Well, an additional term involving an arbitrary scalar function times
the metric tensor can be added to the Einstein equations and and still

you mean a factor, not a term,
you times factors not terms,
you add terms

what is scalar function, one taking
a scalar as input or returning a
scalar as output?

how do you times a scalar
function on a tensor, please explain

a scalar times another scalar?
scalars has no direction, nor dimension

maintain their zero covariant divergence. The arbitrary scalar
function has no choice but to be constant for that to occur. These
conditions are not just arbitrarily assigned, they're derived.

do you mind a link with the derivations
