I know this might seem very simplistic to some so don't bash or flame me, as I just want to learn. How exactly is energy made, or transfered, and what gives it the instruction to transfer? Is energy matterless or massless? I've used it in physics in equations and I know it is measured in joules, I just want to know the fundamentals and underlying concepts of it. I know the conservation of energy says that it cannot be created nor destroyed, but exactly where did it come from? If energy is massless does that mean that time doesn't exist for it? That it has been here since the beginning of the universe, just pushed around like a person frozen in a block of ice? Is energy only given off as a photon, and is limited only in the electromagnetic spectrum? Or is there energy present in gravity or weak or strong force? Are charge and energy one in the same? Because I'm fuzzy on both ideas on voltage (energy) and current (charge). Is the energy in voltage like the energy from visible light?
