Summary: What is reality? It is one of the oldest and most profound questions in philosophy and science, yet modern discoveries have made the answer more surprising than ever. Drawing on my recently published book, The Shortest History of Reality, this talk traces humanity’s evolving understanding of the universe, from the ideas of the ancient Greeks to Einstein, quantum physics and modern cosmology, revealing how each generation has transformed our picture of what is truly real.

Geraint F. Lewis is a professor of astrophysics at the Sydney Institute for Astronomy, part of the University of Sydney’s School of Physics. He has published more than 500 papers across cosmology, galactic archaeology, gravitational lensing and the fundamental nature of the universe, and four books of popular science, including The Cosmic Revolutionary’s Handbook and Where Did the Universe Come From? His latest book, The Shortest History of Reality, is out now.
