用平坦时空中的Heaviside-Maxwell(矢量)引力解释重力探测器B的实验结果
Explanation of Gravity Probe B Experimental Results using Heaviside-Maxwellian (Vector) Gravity in Flat Space-time
摘要:
美国航天局的重力探测器B(GP-B)实验旨在检验爱因斯坦1916年关于弯曲时空中引力的相对论张量理论(广义相对论)的理论预测,该理论预测涉及在缓慢旋转的大质量物体(如地球)场中运动的陀螺仪的自旋轴进动。在2011年,GP-B任务报告了其测量数据的旋进(位移)角的四个球形陀螺仪的自旋轴安装在一个卫星轨道642公里(400英里)以上的地球在极地轨道。报告的结果是一致的GR的预测。第一次,在这里,我们报告的GP-B实验结果的本科水平的解释,使用Heaviside麦克斯韦(矢量)重力(HMG)在平坦的时空,首先由Heaviside在1893年制定,后来考虑/重新发现了许多作者。我们对GP-B结果的新解释为HMG提供了一种新的检验方法,其简单性和新的视角值得该领域研究者的关注。
英文摘要:
The Gravity Probe B (GP-B) Experiment of NASA was aimed to test the theoretical predictions of Einstein's 1916 relativistic tensor theory of gravity in curved space-time (General Relativity (GR)) concerning the spin axis precession of a gyroscope moving in the field of a slowly rotating massive body, like the Earth. In 2011, GP-B mission reported its measured data on the precession (displacement) angles of the spin axes of the four spherical gyroscopes housed in a satellite orbiting 642 km (400 mi) above the Earth in polar orbit. The reported results are in agreement with the predictions of GR. For the first time, here we report an undergraduate level explanation of the GP-B experimental results using Heaviside-Maxwellian (vector) Gravity (HMG) in flat space-time, first formulated by Heaviside in 1893, and later considered/re-discovered by many authors. Our new explanation of the GP-B results provides a new test of HMG apart from the existing ones, which deserves the attention of researchers in the field for its simplicity and new perspective.
