Starlanguages

Starlanguages is a term used in speculative linguistics and science fiction to describe hypothetical communication systems designed to be understood across large cosmic distances. Unlike human natural languages, starlanguages are imagined to be based on signals or codes that would be intelligible to diverse intelligences, using universal or easily derivable cues rather than cultural conventions.

They typically rely on mathematical regularities, physical constants, astronomical patterns, or recurring celestial phenomena as the scaffolding for meaning. Common modalities include structured numeric or symbolic alphabets derived from primes or ratios, sequences encoded in pulsar timing, or patterns embedded in spectral lines and light curves. Some concepts imagine a shared interpretive framework established by prior contact or by alignment with the laws of physics, enabling decoding of messages without prior exposure to a specific culture.

In literature and theoretical discussions, starlanguages serve as thought experiments about the limits and possibilities of interstellar communication, the universality of computation or mathematics, and the challenges of semiotic translation among disparate intelligences.

Critics note that distance, noise, and the diversity of potential recipients make practical implementation unlikely, treating starlanguages mainly as pedagogical or narrative devices rather than feasible protocols.

Related ideas include interstellar signaling, the search for extraterrestrial intelligence (SETI), universal grammar in linguistics, and astrosemiotics.
