# Constraints on relativity violations from gamma-ray bursts.

@article{Kosteleck2013ConstraintsOR, title={Constraints on relativity violations from gamma-ray bursts.}, author={V. Alan Kosteleck{\'y} and Matthew Mewes}, journal={Physical review letters}, year={2013}, volume={110 20}, pages={ 201601 } }

Tiny violations of the Lorentz symmetry of relativity and the associated discrete CPT symmetry could emerge in a consistent theory of quantum gravity such as string theory. Recent evidence for linear polarization in gamma-ray bursts improves existing sensitivities to Lorentz and CPT violation involving photons by factors ranging from ten to a million.
