Dark matter and the dark energy are the biggest mystery for physics. But those characters are already elucidated by the energy body theory. The cosmological term in the Einstein field equations is “the universal repulsion” which becomes negative energy. Einstein supposed the regular Universe. It was very natural because of “the conservation law of energy”. But it looks like the universe expansion broke “the conservation law of energy” Also, in “energy body theory” the dark energy is negative energy too. It is the same as “the universal repulsion”. “The conservation law of energy” is endorsed by the Universe circulation system which is introduced by the energy body theory. After all, the universe is the regular Universe. The energy body theory describes that everything in the universe is energy body and all of phenomena in the Universe are caused by trying to balance the different energy level between two energy body systems. Energy body is comprised of energy cell bodies which are extremely smaller than elementary particles. Gravitational field is comprised of space layers where energy cell bodies are arranged on the spherical face. Dark matter is gravitational field. The dark energy is that expanded energy cell bodies are spread out around gravitational field. Dark energy is generated with a gravitational field as a pair. Elementary particles are the excitation states of energy cell bodies. Specifically, elementary particles are the states that energy cell bodies are shrinking, expanding, and more rotating.
