爱因斯坦引力场
Einstein's gravitational field
摘要:
关于爱因斯坦广义相对论中的引力场的性质,存在着一些混淆,如文献中所证明的。有人认为,这种混乱是由于在解释的引力场的变化。爱因斯坦将引力的存在与加速物体的惯性运动(即自由落体中的物体)联系起来,而当代物理学家则将引力的存在与时空曲率(即潮汐力)联系起来。把引力解释为时空中的曲率是爱因斯坦不同意的一种解释。
英文摘要:
There exists some confusion, as evidenced in the literature, regarding the nature of the gravitational field in Einstein's General Theory of Relativity. It is argued here the this confusion is a result of a change in interpretation of the gravitational field. Einstein identified the existence of gravity with the inertial motion of accelerating bodies (i.e. bodies in free-fall) whereas contemporary physicists identify the existence of gravity with space-time curvature (i.e. tidal forces). The interpretation of gravity as a curvature in space-time is an interpretation Einstein did not agree with.
