Okay so im gonna drop a physics bomb on all yall So there are four forces of the universe Gravity witch is void Electromagnetism witch is ark Strong nuclear force would be Solar Weak nuclear force would envolve the 4th element Decay As op described void energy describes the force of gravity so theres not much one could go into there However op was incorrect about solar and arc Electromagnetism is by definition arc, or electricity. A mooving magnetic field creates an electric field and a mooving electric field creates a magnetic field. These two together osolate creating a wave witch james clerk maxwell prooved was light so ark is one of the fist elements used by the gaurdians because it is light there own weapon Thw strong nuclear force witch is so powerfull it holds the proton particals together ever since the begining of time. It also is the force that powers the sun and stars ergo solar energy. Stars envolve the weak nuclear force too witch makes it hard to argue the last part The weak nuclear force. This force governs radioactive decay, halflifes of particles, and sub atomic particles. The only viable element for this to represent would be a decay element in destiny
