The Creation Law: the Periodical Contrary Principle to Develop New Theory That Enlightens the Existence Structure to Prove & Simulate Ufos

This book is a result of 37 years of self attended research in the fields of Physics, Religions, and a study of human society's history to find out the reality of UFOs. The early result of this research reached the point where we can't believe it unless we capture one of these UFOs or build one!UFOs have no rockets or jet engines as the witnesses say, it has an engine that uses gravity repelling which is more advanced than our knowledge. If that's true, then we must restudy gravity. Restudying the Universe's structure based on the Periodical Contrary Principle (everything must have an opposite), may lead to new approaches, new understanding, and provide new technology.
