Video: Interview with Geraint Lewis 

Latest Reviews

Nature Astronomy - February 2020

"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."

'Overthrowing all of modern cosmology isn't easy, but it could happen. Maybe you will be the one to do it! If you're up for the challenge, Luke A. Barnes and Geraint F. Lewis tell you exactly what you have to accomplish. Even if you don't topple the stodgy edifice of modern science, you'll certainly learn some exciting things about the universe along the way.'

Sean Carroll, author of Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime


'If you are looking for a fun rendezvous with the universe, this is the book for you! Barnes and Lewis help you understand the basics of cosmology with simplicity and clarity - quite a feat given the complexity of our universe.'

Priyamvada Natarajan, author of Mapping the Heavens: The Radical Scientific Ideas that Reveal the Cosmos
