Summary: Is there alien life on alien worlds? As we look out into the universe, we find more and more planets, but our search for extraterrestrial life has so far yielded nothing. In this talk, Geraint Lewis will explore our scientific understanding of life in the universe, our continuing search for the signatures of alien civilisations, and address the question of “where is everybody?”. We will find that, whilst life may be common, intelligent life and star-crossing civilisations appear vanishingly rare, and we might be alone in the universe.

Born and raised in Old South Wales and passionate about astrophysics, Geraint Lewis spends his time unravelling the dark side of the universe, the dark matter and energy that dominate the cosmos. As a Professor of Astrophysics at the Sydney Institute of Astronomy, his research focuses on cosmology, gravitational lensing and galactic cannibalism, as well as exploring why our universe appears to be just right for complexity and life, publishing more than four hundred research articles. He also undertakes a broad array of award-winning science outreach, bringing the wonders of the cosmos to broad audiences through public speaking and writing, including publishing several world-renowned books on the mysteries of the cosmos.
