HOW IT WORKS
We Broadcast It Into Space
We encode your message into a radio signal and transmit it using long-distance radio frequencies designed to travel beyond Earth. From there, the signal continues its journey through space — past planets, stars, and potentially across the galaxy. Whether anyone receives it is unknown, but your message will keep traveling for years to come.
