In 1950, the physicist and Nobel laureate Enrico Fermi famously asked his colleagues: “Where are they?”

Given the vastness of the space and how our civilization had evolved, theoretically, there should be some other civlization in the universe that we could somehow see. We have pretty powerful tools and if other intelligent life forms would exist, they would have probably evolved in a similar way we did. Thus, they would also have tools to give or intercept signals.

Yet, where are all these aliens? Why haven’t they contacted us? Are we the most intelligent life form in the entire universe?

Well, the answer of the above question might be yes!

The Great Filter is a terrifying concept. It states that civilizations must overcome certain challenges in order for them to survive. These challenges might vary based on where the life took form, however, every civilization gets to a point, a final challenge, which is the most difficult to pass.

Passing it means continous prosperity and evolution for that civilzation, failing it results in complete extinction.
