Strategies for Communication with Alien Civilizations

Eschatological articles, countermeasure articles. This guide is based on the premise that Earth does not yet have the ability to travel across galaxies, and that visiting aliens are much more advanced than us. If you want to be strong, then this guide is useless. The size of the universe is beyond our imagination. The earth is just a planet. The solar system may be very big in our eyes, but it is indeed a very inconspicuous existence in the universe. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
