Part 7/11:

While the Berserker Hypothesis paints a grim picture of interstellar relations, it raises another key question: what if the aliens simply failed to notice us? With vast distances and timelessness between stars, it remains feasible that some intelligent life forms never had the opportunity to contact us before their civilizations ended or transformed.

The Hart-Tipler Conjecture

Building on the ideas of robotic exploration and colonization, the Hart-Tipler Conjecture argues that self-replicating machines or "Von Neumann Probes" should have abundantly populated our galaxy over time. Their absence implies that previous intelligent civilizations may not have existed, or if they did, they could have been eradicated by their own creations.
