Was Einstein Toying With Us?
First we invent the idea of a coordinate system. That's very helpful.
Then we frame all our physics in terms of it.
But we know that the laws of physics must be covariant - i.e. independent of our choice of coordinate system.
General Relativity showed that, and that alone would have been a very nice achievement.
But no, Einstein wove into it a description of gravity - placing gravity in a totally unique position.
No wonder we can't unify gravity with the rest of physics!!!!!!
