Are rogue machines lurking in the cosmos, quietly outlasting their creators? We explore the eerie possibility that ancient AI remnants, abandoned or self-replicating, could be hidden throughout the galaxy—watching, waiting, and perhaps even shaping the fate of civilizations.

Colonizing Rogue Planets

A trip deep into the far future, to the End of Earth
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
For most of human history, the end of Earth, the Universe, and Time itself were all identical, now we know the world will end in 4 billion years, long before the Universe begins to wind down. Today we will ask how we can extend that, and keep Earth around for far longer.

Dying Earth [Narration Only]

One of the biggest reasons for colonizing other worlds is to ensure we don't die with our own sun, but even those alien suns we might travel to will die one day. And yet, our image of stars living than erupting spectacular as a red giant or supernova, present a somewhat false impression, as those stellar remnants often last far longer than the stars which bore them. Could civilizations survive around these dead stars? Could they even outlast the End of the Universe, as the last stars fade away?

Dying Stars (Narration Only)

We continue our discussion of the Boltzmann Brain - a hypothetical randomly assembled mind rather than an evolved one - by looking at the Anthropic Principle and the Fine-Tuned Universe Theory, alternative ways of viewing the probability of our existence than the classic Copernican Principle.
