Exploring Extraterrestrial Life and the Fermi Paradox

What is the estimated time humanity might have to wait to receive a message from an extraterrestrial civilization?

• 1,000,000 years

• 400,000 years

• 200,000 years

• 100,000 years

What is one reason suggested for why advanced civilizations might not reach us?

• They are too far away

• They are hiding from us

• They might stagnate or collapse

• They are not interested in us

What is the Fermi Paradox primarily concerned with?

• The expansion of the universe

• The speed of light

• The rarity of intelligent life

• The existence of black holes

According to Song and Gao, what is a challenge in studying extraterrestrial civilizations?

• Technological limitations

• Too many variables

• Only one data point available

• Lack of funding

What does the Drake Equation attempt to estimate?

• The age of the universe

• The number of communicating civilizations

• The number of stars in the universe

• The number of black holes

In the optimistic scenario, how many CETIs might exist in the Milky Way?

• 42,000

• 1,000

• 111

• 36

What is the Great Filter hypothesis about?

• The filtering of radio signals

• The self-limiting nature of civilizations

• The filtering of cosmic dust

• The filtering of light through space

What might cause civilizations to collapse according to Wong and Bartlett?

• Natural disasters

• Burnout or prioritizing homeostasis

• Alien invasions

• Lack of resources

What is a potential outcome for civilizations that prioritize homeostasis?

• They become more detectable

• They expand rapidly

• They become difficult to detect

• They develop new technologies

What might be the first indication of extraterrestrial life we detect?

• A hostile invasion

• A new star

• A sign of intelligent but unwise life

• A peaceful message
