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)
