I'm reading wald page 85, and he defines a stress-energy tensor for the linearized gravitational field. he mentions that it not gauge invariant as a problem. but isn't that a general property of any tensor (except scalars). so any stress-energy tensor will not be gauge invariant (change of coordinates).(adsbygoogle = window.adsbygoogle || []).push({});

is it because we're using η and not the full metric?
