   This, of course, assumes the FLWR metric is applicable.   
      
   Are you familiar with Steinhardt's ekpyrotic theory?  He claims that the   
   "big bang" was very large to begin with and that model fits the experimental   
   data.  He seems to favor a cyclic model (I think) but there is no evidence   
   that the expansion will ever stop.
