The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here we show that γ-ray bursts will be sensitive to an energy dispersion predicted by some approaches to quantum gravity. Many of the bursts have structure on relatively rapid timescales, which means that in principle it is possible to look for energy-dependent dispersion of the radiation, manifested in… 
Astrophysics (communication arising): A constraint on canonical quantum gravity?
Gamma rays from the γ-ray burst (GRB) 021206 have been reported to be strongly linearly polarized, with the estimated degree of polarization (80 ± 20%) being close to the absolute maximum of 100% —
Limits on quantum gravity effects from Swift short gamma-ray bursts
The delay in the arrival times between high and low energy photons from cosmic sources can be used to test the violation of the Lorentz invariance (LIV), predicted by some quantum gravity theories,
Delay of emission from extragalactic gamma-ray burst sources as a test for selecting a model of the universe
We obtained an order-of-magnitude estimate for the dispersion of light caused by the effect of quantum fluctuations on the propagation of electromagnetic waves in four-dimensional spacetime. We
Testing Lorentz Invariance with GRB 021206
Since the discovery of the cosmological origin of gamma-ray bursts (GRBs), there has been growing interest in using these transient events to probe the quantum gravity energy scale in the range
Prospects for constraining quantum gravity dispersion with near term observations
We discuss the prospects for bounding and perhaps even measuring quantum gravity effects on the dispersion of light using the highest-energy photons produced in gamma-ray bursts (GRBs) measured by
TESTING RELATIVITY AT HIGH ENERGIES USING SPACEBORNE DETECTORS
The Gamma-Ray Large Area Space Telescope (GLAST), to be launched in the fall of 2007, will measure the spectra of distant extragalactic sources of high energy γ-rays, particularly active galactic
A Search in Gamma-Ray Burst Data for Nonconstancy of the Velocity of Light
We discuss possible tests of the constancy of the velocity of light using distant astrophysical sources such as gamma-ray bursters (GRBs), active galactic nuclei (AGNs), and pulsars. This speculative

Detection of a γ-ray burst of very long duration and very high energy
ALTHOUGH γ-ray bursts (GRBs) have been known for more than 20 years, their origin remains mysterious1. Suggestions have ranged from nearby colliding comets2 to merging neutron stars at cosmological
Gamma-Ray Bursts Above 1 GeV
One of the principal results obtained by the Compton Gamma Ray Observatory relating to the study of gamma-ray bursts was the detection by the EGRET instrument of energetic ($>$100 MeV) photons from a
Gamma-ray bursters at cosmological distances
It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy
