Jacob Bekenstein developed tensor-vector-scalar gravity, a relativistic theory intended to realize modified Newtonian dynamics. The construction supplements the metric tensor with dynamical scalar fields and vector fields.
A nonrelativistic rule for stellar motion alone does not determine how light bends. His 2004 theory addressed both slow-particle dynamics and gravitational lensing, while examining the high-acceleration limit and Solar-System tests. This made the proposal a broader physical framework with multiple observational consequences, rather than merely a fit to a galaxy rotation curve.[ref]
Relativistic gravitation theory for the MOND paradigm by Jacob Bekenstein. Abstract: dynamical fields, Newtonian and MOND limits, post-Newtonian tests and lensing

Jacob Bekenstein was a prominent theoretical physicist known for his groundbreaking work in the field of black hole thermodynamics and quantum gravity. Born on March 1, 1947, in Jerusalem and passing away on August 16, 2023, Bekenstein is best known for proposing that black holes have entropy and that this entropy is proportional to the area of their event horizon, a concept he introduced in the early 1970s.
