Can anti gravity be realized

Is anti gravity technology possible?Anti gravity technology is possible. In the past few decades, many scientists have studied anti gravity, but at present, all experiments do not support the existence of anti gravity. However, thanks to tireless efforts, this technology is just around the corner.The basic principle of anti gravity technology is to rely on the reverse gravitational field formed by the machine itself to offset or block the gravitational field of the external environment to obtain thrust.Basic introductionNewton was the first to discover the gravity of the earth and put forward the law of universal gravitation. The contribution of this discovery to human civilization is immeasurable. Admittedly, we all know about gravity, but few people think about anti gravity. This term was mentioned in Einstein's Theory of Relativity as early as, and it ranked fourth among the eight future challenges of mankind listed in The Future Scientist.Anti gravity technology is to obtain energy from gravity field and realize propellant free drivingTesla has tried to design "anti gravity aircraft", can it be realized? What are the technical difficulties_ Baidu ZhiAfter the development of science and technology, people immersed in the past immortal system gradually saw the truth of the world, and found that the gods did not exist, and the universe was far wider than we imagined.Up to now, it is obvious that humans have rarely believed in the immortal Buddha, but at the same time, with the deepening of the exploration of the space field, people believe that there must be mysterious aliens living in the outer space.Since the 19th century, people in various countries have repeatedly said that they have encountered aliens. Because people at that time did not have such highly developed and convenient photographic equipment, most people only gave relevant oral "evidence".Before the 20th century, more than 300 complete UFOs, known as UFOs, were found all over the world. In the 20th century, especially after the 1940s, more and more UFOs were witnessed in the worldCan anti gravity technology be realized?I believe it can be achieved. In the future, it can be used to drive motor vehicles, so that no fuel is needed.Can human beings master the anti gravity technology? If so, what will happen?With the development of science and technology, human beings will also master the anti gravity technology in the near future. Once they master this technology, they can live in the air.Is anti gravity technology possible?impossible.Newton was the first to discover the gravity of the earth and put forward the law of universal gravitation, which contributed immeasurably to human civilization. Admittedly, we all know about gravity, but few people think about anti gravity.This term was mentioned in Einstein's Theory of Relativity as early as, and it also ranked the fourth among the "eight challenges in the future of mankind" listed in "Future Scientists". Today, the anti gravity technology has been successfully broken through by Chinese inventors and successfully obtained the American invention patent (8919111).Anti gravity technology is to obtain energy from gravity field and realize propellant free driving. The invention is based on Einstein's prediction about gravitational waves. Gravitational wave is a gravitational field with wave form and finite velocity propagation. Gravitational waves are related to the selection of coordinates,
