A number of researchers believe that there is now a crisis in fundamental theoretical physics.* Scientific pluralism** is one way to combat such problems. It is less likely that the development of various alternative models of reality will all stagnate at the same time. One can also use experiments like A.s.a. H. to try to formulate completely new physical concepts.***
