The Fermi Paradox: Are We Alone in the Universe?

The video explores the Fermi Paradox, which questions why we haven't found evidence of intelligent life despite the high probability of its existence. It presents Fermi's arguments, including the vast number of stars and potential Earth-like planets. The video also discusses various theories explaining the paradox, such as the rarity of life, technological limitations, self-destruction, and communication challenges.

What is the main question posed by the Fermi Paradox?

• Why is the universe expanding?

• Why have we not found evidence of intelligent life despite high probabilities?

• What is the origin of the universe?

• How do stars form in the galaxy?

Which of the following is NOT one of Fermi's arguments?

• The universe is only a few thousand years old.

• Some stars have Earth-like planets capable of developing life.

• There are billions of stars in the galaxy.

• Interstellar travel could be possible for some civilizations.

What is one possible explanation for the Fermi Paradox?

• Humans are the only intelligent species.

• The universe is too small for other life forms.

• Intelligent life is too far away to detect.

• Aliens have already visited Earth and left.

Which theory suggests that intelligent life might destroy itself?

• The Big Bang Theory

• The Self-Destruction Hypothesis

• The Rare Earth Hypothesis

What might be a reason for intelligent alien life to avoid contact with humans?
