The Fermi Paradox and Our Search for Alien Life

The video explores the Fermi Paradox, questioning why we haven't found evidence of alien civilizations despite the vastness of the universe. It discusses the Kardashev Scale, which measures a civilization's energy use, and how advanced civilizations might produce detectable waste heat. Infrared surveys, like those conducted by IRIS and NASA's WISE Telescope, have searched for such signs but found none attributable to alien technology. The search continues with new missions planned, but the question of where the aliens are remains unanswered.

What is the Fermi paradox and why is it significant in the search for extraterrestrial life?

What methods have scientists used to search for signs of advanced civilizations?

According to Nikolai Kardashev, what happens when a civilization develops sufficiently?

What were the findings of the infrared astronomical satellite IRIS regarding advanced civilizations?

What are some possible reasons why we have not yet detected extraterrestrial civilizations?
