Fermi Paradox and Extraterrestrial Life Quiz

What question did Enrico Fermi, a Nobel Prize-winning physicist, ask that originated the paradox explored in the video?

• Is there life on other planets?

• Where is everybody?

• How can we travel to other galaxies?

• Are aliens hostile?

According to the video, what is one implication of the vastness of the observable universe for the question of extraterrestrial life?

• Life can only exist on a limited number of planets.

• With countless galaxies and planets, life might thrive in many places.

• The distance between galaxies makes detecting life impossible.

• The universe is expanding too quickly for life to develop.

Which hypothesis suggests that there is an extremely difficult obstacle for life forms to overcome, preventing them from evolving into highly intelligent species like us?

• The zoo hypothesis

• The self-destruction hypothesis

• The Great Filter

• Technological barriers

According to the video, how might certain advanced civilizations inadvertently cause their own destruction?

• By depleting their planet's natural resources.

• By engaging in wars with other space civilizations

• By developing cutting-edge technologies that become catalysts for their downfall.

• By ignoring climate change on their planets.

Which hypothesis proposes that traveling between stars is so tricky that even super-intelligent aliens may not have been able to overcome this challenge?

• The Great Filter hypothesis

• The self-destruction hypothesis

• Technological barriers

• The zoo hypothesis

What does the zoo hypothesis, presented in the video, consist of?

• That aliens are hidden in space zoos.

• That advanced civilizations might be deliberately avoiding contact with us to observe us or to avoid interfering with our development.

• That Earth is an isolated planet with no extraterrestrial life.

• That aliens communicate only through radio signals.

According to the video, what are some examples of factors that could lead advanced societies to self-destruct before establishing communication with other planets?

• Asteroid impacts and solar flares.

• War and environmental degradation.

• Lack of natural resources and overpopulation.

• Incurable diseases and social isolation.

Why does the video suggest that our search for aliens might have been limited so far?

• Because we don't have enough technology to detect alien signals.

• Because aliens are too far away to be detected.

• Because we have primarily focused on the search for radio signals and exoplanets, without exploring other possibilities.

• Because the universe is too young to have developed advanced life.

According to a Pentagon report mentioned in the video, approximately how many UFO encounters occurred between 2004 and 2021?

• 44

• 144

• 244

• 344

What was the conclusion about most of the UFO encounters mentioned in the Pentagon report?

• Most were identified as extraterrestrial phenomena.

• Some were identified as secret military aircraft.

• Most could not be identified, and only one was possibly identified as a large deflating balloon.

• All were considered hoaxes or optical illusions.
