China’s FAST Telescope Could Detect Self-Replicating Alien Probes
One of the most challenging questions to answer when confronting the Fermi Paradox is why exponentially scaling technologies haven’t taken over the universe by now. Commonly known as von Neumann probes, the idea of a self-replicating swarm of extraterrestrial robots has been a staple of science fiction for decades. But so far, there has never …

Beyond “Fermi’s Paradox” XVII: What is the “SETI-Paradox” Hypothesis?
Another reason we haven’t heard from aliens is that the possibility that every everyone is listening, but nobody’s messaging!
If Aliens Are Out There, We’ll Meet Them in a Few Hundred Million Years
