Hypothetical Explanations for the Fermi Paradox

"A corollary of the Simulation Argument is that the universe’s computational capacity may be limited. Consequently, advanced alien civilizations may have incentives to avoid space colonization to avoid taking up too much “calculating space” and forcing a simulation shutdown.

A possible solution to the Fermi Paradox is that analogous considerations may drive them to avoid broadcasting their presence to the cosmos, and to attempt to destroy or permanently cripple emerging civilizations on sight.

This game-theoretical equilibrium could be interpreted as the “katechon” – that which withholds eschaton – doom, oblivion, the end of the world. The resulting state of mutually assured xenocide would result in a dark, seemingly empty universe intermittently populated by small, isolationist “hermit” civilizations."
