This theory builds on Sanders’s stratified theory by positing a disformal relation between the physical and Einstein metrics in terms of a dynamical field denoted U. For 10 points each:
[10h] Name this relativistic extension of Modified Newtonian Dynamics proposed by Jacob Bekenstein. This theory replicates the behavior of Milgrom’s interpolation function in the weak-field limit using its three namesake quantities.
ANSWER: Tensor-Vector-Scalar gravity [or TeVeS]
[10m] Bekenstein introduced TeVeS to fix problems with the relativistic version of a theory in which this quantity is aquadratic (“A-quadratic”) in grad phi. Derivatives of this quantity with respect to generalized coordinates appear on either side of a set of equations partially named for Euler.
ANSWER: Lagrangian [accept Euler–Lagrange] (The previous theory is AQUAL.)
[10e] Both TeVeS and AQUAL fix the failure of this result for classical MOND. This result, which follows from translation symmetry of the Lagrangian by Noether’s theorem, says that the product of mass and velocity remains constant in a system. A description is acceptable.
ANSWER: conservation of linear momentum [accept equivalents]
