These hypotheses need a large number of experiments, applications, and analyze the use of specialists in physics, technology, technology, engine engineers, and others, and the correct results will cause a major revolution in the field of space technology, and this theory will be relied upon in many means of land, air, and space transportation and different fields.展开更多
