Einstein's theories may not be the whole story

A STORY over at NYU's Scienceline site tells of possible findings that Einstein's theories of relativity may not hold for the universe at large. Apparently some older data on how certain galaxy clusters formed didn't match up with what Einstein's General Relativity predicts, though the findings have yet to be confirmed. If they do however, it seems that in certain places in the universe objects may not act according to gravity!
