Speaking for Planet Earth: Our Message to the Cosmos

A public lecture by Dr Francisco Diego


Within the next few million years there is the very remote possibility that distant alien civilisations will receive material evidence of our presence in the Universe. This evidence consists of the battered remains of some of our spacecrafts, on their way to the nearby stars, having left our solar system forever.

Protected within their metallic structures are messages, information about us that we assume any alien civilisation would like to know. What kind of universal language was used? What was said within the very limited space constraints? In a way the messages are self-reflections about how we see ourselves within the vast cosmic arena.

This lecture explores the recent scientific, technological and intellectual achievements that made this amazing project possible. In the long term, will these spacecrafts become the only survivors of our fragile and ephemeral efforts, the only ones that will speak for planet Earth?
