Einstein had a more specific objection to quantum mechanics. According to the theory, particles can become paired such that an impact on one of them can instantaneously affect the other, no matter how far apart the particles are. Einstein argued that this was impossible, because information could not travel between the two particles faster than the speed of light. (He dismissed this aspect of quantum mechanics as ?spooky action at a distance.?) In other words, he thought it violated the special theory of relativity, just like those neutrinos were supposed to have done at CERN in September. In this case, experiments have proven Einstein wrong?distant particles do seem capable of reacting to each other simultaneously. However, most physicists say the phenomenon doesn?t really violate Einstein?s special theory of relativity (PDF). They claim that, in certain cases, space isn?t enough to break an intrinsic connection between particles. (If you find this impossible to understand, take the advice of physicist Richard Feynman, who famously counseled his listeners, ?Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain', into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.?)
