Tähekaupa

Tähekaupa is a term used in Estonian-language discourse to describe the hypothetical practice of interstellar commerce. The word combines tähe, meaning star, with kaup, meaning trade or goods, forming a compound that denotes trade across stellar distances. In common use, tähekaupa refers to the exchange of goods, services, and information between distant star systems, typically imagined as enabled by advanced transport and communication technologies such as faster-than-light travel, wormholes, or stargates.

As a concept, tähekaupa functions primarily as a thought experiment for space economics. It is used to explore questions of cost and pricing across space, currency and accounting in multi-system economies, risk management under long transit times, and the political or legal frameworks that would govern cross-border (or cross-system) trade. Typical topics include logistics networks, standardization of measurement and quality, resource allocation, and sovereignty over interstellar trade routes.

In practice, tähekaupa appears mainly in science fiction criticism, futurist discussions, and speculative economics. It is not an established field with a single agreed-upon definition, and its meaning can vary significantly between authors and studies. Critics and commentators often use the term to illuminate the challenges and opportunities that would accompany any real or imagined system of interstellar exchange.
