It's important to take on account that almost everything (if not everything) we know in science is a theory, and as such is subject to being wrong. A model is presented and if that model can explain and accurately predict certain phenomena and be able to replicate it through experimentation then it's valid.
Therefore a model can be wrong and it shouldn't be followed blindly. Of course that a model can be proven to be certain over and over becoming a reliable basis on which support further experiments and theories, but my point is that it shouldn't surprise us when a model is defied by any new results of experimentation that contradict said model, as it is in the nature of the theory and model the chance (and probability) of it being wrong.
Just a thought that I think we should keep in mind when discussing scientific matters.
