Scientists from the OPERA experiment at INFN's Gran Sasso National Laboratory have announced the first direct observation of a neutrino transforming from one type into another. When confirmed by a few more such events, this observation will provide further strong evidence that neutrinos have mass, a phenomenon that remains unexplained by physicists' recipe for understanding the universe, the Standard Model.

We argue that a hidden assumption underlies this lore : that the scale of gravitational physics , M_g , e.g . the string scale , M_s , in string theory is of order the Planck mass , M_p 10^18 GeV . We explore sensitivity to this assumption using
