宇宙费曼路径
Cosmological Feynman Paths
摘要：
矢状时间无发散规则或宇宙学量子动力学是通过跨越米尔恩时空宏观切片的阶梯费曼路径来制定的。切片的边界容纳着代表基本实体的完全相对论射线--前子。全相对论和相关的前子福克空间，尽管与狭义相对论（没有时间箭头）不同，但都是基于洛伦兹群。每条路径都是一组由直的、有向的和阶梯状的弧连接的立方体顶点，这些弧承载着惯性、电磁和引力作用。弧阶的作用包括增量，每个增量以普朗克常数为界。来自极远源的作用由宇宙平均能量密度决定。确定决定惯性作用的弧阶能量和决定引力作用的弧阶能量，就可以建立弧阶长度和宇宙密度。狭义相对论对于实验室时空尺度的物理学来说是精确的，远低于哈勃的，远高于普朗克的。
英文摘要：
Arrowed-time divergence-free rules or cosmological quantum dynamics are formulated through stepped Feynman paths across macroscopic slices of Milne spacetime. Slice boundaries house totally-relativistic rays representing elementary entities--preons. Total relativity and the associated preon Fock space, despite distinction from special relativity (which lacks time arrow), are based on the Lorentz group. Each path is a set of cubic vertices connected by straight, directed and stepped arcs that carry inertial, electromagnetic and gravitational action. The action of an arc step comprises increments each bounded by Planck's constant. Action from extremely-distant sources is determined by universe mean energy density. Identifying the arc-step energy that determines inertial action with that determining gravitational action establishes both arc-step length and universe density. Special relativity is accurate for physics at laboratory spacetime scales far below that of Hubble and far above that of Planck.
