标题： Inconsistencies in Verlinde's emergent gravity

摘要： 我们指出，Verlinde 最近提出的新兴引力理论存在一些内部不一致性。 该提案的主要思想是在短距离处保留经过大量实验验证的广义相对论，但在观测到谜团的大尺度上（特别是暗物质问题）通过使用某些熵的概念对其进行修改。 我们首先指出，作为保守力的引力很难（甚至可能无法）被描述为一种熵力。 然后我们证明，利用弹性应变概念推导出的MOND关系并不自洽。 当正确处理时，Verlinde 的复杂程序恢复了标准牛顿引力，而不是MOND。 显示英文摘要

摘要： We point out that recent Verlinde's proposal of emergent gravity suffers from some internal inconsistencies. The main idea in this proposal is to preserve general relativity at short scales where numerous tests verified its validity, but modify it on large scales where we meet puzzles raised by observations (in particular dark matter), by using some entropic concepts. We first point out that gravity as a conservative force is very difficult (if possible at all) to portray as an entropic force. We then show that the derivation of the MOND relation using the elastic strain idea is not self-consistent. When properly done, Verlinde's elaborate procedure recovers the standard Newtonian gravity instead of MOND.
