Re: [請益] 相對論
回Lindemann對廣相還是狹相的看法:
雖然之前很多問題上,我看到你的回應和我的觀點是相同的,
但在這個問題上,我要提出,condensed是對的。(僅有下面這一句相同,其他不予置評)
在狹相的範疇確實可以就可以處理加速度和加速座標系。
廣相的引入只是把重力考慮進來而已,並非一定要廣相才能討論加速度。

而廣相引入重力的方式,是把有重力的情況類比到加速座標系,
也就是所謂的等效原理。
舉例來說:光在重力場中會彎曲,先簡化問題成均勻重力場(重力加速度g),
則等效原理說這個和在一個加速(a=g)的座標看到的光的路徑是相同的。
而加速座標中看到的光的路徑,可以由狹相討論出來。
