Could humanity one day mine entire planets, extract heavy metals from the Sun, and turn our solar system into a vast network of orbiting habitats? In this episode of Entropy Rising, Jacob and Lucas explore the science and engineering behind Dyson Spheres—massive structures designed to harness the full energy output of a star. While science fiction often depicts them as solid shells around a sun, we break down why that approach is likely impossible and discuss more realistic alternatives like Dyson Swarms and Dyson Bubbles.

A true Dyson Swarm would consist of millions of orbiting satellites, gradually built over time, each designed to capture and transmit solar energy. But where would the materials come from? The discussion takes a turn toward planetary disassembly, considering the idea of dismantling Mercury, mining asteroids, and even pulling resources directly from the Sun using magnetic field manipulation. With these advancements, a civilization could eventually create enough energy to power interstellar travel, artificial black hole batteries, and large-scale terraforming projects.

Building a Dyson Swarm presents massive engineering challenges, from maintaining stable orbits to dealing with extreme heat exposure near the Sun. We explore the physics behind these issues and examine potential solutions, including lightweight reflective materials, laser-based energy transmission, and advanced propulsion systems. The conversation also touches on the Kardashev Scale, which measures a civilization’s technological advancement based on energy consumption, and how Dyson technology could push humanity toward becoming a true Type II civilization.

Of course, the question remains—what would we actually do with this much energy? From powering interstellar spacecraft to creating artificial planets, the potential applications are nearly limitless. One of the most ambitious ideas discussed is the concept of a Kugelblitz Black Hole, a theoretical energy storage system that could serve as the most efficient power source ever conceived. Could a future civilization use these methods to reshape not just our solar system, but others as well?

To close the episode, we introduce a new initiative: featuring independent science fiction authors at the end of each episode. These authors will share a short description of their work in their own words, giving listeners an opportunity to discover new and thought-provoking stories. If you're fascinated by the future of spacefaring civilizations, deep-space engineering, and the ultimate fate of human expansion, this is an episode you won’t want to miss.
