The same processes are at work throughout the universe. Basically, it comes down to this—one force is producing energy and another force is taking the energy produced and using it for its own ends, and sometimes those ends are not what we would call positive. On one end of a spectrum we have selfless energy production. On the other end we have “selfish” use of the energy produced.
Autotrophs like green plants can make their own food. Heterotrophs like us cannot make our own food—we depend on autotrophs for our survival or we eat other heterotrophs. All living organisms have to have a supply of energy—you either produce it or you accrete it.
The same is true among human beings. The IMPACTS are the autotrophs—they produce the energy upon which the rest of humanity depends.
When you look at a binary star system where one star is dying and accreting matter and energy from the other, healthier star, it is the same process at work. If you don’t produce energy, you must accrete it from another entity or else you “die”.
Countries behave exactly the same way. International politics is actually the game of accretion—how can a country corral the energy-producing-IMPACTS and the natural resources that they can develop? Strip away all the wars and militaries and diplomats and that is what it is all about—getting a significant share of the IMPACTS and natural resources.
