Question

Quizplus · Accepted Answer

The average life span of a civilization is a key factor in determining the number of technologically advanced civilizations in the Galaxy. If civilizations have short life spans, there may be fewer currently existing ones. On the other hand, if civilizations have long life spans, there may be many existing at the same time, increasing the chances of detecting signals from them. The average life span of the civilization is important to consider because a civilization may develop advanced technology but then eventually collapse or destroy itself before having the chance to communicate with other civilizations. Therefore, civilizations that have a longer average lifespan may be more likely to have the opportunity to develop and use advanced communication technology, increasing the likelihood of detecting their existence. The other options may have some relevance, but they are not as critical in determining the number of technologically advanced civilizations in our galaxy as the average lifespan of a civilization.
