The theory of relativism in the theory of physics is a theory of relativism. This theory initiated a new era in the physics world. Albert Einstein, the founder of this theory. According to the theory, space, time, and matter or mass are nothing but absolute. Scientists Einstein started this theory in 1905 with the introduction of special theory of relativity. Based on the significance of these two important discoveries, the beginning of the nuclear era begins, in relation to the relativity of the mass and the conversion of the mass into energy.
Relativity
According to classical mechanics, space, time, and matter or mass constants are not relative. Einstein said that space, time, and mass or mass are not constant or absolute, these are relatively relative. This theory of Einstein is called a relativistic theory.
Special theory of relativity> postulates of special theory of relativity
First admit: The physics sources are the same in all the inertial framework
The second point: "One is the speed of light in all the inert structures in the void."

What a tautological diaster that first sentence.
