If speculative ideas can not be tested, they're not science; they don't even rise to the level of being wrong.
Wolfgang PauliThe natural scientist is concerned with a particular kind of phenomena ... he has to confine himself to that which is reproducible ... I do not claim that the reproducible by itself is more important than the unique. But I do claim that the unique exceeds the treatment by scientific method. Indeed it is the aim of this method to find and test natural laws.
Wolfgang PauliFor quite a while I have set for myself the rule if a theoretician says 'universal' it just means pure nonsense.
