En 1974, desde el radiotelescopio de Arecibo, Puerto Rico, la humanidad envió al espacio uno de sus mensajes más ambiciosos.

Una secuencia matemática.
Un patrón diseñado para ser entendido por otra inteligencia.

Décadas después, el mensaje sigue siendo una pieza real de la historia científica. Pero también abrió una pregunta incómoda:

¿Qué ocurre cuando una civilización intenta presentarse ante lo desconocido?

ARECIBO reconstruye el contexto técnico, humano y simbólico detrás de aquella transmisión. Desde la ingeniería del radiotelescopio hasta la lógica del mensaje binario, la obra avanza entre hechos documentados, observación científica y una hipótesis que nunca termina de cerrarse.

No es solo la historia de una señal enviada.

Es la historia de una espera.

Y de la posibilidad de que ciertos mensajes no desaparezcan cuando dejan la Tierra.
