What are the consequences for this breakage? The article says current models do not easily fit the asymmetry but does not state what parts of our understanding will break if those models are wrong.
If the models are really wrong in a fundamental way and this can't be fixed by some tweaks in the free parameters (and this is a BIG if), then it's hard to predict what the consequences might be: the model is wrong, in a way that hasn't been extensively studied. How different a correct model might be is hard to predict.
