STR or GTR is a THEORY. It may not even be true. There are other ways to interpret the question. We could easily understand, say, radioactivity in a practical sense without STR. We might have another theory instead, or else Poincare and Lorentz would have jointly got the credit. It's like asking where we would be if Columbus hadn't discovered America. Maybe the question needs reformulating: what everyday practical things contain STR or GTR. That should include reactors, radioactivity (medical and otherwise) and probably even the cathode-ray tube on our televisions (and computer terminals).
