The Great Silence

November 30, 2018 by David Wångstedt in Video

Description

For the past half-century, humanity has been listening for alien radio transmissions but so far we appear to be the only ones broadcasting into the void. Astrobiologists now seek to narrow down the search by looking for other technological and biological signatures. In this video, I explore some of the methods by which they hope to do so and why the great silence of the universe is such a mystery.
