going on? One has to keep these results in perspective, since it is easy to get carried away and believe that perturbation theory should work way beyond where it was meant to do so. In the calculation of the present paper we find that the radiated energy goes as $P^4$. This is good, since our perturbative parameter is $P$ and therefore this means that the corrections are small. In the case of colliding black holes the radiated energies contain terms that go as (see reference [@GlNiPrPuboost2]) $L^4$, $P^2 L^2$ and $P L^3$, where $L$ is the separation of the black hole centers in the conformally related flat space. If one simply increases the value of $P$ keeping $L$ constant, it is obvious that the contribution we consider in this paper will quickly dominate. However, one is clearly pushing things beyond the realm in which these calculations were meant to be reliable. One is essentially forcing [*a higher order term in perturbation theory*]{} to a regime in which it is larger than the lower order terms!

Therefore the conclusion of this paper has to be read in the following way: the terms coming from the “relaxation” of a conformally flat hole
