'Theory of everything' tying researchers up in knots

The most celebrated theory in modern physics faces increasing attacks from skeptics who fear it has lured a generation of researchers down an intellectual dead end.
...Already, the split over string theory has caused tensions at some of the nation's university physics departments. "The physics department at Stanford effectively fissioned over this issue," said Laughlin, now on sabbatical in South Korea. "I think string theory is textbook 'post-modernism' (and) fueled by irresponsible expenditures of money."
