标题： Modified Gravity (MOG), the speed of gravitational radiation and the event GW170817/GRB170817A

摘要： 修正引力（MOG）是一种协变的、相对论性的替代引力理论，其场方程来源于一个补充了时空度规张量的矢量场和标量场的作用量。 该理论中的引力（自旋 2）波和电磁波都沿其单一度规的零测地线传播。 尽管最近有人声称与此相反，MOG 满足弱等效原理，并且与中子星合并及GW170817/GRB170817A伽马射线暴事件的观测结果一致。 显示英文摘要

摘要： Modified gravity (MOG) is a covariant, relativistic, alternative gravitational theory whose field equations are derived from an action that supplements the spacetime metric tensor with vector and scalar fields. Both gravitational (spin 2) and electromagnetic waves travel on null geodesics of the theory's one metric. Despite a recent claim to the contrary, MOG satisfies the weak equivalence principle and is consistent with observations of the neutron star merger and gamma ray burster event GW170817/GRB170817A.
