Several decades of theory and experiment into EPR correlations have led to the widely held belief that reality is non-local, in spite of the fact that this violates special relativity. To date, no experiment has shown a violation of special relativity, and EPR experiments do not demonstrate the existence of superluminal information exchange, merely correlations which violate certain inequalities. Every “loophole” in these hidden variable theories has been thought plugged. However, there is much confusion in the literature due to conflation of the terms “locality,” “realism,” “hidden variables,” “non-contextuality.” The presence of local hidden variables is thought to necessarily lead to a Kolmogorov probability structure (hence non-contextuality), but this is an assumption, one which is not true in general once context effects are taken into account. Treated as an observational theory, several authors have shown no incompatibility between quantum mechanics and locality, and that the Bell scenario is actually about whether reality is contextual. This paper proposes a descriptive theory by assuming a generated reality (following Whitehead's Process Theory) which can violate the principle of continuity and possess non-Kolmogorov probability structure, and reproduce the results of non-relativistic quantum mechanics, while allowing only causally local information exchange without hidden variables. A generated reality is thus compatible with both quantum mechanics and special relativity, reproducing all of the results expected from quantum mechanics while still maintaining causally local realism. This process model thus appears to be an ideal candidate for developing theories for the unification of quantum mechanics and general relativity.

尽管EPR相关性违反了相对论,但数十年来对EPR相关性的理论和实验导致人们普遍认为现实是非本地的。迄今为止,还没有实验表明违反了狭义相对论,EPR实验还没有证明存在超光速信息交换,只是证明了违反某些不等式的相关性。这些隐藏的变量理论中的每个“漏洞”都被认为是堵塞的。但是,由于术语“局部性”,“现实主义”,“隐藏变量”,“非上下文性”的混用,文献中存在很多混乱。局部隐藏变量的存在被认为必然导致Kolmogorov概率结构(因此没有上下文),但这是一个假设,一旦考虑到上下文效应,这通常是不正确的。作为观察理论,几位作者没有证明量子力学和局部性之间不兼容,并且贝尔的情景实际上是关于现实是否是上下文的。本文提出了一种描述性理论,假设存在一个现实世界(遵循怀特海德过程理论),该现实世界可能违反连续性原理并拥有非柯尔莫哥洛夫概率结构,并再现非相对论量子力学的结果,而仅允许因果关系进行局部信息交换没有隐藏的变量。因此,生成的现实与量子力学和狭义相对论都兼容,在保留因果关系的局部现实主义的同时,再现了量子力学的所有预期结果。
