This proposal was rescinded by me for 2 reasons. First the terms in the Lagrangian for gravity would change under a rotation of the coordinates. Gravity conserves angular momentum - first observed by one of Kepler's laws - so the proposal is not consistent with a basic property of gravity. Second, it does not allow for gauge symmetry, the cancellation does not happen. Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show touches three important puzzles: how to unify gravity and light, how to quantize such a proposal, and a new way to explain how galaxies rotate.
