Theoretical physics research on a fundamental alternative to quantum field theory called Quantum Net Dynamics (QND) will be carried out. The net in question is a discrete quantum microscopic causal structure hypothesized for spacetime. QND is local, locally finite, locally relativistic and has a fundamental construct with the dimensions of time supposed to set the scales of times, energies, and lengths of high-energy physics. QND permits a quantum condensation that approaches Minikowski spacetime and the Dirac equation for times large compared to the fundamental time. The QND analogue of Feynman diagram calculational rules will be studied with an eye to practical high-energy particle calculations free of ultraviolet infinities. Quantum field theory is essentially the only known approach to practical calculations in elementary particle physics. Since quantum field theory does have its shortcomings, studies of alternatives, such as the study to be undertaken here, are valuable.

一种基本替代方案的理论物理研究 量子网络动力学（Quantum Net Dynamics，QND） 执行。 这个网络是一个离散的量子 为时空假设的微观因果结构。 qnd 是局部的，局部有限的，局部相对论的， 时间维度的基本概念 设定高能量的时间、能量和长度的尺度， 物理学 QND允许量子凝聚， Minikowski时空和倍大的Dirac方程 与基本时间相比。 Feynman的QND模拟 图表计算规则将着眼于研究 实用的高能粒子计算， 紫外线无限大 量子场论基本上是唯一已知的 基本粒子实用计算方法 物理学 因为量子场论确实有其 缺点，替代方案的研究，如研究将 在这里进行，是有价值的。
