About this listen
In 1972, humanity sent its first interstellar introduction.
Bolted to the side of Pioneer 10 and later Pioneer 11, a small gold-anodized aluminum plaque carried a bold message into deep space. Designed by Carl Sagan and his team, it featured a naked human couple, a map of our solar system, and pulsar coordinates pinpointing Earth’s location in the galaxy.
But was this scientific brilliance… or cosmic recklessness?
In this episode, we decode the symbols of the Pioneer Plaque, uncover the controversy it sparked, and explore the deeper question it raises:
Should humanity reveal itself to the universe — or stay silent in the dark?
