The Basics of Special Relativity Remain Unchanged: It is Merely a Conceptual Modification of the Mass–Energy Equivalence Equation

Abstract

In the year 1905, Einstein first proposed the land marking special theory of relativity. At the time, few understood it, and even fewer believed in it. 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 chapter will revise the mass – energy equivalence equation with some conceptual modifications in the lights of particle – antiparticle pair production and annihilation. The basics of the theory of special relativity are kept intact as exactly the same but the conceptual modifications are arranged to justify the conclusion. It was indeed a remarkable year was 1905 in physics and astronomy when Einstein first proposed the special theory of relativity. This theory is the foundation of modern astronomy and astrophysics. This theory was also the foundation of the theory of general relativity proposed by Einstein in 1915 to incorporate gravity into the system. Thus, the special theory of relativity already became of supreme importance in physics since the beginning of nineteenth century and it continues to be the right from the word go theory in modern physics. An attempt is made in this chapter for a deliberate and comprehensive derivation from an equation of the special theory of relativity. The derivation is made with an aim to look deep inside of the theory of special relativity to conclude a comprehensive conclusion. Also some conceptual modifications are arranged to justify the conclusion. The physical time, mass and velocity are related in some equations in this chapter.
