# Epistemic Relativity: An Experimental Approach to Physics

## Abstract

The recent concept of *relativistic positioning system* (RPS) has opened the possibility of making Relativity the *general standard frame* in which to state any physical problem, theoretical or experimental. Because the velocity of propagation of the information is finite, *epistemic relativity* proposes to integrate the physicist as a truly component of every physical problem, taking into account explicitly *what* information, *when* and *where*, the physicist is able to know. This leads naturally to the concept of *relativistic stereometric system* (RSS), allowing to measure the intrinsic properties of physical systems. Together, RPSs and RSSs complete the notion of *laboratory* in general relativity, allowing to perform experiments in finite regions of any space-time. Epistemic relativity incites the development of relativity in new open directions: advanced studies in RPSs and RSSs, intrinsic characterization of gravitational fields, composition laws for them, construction of a finite-differential geometry adapted to RPSs and RSSs, covariant approximation methods, etc. Some of these directions are sketched here, and some open problems are posed.
