Abstract This chapter examines several locality conditions. It argues that two of these principles are irreducibly causal: the principle that all causal propagation takes place at a finite velocity of which relativistic locality is a special case, and spatiotemporal locality, according to which no causal influences can be transmitted across spatiotemporal ‘gaps’. Neither of the two causal principles can be reduced to the noncausal condition of diachronic locality.

In 1905 A. Einstein, from the experiments of Michelson and Morley in 1887, enunciates the light speed constancy principle in the inertial frames of reference. However, this principle was pointed by the equations of the electromagnetism of J. C. Maxwell in 1865. The prediction of the Maxwell equations is due to in the most basic principle of the science, the principle of causality, is the reason of the light speed constancy. This article shown how, only with the causality principle, we can deduce the properties of the light. At the end of the article we used the causality relativistic definition to approach the local action principle, as well as to solve the paradox that implies the EPR theorem.
