Antigravity will be the greatest thing. That we have ever created.

"Artistic depiction of a fictional anti-gravity vehicle" (Wikipedia, Anti-gravity)

Sometimes, if the airships have the same lifting power as the weight of the airship.  It can act like some “antigravity system”. Those systems are based on lighter-than-air gas or hot air. The system can have a helium tank. And the hot-air section whose temperature can be adjusted using microwaves or particles that lasers warm. Those systems are faster to control than some gas flames. This makes it possible. To adjust the lifting power. 

If a thing like a balloon has the same lifting power as its weight, the balloon can be lifted to a certain point and altitude. And the balloon stands at that point until something moves it. That kind of thing can make an impression. On the antigravity systems. Modern airships. Like Lockheed-Martin P-791 can look. Like a “UFO”. The system can use systems to move the craft. Or maybe those ion systems are used for plasma stealth systems, if those airships' mission is to observe the ground in a military area. It’s possible that those systems can also collect crashed, highly secretive, recon planes and fighters from the area. And in that case, those systems must fly silently and stealthily. 

But then to anti-gravity. 

“Antigravity refers to a theoretical concept of a novel force that could counteract the effects of gravity, potentially allowing for new forms of mechanical transport. It is often associated with terms such as electro-gravitics and field propulsion, though these remain speculative and not yet realized in engineering practices.” (ScienceDirect, Antigravity)

There are theoretical models of what antigravity could be. But those models require more advanced materials. And advanced systems that can turn this into reality. Antigravity is normally misunderstood. As the electro-gravity and field propulsion. They normally use things like ion whirls to hover the craft. The antigravity means that the system manipulates gravitational fields and denies their interactions. 

Maybe someday, antigravity is possible. Antigravity is theoretically. A very easy thing to make. The system must “only” make the gravity pothole in the craft, and that gravity pothole, which is against the gravitational center. Can deny the gravitational interaction between the craft and the main gravity center. The system is based on the gravitational counterwaves. If some system can create gravitational counterwaves. That can deny the gravitational interaction between the craft and its environment. Simply saying, an anti-gravity system must cut the gravitational channel between the craft and the ground, or the main gravity center. 

"A high-temperature superconductor levitating above a magnet. Persistent electric current flows on the surface of the superconductor, acting to exclude the magnetic field of the magnet (Meissner effect). This current effectively forms an electromagnet that repels the magnet." (Wikipedia, Superconductivity)

Superconductivity and other electromagnetic phenomena can also levitate craft. They may look like real antigravity. But in those cases, electromagnetic phenomena. Causes levitation. That case means that there is a possibility that the metal ball that surrounds the capsule will freeze at the superconducting temperature. That superconducting structure can explain why things like “metal ball” UFOs can hover, and why there are no IR or other kinds of signatures. Superconductivity requires a very low temperature. And that can explain why those things behave like they do. 

The model of an antigravity spacecraft. The system requires so much energy. That it can remain at a theoretical level. 

Lockheed-Martin P-791 experimental airship. 

The system must create an artificial black hole or a neutron star inside it. If we had an artificial neutron star. And we put it in the air, so that the supermassive structure can hover in the air. In the same way, if the system can make an artificial black hole and control it, the black hole puts the craft into hover. Theoretically, it is possible to create miniature neutron stars, the small neutron balls that spin very fast. 

Or the system can create an artificial black hole using two-layer fullerene balls. There can be an electron cloud between those internal fullerene structures. If there is a nano-sized iron bite in the internal fullerene, the system can press those iron atoms into a black hole. And then the system shoots positrons into that electron layer. The explosion. That looks like an implosion bomb explosion. Can symmetrically push those iron atoms into the singularity. This could be the simplest possible way to create a black hole. By pressing atoms and their electron layers and subatomic components into one form. Called a singularity. 

In that case, the structure that gravity potholes forms looks a little bit. Like the structure where two horns are opposite to each other. The gravitational pothole that the craft makes locks it above the pothole that the gravitational center forms. 

The system makes a gravitational pothole. Above the gravity pothole. That gravitational center makes. The gravitational pothole that the craft makes. Pushes the craft up from the sides of the pothole. The gravitational waves push against the edge of the other gravitational pothole.

Another way to think about the idea is that. There is a fast-spinning object in the craft. That fast-spinning structure binds energy inside it. The fast-spinning structure harnesses energy that it binds from the environment. This makes energy travel to that center through the craft’s surface. Energy that travels to the craft locks it into its position. So, the energy that this structure binds puts our “antigravity craft hover”. The thing that puts our hypothetical craft move is the system that adjusts the energy symmetry in the craft’s body. 

If researchers want to create the gravity center, they can use the ball. Which has many layers. Those layers can spin in opposite directions. And the system injects energy into them. The internal structures of that multi-layer ball harness and binds so much energy that it turns into a black hole or the gravitational center that can raise the craft to hover. 

The energy can be pumped into the ball. Using electromagnetic systems or some kind of particle accelerators. The idea is that the system creates. Such a heavy mass. In the craft. That makes a gravity pothole that denies. The gravitational interaction between the craft and the environment. This system requires the gravity center, which is used to harness energy or create the gravity porthole. This means turning that theory into reality. It is not a very easy thing.  But it's not impossible.
