""Russian Troika" as the New Spatio-Temporal Paradigm"
It is proved that the (local) causal structure of the (flat) Minkowski space-time M can be (metrically) defined by each of the three (curved) worlds D, F, L (and there are no other options to represent M in such a way). D, F, L are (the most symmetric) general relativistic space-times. They are supposed to substitute M (like a hundred years ago the Newtonian world had to give up its leading role when M emerged). It is argued that a description of a physical system is inevitably incomplete without taking the new F-, and L-energies into consideration (whereas the D-energy is the standard one).
