I'm a fan of human space technologies , and often ponder on the implications of human space travel, development of human colonies if foreign worlds. Naturally the establishment of these colonies would be to secure resources for the Mother Planet, Earth. However, with the passing of time some of these inner colony worlds would grow in size as well as influence with other peripheral colonies. The problem would be if say these core colony worlds will see the futility in maintaining relations with the Home World and declare independence, rebel. The Mother World would be threatened since there would be a reduction and loss of resources , vital minerals that these home worlds had provided Earth in the past.
I wonder how it would be like -- a Human Galactic War -- imagine The Home World mobilizing fleets and ground forces to invade these colonies with the goal of maintaining the status quo , or the 'Galactic Order'.
Hmmm... your view?
