与它试图取代的相对论不同，因果集合论（CST）被解释为为一种实质性的，尽管可能是“局部化的”，形式的“解释”留下了空间。从狭义相对论中得出的斯泰因定理的类似物在CST中不成立，这一事实滋养了基本生成的可能性。尽管如此，我们发现，在许多方面，关于成为的争论与它在相对论领域中遵循的反复演练的路线相似。然而，我们提出了一些新的曲折和挑战。特别是，我们表明，一个新的和异国情调的概念，成为兼容的因果集。与被其倡导者认为与CST动力学相容的局部化成为相反，我们的新型成为虽然不符合典型的A理论要求，但却是全球性的和客观的。1引言2因果集合论的基础3面临同样的困境？4认真对待增长5结论1引言2因果集合论的基础3面临同样的困境？4认真对待增长5结论
Unlike the relativity theory it seeks to replace, causal set theory (CST) has been interpreted to leave space for a substantive, though perhaps ‘localized’, form of ‘becoming’. The possibility of fundamental becoming is nourished by the fact that the analogue of Stein’s theorem from special relativity does not hold in CST. Despite this, we find that in many ways, the debate concerning becoming parallels the well-rehearsed lines it follows in the domain of relativity. We present, however, some new twists and challenges. In particular, we show that a novel and exotic notion of becoming is compatible with causal sets. In contrast to the localized becoming considered compatible with the dynamics of CST by its advocates, our novel kind of becoming, while not answering to the typical A-theoretic demands, is global and objective. 1 Introduction 2 The Basics of Causal Set Theory 3 Facing the Same Dilemma? 4 Taking Growth Seriously 5 Conclusion 1 Introduction 2 The Basics of Causal Set Theory 3 Facing the Same Dilemma? 4 Taking Growth Seriously 5 Conclusion
