7: The Laws of Thermodynamics
The Gaia Theory is good for people to know about, but it takes a lot of scientific equipment and education to be able to see it happening. So if you don’t have the equipment and education, how can you recognize whether politicians and business people are cooperating with the Gaia Theory or not?
The Selfish Gene Theory isn’t hard to recognize, because all you have to do is to look to see how an animal, or person, or plant, or any other organism, is acting in the attempt to help itself survive and reproduce. Then you can combine that with the first principle of physics to see how the economic system of the universe meets the economic system of life.
The Laws of Thermodynamics are the economic system of the universe. There are four Laws of Thermodynamics. They’re called the Zeroth Law, and then the First, Second, and Third Laws.
The First Law of Thermodynamics was discovered first. Then the Zeroth Law was discovered later, but the First Law depended on the new law, so that was called the Zeroth Law. Basically, the Zeroth Law says that if you have three cups of water and one of them is the same temperature as the other two, those two are the same temperature as each other. If you mix any two or all three together, none of them will exchange heat with each other. All three are thermodynamically equal. This is just a point of reference that establishes something that seems obvious. That’s important in science, because often the things that seem most obvious are the easiest to misunderstand. Then when you base further conclusions on your faulty premise, all your conclusions are wrong. I told you what happened when scientists assumed the atmosphere had always been the way it is—they completely overlooked the Gaia Theory.
You’ve probably heard that heat makes molecules move faster, and molecules slow down when they lose heat. The Third Law of Thermodynamics says that it isn’t possible to cool anything down to the point that molecules stop completely. Scientists and engineers have cooled things down to within a millionth of a degree of that happening, but that last millionth of a degree can’t happen until the end of the universe, because as long as there is still heat anywhere in the universe, it will get into your experiment somehow. If you have a thermometer in a room where you’re conducting the experiment, and a wire connected to the thermometer, and a computer connected to the wire where you’re monitoring the experiment, heat will still get into your experiment through the wire. Or through the walls of the room. One way or another, something in your experiment is still connected to something where molecules are still moving.
I’ve told you how the universe began with the Big Bang. The Third Law of Thermodynamics shows us how the universe will end. It’s called the Heat Death of the universe. Energy moves because there’s more of it in one place than in another. That’s how electricity moves from one end of a flashlight battery, through the resistors in the bulb that heat up and give off light, and into the other end of the battery—because there’s more energy in one end of the battery than the other. That’s why the temperature of two cups of water would change if they were two different temperatures when you mixed the water together—and why the temperature doesn’t change if the two cups of water are already the same temperature.
Matter moves because energy moves it. You could just as easily say that energy is contained in the motion of molecules, atoms, and subatomic particles.
The Heat Death of the universe will happen when all the energy in the universe is distributed equally. When all the energy in the universe is equally distributed, everything in the universe will stop. Time will stop, because there will be nothing left in the universe that’s changing in any way at all. If you could stand there looking at your watch and looking at all the molecules not moving, and looking at the seconds ticking by, you and the second hand in your watch would be the things in the universe that were still moving, so you would not be watching the death of the universe yet.
This sounds absurd, but that’s only because it takes a while to wrap your brain around the idea. No one has ever seen anything that’s similar to the Heat Death of the universe, so no one has anything to compare it to. But this is the inevitable result of the way energy moves through the universe.
The discovery that the galaxies are moving away from each other at an accelerating rate, and therefore the Big Bang wasn’t a simple occurrence that happened at some time in the past, throws some doubt on the original idea of the Heat Death of the universe. But even if energy is still being created in the center of the universe, it isn’t doing us any good out here—because we’re moving away from all that new energy at an accelerating rate!
From this it seems that something like the Heat Death of the universe will occur at the edges of the universe and move inward, as different parts of the universe run out of energy at different times, but are pushed out of the way by the things closer to the center of the universe that still have energy. That wouldn’t be the literal Heat Death of everything toward the edges of the universe, because those things would still be moving. Maybe the Heat Death of the entire universe will never happen, but stars still die, their solar systems die, and entire galaxies die. Enough energy from the center of the universe will reach the edge of the universe to push all the dead galaxies out of the way, but it won’t be enough energy to bring any of their stars back to life.
This scientific version of the birth and death of the universe is useful because in the same way that you can see the story of the origins of life still being told in every living thing you look at, you can see the story of the birth and death of the universe being told in every physical thing you look at.
The First and Second Laws of Thermodynamics create the economy of the universe as it affects us now. Entropy, by Jeremy Rifkin, is a good book about this. It’s shorter than this book and easy to read, but it seems like a completely alien way of looking at the world. He shows how the economic system of the universe affects the economic system of life, but as I’ve said, the economic system of the universe is a big natural blind spot in our perception. But if you stop looking at the world in terms of how you feel the world is supposed to work, and start looking at it in terms of how energy flows through the world, you can see that poverty, famine, pollution, resource consumption, the breakdown of life cycles in the environment, inflation, and many physical and mental health problems in the modern world all follow the same two simple laws of physics.
The first two Laws of Thermodynamics give us a third important frame of reference. With the Laws of Thermodynamics you aren’t jumping from biology to chemistry, you’re jumping from biology straight to physics. Since all of chemistry is physics, from there, everything that applies to physics automatically applies to chemistry.
The Laws of Thermodynamics are the most fundamental laws of the universe. That makes them an easy point of reference because any time you talk about anything happening anywhere in the universe, you’re talking about the Laws of Thermodynamics.
The First Law of Thermodynamics says that matter can never be created or destroyed; it can only change form. That means the total amount of energy available in the universe is finite. In order for the energy in the universe to be infinite, the universe would have to be infinitely large or infinitely hot, neither of which is true. Even if more energy is being created in the center of the universe, the amount of energy available in our part of the universe is finite for all intents and purposes.
The Second Law of Thermodynamics states that the total entropy of the universe tends to increase. In plain English, that means matter and energy always move from areas of high concentration to areas of low concentration more than they move from areas of low concentration to areas of high concentration.
The most practical way to word these two Laws of Thermodynamics goes: “The total amount of available energy in the universe is finite and decreasing.”
Any time anything happens, anywhere in the universe, it requires energy. That’s because making things happen always requires atoms, or at least, subatomic particles, to be moved from one place to another. Making atoms move requires energy.
Any time energy is expended, some of it radiates out into the universe as heat. That means it’s gone forever, because the heat gets soaked up by outer space.
If you eat a sandwich and then go running, you’ll use the energy from the sandwich to make your legs move, and then most of the energy will radiate off of you as heat, out into the atmosphere, and eventually, off of the Earth. If an alien astronomer was looking at the Earth with an infrared telescope, some of the heat he would see would be the energy that was once contained in your sandwich.
A battery works because it has a higher charge of electrons in one side of the battery than the other. When you put the battery in a flashlight, the electrons flow out one end of the battery, through the flashlight, and into the other side of the battery. When the electrons are equal in both sides of the battery, the battery is dead, because electrons—meaning electricity—won’t flow from one side to the other anymore.
The entire universe works the same way. The energy in your sandwich was more highly concentrated than the energy in outer space, so the energy flowed from the area of highest concentration to the area of lowest concentration.
Matter also moves from areas of high concentration to areas of low concentration. When my dad was maybe 6 or 8, his mother bought a paring knife. When I was 27, she still had the same knife. She had sharpened it so many times the blade was only about 1/4” wide anymore. That happened because every time she sharpened the knife, she wore knife-molecules off of the blade, and they became distributed more evenly throughout the universe.
This happens to everything in the universe. Everything wears out eventually. It happens to the front doorstep of your house. It happens to your carpet. It happens to your shoes. It happens to your clothes. It happens to your car. It happens to you.
Your carpet and the front doorstep of your house get worn down over time because the friction from walking over them breaks molecules loose and they turn into microscopic dust that you can never reclaim and reattach to your carpet or your front doorstep. Your carpet doesn’t get thicker the more you walk on it; neither does the front doorstep of your house.
Likewise, your favorite pair of shoes weigh less now than they did when you bought them new. The soles are thinner also. You get holes in the knees of your favorite pants by wearing them. Wearing your favorite pants doesn’t make the holes in the knees disappear. Your car wears out and breaks down the more you drive it and the older it gets. Driving your car more doesn’t make it run better. Likewise for you. In your peak reproductive years, you’re the healthiest you’ll ever be. Then your body deteriorates until you die of old age, unless you die from other causes prematurely.
I refer to the Laws of Thermodynamics in terms of available energy being finite and decreasing because that’s the inescapable problem. It is conceivable that someone could build a machine for collecting microscopic dust particles and reattaching them to whatever they came from, but that will never be practical because it would take energy to power the machine. Putting that energy into the machine would create more microscopic dust than the machine collected. Operating the machine would be completely counterproductive.
In the same way, I’ve heard people ask why we can’t save the environment by shooting all our pollution off into space. Lifting anything up out of the gravity of the Earth into outer space takes a lot of energy. Refining that rocket fuel and then burning it would create more pollution than you were eliminating.
When the energy from your sandwich radiated out into space, it was gone forever, because it had moved to the area of lowest energy concentration in the entire universe (or at least, the entire universe that we know about). There is no machine you can build to reclaim your sandwich energy from outer space, because it would take more energy to power the machine than there was in your sandwich.
At every point of building your hypothetical machines, matter and energy would be lost. Mining the minerals to build the machines would take energy and would distribute a lot of matter and energy throughout the world more evenly. Collecting the fuel to power the machines would do likewise. When you used the machine, it would wear out over time, molecules would break off, and they would scatter throughout the universe more evenly as microscopic dust. Mining the minerals to build spare parts for the machine would scatter matter and energy more evenly throughout the universe. And so on.
Now here’s where the problems begin. The economic system of life depends on certain kinds of energy and matter being concentrated in certain places, but the physical economy of the universe works exactly opposite that.
If there were no people in the world, this wouldn’t be a problem. As I showed you with the Gaia Theory, everything in the world is part of the life cycle of something. Plants and animals depend on certain kinds of matter and energy being concentrated in certain places for their lives, but whatever comes before them in the food cycle does that for them. Plants soak nutrients out of the atmosphere and soil, they concentrate matter and energy for herbivores, by eating the plants the herbivores concentrate matter and energy for carnivores, and so on. Whenever a plant or animal dies, it leaves a lot of matter and energy concentrated in one place that bacteria and bugs and fungus eat, and so on.
Matter keeps moving around in the global environment, but it doesn’t get added or removed from the environment. It’s energy that gets added and removed from the global environment. All the energy that powers the food cycles of the world comes from the sun (and a little geothermal heat). When plants absorb sunlight, they use it to grow. That means they use the energy to bind the atoms of the nutrients from the soil and atmosphere together to create the big new molecules that make the plants grow. Some of that energy gets stored in the molecular bonds of the new plant-molecules. When the herbivore eats the plant and digests the food, it releases the energy from the molecular bonds—which is where the herbivore gets its energy. It also breaks up the plant molecules and turns some of them into new molecules that become its body mass—which is how the animal grows and maintains its health. And so it goes when the carnivore eats the herbivore.
At every step of this process, energy is radiating off of the Earth—meaning out of the environment. But it’s continually being replaced by more energy from the sun. Energy is leaving the environment, but more energy is replacing it at the same rate. Energy is continually moving from areas of high concentration to areas of low concentration faster than it moves from areas of low concentration to areas of high concentration because the sun is gradually running out of fuel. But as far as the Earth is concerned, the environment had a permanent, constant supply of energy.
Humanity is throwing all of this off for the simple reason that we have the ability to remove matter and energy from environmental cycles, and there’s nothing else on Earth that can counteract what we do. The environment can adapt to the new distribution of matter and energy, but that takes time. If we extract matter and energy from the cycles of the world too fast, the environment won’t be able to keep up.
Pollution is matter that accumulates in the environment that doesn’t serve any further use to the cycles of the world. Either the cycles of the world can’t reclaim it as fast as it’s being produced, or else they can’t reclaim it at all. Some types of pollution, like CFCs, actively destroy more of the environment after humans dispose of them.
Environmental destruction is all pollution of some form or another, even if it isn’t the waste products of anything humans have used directly. It could be the direct results of something humans did in the process of making use of other matter and energy, or it could be something that happens as an even more indirect result of something people have done. In any case, matter and energy are always moving from areas of high concentration to areas of low concentration. In the process, matter and energy are moving out of the natural cycles that were using them before, and aren’t moving into new natural cycles. The net result is that human activity is causing the natural cycles of the world to break down.
For instance, if you mine copper, you have to dig a lot of rocks out of the ground to get to the rocks with the copper ore in them. You end up with a big pile of rocks lying outside your copper mine. When those rocks were buried underground, they were fulfilling a critical role in the natural cycles of the world, and now they aren’t anymore. Specifically, they were holding a lot of arsenic underground, and out of the rest of the environment. Now that you’ve dug all those arsenic-laden rocks out of the ground and left them lying on a hillside, the next time it rains, a lot of arsenic is going to be washed off of the rocks, down the hill, and into the nearest river. And this will happen every time it rains for the next 10,000 years. Obviously, that’s going to have a big impact on the environment.
Before matter and energy were concentrated in certain ways, and the environment had adapted to that. Then you came, extracted something from the environment, and had to move a lot of things out of the way to get to the things you wanted. Matter and energy moved from areas of high concentration to areas of low concentration, and consequently became distributed more evenly throughout the world. Then when it rained, matter and energy got even more evenly distributed throughout the world, and moved to areas of even lower concentration. All that arsenic being scattered more evenly throughout the world changed the environment, even though it’s only a byproduct of your mining the copper you wanted.
Now let’s say a lot of city people want to feel like they’re doing something to help the environment, so they’ve agreed to pay you a lot of money to mine all that copper and use it to build a solar power station. So you cut down the forest to free up the land to build the solar power station. It takes a lot of energy to mine all the minerals it takes to build the solar power station, process them, build the solar power station, maintain it, and operate it. You have to run a lot of machinery to do all of that, and you have to feed the people who work at the station as their full time occupations.
Well guess what. The forest you cut down to build your solar power station already was a solar power station. When you add up all the energy that your artificial solar power station produces and subtract all the energy it takes to run your artificial solar power station, the forest harnessed solar energy more efficiently than your artificial solar power station. The forest was a solar power station that mined all of its own minerals, built itself, and didn’t depend on any people at all to make it function.
Your solar power station is more efficient at generating electricity than the forest was, because the forest didn’t generate electricity at all. That means your artificial solar power station generates energy that’s useful to humans more efficiently than the forest did, but the gross energy it harnesses is less than what the forest harnessed. So your so-called environmentally friendly alternative energy source is still destroying the environment. But the city people who voted to let you build the solar power station are never going to know that.
