84 TWO NEW WORLDS 



embodiments of some human will. Why should 

 not other objects, equally " substantial," be the 

 embodiments of some will different from our own ? 

 Our next step in the exploration of the universe 

 must be to get at its inner soul and meaning. So 

 far we have only examined, so to speak, its size and 

 shape, its clothing, its gait. We must now get to 

 a bowing acquaintance, and by-and-by we must get 

 into conversation. 



The exploration of the infra-world has given us a 

 vivid realisation of the relativity of time and space, 

 and has, I maintain, definitely delivered us from the 

 apparent necessity of providing a given time for a 

 given spell of existence. Life is thus to a great 

 extent delivered from the trammels of time, while 

 at the same time absolved from the confinement of 

 space. Life is superior both to space and time. 

 This has been instinctively felt by advanced minds 

 in all ages ; but here, perhaps, we have for the first 

 time a physical justification for such belief. 



It will, perhaps, be useful here to resume the main 

 conclusions of this essay : 



(1) The visible universe is only one in a chain of 

 similar universes contained one within the other, 

 and differing only in the size of then: elementary 

 constituent particles. 



(2) The atoms of one universe are the suns of 

 the next finer universe ; the electrons are its 

 planets.
