Asking "why" may lead to really new physics, though. I assume the reason for discovering the theory of relativity was asking "Why is the speed of light constant

  My point is, why isn't really a question that makes sense. There isn't a "why" the speed of light is constant and isotropic. The answers you typically see for that question is just different ways of saying the same thing; there is no causal relationship. In the end, it just is. There are things that must be true if this is the case, and things that can't be true if this is the case.

    Without asking "why is the speed of light constant", you wouldn't discover the reason. The reason is that space is not just space, but space-time. There is not always as discoverable reason behind a physical phenomenon, but sometimes there is. Not asking why altogether isn't a good approach in my view. But I understand your perspective.
