This flash module was built around a modified version of the Drake Formula. The module attempts to guide the users thinking by analyzing the question, "How many technological civilizations are there in the Visible Universe?" The analysis proceeds by breaking this big question into a series of sub-questions. Some of these sub-questions can now be answered with some certainty while others cannot be answered at all at the present time. The intent of the module is to help users develop a more informed opinion about life in the Universe by guiding the user through this thought process with explaination and feedback as they use the calculator. It attempts to clarify the significance of the extremely large numbers the user manipulates.
