Cosmologists are always hearing from people who want to overthrow the ‘illogical’ and ‘unscientific’ edifice of the Big Bang theory. However, their revolution isn't quite working out.

If you have a better theory than the Big Bang, this talk will help make it battle-ready. If you don't, we'll take you on a unique tour behind the scenes of modern science, and give you a raw and comprehensive glimpse at our amazing universe.

Join Luke Barnes and Geraint Lewis as they explore how people make science’s foibles work in their favour, the hurdles that a new theory has to jump and the key facts about the universe that are non-negotiable.

About the speakers

Dr Luke A Barnes is a John Templeton Fellow at Western Sydney University. With a Ph.D. from the University of Cambridge, he has researched cosmic evolution of matter, and has published papers in the field of galaxy formation and evolution, and on the fine-tuning of the Universe for life.

Geraint F Lewis is a Professor of Astrophysics at the Sydney Institute for Astronomy, part of the University of Sydney's School of Physics. The focus of his research is cosmology and the dark side of the universe, namely the dark matter and dark energy that dominate cosmological evolution. He has published more than three hundred academic papers and is an acclaimed teacher. He also has a significant outreach profile, writing regularly for New Scientist and The Conversation, as well as regularly speaking publicly on all aspects of cosmology and astronomy.

Dr Luke Barnes and Prof Geraint Lewis are the authors of 'The Cosmic Revolutionary's Handbook (Or: How to Beat the Big Bang)' and 'A Fortunate Universe: Life in a Finely Tuned Cosmos', with Cambridge University Press. 'A Fortunate Universe' was praised by Gino Segrè in The Wall Street Journal as "charming, intelligent and exceedingly well-written, with a light hand, and a streak of humour."


The doors will open at approximately 6.30pm, with a prompt start at 7.00pm. There will be time for questions after the talk.

Latecomers will be admitted into the gallery.
