Description
We point out a pathology with a canonical approach to the semiclassical Einstein equation. To be precise, it is shown that such a theory, subjected to the Dirac constraint analysis, renders itself empty, that is, devoid of any nontrivial degrees of freedom. The reason is identified to be the diffeomorphism invariance.
