MOG is a fully relativistic modified theory of gravity based on an action principle. The MOG field equations are exactly solvable numerically in two important cases. In the spherically symmetric, static case of a gravitating mass, the equations also admit an approximate solution that closely resembles the Reissner-Nordstrom metric. Furthermore, for weak gravitational fields, a Yukawa-type modification to the Newtonian acceleration law can be obtained, which can be used to model a range of astronomical observations. Without nonbaryonic dark matter, MOG provides good agreement with the data for galaxy rotation curves, galaxy cluster masses, and gravitational lensing, while predicting no appreciable deviation from Einstein's predictions on the scale of the solar system. Another solution of the field equations is obtained for the case of a a spatially homogeneous, isotropic cosmology. MOG predicts an accelerating universe without introducing Einstein's cosmological constant; it also predicts a CMB acoustic power spectrum and a mass power spectrum that are consistent with observations without relying on non-baryonic dark matter. Increased sensitivity in future observations or space-based experiments may be sufficient to distinguish MOG from other theories, notably the LCDM "standard model" of cosmology.

Crossover in extended Newtonian gravity emerging from thermodynamics
在最近的一篇论文中（Ván，P.; Abe，S. Physica A 2022，588，126505），已经发现，耦合到流体并被允许作为与热力学第二定律一致的热力学变量的标量场仅仅是引力场，因此已经预测了扩展牛顿引力的出现。由此产生的势场方程是非线性的，并且允许对数势作为奇异解，这表明它与暗物质难题有关。在这里，非线性场方程的一般分析进行。我们发现，涌现力场在流体外部表现出1/r和1/r^2力之间的非尖锐交叉，这取决于本理论的空间尺度特征，该特征将在暗物质难题的背景下进行观测检验。然后，作用泛函的潜在的出射场和场能量被证明是免费的红外发散。并对本理论与修正的牛顿动力学的区别作了评述。
