The variational method, backreactions, and the absorption probability in Wald type problems
Abstract We argue that the variational method in Wald type thought experiments, involves order of magnitude problems when one imposes the fact that $$\delta M$$ δ M is inherently a first order quantity itself. One observes that the contribution of the second order perturbations is actually of the fo...
