Abstract

It has been shown that Lorentz-like transformations with an invariant speed can be derived based on the homogeneity and isotropy of space and time and the principle of relativity. However, since the transformations can be Lorentzian or Galilean, depending on whether the invariant speed is finite, a real connection has not been established between the transformations and special relativity. In this paper, I present an argument supporting the finiteness of the invariant speed in the Lorentz-like transformations. The new analysis suggests that special relativity can indeed be derived based not on the particular light postulate but on the universal properties of space and time.
