Entropy Rising

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...

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...

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...

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, ci...

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

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...

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...

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...

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?

Support Entropy Rising on Patreon: https://www.patreon.com/c/EntropyRising

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 th...

Simulation theory, the Fermi paradox, the Zoo Hypothesis, alien civilizations, digital consciousness, and Matrioshka brains all raise one strange possibility: what if advanced civilizations stop exploring space and choose simulated realities instead?

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

In this episode of Entropy Rising, we explore whether simulation theory could offer an explanation for the Fermi paradox and why we still haven’t found evidence of advanced extraterrestrial civilizations.

Could humanity itself be living inside a simulation? Could an advanced alien civilization place developing species inside simulated worlds as a...

Could genetically engineered humans be the key to colonizing Mars and exploring deep space? In this episode of Entropy Rising, we explore genetic engineering, transhumanism, human augmentation, Mars colonization, and the future of space travel to ask a strange question: instead of terraforming other planets, could we redesign humans to survive them?

Humans evolved for one very specific environment: Earth. Space exposes us to radiation, low gravity, extreme temperatures, toxic dust, and environments where we simply cannot breathe. But future advances in biotechnology and cybernetics could potentially change that.

Orbital rings might be one of the most practical megastructures humanity could eventually build. They could provide cheap access to orbit, move massive amounts of material between Earth and space, and avoid many of the problems that come with space elevators.

In this episode of Entropy Rising, we break down how orbital rings actually work, why they don’t require impossible materials, and how an actively supported ring around a planet could become the backbone of a future spacefaring civilization.

We also explore how orbital rings could use elevators and magnetic launch systems to move pe...

How realistic is the science behind Project Hail Mary?

In this episode, we break down Astrophage, its incredible energy density, its ability to dim a star, and whether biology could ever evolve something that extreme. We also explore Rocky’s high-pressure world, xenonite, panspermia, photon-powered spacecraft, and what humanity could do to survive if the Sun suddenly lost 10% of its brightness.

From alien biology to interstellar engineering, we examine which ideas are grounded in real science, which require major assumptions, and why the story still feels surprisingly plausible.

Shell Worlds and Birch Worlds are some of the largest megastructures ever imagined, offering a vision of artificial planets that could support civilizations ranging from a single family to trillions of people. From hollow planets filled with hydrogen to colossal Birch Worlds built around supermassive black holes, these concepts push the limits of engineering, physics, and the future of space colonization.

In this episode of Entropy Rising, we explore how shell worlds could be constructed, why an advanced civilization might choose to build artificial planets instead of living on natural ones, and how these incredible structures compare...

What does it really take to survive interstellar travel? As future spaceships approach light speed, even a tiny grain of interstellar dust becomes a devastating collision, forcing engineers to rethink everything we know about spacecraft design, radiation shielding, and relativistic travel.

A grain of dust no larger than a speck of sand could strike with the energy of a nuclear weapon when you're traveling at a significant fraction of the speed of light. That means every future starship will need far more than thicker armor if humanity is ever going to reach another star.

What if rockets became obsolete? Space elevators could be the megastructure that transforms humanity into a true spacefaring civilization—if we can solve the material science and engineering challenges. In this episode of Entropy Rising, we break down how space elevators work, why advanced civilizations might depend on them, the carbon nanotube problem, and whether this is realistic engineering or pure science fiction.

Welcome to Entropy Rising, a science and futurism podcast that explores humanity's future through the lens of real physics.

Each week, we dive into ambitious questions about our universe. Could we build space elevators or Dyson spheres? How might we travel to other stars? Why haven't we found intelligent life? What technologies could shape civilization over the next century—or the next million years?

Rather than treating these ideas as science fiction, we examine what modern science says is possible, what remains speculative, and what the future could hold if humanity continues to push the bo...

Humanity's expansion into the outer Solar System won't look like science fiction imagines. Instead of building cities on frozen moons, our first civilizations beyond Mars may live inside enormous rotating space habitats orbiting Jupiter and Saturn.

In this episode of Entropy Rising, we explore what life beyond the asteroid belt could really be like. We discuss asteroid mining, O'Neill cylinders, cycler spacecraft, the economics of deep-space settlements, how entirely new cultures could emerge around the gas giants, and why someone born near Jupiter might go their entire life without ever meeting a person from Earth.

How will humanity feed billions of people on Earth—and eventually millions more in space?

In this episode of Entropy Rising, we explore the past, present, and future of agriculture. From AI-powered tractors, autonomous drones, and laser weed killers to vertical farming, hydroponics, lab-grown meat, and orbital agriculture, we examine how one of humanity's oldest industries has become one of its most technologically advanced.

We discuss why only a tiny fraction of the population now produces food for everyone else, how automation transformed farming long before AI, and what future food production might look like in...

Are we alone in the universe… or are we being intentionally isolated from it?

In this episode of Entropy Rising, we dive into one of the most unsettling solutions to the Fermi Paradox: the Zoo Hypothesis. The idea is simple but disturbing. Advanced alien civilizations may already know humanity exists and are deliberately avoiding contact.

But why?

We explore the different versions of the theory, from civilizations observing us like animals in a cosmic nature documentary to galactic “prime directives” that prevent interference with developing species. We also discuss whether humanity is actually too da...

Humanity might not just be early to the universe… we may have to be early.

In this episode of Entropy Rising, we dive into the Grabby Aliens theory, one of the most fascinating solutions to the Fermi Paradox. The idea is simple but unsettling: if intelligent civilizations tend to expand across the stars, then any civilization born too late would never get the chance to exist at all.

We explore:
• Why expansion may be a natural outcome of evolution
• How civilizations could spread across the galaxy in only a few million years
• Whether...

What happens when surviving your planet isn’t enough… and even your star starts to die?

In this episode of Entropy Rising, we explore what it would actually take for a civilization to survive for billions, trillions, and even longer. Not just avoiding extinction, but pushing all the way to the edge of the universe itself.

We break down real, physics-based ideas like restarting a planet’s core, shielding worlds from solar death, harvesting and extending the life of stars, and eventually moving beyond planets entirely. From Dyson swarms to artificial black holes, this is the lo...

Venus colonization isn't science fiction—it's closer to reality than Mars. In this episode of Entropy Rising, we explore why floating cloud cities in Venus's upper atmosphere could become humanity's second home, and what terraforming would actually take. From extremophiles thriving in acidic clouds to the engineering needed to strip away billions of tons of CO₂, discover why Earth's hottest neighbor might be our best bet for solar system expansion.

Humanity, at the center of the galaxy… or just another average species?

In this episode of Entropy Rising, we break down the popular sci-fi idea behind “Humanity, F*** Yeah” (HFY)—the belief that humans would dominate any galactic civilization through sheer willpower, creativity, or grit. It’s a fun concept. It makes for great stories. But how well does it actually hold up when you look at it through the lens of real science?

We explore the assumptions these stories rely on: Are humans uniquely violent? Is our intelligence fundamentally different? Could a younger civilization realistica...

Most science fiction shows sleek, elegant starships—but real spaceships would look very different. In this episode of Entropy Rising, we break down what realistic spacecraft design might actually look like using real physics and engineering constraints.

From massive radiators needed to dump heat into the vacuum of space, to radiation shielding, propulsion limits, and the surprising advantages of long, narrow ship designs, we explore the practical challenges that would shape future spacecraft. We also look at how ships might differ depending on their role—whether they’re transporting people between space stations, hauling cargo across the solar...

Hive minds are not just a sci fi trope. They might be a natural outcome of evolution.

In this episode of Entropy Rising, we explore whether hive minds could realistically evolve in nature and whether advanced civilizations might choose to become networked intelligences. Are the Borg pure fantasy, or is there a biologically plausible path to collective consciousness? Could something like the Conjoiners from Revelation Space represent a more realistic future?

We break down the difference between a true hive mind and a networked intelligence. From ant colonies and pheromones to biological radios and interstellar...

If a civilization can cross interstellar space, the war is already decided.

In this episode of Entropy Rising, we examine planetary invasion through the lens of real physics. No cinematic dogfights. No convenient alien weaknesses. Just propulsion energy, orbital mechanics, and strategic reality.

Any ship capable of traveling between stars already carries extinction-level energy. Once an invading force controls orbit, they don’t need to land troops. They can freeze a planet with solar shades, redirect stellar energy to overheat it, scatter relativistic debris, or enforce a blockade. Gravity favors whoever owns space.

We often talk about the future of space as if it starts on Mars, in the asteroid belt, or among the stars. Giant habitats and interstellar travel dominate the conversation. Those ideas are exciting, but they skip over a much closer and more practical question.

What happens first.

In this episode of Entropy Rising, we focus on the place where humanity is most likely to learn how to actually live in space: Earth’s orbit. This is not an episode about distant megastructures or speculative technology. It is about infrastructure, economics, and incentives. The groundwork th...

Planets are a historical accident. Ring worlds are what you build once you understand physics well enough to stop settling for spheres.

In this episode of Entropy Rising, we break down rotating space habitats from the near term to the absurdly large. We start with practical designs like Stanford tori and early ring stations, then scale up through Bishop rings and Banks orbitals, all the way to full Niven style ring worlds that rival planetary orbits.

We dig into how spin gravity actually works, why small habitats make people sick, where material limits appear, and...

Why don’t we see aliens, even in a universe this big? In this episode of Entropy Rising, we break down the Great Filters and how they help explain the Fermi Paradox. The idea is simple but unsettling. Somewhere between dead matter and galaxy spanning civilizations, most life gets stopped. We walk through the full chain. From the origin of life, to complex cells, multicellular organisms, intelligence, and finally technological civilizations that should be detectable. Some filters may be behind us. Others may still be ahead. We also talk about why simple life might be common why intelligence may be...

In this episode of Entropy Rising, we explore how weapons evolve as technology and energy scale up, starting with systems already reshaping modern battlefields and extending into the kinds of weapons only advanced civilizations could realistically build.

We begin with near-term developments like drone warfare, autonomous systems, and anti-drone countermeasures, looking at why these technologies are changing conflict faster than almost anything else in modern military history. From there, we examine how familiar weapons behave once combat moves into new environments like zero gravity and space, and why many science-fiction staples break down once physics, heat, recoil...

What if cooling the planet isn’t just about cutting emissions, but about reshaping the environment itself? In this episode of Entropy Rising, Jacob and Lucas break down the real science behind climate engineering — from solar shades positioned at L1 to sulfur aerosols, cloud seeding, carbon capture, ocean fertilization, and even the far-future idea of nudging Earth’s orbit with gravity tractors. They explore what’s actually feasible, what’s risky, and how these technologies could shape not only Earth’s future, but the climates of Mars, Venus, and any other worlds humanity might settle. This is climate control at planetary...

Automated probes can mine asteroids, build infrastructure in zero-gravity, and push deeper into the solar system than any astronaut ever could. So the real question becomes: if machines can explore space more safely, cheaply, and efficiently, what role is left for humans? In this episode of Entropy Rising, Jacob and Lucas break down the future of space exploration through a lens most people never think about: the competition between biological explorers and automated systems.

They talk through why robotic probes dominate early missions, how AI-driven mining and construction could reshape the entire space economy, and what a...

Augmented reality isn’t science fiction anymore—it’s quietly reshaping how we see the world. In this episode of Entropy Rising, Jacob and Lucas explore how AR could blur the line between the digital and the physical, creating a world where reality itself becomes optional. They break down the tech behind waveguides and adaptive lenses, how glasses could merge with AI, and what happens when virtual layers start to define our daily lives. From accessibility breakthroughs like live transcription to dystopian nightmares of ad-saturated streets and social credit overlays, the conversation dives into the promise and peril of a worl...

What would it take to turn an entire planet into a factory, a farm, or a fortress? In this episode, Jacob and Lucas explore the concept of dedicated planets—worlds that serve a single purpose within a vast interstellar civilization. From the toxic, molten surfaces of forge worlds that produce endless streams of metal, to the idyllic agri worlds that feed billions, we examine how these ideas from Star Wars, Warhammer 40K, and classic sci-fi might hold up under the laws of physics.

Could Mercury become a real forge world for humanity? Would a galactic empire ever re...

In this episode of Entropy Rising, Jacob and Lucas ask a simple question: could a galactic empire actually work without faster-than-light travel? The answer isn’t pretty. They break down why distance, communication delays, and logistics make ruling across the stars nearly impossible. From the futility of interstellar trade to the idea of technocratic influence and AI-controlled colonies, they explore how any attempt at a “galactic empire” would crumble under the speed of light itself. They also contrast this with solar empires—where power, control, and trade might still make sense within one star system.

What happens when a city doesn’t just sprawl across continents but covers an entire planet? In this episode of Entropy Rising, Jacob and Lucas explore the concept of the ecumenopolis—a world completely urbanized from pole to pole. From the classic depictions of Coruscant in Star Wars and Trantor in Foundation, to the grim hive cities of Warhammer 40K, we dig into the science and engineering challenges of building a planet-wide metropolis.

We break down population math, vertical megastructures, the paradox of elevators, and the role of food, energy, and infrastructure in making such a world func...

What happens when scarcity disappears? In this episode of Entropy Rising, Jacob and Lucas explore the idea of a post-scarcity civilization — a future where food, energy, and even housing are so abundant they stop being economic factors. But does abundance guarantee happiness, or does it create new problems?

We break down the levels of post-scarcity (from basic survival to simulated utopia), question whether inequality and control still exist in an age of abundance, and debate the biggest paradox of all: if nothing is scarce, what still gives life meaning?
