Modern Cosmology

You are the world’s greatest surveyor and possess an extraordinarily precise set of tools for measuring angles and distances. Bill Gates calls you up and asks you to determine whether the Earth’s surface is flat or curved. Unfortunately, you live in Seattle so it is always cloudy and you cannot see the Sun or any other object in the sky. Describe one way to carry out Bill’s assignment, without leaving the Seattle area?
