1. Cosmo Sociology should be a research field<br>2. we should never make contact (Im with the Dark Forest theory here)<br>3. read Liu Cixin‘s Trisolaris Trilogy (a master piece of science fiction but actually textbooks about cosmo sociology)<br>4. Physically finding civilizations seem almost impossible for me because you can’t just search in space, you would also have to „search“ in time. When a civilization‘s timespan is ~10000 yrs, what are the odds that we are temporally overlapping with any of them? And if we are overlapping and would want to go there, the route would take more time than the civilizations life time (except, they are living next to a super massive object which cancels out the time dilation of our super-dooper fast spaceship, does this make sense?)
