Event
For the second year in a row, the department of Physics and Astronomy has been awarded one of Penn's six booths at the Carnival. We will talk to the public about the size and scale of planets and how big we think planet X might be. We will explore how large amounts of matter can gravitationally lens objects behind them giving us unique insight into far away galaxies and to explore the mass that is causing these disturbances and a few more demos
