摘要

我们考虑了在宇宙学中应用广义相对论修正的背景下探索“理论空间”的一些认识上的好处。我们展示了如何研究广义相对论的修正可以帮助评估经验推断的稳健性，特别是在难以接近的制度。我们还讨论了在理论空间中明确区分明显不同方向的挑战。

Dark Energy or Modified Gravity?

Abstract We consider some of the epistemic benefits of exploring “theory space” in the context of modifications of general relativity with intended applications in cosmology. We show how studying modifications of general relativity can help in assessing the robustness of empirical inferences, particularly in inaccessible regimes. We also discuss challenges to sharply distinguishing apparently distinct directions in theory space.
