate upwards at 0.82 meters per second per second to nullify Moon's gravitational effects (the Moon's gravity is 1/12 of Earth's).

Actually it is impossible to defy gravity, because no matter how far you travel from an object, it is always exerting a pull on you. The smaller and farther away an object is, the smaller it's pull, even to the point where it is nearly negligible, but it is always there.

i think u mean defy gravity.....there is no effect of gravity only in vacuum...where there is no air or no medium for that case....gravity is a force that pulls u towards the center of ne planet or stars....etc.....depending on their mass the gravitational force also varies....u defy gravity when ur mass = 0......n tat is possible only in vacuum....so its not possible to defy gravity on Earth or other planets...only in space.....i hope i made myself clear....:)

I defy gravity in my dreams! I have actually learnt to fly like Peter Pan now!
It's fun, and you should try it!
In your dreams!

Get in to an airplane, ask the pilot to do a 45 degree dive, and you'll float.

try SCUBA diving- you can float and 'fly' at any height above the sea floor- amazing sensation =D

liked the comment about the bra- that sounds pretty good too lol
