Was Einstein really the first to invent Theory of Relativity?
Even if some one else claims to invent theory of relativity earlier…they cudnt prove it as Einstein did… Theory of relativity : The theory of relativity , or simply relativity, refers specifically to two theories of Albert Einstein: special relativity and general relativity. However, “relativity” can also refer to Galilean relativity. The term “theory of relativity” was coined by Max Planck in 1908 to emphasize how special relativity (and later, general relativity) uses the principle of relativity. General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: In other words an object in free fall is falling because that is how objects move when there is n
