Entropy Rising
Entropy Rising is a science fiction podcast and futurism podcast that explores the real science behind the future of humanity.
Hosted by Jacob Hyatt and Lucas, this sci-fi podcast breaks down topics like space exploration, Dyson swarms, interstellar travel, AI, and advanced civilizations using real engineering and physics.
If you’re looking for a science fiction podcast that goes beyond stories and asks what’s actually possible, this show connects speculative ideas to real-world science.
Each episode covers big questions like:
- Could we colonize Venus or Mars?
- What would a Dyson swarm actually look like?
- Are we alone in the universe?
- How would space warfare really work?
Whether you’re into speculative fiction, engineering podcasts, or space exploration podcasts, Entropy Rising gives you grounded, no-BS explanations of the future.
New episodes explore the intersection of science fiction, technology, and reality, built for listeners who want more than surface-level takes.

In this episode of Entropy Rising, Jacob and Lucas take a hard look at the Kardashev scale – a framework that ranks civilizations by the amount of energy they can harness – and ask whether it still serves as a meaningful tool today. After recapping Nikolai Kardashev’s original three-tier model and its purpose as a search tool for SETI, the hosts explore Carl Sagan’s numerical refinements, where Type I civilizations use ~10¹⁶ W, Type II tap ~10²⁶ W and Type III reach ~10³⁶ W. They question why humanity sits around Type 0.7 and debate whether the capability to modify our planet’s climate and harness agricultural energy counts toward Type I status.
The discussion then shifts to just how staggering the jump from Type I to Type II really is: a ten‑billion‑fold increase that would give each person on Earth the energy budget of an entire modern civilization. This segues into a critique of pop‑culture portrayals—why even Star Wars’ galactic empire doesn’t qualify as Type II—and an examination of how Kardashev’s framework overlooks differences between star types and the feasibility of empire‑scale coordination. The hosts introduce the Barrow scale and other proposals that categorize civilizations by their ability to manipulate matter (from genetic engineering to subatomic control), arguing that energy alone cannot describe technological sophistication. They also consider metrics based on computational capacity or semiconductor size, suggesting that once contact with extraterrestrial societies is possible, energy use may become less relevant.
This candid exploration interrogates assumptions, challenges popular misconceptions and highlights the need for multiple scales to capture the complexity of advanced civilizations.
