Tensor-Vector-Scalar gravity (TeVeS) is a proposed relativistic theory which purports to explain galactic rotation curves without invoking dark matter. Originated by Jacob Bekenstein in 2004, it incorporates various dynamical and non-dynamical tensor fields, vector fields and scalar fields. The theory reduces to Modified Newtonian Dynamics (MOND) for large distance scales at which MOND predictions differ from Newtonian Mechanics, but (unlike MOND) it is claimed to be consistent with tests of General relativity.^[1] TeVeS also helps explain phenomena that MOND could not, such as gravitational lensing. Although it is widely claimed that recent observations of the Bullet Cluster prove that galactic rotation curves are explained by dark matter rather than alternative theories of gravity such as TeVeS,^[2][3] MOND proponents argue that TeVeS can also account for these observations.^[4]
