This book is a research work. It is an established fact that the earth moves in space and velocity of light measured on earth is c. Therefore velocity of light with reference to a frame at rest relative to vacuum is calculated as c+v on earth. Analysis of Michelson-Morley experiment with reference to a frame at rest relative to vacuum giving the null result confirms this.
It is discovered that Einstein made a mistake in his thought experiment regarding simultaneity. That resulted in error in measurements of velocity and therefore in length and time. Thereby it is established that there is no relativity of time, but instead time is constant across all frames.
By using correct classical methodology, it is demonstrated that stationary frame can be identified with certainty when there are only two frames in vacuum and are treated within the framework of principle of relativity. That suggests a preferred frame of reference within relativity classifying it as a subset of classical methodology.
