[15 points.] The Drake equation can be used to show that Earth is the only advanced technological civilizations in the Milky Way. Discuss a plausible argument against this unreasonably pessimistic result.
Solution and grading rubric:
- p = 15/15:
Correct. Discusses in some form how a null result cannot disprove a hypothesis, the Mediocrity Principle/Copernicanism, the Scale Argument, or any sound, principled, reasonable argument against overly pessimistic results from the Drake equation. - r = 12/15:
Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. - t = 9/15:
Contains right ideas, but discussion is unclear/incomplete or contains major errors. Argues uncertain, unproven characteristics ("SWAG") of Drake equation components, or instead cites arguments against unreasonably optimisitic results. - v = 6/15:
Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. - x = 3/15:
Implementation/application of ideas, but credit given for effort rather than merit. - y = 1.5/15:
Irrelevant discussion/effectively blank. - z = 0/15:
Blank.
