Stick a couple of questions if I may:
1. what is the galactic centre?
2. As I understand it you are looking for points of maximim energy, and that occurs at the larange points, when earth is beyween two planets. That is also a point of movement equilibruim, yet energy maximisation?
3. What about 120 degrees? Surely we should be looking for aliignment which is 180 degress or 90 degrees, which represents maximium conflict?
The galactic center (I'm western Canadian so I do not use center spelling) is the center of our galaxy which is a black hole. As you get closer to the center star density increases drastically.
