🕳️ Tiny World

How far down does it go?

Fall from you, one metre tall, all the way to the bottom of everything. Powers of ten, straight down.

Knock on the table. Feels pretty solid.

Knock on your own arm. Same story.

Here’s the thing: almost none of it is.

The puzzle

So how far down does it actually go?

You know how you can zoom into a mind map, and every dot opens into a whole new map of its own? Matter is like that, except it just keeps going. Start at you, one metre tall, and fall straight down through everything you’re made of.

you 1 m the floor · <10⁻¹⁵ m

Guess first: how many zooms from you down to the smallest thing there is? … About a billion billion: a 1 with eighteen zeros after it.

Your turn. Drag the stage, scroll on it, or pull the slider up the right-hand rail to fall deeper. The big number on the left counts how small you’ve got. Tap a numbered dot to jump straight to a level.

You’re about one metre of person.100 m

The smallest thing down there is a billion-billion times smaller.< 10−18 m

Eighteen zooms, straight down. Ready?

about 1 metre

This is you: about a metre of person. Everything below this line is what you’re made of. Take a breath. We’re going all the way down.

An atom is almost entirely empty.10−10 m

The bit that’s actually stuff? A marble in an empty stadium.10−14 m

Pull out a proton. Bet it’s solid. It isn’t.10−15 m

Go deeper and it stops being tiny balls at all.

The quarks may have no size. None.< 10−18 m

Just ripples in fields that fill all of space.

Solid was never the word. Mostly nothing, held in shape.

The fall, in order

Everything you just dropped through

Eight steps, and each one is thousands of times smaller than the last. That gap between the numbers is the part worth sitting with.

    You started as a solid, obvious person.

    Eight zooms later, nothing solid was left.

    The table, your hand, the chair: all doing the same thing.

    One more thing

    Here’s what gets me. The chair you’re sitting on is a marble in an empty stadium, and under that, maybe not even things, just ripples that never stop. So is your hand. Mostly nothing, held in shape by fields.

    Pass it on. Next time someone knocks a table and calls it “solid”, you can tell them what’s actually down there: a billion-billion zooms of almost-nothing, humming in fields that fill all of space.

    Three rooms nearby go further into exactly this: what an electron really is, why everything is fields, and what’s inside a proton. Same fall, slowed right down, one strange idea at a time.

    You fell about a billion-billion times. Scroll back up to climb out.
