Project Unruh is named after the Unruh effect which was first described by W.G.Unruh in 1976, predicting that an accelerating observer will observe black-body radiation where an inertial observer would observe none. The Unruh effect may imply a form of Unruh radiation.
It has been suggested by McCulloch (see publications below) that Unruh radiation may 1) cause inertia and 2) be subject to a Hubble-scale Casimir effect. This model is called quantised inertia and predicts several anomalous observations including the galaxy rotation problem and cosmic acceleration.
The aim of this project is to test quantised inertia experimentally, and to determine whether we can affect inertia by interfering with Unruh radiation and devise ways to test its prediction of faster than light travel.
Several technical papers have already been published in this area including:
