Some things in nature are misleading. We do have a theory of relativistic QM, and it is functioning quite well. We have not reconciled our theory of gravity (general relativity) and QM, and that is an area that a number of theorists are working in. Scientific American had an earlier article on this. While, alas, they count as a professional physics publication no more than Nature, they did give perspectives of a non-proponent: <quote> For now, these ideas are barely more than scribbles on the back of an envelope, and critics have myriad complaints about their plausibility. For example, how exactly would matter or spacetime change state during the collapse of a star? Physicist Scott A. Hughes of the Massachusetts Institute of Technology says, "I don't see how something like a massive star--an object made out of normal fluid, with fairly simple density and pressure relations--can make a transition into something with as bizarre a structure as a gravastar." Mainstream theories of quantum gravity are far better developed. String theory, for one, appears to explain away the paradoxes of black holes without abandoning either event horizons or relativity. <end quote> So, the odds are against this being validated. But, if we do see gravity waves, we could look for unique types of gravity waves predicted by this theory.
