# Are the equations of relativity closed

## Main Question or Discussion Point

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?...

The cosmological constant is essentially just that.

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.
