This universe is the so-called clockwork organism. If a metagalaxy is compared to clock, each part of which that's composed will be each object (galaxy, star, elements, and atom). Those have to be equipped with the individuality in the purpose which is the organization. It's possible to be continuing this universe by existences with the peculiar feature in the size, the mass and speed harmonizing in one structure. The natural world is formed by such harmony principle. If it's so, to elucidate such mechanism of harmony has to be the main purpose of physical science. The key which solves the mystery is to concider natural law by the angle as the interaction of the substance and the energy. If we look back to history of physics, we will find that a study has developed through the angle of the approach action. But the natural reality couldn't be made that clearly. The methodology reached the limit already, and it didn't seem to lead any more development by such approach. A completely new way of thinking is needed for us to get correct and deep understanding to nature at present. I thought the members in this world are harmonized by exerting the force and the energy each other by a remote action and produced relational physics newly. As a result, I succeeded to explain all force which exists in the natural world in one structure.
