As confused as this article seems, it does at least reference one Actual Paper: http://arxiv.org/PS_cache/arxiv/pdf/1101/1101.0931v2.pdf I haven't had a chance to look through it yet, but here's the abstract: We propose a deepening of the relativity principle according to which the invariant arena for non-quantum
physics is a phase space rather than spacetime. Descriptions of particles propagating and interacting in spacetimes are constructed by observers, but different observers, separated from each other by translations, construct
different spacetime projections from the invariant phase space. Nonetheless, all observers agree that interactions
are local in the spacetime coordinates constructed by observers local to them. This framework, in which absolute locality is replaced by relative locality, results from deforming momentum
space, just as the passage from absolute to relative simultaneity results from deforming the linear addition of
velocities. Different aspects of momentum space geometry, such as its curvature, torsion and non-metricity, are
reflected in different kinds of deformations of the energy-momentum conservation laws. These are in principle
all measurable by appropriate experiments. We also discuss a natural set of physical hypotheses which singles
out the cases of momentum space with a metric compatible connection and constant curvature. |
