This is complex subject and I was reading that most of the science can be done by Newtonian but only precision effect calculation requires general relativity. Then there is dark matter also which contributes to gravitation. And the amount of dark matter in local area is also very small. Therefore, is it right to think that a suitable distribution of this dark matter along with the central mass can give same precision effect. GR = Newtonian on (central mass + dark matter). By considering some (may be weird) dark matter distribution around a mass, can the above lead to GR type accuracy.
