Anti-gravity is a kind of gravity in which one object is repelled by another. Neither Newton's nor Einstein's gravitational theory ruled out the existence of negative mass, which ruled out ordinary (positive) mass. The concept of anti-gravity is based on the assumption of negative mass. Until 1968, no one has reported and observed the evidence supporting this view.
Newton first discovered the gravity of the earth and put forward the law of universal gravitation, which contributed immeasurably to human civilization. It is true that we all know gravity, but few people think of anti-gravity.
This term has been mentioned as early as Einstein's theory of relativity, and it ranks fourth among the "eight challenges of the future of mankind" listed by Future Scientists. Today, the anti-gravity technology has been successfully broken through by the inventor in China, and the invention patent (891911) has been successfully obtained in the United States.
Anti-gravity technology is to obtain energy from gravity field and realize propellant-free driving. This invention is based on Einstein's prediction of gravitational waves. Gravitational wave is a gravitational field with waveform and finite speed propagation. Gravitational waves are related to the choice of coordinates. There may be energy in one reference frame, but there may be no energy in another reference frame.
On the basis of gravitational waves, scientists combined Pascal's law 300 years ago: the pressure in liquid is transmitted equally in all directions, that is, the energy of liquid pressure doing work in any direction is conserved. Therefore, people have designed hydraulic systems and submarines (submersibles) that can overcome gravity suspension. When these two pressures act on the submersible at the same time, we can rely on the energy conservation of external pressure to realize the anti-gravity work of the submersible.
In a word, the internal energy of liquid is obtained by gravity conversion of the earth, and then electric energy is successfully generated by shaft torque.
