Cyclic Apocalypses

A look at the possibility of future civilizations rising and falling.

It's long been observed that empires tend to rise and fall in a seeming cycle, never identical but sharing many similarities. Today we will examine the idea that this may be the reason that we have encountered no advanced civilizations in our own galaxy, and that the solution the Fermi Paradox, as to why we have seen no alien civilizations, may be that they are caught in a perpetual loop. Unable or unwilling to use technology which might allow them to travel the cosmos. We will also consider if such a loop may await us, or that we are already in it.
