史瓦西坐标系和古尔斯特兰德-潘勒维坐标系中的引力
The force of gravity in Schwarzschild and Gullstrand-Painlevé coordinates
摘要:
我们推导出在史瓦西坐标系和古尔斯特兰德-潘勒维坐标系中试验质量的精确运动方程(牛顿形式,F=ma)。这些运动方程是简单的,比通常的测地线方程从克里斯托弗张量,仿射参数被删除。各种术语可以与重力测试进行比较。在力的形式中,引力可以解释为来自超光速粒子(引力子)的通量。我们证明了对牛顿引力的一阶相对论修正是由两个引力子相互作用引起的。
英文摘要:
We derive the exact equations of motion (in Newtonian, F=ma, form) for test masses in Schwarzschild and Gullstrand-Painlevé coordinates. These equations of motion are simpler than the usual geodesic equations obtained from Christoffel tensors in that the affine parameter is eliminated. The various terms can be compared against tests of gravity. In force form, gravity can be interpreted as resulting from a flux of superluminal particles (gravitons). We show that the first order relativistic correction to Newton's gravity results from a two graviton interaction.
