rmond理论无需暗物质，同时也能完美预言出cmb的细节。也就是说，（r）mond理论的阿喀琉斯之踵已经不复存在。想让rmond理论被广泛接受，只差临门一脚。 不过，rmond理论和Λcdm模型一样，两者都还存在很多难以解释的问题。比如，这两者都难以完美预言星系团的

rmond理论在mond的基础上，引入了一个额外的场，使其成为相对论版本。这一改进使得rmond理论能够无需暗物质，同时完美预言宇宙微波背景辐射（cmb）的细节。这一点是mond理论之前的短板，因为cmb是现代天文学中最重要的发现之一，是大爆炸理论的关键证据。

RMOND is a scalar-tensor theory[23] with the scalar pro-viding for a conformal factor between two metrics. How-ever, since null geodesics are unaltered by conformal transfor-mations, such theories cannot produce enough lensing from baryons in the MOND regime. Sanders solved the lensing problem by changing the conformal into a disformal trans-

但是MOND假说也在不断发展，2020年，两位捷克理论物理学家Constantinos Skordis 和Tom Złośnik 在预印本网站上分享了他们对MOND理论的改进。他们在最大的宇宙尺度上添加了一个额外的场，相当于MOND理论的相对论版本（relativistic version of MOND），被称为RMOND理论。

RMOND is a subclass of the theories, mentioned above, of Skordis and Zlosnik, 2019, in which the speed of light and of tensor gravitational waves are always the same. Blanchet and Skordis, 2024 have propounded a relativistic theory starting from the Hořava gravity formulations discussed, e.g., in Sanders, 2011 and Blanchet & Marsat, 2011
