   In any situation, the masses involved create a potential, and this   
   potential (or its gradient, the field) determines the motions.  In a   
   stationary (which is not the same as static) system, the masses will   
   create a field which causes motions such that the masses will create the   
   same field.  Such a configuration is a singular isothermal sphere, which   
   is a good approximation to globular clusters.   
      
   As to why there are no collisions, even in a globular cluster stars are   
   orders of magnitudes smaller than the distances between them.   
   Nevertheless, sometimes (near) collisions occur and can lead to one star   
   being ejected to the system.   
      
   Nothing mysterious here, all explained well by Newton's law of gravity,   
   nothing else needed.
