Deduction of Lorentz Transformation from the existence of absolute rest. Deduction of the speed of light in any frame of reference

摘要

We begin by admitting the following: (i) there is a frame of reference wherethe speed of light is the same in any direction (that speed is c) (ii) theaverage speed of light on a two-way journey is c in every frame of reference. From this two premises we obtain an expression for the speed of light whichimplies the speed of light depends on the motion of the frame of reference.Also from this two premises solely we deduct Lorentz Transformation.
