The G\"odel Universe: A Practical Travel Guide
  We study the G\"odel universe through worldlines associated with motion at constant speed and constant acceleration orthogonal to the instantaneous velocity (WSAs). We show that these worldlines can be used to access every region -- both spatial and temporal -- of the space-time. We capture the insights they accord in a series of sketches, which extend significantly the Hawking and Ellis picture of the G\"odel universe.
