What if we could mine the Sun? What if we didn’t just build around stars, but engineered them? In this episode of Entropy Rising, we explore two of the most mind-bending concepts in astrophysics: star lifting and stellar engines, technologies a Kardashev Type II civilization might use to reshape entire solar systems.

We break down how star lifting works, from using magnetic fields to extract solar plasma, to sorting elements like iron and carbon for megastructure construction. You’ll learn why advanced civilizations might want to do this. not just to build Dyson swarms or fusion reactors, but to extend a star’s life or reclassify it altogether. We also explore how this process might be used to terraform planets,or even refuel stars.

Then, we take it one step further. What if you could move a star? We discuss the science behind stellar engines, including the Shkadov thruster, the Caplan engine, and the far more efficient Star Tug. These are not sci-fi magic—they’re grounded in real physics. By redirecting radiation or harvesting and ejecting stellar mass, these hypothetical devices could shift entire stars across the galaxy… slowly, but surely.

And yes, we talk about the crazy implications. Turning the entire solar system into a generation ship. Moving stars to avoid supernovae. Using lasers and plasma jets to reshape the cosmos.

Whether you're here for the theoretical physics, the sci-fi applications, or just to melt your brain a little, this episode delivers. It’s the kind of future tech that’s so extreme, it sounds like fantasy... but might actually be inevitable.

If you’ve ever wondered what a truly advanced civilization does with its power, this is the episode you’ve been waiting for.
