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 primarily concerned with?

• The creation of the universe

• The development of human technology

• The absence of evidence for alien civilizations

• The speed of light travel

According to the Kardashev scale, what is a key indicator of an advanced civilization?

• The ability to travel faster than light

• The use of planetary resources

• The harnessing of energy from entire stars

• The creation of artificial intelligence

What was the primary goal of the IRIS mission in 1983?

• To catalog bright sources of infrared light

• To detect radio signals from alien civilizations

• To map the entire sky in visible light

• To find new planets in our solar system

What was the focus of the Glimpsing Heat from Alien Technology project?

• Searching for infrared signatures of alien civilizations

• Analyzing radio waves from distant stars

• Mapping the gravitational waves in the universe

• Studying the chemical composition of planets

What is a potential reason mentioned for not finding evidence of alien civilizations?

• Aliens are hiding from us

• We are not looking for the right signs

• Aliens have not developed technology

• The universe is too young for life
