Communication between different interstellar civilizations

Suppose there is a civilization on a distant planet. Its level of civilization is close to Earth, but it uses a very different method of communication from human civilization. If one day, a spaceship from the human civilization arrived on this planet. Then, what was the fastest and most effective way for humans to communicate with this alien civilization?
Mathematics was a set of logical systems created by humans to understand the world. However, alien civilizations might not necessarily use the same logical system as human mathematics.

Answer 1

Communication between different interstellar civilizations was a relatively broad and complicated topic.
1. Technology exchange: Due to the huge difference in technology between different interstellar civilizations, technology exchange was one of the important ways to establish contact between interstellar civilizations. This communication could be done through radio waves, laser communication, virtual reality, and other methods. At the same time, they could also borrow the technology of other civilizations to create their own advanced technology.
2. Cultural exchange: The cultural exchange between different interstellar civilizations is also very important. They could communicate through written, verbal, artistic, and other means. For example, some interstellar civilizations might display their culture, beliefs, traditions, and so on to other civilizations.
Political communication: Political communication between different interstellar civilizations is also very important. It could be done through diplomatic means, trade, investment, and other means. For example, some interstellar civilizations might establish diplomatic relations with other civilizations for trade and investment.
4. Emotional communication: Emotional communication between different interstellar civilizations is also very important. It could be done through music, poetry, dance, and other methods. For example, some interstellar civilizations might display their music, poetry, dance, and other artistic forms to other civilizations.
Communication between different interstellar civilizations needed to take into account various factors, including technology, culture, politics, emotions, and so on. Only through communication could different civilizations understand each other, respect each other, and build a relationship of mutual trust to promote the development and progress of interstellar civilizations.
