When a theory is based on evidence, then all it really is is an abstraction of said evidence. So unless the evidence is overturned, the theory still stands as accurately as it had since inception.<p>What QM has is better accuracy and a different scope. It solves different problems, and where it overlaps, it does better. Also, it is not an extension of Newtonian physics, and hence is a new paradigm. It is not a better version of Newtonian physics.<p>I disagree that multiple paradigms describe the exact same things with respect to paradigm shifting science. They are merely different models, and are not new paradigms in the Khun sense. In fact, the fact that they are not pushing science forward attests to this. There are versions of reality because we are uncertain. Not because each is a different way of thinking that solves new kinds of problems.
