So far, man has discovered 3 forms of energy which make up the universe, everything seen and unseen. One form is radiating, or positive energy, of which there are two general types: electromagnetic energy and the weak force (nuclear decay). The sun, carbon burning and the heat of our own bodies are the most familiar examples of radiant energy. Radiant energy is a result of chemical reactions of matter, and is carried by bosons, such as photons, which are elementary particles.
Matter is made of elementary charged particles of energy (Fermions) and their combinations held together by contractive (negative) energy, the known different levels being the strong force, nuclear force and gravity.
The interesting thing is that elementary bosons and fermions are exactly the same bits of energy. The only difference is their spin: bosons have 1, fermions ½ (either plus or minus). The double spin for bosons (photons) somehow allows them to be indiscreet, so they can be in the same place at the same time. On the other hand, fermions (the basis of matter) are discrete, thus cannot be in the same place at the same time. That's why matter seems to be “solid.” The virtual nature of photons, considered with their mass of 0, qualifies them as non-matter. However, it’s important to note that light, although non-matter, is still individuated (in the form of separate quanta/photons/waves).
The third form is dark energy. Also known as vacuum energy, it's a complete mystery. It is truly supernatural, beyond anything in nature. It is formless and omnipresent, permeating the universe, present in all space. It is undifferentiated and unobserved. The only evidence of its existence is its necessity in order to explain how the rest of the universe acts.
