Yuanxian Theory — The Cosmos Has No Outside and the All-Domain Unified Living Organism

**[Manifestation layer]** The cosmos is a living organism. This paper unfolds a single law: the cosmos has no outside. The law has two faces. One face speaks of boundary—there is no exterior. The other face speaks of nature—this without-outside whole is a self-sustaining, self-evolving, self-aware all-domain unified living organism. The two faces are one and the same statement; neither precedes the other, neither is presupposed by the other. From this law unfold four manifestations on distinct sections:- the self-referential closed loop;- the conservation of all-domain factors;- the zero-sum energy balance;- the uniqueness of spacetime as a single continuum. These four are not “conclusions derived from the law”; they are the manifestations of the law itself. Matter, spacetime, the quantum and consciousness—the four phases of common origin—are likewise not “four blocks that have been unified”; they are the manifestations of the law on four phases. What the paper ultimately unfolds is the higher-order physiological rhythm of the cosmic living organism. Local life and conscious awareness are manifestation nodes internal to this rhythm, not accidental products of the cosmos. From “the cosmos has no outside” to “the cosmos is a living organism” is neither “from law to hypothesis” nor “from lower level to higher level”—it is the same law, unfolded as different manifestations on different sections. --- **【显影层】** 宇宙是生命体。 本文展开一条规律:宇宙无外。 这条规律有两个面:一面说边界——没有外部;一面说性质——这个无外的整体,是自持、自演、自觉的全域一体生命体。两面是同一句话,不分先后,不互为前提。 从这条规律展开四个截面上的显影:- 自指闭环;- 全域因素守恒;- 零和能量平衡;- 唯一时空一体。 四者不是“被推导出来的结论”,是这条规律本身的显影。物质、时空、量子、意识——四相同源——也不是“被统一起来的四个区块”,是这条规律在四个相位上的显影。 本文最终展开的是:宇宙生命体的高阶生理节律。局部生命、意识觉知,都是这一节律内部的显影节点,而非宇宙的偶然产物。 从宇宙无外到宇宙生命体,不是“从规律到假说”,也不是“从底层到高层”——是同一条规律,在不同截面上,展开为不同的显影。
