Problem
Someone argues: "The rotating relativistic string gives J=α′E2, which matches the slope 0.92GeV−2 fitted to the ρ family exactly, so hadrons must literally be made of one-dimensional strings. Since the quantised closed string necessarily contains a massless spin-two state, the graviton, string theory has therefore been experimentally confirmed as the correct quantum theory of gravity." Find the errors in this reasoning.
