Abstract

Abstract In any physical system, when we move from short to large scales, new spacetime symmetries emerge which help us to simplify the dynamics of the system. In this letter we demonstrate that certain variations on the symmetries of general relativity at large scales generate the effects equivalent to dark matter ones. In particular, we reproduce the Tully-Fisher law, consistent with the predictions proposed by MOND. Additionally, we demonstrate that the dark matter effects derived in this way are consistent with the predictions suggested by MOND, without modifying gravity.

塔利-费雪定律和暗物质效应是通过修正对称性推导出来的

在任何物理系统中，当我们从短尺度移动到大尺度时，新的时空对称性就会出现，这有助于我们简化系统的动力学。在这封信中，我们证明了广义相对论的对称性在大尺度上的某些变化会产生相当于暗物质的效应。特别是，我们重现了Tully-Fisher定律，与MOND提出的预测一致。此外，我们证明了以这种方式导出的暗物质效应与MOND提出的预测一致，而不改变重力。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
