Episode description
Presented by James Benford on 13th March 2015.
Messaging to Extra Terrestrial Intelligence (METI) is an issue dividing those who want to announce our presence to the cosmos by broadcasting to the nearer stars and those who advocate international consultations on the societal risk of such transmissions. METI is the opposite of searching (SETI). METI transmissions to date are faint and very unlikely to be detected. If we do send messages, who should speak for us and what should they say? Should individuals and groups capable of announcing Earth civilization to the galaxy talk it over first? Recent development for starship probes to visit the stars will be briefly discussed
