Why haven’t we found traces of extraterrestrial civilizations yet? In the observable Universe, there are more than 10 sextillion stars and billions of planets similar to Earth, yet the cosmos remains silent. We will analyze all the scientific theories that explain this paradox: from the Great Filter hypothesis to the idea of voracious aliens. We will discover why some scientists believe that finding life on Mars would be the worst news for humanity and understand what future might await our civilization.
For the creation of this video, I mainly relied on:
The article by Tim Urban “The Fermi Paradox” (Wait But Why - waitbutwhy.com...)
The books by astrophysicist and cosmologist Max Tegmark: "Life 3.0: Being Human in the Age of Artificial Intelligence" and "Our Mathematical Universe: My Quest for the Ultimate Nature of Reality"
The book by theoretical physicist Jim Al-Khalili: Aliens: The World's Leading Scientists on the Search for Extraterrestrial Life
The book by philosopher Nick Bostrom: Superintelligence: Paths, Dangers, Strategies
The video by the Rational Animations channel about voracious aliens ( • Humanity was born way ... )
