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:关于模型或理论的辩论?

ΛCDM 和 MOND 之间的争论通常是在相互竞争的引力理论方面进行的。然而,最近的哲学讨论表明,ΛCDM-MOND 辩论表明了在宇宙学尺度背景下多尺度建模的挑战。我扩展了这个讨论并探讨了当辩论被认为是关于建模而不是关于理论时会发生什么,提供对 ΛCDM-MOND 辩论的以模型为中心的解释。该分析显示了以模型为中心的辩论解释如何更好地理解与扩展到不同规模或领域相关的挑战,这些挑战与解释契合的承诺相关。
