The term reference frame carries within itself a huge bias in relativistic physics, and explains all by itself all the problems that will arise in the history of modern aphysics.
At the beginning, in the time of Newton and Descartes, there was no problem using this term, because we did not go too far, and
above all, because we did not travel very fast.
Today, telescopes see very far, much better (apparent speeds of supernovae extensions), and above all, electrons and protons go very fast in particle accelerators.
The word reference frame then becomes a dubious term, because if at the beginning, we could represent a reference frame as four axes perpendicular to each other, we know today from Dr. Hachel, that this notion is no longer possible because of the time component. It is no longer possible to conceive of the universe as a vast four-dimensional hypervolume, since each point of the universe that composes it is at the base (at the origin O) of its own hypervolume (because of the time component).
Thus, if the term "stationary frame" remains correct, the term referential
is only correct if we admit that we are talking about the referential centered on a single object, and that a simple little metric translation from wherever it starts destroys the referential to create another one.
