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.

Raaid Mustafa is Iraqi citizen livening in the U.S. since 1996. He specialized in electronics. After graduation he joined Iraqi Oil Tankers as an officer; traveled round the world and visited many countries. He studied Physics which he had always been captivated with.

        Space, Stars & Astrophysics studies fascinated him since his early childhood.  He couldn’t believe the stories about UFOs. “Every thing starts simple”, he says. “The best way to prove UFOs reality is to simulate it”.

         Soon he found out that simulating  UFOs was not an easy job. Raaid believes flying Saucers use gravity as there mode of propulsion.

         Raaid came to realize that in order to understand UFOs technology he would have to restudy the Universe’s structure.

      The idea that everything in the Universe has an opposite or is composed of opposites has proven to be a very helpful hypothesis to me. It led me to the discovery of what I call The Periodical Contrary Principle, the transference of this idea into a mathematical formula. Through the application of this principle, I have been able to construct a prototype of a hovering machine. 

      Earth has gravity, but it has two polarities: North and South Magnetic poles. Why is gravity considered as an attraction force only sense repelling can also occur between two similar polarities? What if we managed to recalculate gravity as a repelling force by a method that can keep the same ratio as the attraction calculations do with the gravitational force at surface between Earth & Moon? This would be an addition to our understanding of Gravity, and possibly many other cosmic factors as well.

           Another common cosmic factor is the Sphere. The Sphere has the smallest surface area compared with any other three-dimensional shape with equal volume.  For reasons that will be amply explained later, this is why the Hovering Machine or Flying Disc as can be called must be a sector of a sphere.

       The New Law of Gravity based on the repelling force (using different units of measurement) does not clash with Newton’s Law of Gravity. As a coin have two faces, so does the Law of Gravity. With my whole new way of looking at, and working with, gravity, the spherical shape and certain water specifications, I can produce and navigate the new design of a ship in deep space. Once we new the reason behind our creation, humans will feel regret and sadness. When they reach the final stage of science, they will discover that education takes the human happiness away. The reason is we born to live and die, then will born again and so on recreation will never end, only if God wish to! Human body has a soul, exactly similar to the Universe. Any thing will be turned into its shadow opposite, then the shadow will stay in shade till the other cycle starts. Our existence is a joint between the mass of any thing and the shadow of that mass, Like living human.

     This is neither an Antigravity nor Free Energy research, because such terms can’t exist; but it’s a study in the Universal Structure to review and polish the present scientific laws by the judgment of the Periodical Contrary Principle–PCP
