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)
