   entropy and gravitation

   A smooth distribution corresponds to high entropy and a lumpy one to low   
   entropy if gravity is not involved.  For example, air in a room has high   
   entropy, but all the oxygen in one part and all the nitrogen in another   
   part would correspond to low entropy.   
      
   If gravity is involved, however, things are reversed: a lumpy   
   distribution (e.g. everything in black holes) has a high entropy and a   
   smooth distribution (e.g. the early universe) has a low entropy.   
      
   Let's imagine the early universe---a smooth, low-entropy   
   distribution---and imagine gravity becoming weaker and weaker (by   
   changing the gravitational constant).  Can we make G arbitrarily small   
   and the smooth distribution will still have low entropy?  This seems   
   strange: an ARBITRARILY SMALL G makes a smooth distribution have a low   
   entropy.  On the other hand, it seems strange that the entropy should   
   change at some value of G.
