你这攻下狭义没攻下广义相对论的物理装不懂大拿居然没有闹清楚什么是“classical relativity”,你以为相对论开始于爱因斯坦,从狭义到广义?
老芦讨论的是"哥白尼体系与托勒密体系"谁为参照中心的问题,与老爱的相对论完全无关。

地球确实是月亮公转的中心,而太阳确实是太阳系的中心,但两者都不是宇宙的中心。
不仅如此,如果用运动的相对性来说,确实可以把地球视为参考系,而宇宙就是围绕它旋转。从物理学的基本原理来说,老托其实一点都不错。 |
也不知道你有神马威力无穷的杜鲁门引力,将其引入爱因斯坦的相对论?
还居然懂装不懂的解释道:

classical relativity 这种说法不是物理上的常用的正规的说法,正规的说法是special relativity |
让老稀这外行羞愧。只能去yahoo求救:
What are the differences between special relativity and classical relativity?
Best Answer:
Classical relativity is pre-Einstein. It talks about what happens when you have relative motion of objects in classical Newtonian mechanics. For example, if two cars are both going 50 mph, and they are going in the same direction, they are moving 0 mph relative to each other. And if they are driving in opposite directions they are going 100 mph relative to each other.
Special relativity is the theory that first made Einstein famous and gave us E=MC2 (which expresses the equivalency of matter and energy). It also set light as the universal speed limit and theorizes that light always moves the same speed relative to everything else, which means that time must be flexible and inextricably linked to space.
General relativity was also created by Einstein, and it adds the concept of gravity to special relativity. It depicts gravity as a sort of geometrical construct of spacetime, and describes mass as capable of distorting spacetime.
简单的说:classical relativity是指爱因斯坦前的伽利略发现的“运动的相对性”。
