重力和MOND的替代方法

Alternative approach to gravity and MOND

Jozef Klačka

摘要:

为了使经典引力二体问题也适用于弱引力场,本文对经典引力二体问题进行了推广。运动方程对地球和大宇宙尺度都成立,牛顿引力定律代表了广义形式的数学极限。动机来自于星系自转曲线的观测结果。没有假设存在暗物质。物理学的关键定律成立,并且系统的势能相对于两个物体的质量是对称的。几十年来发表的结果的缺点,包括MOND理论和错误但熟悉的方法,被克服。强调了对寻找基本物理理论的影响。过去几个世纪的一些传统思想不适用于小加速度区,例如,使用势和场的拉格朗日密度的最小作用量原理不起作用。我们可以期待我们对宇宙演化的理解发生巨大变化。

英文摘要:

The classical gravitational two-body problem is generalized in order to be applicable also to weak gravitational fields. The equation of motion holds both for terrestrial and large cosmic scales, the Newtonian gravitational law represents a mathematical limit of the generalized form. Motivation comes from observational results on rotation curves of galaxies. Existence of a dark matter is not assumed. The crucial laws of physics hold and also the potential energy of the system is symmetric with respect to masses of the two bodies. Shortcomings of the results published for decades, including MOND theories and false-yet-familiar approaches, are overcome. The impact on searching for a fundamental physical theory is stressed. Some of the conventional ideas of the past centuries do not hold for the zone of small accelerations, e.g., the principle of least action using the Lagrangian density of potentials and fields does not work. We may look forward to great changes in our understanding of the evolution of the Universe.
