IDENTICAL CHANGES 



It is evident that every particle of the liquid in 

 the cask is affected by the movement, and the 

 bodies E and F floating in the liquid are also af- 

 fected by it. 



Yet it seems almost impossible to determine in 

 what direction the particles moved that changed 

 position, or how the position of the bodies E and F 

 was altered, relative to one another. 



Then if we can scarcely calculate the movement 

 of particles in a very limited vessel, knowing the 

 point where force enters, and also the point where 

 force leaves the vessel, how can we determine the 

 direction of universal movement ? 



For our Universe has no visible upper tube 

 where force enters, and no lower tube where it is 

 discharged, and where are the staves that may 

 constitute the bounds of the Universe? 



But let it be otherwise and let the visible stars 

 and our solar system constitute the Universe, and 

 let the Milky Way indicate the direction in which 

 universal force moves. (Hypothesis.) Then that 

 force must either move in a circle, or have an inlet 

 and an outlet. 



But force moving in a circle is not force at all, 

 to any sane reasoning, for it would balance itself. 



Then the Milky Way must have two ends, one 

 where force enters, and one end where it is dis- 

 charged. (Hypothesis.) 



Then how are these ends situated relative to one 

 another, and whence comes force to the Milky Way 

 and whither does it go when it leaves? There-
