“Cataclysmic disruptions in planetary motion are a regular part of a planetarium director’s job, especially preceding such popular dates as December 21, 2012. RMSC Strasenburgh Planetarium Director Steve Fentress leads a stroll through the twilight realm of disturbances in the things we count on most: days, seasons, and years. Many world-ending options exist only in private universes, but recent supercomputer simulations show that orbits do change, and that kids who are appalled by the distances to Uranus and Neptune in their solar system models are on to something.”
