Abstract: We propose a generic test for models in which gravity is modified to do awaywith dark matter. These models tend to have gravitons couple to a differentmetric than ordinary matter. A strong test of such models comes from comparingthe arrival time of the gravitational wave pulse from a cosmological event suchas a supernova with the arrival times of the associated pulses of neutrinos andphotons. For SN 1987a we show that the gravity wave would have arrived 5.3 daysafter the neutrino pulse.
