The method of relativists (those who believe in Einstein’s relativity) seem to be to discard concepts (such as aether, absolute frame etc), but they do not make clear the sense
of the discard, whether it is: (i)compulsory discard (in the
sense that can’t bring the concept back) or as (ii) optional
discard (in sense that can bring the concept back if feel
need to), and then they often make talking about the
discarded concept as taboo.
