Fair enough, but understanding why something happens is surely within the scope of science. I get the predictions are the primary goal, but that's a lot easier if you understand why. For example, Einstein told us why gravity happens. That made it much easier to predict the orbit of Mercury.The problem with that complaint is that "What will happen if [...]?" is what physics is good at answering, but "Why does [...] happen?" is really beyond the scope of the field.
