When we look at the starry sky we cannot help wonder whether we are alone in the universe or whether other sentient beings exist, and if so how far away they are. Maybe the light reflected off our planet and old radio transmissions have travelled through the enormous distances of space and reached intelligent beings, who may also be wondering whether there is life here. Presently we do not have the technology to travel far outside of the solar system and check this out for ourselves, but since time immemorial philosophers have been debating whether we are the only intelligent species in the universe, while scientists have devised experiments to detect signs of life outside of Earth. In this keynote address, we’ll hear from one of the topmost Australian researchers in the field of astrobiology what we have learned so far, and will be treated to a thought-provoking travel through time and space to answer the ultimate question: are we alone?
Dr Charles (Charley) Lineweaver is the convener of the Planetary Science Institute (PSI) of the Australian National University (ANU), where he holds a joint Associate Professorship in the Research School of Astronomy and Astrophysics, and the Research School of Earth Sciences. He obtained his PhD from the University of California at Berkeley, where he was a member of the COBE satellite team that discovered temperature fluctuations in the cosmic microwave background. His current research ranges from cosmology, to exoplanetology, astrobiology and evolutionary biology.
