Every object in the universe attracts every other object in the universe (and the larger the object, the more attraction there is), but if there were particles that repelled every other particles in the universe, maybe we could search for them at the end of space (and time?).


My point is, why do objects attract each other? What is gravity? How does it exist? And if we understood this, then maybe we could "reverse" the polarity of the attraction, and make objects "naturally" repel each other? The problem is, the particles would just disappear into space....

Anyway, is it possible to reverse gravity, and make anti gravity devices? (apart from the cat and toast idea)

Two bodies both having mass (the sum of the mass of all the protons, neutrons and electrons) attract each other in accordance with the inverse square law. The moon and the earth attract each other. The earth attracts you giving you weight on a measuring scale. However, you also attract the earth because you have mass. It is kind of like the kid pulling up a weed even though the entire world was holding onto it.

It would seem that to invent (or discover?) an anti-gravity device, it would be necessary to invent (or discover?) anti-mass. The fact that none has been observed in Nature is no proof that none exists. In order to prove that red seagulls exist in Nature you must discover only one (hopefully not a fake?).

If a weight on earth was composed of protons, neutrons and electrons having negative mass, it likely would have fled into space long ago. Scientists have discovered anti-matter were for example a positron will annihilate and electron and release energy but both are known to possess positive mass.

It seems unlikely as of now that an anti-gravity device will be invented or discovered (any time soon?).

They already have them. Ever heard of a trampolien? Gravity is the weakest force in the universe

I've been trying to do that, off an on, for decades. But to the best of science's current knowledge, gravity is always attractive, and can't be insulated or shielded. But there are technologies which do permit hovering, such as helicopters, hovercraft, VERTOL (vertical takeoff and landing) aircraft, and so on. We have lots of methods for counteracting the force of gravity by use of other forces.

I do belive so "Call me mad but I do" the thing is that it is possible to create an antigravity device BUT the main problem is that GRAVITY ITSELF HAS NEVER BEEN FULLY DEFINED.
Thus it remains an Enigma. People may be sceptical about the feasibility of creating and antiGravity device thus the theory of gravity remains a like of un explored area. the only devices that can break themselves loose from the clench of gravity is either by conventional methords(weaker and less dence molecues puched up), or other mechanical methords(like swimming one pushes the water molecues down thus the reactant force is raising up and up "apply it to air and rockets planes")

just a quick correction - in theory everything ISN'T possible.

Back to the question. Gravity is one of the four basic forces of nature. Unlike the electromagntic force it doesn't have an opposing forces so anti-gravity is impossible although it might be posible to be able to shield a body from gravity so that you could be in zero-g.

You are right it is natural that since some objects do attract it is natural that they also detract depending on their polarity.

Where would an antigravity device be useful for nowadays anyway? We have lots of energy to consume on other means of transport...!

Well in theory everything is possible, but to put it into practise is so far impossible. Human race might be smart but it hasn't evolved enough to understand the complexity or simplicity of the gravity and other unanswered question that we have. Give it another 200 or so years and them we might see some answers.

I've got two anti-gravity devices...and you can't have one.

nobody knows how to do that... yet

we aren't even sure about gravity waves or gravitons

Yes if you made the object lighter than air.
