Upsides To Making A Portal To Heaven  
    To  Build   The   Factory   There   
  
                                          
 First  Of All,  Real Estate:  The Highly 
 Fractalized  Geometry  (Not  Proven  But 
 Likely  To Be The  Case)  Implies Almost 
 Unlimited Room; Even If The  Portal Tech 
 Would  Be  Stolen,  Chances  Of  Running 
 Into  A  Competitor  Is  Close  To None, 
                                          
 Secondly,  The  Resources:  Heavens  Own 
 Alchemical   Properties  (Proof  Exist!) 
 Makes  Most  Base  Materials  Easily And 
 Readily  Available.  Once  The Molecular 
 Movement  Patterns  Are  Mapped Out, Any 
 Compound   Can   Be  Created   Virtually 
 Without                            Cost. 
                                          
                                          
  
   Downsides  To  Making A  Portal To   
  Heaven To Build  The  Factory There   
  
                                          
 Current Portal  Tech  Takes  Some Energy 
 To Hold Open, Which Isn'T  A Problem  In 
 Itself.  Test Results However Has  Shown 
 That  Without An Active Tether, Heaven'S 
 Time Flow Breaks  Down Completely.  Even 
 A Momentary  Fluctuation  Of  The Portal 
 Would   Render   All    Remote    Assets 
 Practically  Lost.  Much  Care  Must  Be 
 Taken  To  Maintain  Portal   Stability. 
 (One  Option Could  Be Several  Portals)
