   What about time?   
      
   An aribtrarily small G will take an almost infinite time to manifest   
   itself. Weaker gravity will EVENTUALLY get matter clumpy but if gravity   
   is weak, it will take MUCH more time for gravity effects to manifest   
   themselves.   
      
   An arbitrarily small gravity will take arbitrarily long time to have any   
   effect.   
      
   Does the contradiction disappear if we take time into the picture?
