Abstract

One of the experimental tests of Lorentz invariance violation is to measure the helicity dependence of the propagation velocity of photons originating in distant cosmological obejcts. Using a recent determination of the distance of the Gamma-Ray Burst GRB 041219A, for which a high degree of polarization is observed in the prompt emission, we are able to improve by 4 orders of magnitude the existing constraint on Lorentz invariance violation, arising from the phenomenon of vacuum birefringence.

    • Permutation City[1] by Greg Egan is one particular (hard SF) look at this idea. I'm pretty sure there are others, it's quite a common trope. In the (hopefully) real world, there was something fairly recently about possible violations of the Planck length…
