The "Great Filter" is a concept in the field of astrobiology and the search for extraterrestrial life. It suggests that there is a stage in the evolution of life that is extremely difficult to surpass, which could explain why we have not yet found evidence of intelligent civilizations in the universe. This filter could occur at various points, such as the emergence of life, the development of complex organisms, or the ability to create advanced technology. The idea raises questions about humanity's future and whether we have already passed the Great Filter or if it lies ahead. If it is behind us, it may indicate that intelligent life is rare. Conversely, if it is still to come, it could mean that civilizations tend to self-destruct before achieving interstellar communication or travel, posing a risk to our own survival as we advance technologically.
