Fermi

What is the Fermi Paradox?

• Even with the huge number of planets in the Milky Way, we haven't seen any signs of aliens

• It would take a couple of million years to colonize the whole galaxy.

• There are three different possible levels for a civilization.

• There are no aliens in the universe.

What is the first option for a Great Filter explanation of the Fermi Paradox?

• there are great filters and we have already passed through them

• There are no great filters

• The formation of Earth was not as hostile as it is for other civilizations.

Which is the best definition of Fermi Paradox?

• The contradiction between the lack of evidence for extraterrestrial intelligence and the presumed high probability of them.

• The idea that there is definitely intelligent life in the universe.

• A hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output.

What is the second possible Great Filter explanation for the Fermi Paradox?

• There are great filters and they are all ahead of us.

• Technology is the great filter that will destroy humanity.

• There are no great filters.

• Climate change is a great filter.

Another possible explanation for the Fermi Paradox is that humans are alone in the universe. Is this a "great filter" explanation?

• yes

• No

One explanation or solution for the Fermi Paradox is that our technology is not yet advanced enough to communicate with any intelligent life elsewhere in the universe.

• True

• False
