The debate between ΛCDM and MOND is often cast in terms of competing gravitational theories. However, recent philosophical discussion suggests that the ΛCDM-MOND debate demonstrates the challenges of multiscale modeling in the context of cosmological scales. I extend this discussion and explore what happens when the debate is thought to be about modeling rather than about theory, offering a model-focused interpretation of the ΛCDM-MOND debate. This analysis shows how a model-focused interpretation of the debate provides a better understanding of challenges associated with extension to a different scale or domain, which are tied to commitments about explanatory fit.
ΛCDM 和 MOND 之间的争论通常是在竞争的引力理论的基础上展开的。然而,最近的哲学讨论表明,在宇宙学尺度上,ΛCDM-MOND 争论表明了多尺度建模的挑战。我扩展了这一讨论,并探讨了当争论被认为是关于建模而不是关于理论时会发生什么,提供了对 ΛCDM-MOND 争论的一种以模型为中心的解释。这种分析表明,对争论的以模型为中心的解释如何提供了对与扩展到不同尺度或领域相关的挑战的更好理解,这些挑战与解释性契合的承诺有关。
