The authors' main claim In particular, the model may explain the recent observations of the FERMI Gamma-Ray Telescope on delayed emission of 30 GeV photons from a distant Gamma-Ray-Burst 090510, in agreement with previous observations from the MAGIC and HESS Telescopes, but can also lead to falsifiable predictions for quantum foam effects in forthcoming upgrades of certain "particle interferometers", such as neutral meson factories.

Original abstract

Quantum Space Time may be characterized by a plethora of novel phenomena, such as Lorentz violations and non-trivial refractive indices, stochastic metric fluctuation effects leading to decoherence of quantum matter and non-commutativity of space-time coordinates. In string theory, which is one of the major approaches to quantum gravity, such coordinate non-commutativities arise naturally in many instances. In the talk I review one such instance, which arises in the modern context of D-brane defects in the background space time, over which string matter propagates. This serves as a prototype of space-time foam in this context. I chose this model, over many others, because it may actually have some unique features that can be falsified experimentally either by means of high-energy astrophysical observations or in some particle-interferometers, such as neutral meson factories. In particular, the model may explain the recent observations of the FERMI Gamma-Ray Telescope on delayed emission of 30 GeV photons from a distant Gamma-Ray-Burst 090510, in agreement with previous observations from the MAGIC and HESS Telescopes, but can also lead to falsifiable predictions for quantum foam effects in forthcoming upgrades of certain "particle interferometers", such as neutral meson factories.

  • One should add to these effects the very recent observation [ref] from the FERMI Telescope of an extremely short burst, GRB 090510, of duration of order of a second, with highest-energy photons with energies $31$ GeV, arriving at about $0.4$ sec later than lower energy photons, of energies of order 1 GeV or in the MeV range.

  • The fact that the interactions are causal is an exclusive feature of string theory, as emphasized in [ref] , and stems from the fact that the amplitude calculations lead to the existence of only retarded waves, emitted after the scattering of the open string states with the defect, and the absence of advanced waves that could cause violations of causality, which by the way do characterize local field theories in non-commutative space times.

  • We therefore observe that the D-brane models of space-time foam do lead to a sort of violation of the equivalence principle [ref] , in the sense that the quantum-gravitational interactions of matter are not of universal strength among particle species.
