We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a paradigm that explains the observed universal galactic acceleration scale and related phenomenology. We discuss phenomenological requirements leading to its construction and demonstrate its agreement with the observed cosmic microwave background and matter power spectra on linear cosmological scales. We show that its action expanded to second order is free of ghost instabilities and discuss its possible embedding in a more fundamental theory.
我们提出了一种相对论性引力理论，该理论导致了修正牛顿动力学，这是一种能够解释观测到的宇宙星系普遍加速尺度及相关现象学的范式。我们讨论了导致其构建的现象学要求，并证明了它在宇宙学线性尺度上与观测到的宇宙微波背景和物质功率谱的一致性。我们表明，其展开至二阶的作用不存在鬼不稳定，并讨论了它在更基础理论中的可能嵌入方式。
