A Planck-scale limit on spacetime fuzziness and stochastic Lorentz invariance violation
Abstract
Gamma-ray bursts can be used to test for the presence of spacetime foam—postulated in theories of quantum gravity. Quantum fluctuations would cause the photon speeds to vary, leading to 'fuzziness' and, consequently, Lorentz invariance violation.
