2. This is question you have to think about – there is no textbook or google answer available to you: Consider our galaxy to be a very thin circular disk of stars of radius approximately 50,000 light years. If there are currently 2500 civilizations in our galaxy capable of communication, what is the approximate separation of these civilizations (in units of light years) if they are uniformly (e.g. equally spaced) distributed within this circular disk of stars? (it helps to visualize this problem by drawing a circle and putting some uniformly space dots in that circle and then thinking about the problem that is being asked).
