Basics of the special relativity are kept as exactly the same: It is just conceptual modification of mass-energy equivalence equation

In 1905, Einstein first proposed the special theory of relativity. That time, very few understood it and even fewer believed in this theory. It was until 1919, when first experiment was carried out on the general theory of relativity which actually proved the special theory of relativity by some inferences of the experiment. This paper will revise Einstein’s mass – energy equivalence equation E = mC2 with some conceptual modifications in the lights of particle – antiparticle pair production and annihilation to modify the equation into E = 2mC2. The basics of the special relativity are kept intact as exactly the same but the conceptual modifications are arranged to justify the conclusion. Also I will focus on concepts of transitional masses, the space – time and parallel Universes briefly.In 1905, Einstein first proposed the special theory of relativity.
