Pardon the silly question, but what is the actual meaning of "right" and "wrong" in physics? I would expect a model which works in all possible conditions to be right, but clasical physics breaks when you reach the speed of light or atom level scales. Also, my intuition tells me that there can't be two completly different models that are describing the same thing and both of them are right, but we have e.g. definition of light as EMV and as a stream of particles. So it's enough for physical model to work only in specified conditions to be considered right, but "Basic Assumptions of Modern Physics" must be ultimately right (must work in all possible conditions)?
