廣義相對論(一) 最幸運的想法

當時我正坐在伯恩專利局的椅子上,突然靈光一現,想到如果有人掉落下來,將不會感覺到自己的重量。
wiki 表示:
General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime.

In particular, the curvature of spacetime is directly related to the four-momentum (mass-energy and linear momentum) of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations.

接下來的重要工作,就是推導 Einstein field equations,然後根據方程式,去解釋 gravitational time dilation and frequency shift,light deflection and gravitational time delay,gravitational waves,orbital effects and the relativity of direction 等等物理現象。

不知道我有沒有能力可以理解這一切,希望是可以。
