Beholding the Big Bang

Related to an earlier work Machine with Concrete, the motor drives a series gears designed to reduce its input speed such that it will take 13.7 billion years to turn the final gear in the train, embedded in a concrete block, once.  This is the estimated age of the universe.  (At the moment of construction.  The estimate is always changing!)
