\textbf{Mass, Energy, Space And Time Systemic Theory }---MEST--- some suppose

Like charges repel each other, unlike charges attract, Like magnetic attract, unlike magnetic repel each other; By the same way, Like energy (like cold and heat) repel each other, unlike energy (as temperature, like cold and heat) attract, Like mass attract, unlike mass repel each other; so the dark mass-energy can give the planet the press like the gravity. Like revolution repel each other, unlike revolution attract, Like autorotation attract, unlike autorotation repel each other; By the same way, Like isospin repel each other, unlike isospin attract, Like spin attract, unlike spin repel each other; In the solar system, the mass-energy is center and the space-time is around. So sun absorb the mass-energy and radiate the light (space-time). In the black hole system, the space-time is center and the dark mass-energy is around. So black hole absorb the light and radiate the dark mass-energy. The dark mass-energy can go into sun. It can ignite the nuclear fission of sun. And the nuclear fission can ignite it's nuclear fusion ; The light can go into the black hole. It can ignite the ``nuclear fission'' of space-time of the black hole. And the ``nuclear fission'' can ignite the ``nuclear fusion'' of space-time of the black hole. When we get The Unification of Physics of MEST, we will get The Return-To-Zero of Physics of MEST. \[ f(x^{(M,E,S,T)})=(0,1) \]
