SFIA's Civilizations at the End of Time series, looking at how we might go about surviving the end of the world, the end of all stars, and even entropy itself.

Space Marines (Narration Only)

What if humanity’s future isn’t on Earth—or even other planets—but in colossal artificial worlds built in space? In this episode, we explore the O’Neill Cylinder, a visionary space habitat that could house millions, serve as interstellar arks, and transform the cosmos into a network of orbital civilizations. Join us as we dive into the design, potential, and profound societal implications of these Islands in the Sky.

How Many Alien Civilizations Are There?

This series takes a look at concepts for everything from Terraforming Planets and Interstellar Colonization to more down to Earth matters like Arcologies and Planet Wide Cities before examining using black holes as power sources for starships.We then leap into the far distance future at the end of time to examine civilizations surviving around black holes after all the stars have died out.

In the previous episode we saw how civilizations might not simply survive after all the stars in the Universe had died, but might indeed  thrive far better during the Black Hole Era of the Universe. Today, we will go beyond even the Dark Era to examine the concepts or Iron Star Civilizations, Boltzmann Brains, Reversible Computing, and even reversing Entropy itself.

Civilizations at the End of Time: Iron Stars

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)

An Introduction to SFIA's Civilizations at the End of Time series, looking at how we might go about surviving the end of the world, the end of all stars, and even entropy itself.

Civilizations At The End Of Time Series Introduction

According to modern cosmology, one day all the stars will burn out and the Universe will be full of dead planets, black holes, and other stellar remnants, slowing decaying till entropy brings the Heat Death of the Universe. But could this fate be postponed or even reversed?
