# On limitations of the extent of inertial frames in non-commutative relativistic spacetimes

@article{Smolin2010OnLO, title={On limitations of the extent of inertial frames in non-commutative relativistic spacetimes}, author={Lee Smolin}, journal={arXiv: General Relativity and Quantum Cosmology}, year={2010} }

We study the interplay of non-locality and lorentz invariance in a version of deformed or doubly special relativity (DSR) based on kappa-Minkowski spacetime. We find that Einstein’s procedure for an inertial observer to assign coordinates to distant events becomes ambiguous for sufficiently distant events. The accuracy to which two clocks can be synchronized turns out to depend on the distance between them. These are consequences of the non-commutativity of space and time coordinates or a…
