OTOH, there are theories which fit the existing facts well, and there are
theories that don't.  As you say, a theory isn't the ultimate truth of the
universe; the facts which the theory explains are.  When a new theory is
proposed, it must explain all of the facts that the old theory explained
before it is considered to be as good; so any theory proposed as a
replacement to Special Relativity must explain why objects moving at speeds
comparable to that of light are more massive and longer-lasting - both
experimental facts.
