Are the equations of relativity "closed" Are the equations of relativity "closed" i mean if we can add an extra term of 0 covariant derivative to them without alter thes olution i mean if we have the equations Gab=Tab , will the equations Gab+Uab=Tab with DUab=0 (covariant derivative) can both equation provide the same geometrical interpretation of gravity?...
Re: Relativity Can you rephrase this question? You write ".., will the equations (..) can both provide the same geometrical interpretation of gravity." I don't know what this means. They clearly have different solutions. Pmb
