Entropy Rising

What happens to civilization when people can live for hundreds or even thousands of years?

Life extension could transform humanity, but it also raises some difficult questions. If people no longer die of old age, what happens to wealth, political power, and opportunities for future generations? Could we end up in a gerontocracy, where the same individuals and families control society for centuries?

In this episode of Entropy Rising, we explore how radical life extension could reshape civilization, from immortal political leaders and powerful family dynasties to the possibility of economic stagnation. We also discuss potential solutions, including term limits, wealth redistribution, and whether interstellar colonization could provide an escape from societies where opportunity has disappeared.

Drawing on ideas from science fiction, including Peter F. Hamilton's Commonwealth Saga, The Culture series, and Silo, we examine how humanity might adapt to a world where living for 500 years is normal.

Would immortality create a more prosperous civilization, or would it leave future generations trapped under the same people forever?

What if we could build structures that reach into space without relying on the strength of steel or concrete? From Lofstrom loops capable of launching spacecraft into orbit to towers stretching 100 kilometers into the sky, actively supported structures could fundamentally change what's possible in engineering.

In this episode of Entropy Rising, Jacob and Lucas explore the physics of active support, an engineering concept that uses continuously moving mass and momentum to support structures that would otherwise collapse under their own weight.

We start with the Lofstrom loop, a proposed 2,000-kilometer-long launch system suspended approximately 80 kilometers above Earth. By accelerating a continuous loop of material to incredible speeds, this structure could potentially launch people and cargo toward orbit while dramatically reducing the need for rocket propulsion.

We also explore Atlas pillars, skyscrapers that could theoretically extend into space, and actively supported bridges capable of spanning enormous distances without conventional supports.

How would these structures actually work? Could we build them using today's technology? And what happens if the systems keeping them standing suddenly lose power?

Join us as we explore the fascinating physics, engineering challenges, and potential applications of actively supported megastructures.

What will technology look like in 100 years? By 2126, advances in artificial intelligence, biotechnology, energy storage, and space exploration could fundamentally transform how we live.

In this episode of Entropy Rising, Jacob and Lucas explore what the next century of technological progress might bring. From revolutionary battery technologies and electric aircraft to personalized medicine, nanotechnology, and the possibility of dramatically extending human lifespans, we examine how today's scientific breakthroughs could shape tomorrow's world.

We also discuss the future of climate change, the development of industries in space, and why humanity's next 100 years may lay the groundwork for even greater achievements in the centuries beyond.

Rather than making wild predictions, we're extrapolating from technologies already being developed to explore what might realistically be possible by 2126.

What do you think will be the biggest technological breakthrough of the next 100 years? Let us know in the comments!

How do stars work, what powers nuclear fusion, and why do some stars survive for trillions of years while others burn out in just a few million? In this episode of Entropy Rising, we take a deep dive into the physics of stars, exploring their inner workings, life cycles, and the incredible possibilities of stellar engineering.

We begin with nuclear fusion, breaking down the proton-proton chain, the Coulomb barrier, and the surprising role of the weak nuclear force in keeping our Sun shining. We also explore how different fusion processes, stellar mass, and convection determine how efficiently stars burn their fuel.

From red dwarfs and blue supergiants to white dwarfs, neutron stars, and black holes, we examine how stars evolve and what happens when gravity finally overcomes the forces holding them together.

But understanding stars is only the beginning. Could an advanced civilization manipulate them? We explore stellar engines capable of moving entire solar systems, star lifting to extract valuable materials, and techniques that could extend a star's lifespan by billions of years.

Join Jacob and Lucas as we explore how stars work and how humanity might one day transform them into the ultimate tools for interstellar civilization.

Dyson spheres are among the most iconic megastructures in science fiction, but they're also among the most misunderstood.

What if building a Dyson sphere wasn't a massive engineering project spanning thousands of years, but instead the natural outcome of a civilization expanding into space?

In this episode of Entropy Rising, Jacob and Lucas explore the science behind Dyson spheres and Dyson swarms, why the traditional solid-shell design doesn't make much sense, and how billions of O'Neill cylinders and space habitats could gradually surround a star without anyone ever planning to build a megastructure.

We also discuss the Kardashev scale, Type II civilizations, nuclear fusion, the Fermi paradox, and how astronomers might detect alien megastructures by looking for infrared waste heat.

Are Dyson swarms an inevitable outcome of advanced civilizations, or could future technologies make them unnecessary?

What if planets are actually one of the least efficient places for an advanced civilization to live?

In this episode of Entropy Rising, we explore why humanity may eventually move away from planets and build massive space habitats instead. We compare terraforming Mars or Venus with constructing O’Neill cylinders and other artificial habitats, and look at how a mature space economy could use asteroids, Mercury, and other planetary resources to create vastly more living space than planets provide.

We also dig into what life inside these habitats could actually look like: customized environments, farms, cities, nature preserves, and entire communities designed from the ground up. Rather than cramped space stations, future habitats could hold anywhere from thousands to millions of people and eventually scale into much larger structures like McKendree cylinders, Bishop rings, and Topopolises.

The biggest advantage may be scale. A planet uses most of its mass simply to produce gravity, while that same material could potentially be converted into an enormous number of rotating habitats and far more usable living area. That raises a strange possibility: instead of terraforming planets, future civilizations may harvest them for raw materials and build millions of artificial worlds in space. 

And once civilization already lives in self-sufficient habitats, interstellar expansion starts to look very different. A habitat can remain a home whether it is orbiting the Sun or spending centuries traveling to another star, making generation ships and distributed interstellar civilizations far more practical.

Would you rather live on a planet or inside a massive space habitat?

Wormholes are one of the most fascinating ideas in theoretical physics, but how much of what we see in science fiction is actually possible?

Support us on Pateron :https://www.patreon.com/c/EntropyRising

In this episode of Entropy Rising, we take a deep dive into wormholes, from Einstein-Rosen bridges and general relativity to the biggest problems with keeping a wormhole open. We explore what physicists actually say about traversable wormholes, exotic matter, stability, and whether these shortcuts through spacetime could ever exist in the real universe.

Then we push beyond the known physics and ask the fun question: if stable wormholes did exist, what could we actually do with them? Interstellar travel, instant transportation, communication across enormous distances, and some of the stranger consequences that science fiction loves to explore.

From real physics to hard science fiction, this is a full discussion of what wormholes are, why they are so difficult, and what they could mean for the future of space travel.

AI is making mass surveillance cheaper, faster, and far more powerful, but how far could it actually go?

In this episode of Entropy Rising, we explore the future of surveillance technology and what it could mean for privacy. We discuss AI-powered cameras, facial recognition, surveillance capitalism, targeted advertising, predictive policing, AI judges, smart cars, and the growing amount of personal data collected by governments and corporations.

We also look further into the future. What happens when surveillance moves beyond smartphones and cameras and into neural implants, augmented reality, and other technology embedded directly into our bodies? Could avoiding surveillance eventually mean disconnecting from society entirely?

There are real benefits to some of these technologies, from solving crimes to finding missing people and improving emergency response. But as AI becomes better at processing enormous amounts of data, the question becomes less about whether surveillance is possible and more about how much privacy we are willing to give up for convenience and security.

Space piracy sounds like something straight out of science fiction, but if humanity builds a large economy beyond Earth, crime will almost certainly follow it. Ships will be carrying fuel, equipment, raw materials, valuable technology, and potentially enormous amounts of cargo between planets, moons, stations, and mining operations. So what would piracy actually look like when there are no oceans, no hidden coves, and every maneuver is governed by orbital mechanics?

In this episode, we explore how space pirates could realistically operate, what they might target, and whether hijacking a spacecraft would even make economic sense. We look at how pirates might intercept cargo ships, raid isolated stations, steal propellant or valuable materials, sabotage infrastructure, smuggle goods, or hold ships and crews for ransom.

We also get into the practical problems pirates would face. Spacecraft are difficult to approach unnoticed, changing orbits requires large amounts of energy, and there may be very few places to hide. A pirate ship would need fuel, maintenance, supplies, safe ports, and some way to sell whatever it steals without immediately revealing where it came from.

Then there is the question of law and enforcement. Who has jurisdiction when a crime happens millions of kilometers from Earth? Would governments create space navies or coast guards? Would corporations hire private security? And could piracy become a serious problem along heavily traveled routes between Earth, the Moon, Mars, asteroid mines, and future space settlements?

From orbital mechanics and spacecraft design to economics, smuggling, law enforcement, and the realities of living in space, we break down what space piracy could actually look like—and whether the pirates of the future would resemble the ones we see in science fiction at all.

What would actually happen if humanity made first contact with intelligent alien life, and would discovering an advanced extraterrestrial civilization unite us, divide us, or completely change our future?

In this episode, Jacob and Lucas explore several very different first contact scenarios, starting with what may be the most realistic: detecting a technological civilization 50 or 100 light-years away. Even if communication took centuries, simply knowing another advanced civilization exists could completely reshape science, religion, politics, and humanity’s plans for the future.

But things get much stranger if the aliens come to us.

What if a generation ship entered our solar system? What if an alien civilization had faster-than-light travel? Would their arrival unite humanity, trigger a new space race, create new religions, or cause global panic?

We also discuss Dyson swarms, the Fermi Paradox, the Dark Forest hypothesis, alien motivations, first contact in science fiction, and the unsettling possibility that an alien intelligence might not consider humanity important enough to communicate with at all.

First contact might be the greatest discovery in human history. The bigger question is whether humanity would be ready for it.
