Description
We show how a system of $N>>1$ horizonless conic singularities, with average opening angle at the horizon $\langle \Theta \rangle=2\pi$, can effectively approximate the geometry and the entropy of a semiclassical black hole. We test what happen to in-going informations in such a system, with a simple gedanken experiment: we consider a plane wave function in-going in this system of N conic singularities. The initial quantum wave will subsequently scatter on $N$ conic singularities, and the resultant dynamics will be a quantum chaotic one. This system is nothing but a quantum Sinai billiard. As a consequence, information is "practically" lost in this system. Our approach also seems motivated by fuzzballs' physics, where BPS microstates and conical defects are typically considered.
