Yes, that's true, however, that's what they've been doing all along when they find something that doesn't fit in with their current SM. They tweak everything in order to make it fit. Or they don't explain it at all. Or if they're good at it, they manage to predict another new particle that fits. That's what I said originally, or at least implied in my last post. What happens if this dark matter they think they've found doesn't fit in with the SM, which is just as likely as it is fitting in. Going to be hard trying to explain something that lies completely outside of the SM. Means the SM isn't standard, does it
It's having no luck with gravity, nor with neutrinos (why they may have mass). And, what the hell happens if they don't find the Higgs, at all. Considering that the SM predicts the existence of the Higgs, having one of its "feature" particles not appearing at all is going to be a tad embarrassing
But, let's see what happens with the LHC.
What it all means, is that the SM is far from complete and it's probably not even the best theory from explaining all the possible particles and interactions as it presently is.
