Everything around you — rocks, sunlight, and even your own thoughts — is made of something. Scientists call it substance. And all substance shares five special properties. Think of them like superpowers that everything has.

1. Space — How Much Room Things Take Up

Everything takes up space. A rock takes up a tiny, squished amount of space. Light spreads out over a huge amount of space. And your thoughts? They take up space too, but it’s a different kind — it’s mental space inside your mind.

Here’s something cool: there’s no such thing as truly empty space. Even a room with no furniture still has light and air in it. Space always has something in it.

2. Time — How Long Things Last

Time is how long something sticks around. A mountain lasts millions of years — it has a lot of time. A flash of light zips by super fast — it has much less time. Your thoughts? Sometimes a minute feels like forever (like waiting for summer vacation), and sometimes an hour feels like five minutes (like playing video games). That’s mental time!

3. Inertia — How Stubborn Things Are

Inertia means things don’t like to change. A bowling ball sitting still doesn’t want to move. Once you push it, it doesn’t want to stop. That stubbornness is inertia.

A spinning top is a great example. It stays upright because it’s spinning — it’s “centered.” Rocks and heavy things have lots of inertia. Light has very little. Thoughts can be stubborn too (ever tried to stop thinking about something?) or they can flow freely.

4. Motion — How Much Things Move Around

Motion is how much something naturally moves. Rocks and mountains barely move at all. Light zooms at 186,000 miles every second — that’s insanely fast. Thoughts can jump from one idea to another almost instantly.

Here’s the interesting part: inertia actually keeps things moving the same way. It’s what keeps light going at the same speed all the time.

5. Gravity — The Balancing Act of the Universe

Gravity is like inertia, but for a whole group of things working together. Think about the solar system: the sun, Earth, Mars, and all the planets are moving in a giant, balanced dance. Gravity keeps that dance going. If something bumps into the dance, gravity tries to fix it and bring everything back to balance.

Why Does This Matter?

Most science books treat space and time as if they exist on their own, floating out there in the universe. But this book says: no substance = no space, no time, no inertia, no motion, no gravity. They only exist because things exist.

Science also usually thinks of inertia as just “stubbornness.” But here, inertia is seen as something deeper — it’s what gives everything its natural rhythm of movement, and gravity does the same thing for whole systems of objects like solar systems.

It’s a new way of looking at the universe — from the inside out.
