A Conceptual Framework for Understanding Faster-Than-Light Neutrinos
  Recent experiments have led to the production of neutrinos with transit times indicating the appearance of traveling faster than the speed of light. In this paper, we present a conceptual framework to understand how faster-than-light events involving neutrinos (as indicated by time-of-flight) might occur. We propose that observations of this kind do not violate the special theory of relativity; instead, they only help to provide evidence in support of the general theory of relativity at quantum scales. Given the relativistic effects of the neutrino on its local spacetime environment, the measured time-of-flight at the macroscopic level is attributable to a decrease in the effective path length traversed by the neutrino. Specifically, along preferred directions, we show that the Kerr metric allows for the compression of spacetime; hence, the decreased path length hypothesis is plausible. Furthermore, when the motion of the neutrino is along the preferred direction for spacetime compression, the Kerr metric also predicts strong frame dragging effects near the Planck length. In the region where strong frame dragging occurs, we propose that the microscopic explanation for the path length compression is due to the formation of 'micro-wormholes' near the Planck length.
