The Yin/Yang Polarity Theory is a scientific term describing the energies that make up matter and antimatter.
It is said that each and every piece of matter and antimatter in the universe is composed of 2 polarities, one positive and one negative
The positive polarity creates positive effects to machines, organic life, etc. while the negative polarity causes the opposite, destroying machines, energy, organic material and anything that makes up any sort of matter or antimatter in the known universe.
The Edenians were able to harness these energies and split them into two different polarities allowing them to use them for certain means. Using the positive energy for powering engines for ships, medicine and for creating plants while the negative energy was used for weapons and other destructive means.
