THE SONG OF THE ERAS

Cosmic time · Alien civilizations · Silence · Fossil signals

— Floriano Righetti

«We are not alone in the universe. We are only out of time.»

A visionary essay on the paradox of when: what if civilizations are not alone, but out of time?

founding thesis

The problem is not only where. It is when.

The Song of the Eras begins from a variation of the Fermi paradox: perhaps the decisive distance is not only distance in space. It is distance in time.

A galaxy may contain many voices across billions of years, but very few able to sing and listen in the same interval. The cosmos may not be empty: it may be asynchronous.

structure · seven parts

Seven cosmic movements

The book moves through silence, civilizational windows, temporal distance, technosignatures, asynchrony, stellar requiem and the listening of time.

  1. I The Great Silence Cosmic silence does not prove the absence of life. It may prove the absence of synchronization.
  2. II The Windows of Civilizations A civilization may sing for ten thousand years. A galaxy listens for billions.
  3. III The Distance of Eras Civilizations do not lose one another in space. They miss one another in time.
  4. IV The Music of the Absent The universe is not mute. It is full of notes arriving without their musician.
  5. V Civilizations Out of Sync Intelligences are not absent. They miss each other.
  6. VI The Requiem of the Stars Every star may have had a listener. Not necessarily in the same century.
  7. VII Learning to Listen to Time First contact may not be a conversation. It may be a relic.

lexicon

Key concepts
