[1111.6131] The Fermi Paradox, Self-Replicating Probes, and the Interstellar Transportation Bandwidth
"We also consider several other models that seek to explain the Fermi Paradox, most notably percolation theory and two societal-collapse theories. In the former case, we find that it imposes unnatural assumptions which likely render it unrealistic. In the latter case, we present a new theory of interstellar transportation bandwidth which calls into question the validity of societal-collapse theories."
