Theory of Interstellar Communication

A framework for exchanging information across interstellar distances—whether by laser, radio, or (if possible) FTL. Theory of Interstellar Communication asks: How could we talk to other stars? What would messages cost in time and energy? How would dialogue work when each exchange takes decades or centuries? The theory explores the practical and philosophical dimensions of talking across the abyss.

Theory of Interstellar Communication "A message to Alpha Centauri takes four years. A reply takes four more. Interstellar Communication theory asks: what kind of conversation can you have with eight-year gaps? Is it dialogue, or just two monologues separated by time? The theory explores the strange dynamics of talking when you'll never hear a reply from the same person."
