Terms of Sale
Last updated: October 23, 2026
These terms apply when you use this website or buy an e-book from Slow Sky Books. By buying, you agree to them. “We” means Slow Sky Books (slowskybooks.com), the publisher of this book and of the Slow Sky channel on YouTube.
Who sells the book
Your order is sold and processed by Gumroad, which acts as the merchant of record: it takes the payment, charges any sales tax or VAT, and delivers your download. Gumroad’s own terms also apply to the payment.
What you buy
Nobody Said Impossible is a digital book: a PDF file that you download after payment. It is not a printed book and nothing is shipped. Prices are in U.S. dollars and are shown before you pay.
Your license
- The book is for your personal, non-commercial use. You may read it on your own devices and print copies for yourself and your household.
- Please don’t share the file, post it online, resell it, or copy large parts of it. Short quotes with credit are fine.
- The text, layout and our own pictures are protected by copyright. Photographs by others are used under their licenses, listed in “Picture Credits” at the back of the book.
About the content
We work hard to get the science right, and every chapter says plainly what is known, what is still open, and what is a dream. The “Let’s Imagine” pages are imagination, clearly marked as such; they are not predictions. Science keeps learning, so some answers will change. The book is general information, not professional advice.
The book suggests things to look for in the night sky. Never look at the Sun with your eyes, binoculars or a telescope unless you use a proper solar filter, and watch your step outdoors in the dark.
Refunds
See our Refund Policy.
Limits of our responsibility
The book and this website are provided “as is”. To the fullest extent the law allows, we are not liable for indirect or consequential losses, and our total liability for any claim about a purchase is limited to the amount you paid for it. Nothing in these terms limits rights you have under the consumer laws of the place where you live.
Changes
We may update these terms. The version on this page on the day you buy applies to your purchase.
