In the proposed alternative interpretation, relativistic changes occur only in association with physical interactions, and are direct alterations in the. The sun for example, being heavy, bends space time enormously. It is perhaps a little unfortunate that the word relativity immediately conjures up thoughts about the work of einstein.

Einsteins theory of general relativity predicted that the space time around earth would be not only warped but also twisted by the planets rotation. A worldline is the history of an object in space time. One of the most interesting aspects of relativity theory for the philosophicalminded consists in the fact that it gave new and surprising insights into the nature of time, of that mysterious and seemingly self contradictory 1 being which, on the other hand, seems to form the basis of the worlds and our own existence.

It is possible that progress can be made with rather different approaches covariant stochastic equations, in particular but the results to date are not encouraging. Nevertheless, even in such cases, minkowski space is still a good description of an infinitesimally small region surrounding any point barring gravitational singularities. Special relativity is most naturally formulated as a theory of spacetime geometry, but within the spacetime framework probability appears to be a purely epistemic notion.
