Einstein's theory of gravity..... still just theory  

An interesting new observation of a ring of Galaxies, may mean we need to re-write the rules. "Bridge to Engineering, Scotty could you please change the Laws of Physics again ?"

Or there's something currently unobserved that provides for the explainaiton.

and it was just a theory - but at least he knew it was wrong.

General Relativity has been tested over and over. It also predicted black holes before any physical evidence and also dark energy. It has not been superceded.

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.

 One of the essential features that a new theory must have is "consistency". It must take into account the successes of previous models. For instance, Special Relativity coincides with Newtonian predictions at small fractions of c. The curvatures of General Relativity are consistent with Special Relativity in flat space, so Special Relativity becomes a special case of General Relativity. General Relativity might become a special case of some more subtle model, but to say that it's just wrong is crude and misleading.

To many people in this world need to remember that theory doesn't mean what they think it does. In detective work and common phrasing, theory means an educated guess with some basic logical assumptions. In science, that is a hypothesis. A theory is something that has been worked on and tested at least several times. It is not a "guess".
