Introduction: Why I Had to Write About This Book
Every so often a science book lands that doesn’t just explain the world—it shakes it. The Infinite Push: Closed-Loop Pulse Propulsion and the Physics of Self-Sustaining Motion is that kind of book. Written by Michael Lewis, it doesn’t just argue for a new way to think about propulsion; it rips open the black box, invites you inside, and dares you to ask what you’ve always been told not to.
This post isn’t a puff piece. It’s a guided tour: what this book is, what makes it different, what you’ll learn, and why—if you care about science, invention, or just the art of questioning the world—it deserves a spot on your desk.
What Is Closed-Loop Pulse Propulsion?
Let’s start with the core. For decades, the “rocket equation” and Newton’s laws have reigned supreme: if you want to move, throw mass. Action, reaction. The world says “there are no free lunches”—and definitely no self-pushing machines.
But what if that’s not the whole story? Not magic, not a violation of energy or momentum, but something subtler: what if, by cleverly arranging geometry, timing, and feedback, you could get a real “push” from a closed system, without cheating physics?
That’s the question Michael Lewis takes on. The “closed-loop pulse propulsion” (CLPP) at the heart of the book isn’t fantasy, nor is it a perpetual motion machine. It’s a meticulously argued, hands-on exploration of how energy, momentum, and clever design might still hold surprises.
How the Book Works: A Guided Workshop, Not a Lecture
From page one, you’ll notice something’s different. Lewis doesn’t write like a textbook author or a clickbait science guru. He writes like a builder, a questioner, and—maybe most of all—a fellow skeptic.
No Jargon. No Hype. No Bull.
You’re not given claims; you’re given metaphors, stories, and experiments. If you ever wondered what it would be like to have Feynman, Adam Savage, and a mischievous high school physics teacher in the same room, this is that experience.
Key Metaphors That Will Stick With You
1. The Shotgun in Space:
You’ve probably heard “if you fire a shotgun in space, you move backward.” But what if the platform can move? What if there’s sand? What if there are minions throwing things back and forth? The book explores these scenarios, showing how every system’s “ground” changes the rules—and what’s possible.
2. The Yo-Yo and the Platform:
A yo-yo, a platform, and a clever arrangement of pulleys—these are Lewis’s tools for explaining why how you arrange your energy and momentum matters just as much as how much you have.
3. Minions and Sand:
Sand is never just sand here. It’s a way to track momentum, energy, and reference frames. By the time you finish the “minions and sand” thought experiment, you’ll see why so many “impossible” machines are just moving the problem around—but not always in the way you expect.
What You’ll Learn (That You Won’t Get Anywhere Else)
- The Law of Conservation of Energy and Momentum (LoCEM):
Lewis makes the core physics accessible, but also questions how we use it. He points out where the usual textbook approach oversimplifies, and where new possibilities emerge.
- Why Most “Reactionless” Drive Critiques Miss the Mark:
Instead of just saying “it’s impossible,” Lewis shows where the real barriers are—and where, with careful thinking, they might be overcome.
- The Stackable Propulsion Principle:
Can you “stack” small effects into big ones? What if you design the system to allow feedback, resonance, or clever timing? The answers will surprise you.
- How Not to Cheat:
The book is full of cautionary tales—every time someone tries to “cheat” energy or momentum, the system grinds to a halt or cycles endlessly. But with honest accounting, you’ll see how systems can still do surprising things.
- Philosophy as Engineering:
This isn’t just mechanics; it’s a meditation on what it means to try, to fail, and to keep building. You’re invited to join in—not as a passive reader, but as an active participant.
Why This Matters
Physics doesn’t move forward by accepting limits—it moves forward by finding out where those limits really are. The Infinite Push isn’t just about propulsion; it’s about the scientific method at its wildest and most honest. Lewis refuses to take the easy answer, and dares the reader to do the same.
If you’ve ever read a physics book and thought, “but what if...?”, this is the book for you.
What the Critics (and the Curious) Will Ask
Isn’t this just perpetual motion with new branding?
No. The whole book is a refutation of “energy from nowhere.” Everything comes back to conservation laws—sometimes in ways that are less obvious, but always real.
Does it work in practice?
Lewis is candid: not every scheme will pan out. But the experiments, models, and equations in this book give you the tools to test for yourself.
Will I understand the math?
If you can follow a recipe or a well-told story, yes. The math is always explained, and never for its own sake.
Who Should Read This Book?
-
Tinkerers, builders, and inventors
-
Skeptical physicists with an open mind
-
Science teachers and students hungry for new ways to explain old ideas
-
Anyone who wants to see what happens when you question “impossible”
-
Anyone tired of physics writing that’s all “sizzle” and no steak
Final Thoughts: A Book That’s an Invitation
The Infinite Push isn’t a book that preaches. It’s a book that asks. If you want to feel what it’s like to think on the edge, to design with both skepticism and creativity, and to rediscover the fun at the heart of science—buy this book, read it, argue with it, and then go build something.
If you do, let Michael Lewis (and the rest of us) know what you find.
Because the only real “closed loop” is the one between ideas, experiments, and the community that cares enough to test them.
You can find The Infinite Push wherever good books are sold, and at https://www.smashwords.com/books/view/1792786 . If you’re ready for a different kind of physics, this is the place to start.
Sample:
Chapter 1
Closed Loop Pulse Propulsion
I think I finally understand the approach necessary to explain this concept. I honestly don’t believe the physics are hard to understand—more so than they are hard to believe. It took a while to piece together, but the major stumbling block boiled down to two laws.
Well, they’re sort of the same law in a way—at least that’s how I see it, because if you break one, you’re definitely breaking the other.
The Law of Conservation of Momentum
The Law of Conservation of Energy
Or, to put it in words everyone has heard before: "You can’t get something for nothing."
These laws are LAWS. They are inviolate. Unlike human laws, you CANNOT break these. It is impossible. So, if a process breaks these laws even logically, then there is no need to break down the dynamics. The idea is impossible.
For example:
If I want to move a boulder up a hill, I would calculate all the force necessary to move that boulder up that hill and then ensure I have enough fuel to achieve that goal. If it takes 100 joules (which is 100 individual units of work) to get that rock to the top, then I need to provide at the very least, 100 joules.
But here’s the thing—I’m probably going to need a lot more than that, because that’s not accounting for friction and other inefficiencies.
The Law of Conservation of Energy tells me:
If I don’t supply at least 100 joules + inefficiencies, that rock isn’t making it up the hill.
If I only provide 99 joules, sure—the rock will move partway up—but it won’t reach the top.
And once I run out of fuel?
The Law of Conservation of Momentum tells me exactly what happens next:
Whatever goes up, must come down.
That means after wasting 99 joules, I get to watch the rock roll back down and slowly come to a stop.
Why is that?
Gravity and friction.
Gravity is a force pushing down on the rock while you push up on it.
You use an inclined plane to distribute the force over a longer distance.
But in doing so, you introduce friction, which slows it down.
It feels easier to roll the rock uphill than to lift it straight up—but that’s an illusion. Lifting induces no friction, while rolling adds it in. Either way, the principle is the same:
If I don’t supply enough energy to accomplish a goal, I can’t accomplish that goal.
It also means that as long as I keep holding the boulder straight up, it will stay up. That’s what it means to have energy conserved. Conserved can mean stored up, like a battery. I’m storing the energy of the stone in my body, just like a battery stores energy from a wall charger for later use.
But conserved also means something else. If something is in motion, it will stay in motion—unless acted upon by an outside force. So, if I drop the stone, gravity—which is always there, always pulling—Thrusts the stone toward the ground. It never stops Thrusting.
The only thing that stops the stone’s constant acceleration is an outside force—the ground. And that’s something you need to remember later:
Gravity Doesn’t Just Pull—It Stacks
Each split second you’re falling, gravity doesn’t stop pulling. In fact, it pulls you faster and faster, harder and harder toward the ground. That’s what it means to stack pulses. Each pulse of gravity accelerates you more and more, stacking on top of the last. It’s not a one-time force—it’s cumulative.
In Space, This Works the Same Way
Nothing changes—except scale. Just like Earth’s gravity pulls you down, in space, everything pulls on everything else. The difference? That pull is so minuscule that it can’t overcome your inertia. And that’s why you can’t move in space without pushing off something. This is the Conservation of Momentum in action.
I actually think it’s a bit more complicated than that, but that’s a discussion for another day.
The Infinite Drift – Pushing Something Away in Space
Everything in space works exactly the same—but the effects are way more pronounced. It’s true that if you push something away from you, it will keep moving forever. Well—not entirely forever. Eventually, it’ll join up with another mass somewhere, but you get the idea.
More importantly—when I push the stone away from me, it pushes back on me. That’s recoil.
The Shotgun in Space – Recoil in Action
Now, imagine I’m holding a double-barreled shotgun in space.
You pull both triggers—BAM, BAM—
The gun slams into your shoulder and you go flying backward, just like in the movies—Only this time, you never stop.
You’re now moving at a certain velocity, and if you really wanted to, you could do the math to figure out exactly how fast. That’s an easy one, even I can do it. It’s just F=ma. You rearrange the formula and solve for a.
Simple, right?
Don’t Worry About the Math (For Now)
If you don’t understand that, don’t worry. Most of the time, I don’t either. That’s why I use AI to help me with it. But I’ll explain it real quick, just so you’re not completely lost. What F=ma really says is: An object’s energy is equal to how big it is times how fast it’s going. That’s easy to understand. A car going 90 mph has more energy than a pebble going 1 mph.
But here’s an important note: It doesn’t really say that. What it actually says is the mass, which isn’t just weight or size—it’s both, plus density. And that gets multiplied by acceleration—which is a vector force, meaning it has both speed and direction. You don’t need to fully understand that right now—but just know: This basic distinction matters.
The Shotgun in Space: Understanding Recoil and Thrust
So, when you fire the shotgun in space, the explosion pushes you one way and the slugs the other way. That’s simple enough. Thrust, Equal and opposite reaction, this is the key to understanding Step 1 of CLPP.
Shotgun Experiment: Gas Expansion vs. Slug Propulsion – What Actually Moves You?
Let’s tweak the experiment. Forget the slugs for a second. Imagine if I just ignited the gunpowder inside the chamber without a slug. What happens?
I still move.
Why? Because when the gunpowder explodes, the gasses expand violently and are only given one way to escape—out the barrel. And here’s the rule you need to remember:
Every ounce of momentum in those gasses must be accounted for.
If the gasses are all directed one way, then they are accelerating linearly in that direction. And the equal and opposite reaction? You accelerate linearly in the opposite direction.
That alone is enough to push you—even without the slug. The difference between just firing gas and firing a slug is where the force gets applied. When the gasses try to escape, they aren’t just fleeing into space—they are hitting the back of the slug first. That’s resistance.
The gasses push the slug forward and, in doing so, they also push against the gun. And since you are holding the gun, that force transfers to you, pushing you in the opposite direction.
Here’s what that means: It’s not the slug that you are pushing off of. It’s still the explosion causing all the momentum. But when the explosion collides with the slug, that reaction is added to your backward momentum. Now, we’ve amplified the effect.
How This Affects F=ma
We started with a certain outcome—just firing the gas. Then, we interacted with that equation by putting a slug in the way. Now, instead of just accelerating a tiny bit of gas mass, we’re accelerating a slug—more mass, moving faster. Since we have more mass accelerating linearly, the equal and opposite reaction also has more force applied to you. And it has only one place to go—your shoulder.
The Critical Takeaway – What Recoil Really Is
Here’s where most people get this wrong. We are not pushing off the back of the slug. Not initially. Instead, we are being propelled in one direction by the explosion. The slug is being propelled in the opposite direction by the same explosion. When the momentum of the explosion collides with both—
That is the main Thrust event.
That’s the major difference between thrust and just “throwing” something. Both the slug and you are resisting the explosion.
You have inertia—you don’t want to move.
The slug has inertia—it doesn’t want to move either.
The explosion pushes you one way and the slug the other, creating an equal and opposite reaction. And this is what recoil is.
Thrust vs. Torque – Why This Matters for CLPP
In space, you can’t just sling objects away in an arc and expect movement. That’s torque, not thrust. Torque is when you are prying the mass away from the platform with an arm and an anchor point. Thrust is when you are pushing the mass straight away from you as fast as possible. And for CLPP? We need thrust.
Locking in Step 1 – What Thrust Actually Is
Let’s go over it again, but this time, let’s focus on Thrust. I hope by now you see the difference in what I’m suggesting.
I’m saying that you, the platform, simply have to push off the slug. That’s it. You just push a mass away from you to achieve Step 1 of CLPP.
If you’re the platform, you need energy and some device in between, pushing both you and the slug away from each other. That’s all thrust is.
Recoil, Impact, and Unfortunate Thrust
If you push something away, it pushes you away. Equal and opposite. Basic. But here’s what’s just as important:
If you catch something, it must be going faster than you, and when it hits you, it gives you Thrust in the opposite direction.
Think about the guy getting blasted by the shotgun—
That’s Unfortunate Thrust.
If the impact is in the opposite direction of your movement, it subtracts from your momentum.
If the impact is hitting you from behind, it adds to your momentum.
If it hits you from the side, it throws you into a new vector entirely.
This isn’t complicated, but it is crucial.
Why Rocket Fuel Sucks as a Propulsion Method
Let’s talk about rockets for a second. Rocket fuel explodes, and that explosion pushes you away from the gasses. That’s all it does. And it’s not a great way to go. The trick with Thrust is to align all momentum so you get the most out of every reaction. That’s why rockets have nozzles—to force the explosion’s energy into one concentrated direction so it can push the heavy-ass spaceship in one direction.
But what if we could do something better? What if we didn’t waste all that energy just by burning through expendable fuel?
The Anvil Rocket – A Thought Experiment
Imagine if a rocket carried unlimited anvils. Every time it fired, it detonated fuel between anvils, launching them away from the ship at high velocity. That would be the ideal propulsion system. Each reaction is purely linear—every push is clean and directional.
But there’s a problem. You’d eventually run out of anvils, just like you eventually run out of fuel. And that’s why rockets suck. They’re always burning mass to move forward. But CLPP doesn’t waste mass—it reuses it. That’s the difference.
Why an Anvil Would Be a Better Propellant than Fuel
The reason an anvil would be a better propulsion system than rocket fuel is simple: With an anvil, the equal and opposite reaction is purely linear. With fuel, the explosion spreads the force outward, sending energy in all directions. Rocket engineers have gotten better at shaping that energy flow, but it’s never perfect.
It’s important to note:
They are not pushing off the air.
They are not pushing off the ground.
Well… initially, they are, but once they hit space, the air disappears. And there’s also the ever-decreasing effect of gravity—though Thrust works independent of any outside force. In fact, you don’t need friction. You don’t even need an explosion.
All you need?
You just need to push one thing away from another.
The Giant Stack of Anvils Experiment – Space Edition
Now, let’s really have fun with this. Get in your spacesuit. We’re grabbing a giant stack of anvils. We’re going outside. You step onto a massive platform—floating out in the void. There’s no gravity. No friction. Nothing at all.
The platform is huge—but don’t worry. You have magnetic boots, so walking around won’t disturb the platform too much. But what does that really mean?
The Raft Analogy – How Size Affects Motion
Think about a small raft—something the size of Huck Finn’s raft, floating on a tranquil lake. Now, if you try to walk forward on the raft, every step you take pushes the raft backward. Now imagine instead of a small raft, you’re on something the size of an aircraft carrier. You can step forward, and technically, it still moves—but your steps are insignificant compared to the sheer mass of the carrier.
In space, that’s even more pronounced. If you’re on a small platform, even the act of shifting your weight can start the whole thing moving. If you’re on a massive platform, you can jump, run, throw anvils off of it—And you’ll barely notice a thing. But the key to CLPP is realizing how to make those forces work for us—not against us.
Momentum, Impact, and Platforms in Space
Let’s break this down with a simple thought experiment: I’m floating in space on my rocketship. And I decide—because why not—to fire an asteroid at your rocketship. Now, what happens next depends on a few things:
The mass of the asteroid.
The velocity I fire it at.
The angle and location of impact.
Your rocketship will react differently depending on whether I fire a tiny pebble or a massive asteroid. But here’s the thing: It’s not just about size.
If I fire a tiny pebble at insane speeds, it might push your ship more than a slow-moving asteroid would. That’s just F=ma at work again. Regardless of which object I fire, here’s what happens:
If the pebble or asteroid gets lodged in your ship, you now carry that mass with you. That means we have to combine the total momentum of the object with your rocketship. That’s the Law of Conservation of Momentum at work. Your ship has to react equally and opposite to the impact, proportional to the size, speed, and direction of what hit you.
Even if I just fling a booger at you, your rocketship will react accordingly.
If I flick it slowly, it’s negligible.
If I flick it fast enough, you will move.
If a race of giant aliens attacks us with massive boogers, well… don’t say I didn’t warn you.
The Overlooked Part – My Rocket Also Moves
Now, here’s what the movies don’t show you: When I fire that asteroid, pebble, or even the booger, my rocketship moves too. That’s recoil.
The force that pushed the asteroid away also pushed me backward. People who’ve served in the Navy already understand this concept. I don’t know that for certain—but I know it for certain.
Two Equal and Opposite Reactions – Not One, But Two
This is vital to understand:
When I fire something at your ship, there are two reactions happening at the same time:
Your rocketship reacts when the object hits you.
My rocketship reacts when the object leaves my platform.
It’s not just about you moving—I move too.
And this isn’t just some small effect. If your rocket is tiny and mine is massive, then yes—when I fire an object at you, you move way more than I do. If I shoot a projectile straight at your chest, you’re going to feel it.
If your ship is small, you move backward fast.
If your ship is big, you still move, just not as much.
Size does matter.
And now I’m beginning to see why the Navy got its reputation.
Platforms in Space – Scaling Recoil and Motion
Let’s shift back to platforms and avoid any unnecessary innuendo. If you are walking around on a small platform in space, each step you take will push the platform slightly backward. If you’re walking on a huge platform, it barely moves at all. Let’s make sure this logic holds:
✅ You have a platform the exact same size as you.
If you push it away, you and the platform move equally in opposite directions.
If you’re tethered to it and push off, the tether pulls you both back together.
✅ Your platform is twice as big.
When you push off, it moves half as much as you do.
✅ Your platform is massive.
When you push off, it barely moves at all.
✅ Your platform is smaller than you.
It moves more than you do.
Fair?
Tethered Platforms – Experiments in Motion
Now, let’s make this interesting. I want you to imagine a massive platform floating in space. You push off of it—but instead of floating away forever, you’re attached by a tether. And this tether? It lets you spin. Now we get to the fun part. We’re going to do some exercises with the tether, and I want you to follow along.
The Tether Exercises
First Exercise: The Bungee Snapback
You push off the platform. The tether stretches out, pulling tight, and then—SNAP. It yanks you back, fast, like a paddle ball returning to the racket. Now, here’s the question:
Do you return to the platform at exactly the same speed you left it? There’s doubt in my mind, so for argument’s sake, let’s assume a perfect system with zero inefficiencies—no air resistance, no stretching losses, no friction.
You push off with one force.
The tether stretches, storing energy.
The tether contracts, snapping you back harder than before.
That feels right, doesn’t it? The snap has to bring you in harder, like a spring pulling back. Except… it doesn’t. That would violate the Conservation of Energy and the Conservation of Momentum. You can’t get out more than you put in. The spring doesn’t add energy—it just changes its shape.
By the time you reach the platform, all that stored energy has been fully converted back—and you’re right back where you started. Your center of mass changed, the platform’s center of mass changed, but as a whole system, nothing moved. You have gone nowhere.
Second Exercise: The Hard Tug
Okay, same setup. Same bungee tether. Same push-off. But this time, when the tether reaches full extension, you yank on it hard. What happens? Do you return at the same speed?
No way.
That would be a clear violation of—okay, I’m abbreviating this—LoCEM. Since you added energy, you must account for it. By doing work on the system, you have added energy and momentum that must be accounted for. And it is—it becomes zero when you stop against the platform. LoCEM remains conserved.
But let’s put a pin in that for later—because the work required to turn an object is called Torque, and it’s about to become really important.
Third Exercise: Changing the Tether – Stopping in Space
Now, let’s swap out the bungee tether for a different type of tether. This one is designed to absorb your momentum and stop you at a fixed distance from the platform. You push off. You travel 20 meters out—and then, you stop.
Both you and the platform are now stopped. Zero momentum. At first, you just float there—like a marionette on a string, weightless and frozen. Then, you start flailing around. And after a few seconds, you realize something. You can spin yourself around—without pushing off anything.
You start slow, like a kid on a swing.
You shift your weight, and the motion builds.
You spin faster—because there’s nothing stopping you.
Now, imagine you had a weight on a rope. If you start slinging it around, that’s going to make you spin even faster. Think about a tetherball.
You start it swinging.
It wraps around the pole.
The tighter it winds, the faster it spins.
Now, imagine an ice skater.
Arms outstretched—they spin slowly.
Arms pulled in—they spin faster.
The tighter the radius, the faster the rotation. Now, here’s something wild:
A super-thin ice skater with freakishly long arms and legs could, mathematically, spin faster than anyone else. Not because of talent. Because of pure math. You will never spin faster than your arms and radius allow. But you can and will spin if you want to.
Fourth Exercise: The Spinning Lunatic
Same tether, same stopping point. Except this time, we zoom out—and you’re watching me. I’m out there, spinning like a lunatic. And from your vantage point back in the ship, you’re wondering the obvious:
Is anything I’m doing affecting the platform’s motion?
Can I force the platform to move just by spinning faster?
At what speed does my ridiculous, vomit-inducing spin make the platform rocket away?
The answer? It doesn’t. No matter how fast I spin, I’m not going anywhere. In order for me to move linearly, I have to to have thrust. But in order for the platform and I to stop—for me to drift away from the platform and just float there—the platform had to move just slightly. It’s not noticeable, but it had to happen.
And if you look really closely, you’ll see that at best, the only real effect I could possibly have on the platform is turning it slightly.
Whoa!
Right.
Let’s talk about that later—because that’s going to blow your hair back. For now? We’re still in Step 1.
Exercise 5: The Yo-Yo
Same tether, same setup—but now, it’s about to get weird. You wrap yourself completely in the tether, coiling it all around you. Tightly.
You're now a spinning yo-yo. But this time, you push off HARD. Like Superman-level leg strength hard.
You explode away from the platform, spinning like a human gyroscope as the tether uncoils beneath you. The platform pushes back, recoiling from your launch. For a moment, it’s beautiful. Momentum perfectly conserved.
The tether stretches—more and more—until… DOING!
Momentum reverses, and you and the platform collide head-on, stopping dead.
Damn it. That didn’t work.
This time, HARDER PUSH.
You roll out like a spool of thread.
You’re not gaining much more rotational speed.
You’re not moving away much faster.
Wait, what’s happening?
The tether is just unrolling faster and faster.
First from your waist, then your feet.
And suddenly—SNAP!!!
The tether breaks.
Now, what happens?
You’re still spinning.
The platform is now forever disappearing into the void.
You’re moving away both linearly and rotationally.
That sounds horrible—but also kind of poetic in a tragic way. But don’t panic. I will get you back in Step 3.
Did you really think I was going to leave your spinning ass floating off into space? Don’t stress it.
But you ARE going to need Dramamine. It’s going to take a minute. Because you still have so much to believe that you already know.
