由于广义协方差正则公式的微妙特征，一类新的修正引力理论自然允许在有效时空解中出现类似MOND的行为（修正牛顿动力学），而无需引入新的场。详细的分析揭示了与各种量子引力特征的关系，特别是在正则方法中，并显示了潜在的观测相关性的几个属性。因此，MOND的基本起源和暗物质问题的相应解决方案是可能的和可检验的。
A new class of modified gravity theories, made possible by subtle features of the canonical formulation of general covariance, naturally allows MOND-like behavior (MOdified Newtonian Dynamics) in effective space-time solutions without introducing new fields. A detailed analysis reveals a relationship with various quantum-gravity features, in particular in canonical approaches, and shows several properties of potential observational relevance. A fundamental origin of MOND and a corresponding solution to the dark-matter problem are therefore possible and testable.
