Einestein's equations are obtained from varying the
Hilbert action with respect to the full degrees of freedom of the
metric, i.e. the metric variation is not restricted to preserving
constant signature.

What's a "signature" ?

It's pretty fucking funny that you don't know what the signature of a
metric is even though you have spent years making crank arguments
about general relativity.

The signature of a metric is the number of its' positive & negative
eigenvalues.

I can't help this guy, but at least I know it.
