N-body Degravitation
A possible resolution to the cosmological constant problem may come from the graviton having a small mass or width. In this picture, the graviton carries extra polarizarions. Its helicity-0 or scalar mode is suppressed in regions of high density but becomes important on cosmological distance scales. We are solving the equations for this scalar component numerically as a part of an N-body simulation. This will allow us to quantify the impact of massive/resonance gravity on the formation of large scale structure for the first time.
