Covariance and Frames of Reference

A transition of focus from state space to frames of reference and their transformations is argued as being the appropriate setup for ensuring the covariance of physical laws. Such an approach can not only simplify and clarify aspects of General Relativity, but can possibly help in the development of a Grand Unified Theory as well. " Physics may be not only too important, but also too deep, in order to be left alone to usual physical type thinking and arguments. " 1. Frames of Reference versus State Space 1.1. State Spaces Classical. At least since H Poincaré, we are accustomed to associate with the dynamics of a given physical system a corresponding state space which is the set of all possible points, each of which uniquely describing one of the possible situations the respective system can be. Consequently, a state space can be finite or infinite dimensional.
