# Twistor relative locality

@article{Smolin2013TwistorRL, title={Twistor relative locality}, author={Lee Smolin}, journal={arXiv: High Energy Physics - Theory}, year={2013} }

We present a version of relative locality based on the geometry of twistor space. This can also be thought of as a new kind of deformation of twistor theory based on the construction of a bundle of twistor spaces over momentum space. Locality in space-time is emergent and is deformed in a precise way when a connection on that bundle is non-flat. This gives a precise and controlled meaning to Penrose’s hypothesis that quantum gravity effects will deformtwistorspace in such a way as to maintain…

This work introduces a new kind of deterministic dynamics for a causal set in which new events are generated from pairs of progenitor events by a rule which is based on extremizing the distinctions between causal past sets of events.
