Interstellar trade refers to the exchange of goods, services, and resources between different planets or star systems. This concept often appears in science fiction, where advanced civilizations engage in commerce across vast distances in space. The trade can involve various items, such as minerals, technology, or even cultural artifacts, and is facilitated by advanced spacecraft capable of traveling between stars. In a realistic scenario, interstellar trade would require significant advancements in technology, including faster-than-light travel and efficient communication systems. It would also involve complex economic systems and regulations to manage trade agreements, tariffs, and the protection of resources on different planets, similar to how international trade operates on Earth.
