   C, is the speed of light which is the maximum speed   
   possible. One interesting experiment with light involves   
   shooting individual particles of it to a photo detector,   
   through a double slit. When the particles pass through   
   a double slit, they change from particles to waves.  By   
   shooting these laser particles along a pathway long   
   enough, say 2 light seconds. We could try all sorts of   
   new things.  For example, what would happen if we   
   interrupted the light particles after they already started to   
   travel along the pathway. And could we change light back   
   into particles after turning it into a wave?
