What is the fine-tuning of the universe for Life? Welcome to Alas Lewis & Barnes, a "conversation" about the universe between two cosmologists. Always sciency, sometimes funny, never boring. Geraint Lewis is a Professor of Astrophysics at the Sydney Institute for Astronomy, University of Sydney. 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 Barnes is a John Templeton Fellow at Western Sydney University. With a PhD in astronomy from 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 is the coauthor with Prof. Geraint Lewis of "A Fortunate Universe: Life in a Finely-Tuned Cosmos", published by Cambridge University Press. Music: https://www.bensound.com
If the universe was even slightly different in some of its fundamental physical properties, life could not exist – such is the claim of ‘fine tuning’ of the universe for life. The topic of fine tuning has received attention from physicists, philosophers and the popular press. In A Fortunate Universe: Life in a Finely Tuned Cosmos (Cambridge University Press, 2016), Geraint Lewis (Professor of Astrophysics, Sydney Institute of Astronomy, the University of Sydney) and Luke Barnes (John Templeton Fellow, Astronomy, University of Western Sydney) explain clearly what fine tuning is and give examples from across physics based on recent research, with many memorable analogies and pictures. They respond to many common objections to the scientific claim of fine tuning, and helpfully discuss what it might mean for physics and our concept of the world more broadly, comparing possible solutions to the issues raised by fine tuning, including a naturalistic multiverse hypothesis and theism. The book is technically precise in both the science and philosophy of fine tuning, and written in an accessible entertaining way, guaranteeing that it will be of interest to a wide audience. Check out the book’s website here, and Twitter feed here. For more, discussions between the authors relating to the book and similar topics can be found at ‘Alas Lewis & Barnes’. Zachary Ardern is a postdoctoral researcher in microbial evolution, with additional interests in the philosophy of biology and the science-religion discussion. Learn more about your ad choices.
