Six big questions about the universe and yourself. Plus a game that shrinks you down to an electron and grows you up to a galaxy.
The Earth is round. Light takes time to arrive. We are made of star stuff. Most of the universe is something nobody can identify. Ten claims, and for each one the actual method somebody used to find out — most of which you can repeat from the ground with a stick, a shadow and some arithmetic. This is the planet underneath Astrophysics, Chemistry, Physics and Geometry, because all four run on the same question.
The one to carry: "how would anyone know that?" It converts a fact you were handed into something you can check. And the harder one from mission seven — before any test, be able to finish the sentence "if I am wrong, I will see ___". If you cannot, you are not testing anything yet.
I built this planet because I'm asking these questions too. I'm a kid on this planet just like you are. The grown-ups don't have all the answers either — some of these questions are the biggest open questions in all of science. Pick a door. Sit with the question. There's no wrong answer when nobody knows the right one.
Click "smaller" to shrink down to an electron. Click "bigger" to grow up to the whole universe. There are 8 stops along the way.
Each branch is its own planet inside The Field. Each one has its own questions, its own activities, and a small curriculum to walk through. They all connect to each other — just like the universe does.
Each lesson has one question to think about, one thing to look at, and one thing to try. Take your time. Skip around. Come back to them.
PLANET · THE FIELD
This is the planet where Nathan goes to ask the questions nobody has finished answering yet. The ones about how the universe really works — and how you fit inside it.
Click any door to step inside. Each one has a question, a wonder-fact, and something to sit with.
Hook: Light is both a wave AND a particle, at the same time. Scientists fought about which one for 200 years before realizing the answer was both.
Hook: You breathe out CO&sub2;. Trees breathe it in and turn it into the oxygen you breathe back. Every breath is a trade with a tree.
Hook: Inside an atom there are quarks, electrons, and a whole lot of empty space. You're 99.9999999% empty space. Nobody talks about this.
Hook: Gravity works the same way on Earth as it does in galaxies a billion miles away. Nobody knows why the universe is lawful instead of chaos.
Hook: Time moves slower if you're moving fast or near something heavy. This is real and proven. The universe doesn't actually have one big "now."
Hook: If an atom were the size of a football stadium, the part that's NOT empty would be a single grain of rice in the middle. You're mostly nothing. So is everything.
Light comes out of the sun, hits your eyes, and shows you the world. Easy, right? Not even close.
Light is both a wave and a particle. When scientists set up experiments to test if light was a wave, light acted like a wave. When they set up experiments to test if light was a particle, light acted like a particle. Same light. Different experiments. Different answer.
For 200 years, physicists fought about which one was right. Then in the 1920s, they realized the question was wrong. Light isn't ONE thing pretending to be the other. Light is its own thing, and our words for "wave" and "particle" don't fully fit it.
Everything in the universe is like this at small enough scales. Electrons. Protons. The stuff you're made of. Reality at the smallest level doesn't behave the way our words describe.
Every breath you take, you pull in oxygen and breathe out carbon dioxide. Every "breath" a tree takes — through tiny holes in its leaves — it does the opposite. Trees pull in carbon dioxide and breathe out oxygen.
The oxygen in your lungs came from a tree somewhere on Earth. The carbon dioxide that tree just used? Came from someone's lungs. Maybe yours.
You and the trees are in a constant trade. Without trees, you'd run out of oxygen. Without you and other animals, trees would run out of carbon dioxide. Neither of you can survive alone.
This is true for every animal and every plant on Earth. The world isn't separate things bumping into each other. The world is a giant cooperation.
Atoms are tiny. About a million of them lined up would be the width of a hair. But here's the part nobody mentions in school:
Atoms are mostly empty space. An atom has a tiny nucleus in the middle (with protons and neutrons), and tiny electrons spinning way out at the edges. Between the nucleus and the electrons? Almost nothing.
If an atom were the size of a football stadium, the nucleus would be a single grain of rice in the middle of the field, and the electrons would be tiny dust specks at the seats. The rest is empty.
Inside the nucleus, protons and neutrons are made of even smaller things called quarks. Quarks come in flavors with funny names (up, down, strange, charm, top, bottom). Below quarks? Nobody knows for sure. The smaller you go, the stranger reality gets.
You are made of atoms. Atoms are mostly empty space. You are mostly empty space. So is the chair you're sitting on, the floor under it, and the planet under that.
Drop a ball. It falls. Drop another ball. It falls the same way. Drop a ball on the moon. It falls slower (because gravity is weaker), but it falls. The whole universe follows the same rules.
Why? Why isn't the universe a chaotic mess where things fall up sometimes and sideways other times? Why are gravity, electricity, and magnetism the same in galaxies billions of miles away as they are on Earth?
Nobody knows. Seriously. This is one of the biggest unanswered questions in science. Some scientists think there might be other universes out there with different laws — "multiverses." Some think the laws are baked into the fabric of reality itself. Some think we just don't understand the deeper rule that produces all the laws we see.
What we DO know: the universe is a place where you can predict what's going to happen if you understand the rules. That's not nothing. A universe without laws would be a universe nothing could grow in. No trees. No people. No questions.
Time feels obvious. The clock ticks. Yesterday happened, tomorrow will happen, you're stuck in the middle. Right? Not exactly.
Albert Einstein figured out something weird about 100 years ago, and we've been confirming it ever since: time goes slower when you're moving fast, or when you're near something really heavy (like a planet). This isn't a trick or a feeling. It's measurably true. The clocks on GPS satellites run slightly faster than clocks on the ground because they're farther from Earth's gravity.
That means there isn't ONE "now" for the whole universe. Your "now" and a galaxy's "now" might not match up. The universe doesn't have a clock everyone shares.
Some physicists today think time might not even be a real thing — that it's something our brains invent to make sense of changes. Other physicists strongly disagree. This is a live argument among the smartest people alive.
You learned in Door 03 that atoms are mostly empty space. Here's the bigger version:
The universe is also mostly empty. Stars are tiny dots in a vast dark. Galaxies are tiny dots in even vaster dark. When astronomers look at the universe, the bright stuff — stars, planets, gas clouds — is only about 5% of what's there.
The other 95% is "dark matter" and "dark energy." We can't see it. We can only feel its gravity. Most of the universe is invisible to us.
Inside YOU, atoms are mostly empty. OUTSIDE you, the universe is mostly empty. You are a small amount of "something" surrounded by enormous amounts of "we don't know yet." That's not scary. That's just how it is.
You're at "person" right now (stop 5). Shrink down to see what you're made of, or grow up to see what you live inside.
You. Made of about 30 trillion cells. Made of stuff that came from stars that exploded billions of years ago.

Question: How big is the universe?
Look at: The sky tonight. Find one star you can name (or just one you like).
Try: Use the scale-of-size game above. Click "Smaller" all the way to electron, then "Bigger" all the way to galaxy. Sit with that.
Question: If you cut something in half, then in half again, then again, then again, when does it stop?
Look at: Your hand. Notice that you are mostly empty space (atoms are 99% empty).
Try: Open the Chemistry branch. Walk through one wonder door.
Question: Why does dropping a ball look the same on Earth as it does on the moon (just slower)?
Look at: Anything that's not moving. Why isn't it moving? Something is balancing it.
Try: Drop a ball. Drop a piece of paper. Drop a balled-up piece of paper. All three fall differently. Why?
Question: A snail's shell, a sunflower, a hurricane, a galaxy — they all spiral. Is that an accident?
Look at: A pinecone. Or a sunflower. Count the spirals going one way, then the other way. The numbers are special.
Try: Open the Geometry branch. Find Fibonacci.
Question: Where did the carbon, calcium, and iron in your body come from?
Look at: A photo of a galaxy or a star nursery (search "Hubble Space Telescope photos"). The colors are real.
Try: Open the Astrophysics branch. Walk through how stars die.
Question: The chemistry in your body uses energy made by physics that traces back to the Big Bang. Where do you draw the line between you and the universe?
Look at: A tree. Then look at your hand. You're both doing the same chemistry.
Try: Visit Symbiosis — the biology version of this same idea.
14 days on the big questions — and on how anybody checked, which is the interesting part. Daily Beacon below.
This planet is one stop on a single curriculum, not a standalone topic. The same subject is taught at every level of C.U.L.T. — a cadet who starts at Sparks never starts over.
Every level is open to everybody. Nobody is asked their age, and nobody is tracked. A grown adult who never got taught this is welcome to start at the bottom rung, and a twelve-year-old who is ready is welcome to climb.
