The goal of this course is to understand our place in the physical universe by examining three recent concepts that have revolutionized cosmic awareness. The observations that led to the proposals of Dark Matter and Dark Energy, the re- classification of Pluto to non-planet status, and the discovery of many planets orbiting other stars within life-sustaining regions called Habitable Zones radically change the human perspectives on origins and life. In each case, the roles of evidence, validation and conclusions are used to enhance students capabilities and skills needed for our modern age. Carries natural science divisional credit in CAS. Effective Fall 2018, this course fulfills a single unit in each of the following BU Hub areas: Scientific Inquiry I, Quantitative Reasoning I, Teamwork/Collaboration.
