One idea about dark matter is that the laws of gravity are just different at large scale. This measurement rules out some of those theories ...

> the [measurement] enables us to test a certain class of modified gravity theories, which dispense with the dark matter paradigm and reproduce Modified Newtonian Dynamics (MOND) like behavior in the non-relativistic limit. Such modified theories of gravity have been dubbed “Dark Matter Emulators”. Some examples of these Dark Matter (DM) emulator theories include Bekenstein’s TeVeS theory and Moffat’s Scalar-Tensor-Vector gravity theory
