BBC Sky at Night Magazine - January 2020
“Are you unhappy with the state of cosmology and think it needs to be revolutionised? If so, cosmologists Luke Barnes and Geraint Lewis have written The Cosmic Revolutionary's Handbook just for you. The inspiration will be familiar to many an astronomer or cosmologists: letters from people who think they have a new theory to explain the Universe, but who can't get the details (or the maths) right.
“The book starts with a comprehensive explanation of how theories are developed and evidenced by new observations – or how observations are explained by new theories. From a thorough consideration of Olbers’ Paradox (“Why is the sky dark?”) to observations of the expanding Universe and its composition, the focus is on the Universe’s origin and evolution.
"… the book would be a great starting point for budding astronomers or cosmologists who want to ‘debunk’ would-be revolutionaries – or answer the “but how do we know…” they’re likely to get asked.”

"In The Cosmic Revolutionary’s Handbook, Luke Barnes and Geraint Lewis (well-known and respected cosmologists) set out to describe why cosmologists believe in the Hot Big Bang (HBB) model and all the apparent complications it brings, focusing on a set of key facts that any theory wanting to overthrow the HBB model must be able to explain better. The book is extremely well organized into ten chapters. The book puts emphasis on providing observational facts that are as up-to-date and raw as possible. ...
"In addition to an excellent account of the observational foundations of the HBB model, the authors provide a remarkably accurate insight into how science really is done, without leaving out the less-pleasing parts of how human bias, mistakes and academic dishonesty are unfortunately part of the game. At the same time, the authors provide superb concrete examples of how to do good science, as well as how not to do science (in this respect, I feel that many professional scientists would benefit from reading this book!) ...
"Overall, The Cosmic Revolutionary’s Handbook is a must-read for anyone interested in better understanding why cosmologists believe all those very strange things about the Universe. Mind you, new Galileo, you will still need a degree in physics and professional research training if you want to overthrow the Big Bang model, but this book might very well be the first step towards your goal."
