暗物质
Dark Matter
摘要:
引力对旋转速度的影响表明了单个星系中存在暗物质。牛顿力学通常用于推导旋转速度和重力之间的关系。在牛顿力学中,质量与引力有关。与此同时,在这样的星系中,似乎没有足够的引力质量来解释由旋转速度推导出的引力的大小。广义相对论包含了牛顿力学,也指出参考系提供了发展时空曲率的手段,时空曲率表达了引力场。我们可以合理地得出这样的结论:由于广义相对论具有更基本的特征,作为广义相对论关键要素的参考系构成了理解引力的基础,而不是质量。
英文摘要:
Gravitational force manifested in its affect on rotational velocity is what indicates the presence of dark matter in individual galaxies. Newtonian mechanics is generally used to derive the relationship between rotational velocity and gravitational force. In Newtonian mechanics, mass is associated with gravitation. At the same time, in such galaxies there appears to be insufficient gravitational mass to account for the size of the gravitational force deduced from rotational velocity. The general theory of relativity encompasses Newtonian mechanics and also indicates that reference frames provide the means to develop spacetime curvature that expresses the gravitational field. It is reasonable to conclude that because of the more fundamental character of the general theory of relativity, the reference frames that are a key element of the general theory form the basis for understanding gravitation, and not mass.
