WebMar 23, 2024 · There exist two physical postulates of special relativity from which everything else follows as a consequence. These are: (1) the constancy of the speed of light in vacuum and (2) the form invariance of physical laws in all inertial frames. Every textbook lists out these two postulates and derives everything from them. In physics, Albert Einstein's 1905 theory of special relativity is derived from first principles now called the postulates of special relativity. Einstein's formulation is said to only require two postulates, though his derivation implies a few more assumptions. The idea that special relativity depended only on two postulates, … See more 1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference. 2. Second postulate (invariance of c) As measured in any inertial frame of reference, light is … See more Without a "bridging hypothesis" as a third postulate, the 1905 derivation is open to the criticism that its derived relationships may only apply in vacuo, that is, in the absence of matter. The controversial suggestion that the 1905 theory, derived by … See more In the rigorous mathematical formulation of special relativity, we suppose that the universe exists on a four-dimensional spacetime M. Individual points in spacetime are … See more Historically, Hendrik Lorentz and Henri Poincaré (1892–1905) derived the Lorentz transformation from Maxwell's equations, which served to … See more Einstein's 1905 derivation is not complete. A break in Einstein's logic occurs where, after having established "the law of the constancy of the speed of light" for empty space, he invokes … See more Einstein's special theory is not the only theory that combines a form of lightspeed constancy with the relativity principle. A theory along the lines of that proposed by Heinrich Hertz (in 1890) allows for light to be fully dragged by all objects, giving local c-constancy for all … See more
