论文摘要
暗物质问题是现代物理学中最紧迫的问题之一。由于没有直接检测实验的主张,该实验支持了虚幻的暗物质的存在,而这些暗物质的存在是为了解释星系的平坦旋转曲线,而且由于重力替代理论的整个问题仍然有争议,因此可能值得重新考虑一般相对论(GR)本身以获取可能出路的熟悉的基础。 最近,人们发现,偏斜的阵列三个张量球场 - 兰开斯张量场 - 产生Weyl张量的差异化,提供了牛顿重力力量的适当相对论类似物。通过考虑其保形的不变性,兰开斯张量会导致一项修改的加速度定律,可以在GR本身的框架内解释星系的平坦旋转曲线,而无需任何暗物质。
The dark matter problem is one of the most pressing problems in modern physics. As there is no well-established claim from a direct detection experiment supporting the existence of the illusive dark matter that has been postulated to explain the flat rotation curves of galaxies, and since the whole issue of an alternative theory of gravity remains controversial, it may be worth to reconsider the familiar ground of general relativity (GR) itself for a possible way out. It has recently been discovered that a skew-symmetric rank-three tensor field - the Lanczos tensor field - that generates the Weyl tensor differentially, provides a proper relativistic analogue of the Newtonian gravitational force. By taking account of its conformal invariance, the Lanczos tensor leads to a modified acceleration law which can explain, within the framework of GR itself, the flat rotation curves of galaxies without the need for any dark matter whatsoever.
