for light to get from one distant region 
      to another, even though the regions
      were close together in the early 
      universe.  According to the theory of 
      relativity, if light cannot get from one
      region to another, no other      	      
      information can.  So there would be no 
      way in which different regions in the 
      early universe could have come to 	
      have had the same temperature as each 
      other, unless for some unexplained 
      reason they happened to start out with 
      the same temperature.

(3) Why did the universe start out with so   
      nearly the critical rate of expansion 
      that separates models that recollapse 
      from those that go on expanding for      
      ever, so that even now, ten thousand 	
      million years later, it is still expanding 
      at nearly the critical rate?  If the rate
