A single message from another world would settle ancient questions of humanity's place in the Universe and could open a new era of interplanetary dialogue. What are our chances of ever starting this conversation, or spreading life beyond Earth? I will review these questions from the standpoint of mid-2016,  taking into account the astronomical harvest of other planets, proposals for interstellar exploration, and ideas for how we might communicate between species across deep space.


Christopher Matzner is a professor of theoretical astrophysics at the University of Toronto. His work concerns the birth and death of stars, accretion onto black holes, and the role of stars in the lives of galaxies.
