Everything That Glows
Why the world that glows, remembers, lives, falls, holds, reflects, works, and counts is, underneath, made of information.

Everything That Glows is a book about the deepest idea in modern physics: that information is physical.
That to know a thing, to remember it, or to forget it is never free; that each costs something real and measurable; and that this single fact runs like a thread through heat and light, life and gravity, number and mind. It is the story of how a question about a cooling cup of coffee turned, over two centuries, into a question about everything.
It is written for the curious, not the credentialed. There is no prerequisite but attention. And it is here in full, free to read, because understanding should not sit behind a gate.
Questions you’ll get to live with
You don’t need the answers to begin — only the pull of the questions.
- Why does forgetting a single bit of information release a tiny, unavoidable trace of heat?
- What does a cup of coffee cooling on your desk have in common with a black hole?
- Is mathematics something we discover, or something we invent — and could we ever run out of it?
- Why does time run one way, when the laws underneath barely notice a direction?
- What is a “particle,” really, once you stop picturing a tiny ball?
- If the world is, underneath, made of information — whose is it, and where is it kept?

About
I am not a physicist. I am someone who could never stop asking how the world works, and who found out, slowly, that the asking is open to anyone. I wrote this book to share that, and to argue that the deepest ideas in science belong to everyone willing to look.
— Karl Meves
Questions
Is the book really free?
Yes. The entire book is free to read online, with no paywall and no sign-up.
Can I share it?
Please do. Send the link to anyone who might be curious; sharing it is the whole point of keeping it free. The text stays the author’s own, so please point people to the book here rather than reposting it elsewhere, but the link is yours to spread as widely as you like.

Can I read it offline?
Yes. The site is a Progressive Web App: once loaded it works offline, and you can install it to your phone or desktop home screen.
What is the book about?
In twelve chapters it argues that the world is, underneath, made of information — tracing one idea through heat, memory, life, gravity, matter, measurement, number, and more.
How long is it?
Twelve chapters, around nine hours of reading in total, though it is built to be read in pieces. The book holds your place, so you can read a section at a sitting and come back whenever you like.
Who wrote it?
Karl Meves, who is not a physicist but someone who could never stop asking how the world works. The short version is in the foreword; the longer answer is the book.
