Our second confirmed keynote speaker will be Stephen Webb, Ph.D.

Following a PhD in theoretical physics, and then positions at a number of UK universities, Dr. Webb now works at the University of Portsmouth on the south coast of England. He is the author of 10 books, including an undergraduate textbook on the cosmic distance ladder, a study of the new generation of astronomical observatories, and the best-selling “Where is Everybody”, a wide-ranging look at approaches to Fermi’s famous question. He is an active member of the UK SETI Research Network, and engages enthusiastically in various outreach activities – his TED Talk “Where are all the aliens?” has had over 6 million views. Stephen serves on the editorial board of Springer’s “Science and Fiction” book series, and he is always interested in reading proposals that explore and exploit the interface between accepted science and its fictional counterpart.

His talk is tentatively titled: “Silence is Golden: SETI and the Fermi Paradox”
