For about a decade, Joe Davis has been trying to send a message into space. This message is not intended for potential intelligent alien listeners, though. He’s already sent two signals into the void for them. He hopes that this communiqué will reach humans. On Earth. Ideally around 1935.
The dispatch, which Davis calls Swansong, is at its simplest a one-hour Morse code transmission listing numerous pandemics, natural disasters, genocides, and other tragedies that humans failed to mitigate or prevent between 1935 and 2011.
