Geraint F. Lewis is a Professor of Astrophysics at the Sydney Institute for Astronomy, University of Sydney. He undertook his undergraduate education at the University of London before gaining a Ph.D. in Astrophysics from the Institute of Astronomy, University of Cambridge. Professor Lewis is an internationally recognised astrophysicist, and has published more than two hundred papers in a diverse range of fields, including gravitational lensing, galactic cannibalism, cosmology and large-scale structure. As well as being an accomplished lecturer, he regularly engages in public outreach through public speaking, articles in the popular press, and social media. Luke A. Barnes is a postdoctoral researcher at the Sydney Institute for Astronomy, University of Sydney. His university medal from the University of Sydney helped him earn a scholarship to complete a Ph.D. at the University of Cambridge. He has published papers in the field of galaxy formation and on the fine-tuning of the Universe for life. He has been invited to speak at the 2011 and 2015 St Thomas Summer Seminars in Philosophy of Religion and Philosophical Theology, the University of California Summer School for the Philosophy of Cosmology, and numerous public lectures.
'My colleagues, Geraint and Luke, in A Fortunate Universe, take you on a tour of the Cosmos in all of its glory, and all of its mystery. You will see that humanity appears to be part of a remarkable set of circumstances involving a special time around a special planet, which orbits a special star, all within a specially constructed Universe. It is these sets of conditions that have allowed humans to ponder our place in space and time. I have no idea why we are here, but I do know the Universe is beautiful. A Fortunate Universe captures the mysterious beauty of the Cosmos in a way that all can share.' Brian Schmidt, Australian National University, Canberra, and Nobel Laureate in Physics (2011), from the Foreword Advance praise: 'Geraint Lewis and Luke Barnes provide a breathtaking tour of contemporary physics from the subatomic to the cosmological scale. Everywhere they find the Universe to be fine-tuned for complex structure. If the quark masses, or the basic forces, or the cosmological constant had been much different, the Universe would have been a sterile wasteland. It seems that the only reactions are either to embrace a multiverse or a designer. The authors have constructed a powerful case for the specialness of our Universe.' Tim Maudlin, New York University Advance praise: 'The Universe could have been of such a nature that no life at all could exist. The anthropic question asks why the constants of nature that enter various physical laws are such as to permit life to come into being. This engaging book is a well-written and detailed explanation of all the many ways these physical constants affect the possibility of life, considering atomic, nuclear and particle physics, astrophysics and cosmology. It then discusses in an open-minded way the variety of explanations one might give for this strange fine-tuning, possible solutions ranging from pure chance, existence of multiverses, or theistic explanations. The book is the most comprehensive current discussion of this intriguing range of issues. Highly recommended.' George Ellis, University of Cape Town Advance praise: 'Lewis and Barnes' book is the most up-to-date, accurate, and comprehensive explication of the evidence that the Universe is fine-tuned for life. It is also among the two most philosophically sophisticated treatments, all the while being accessible to a non-academic audience. I strongly recommend this book.'
