"In general relativity, space and time are woven together into a pliable thing called spacetime, but quantum mechanics runs on quaintly separate, classical notions of space and time. And when physicists try to apply the equations of general relativity to the realm of quantum mechanics, those equations spit out nonsense." http://fqxi.org/community/articles/display/224

"The concepts of time (spacetime) in quantum theory and GR are thus drastically different and cannot both be fundamentally true." http://hindawi.com/journals/isrn/2013/509316/

So what? In Einstein's schizophrenic world lie and truth harmoniously coexist, like 2+2=5 and 2+2=4 in Big Brother's world (and the lie is "always one leap ahead of the truth"):

George Orwell: "In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?"
