本文提出 MOND 并非缺失物质的解答,而是暗物质在星系尺度动力学的唯象描述,由尺度相关自相互作用暗物质实现,并论证 ΛCDM 在宇宙学尺度上的优势。
AI 中文摘要
在这项工作中,我们旨在为 MOND 理论提出一个新的视角,即 MOND 理论并非对星系尺度缺失物质的解答,而是对暗物质在星系尺度上应产生的动力学的一种唯象描述。我们还旨在指出,星系尺度上的 MOND 动力学是由尺度相关的自相互作用暗物质实现的,这种暗物质根据尺度和物理过程的不同,可以表现为无碰撞的或碰撞的。为此,我们首先旨在强调 Λ-冷暗物质模型的成功之处,以及它如何压倒 MOND 范式。利用教科书物理,我们展示了 Λ-冷暗物质在宇宙学和星系团尺度上的成功,以及这些现象如何无法被 MOND 理论一致地描述。因此,通过排除 MOND 作为在所有尺度上对自然的可行描述,我们得出结论:MOND 可能并非牛顿星系动力学中缺失物质背后的答案,而只是展示了暗物质在星系尺度上的动力学应如何表现。
英文摘要
In this work we aim to present a new perspective for MOND theory, namely that MOND theory is not an answer for the missing matter at galactic scales, but it provides a phenomenological description of the dynamics that DM should produce at galactic scales. We also aim to point out that MOND dynamics at galactic scales is achieved by scale-dependent self-interacting dark matter, which can behave as collisionless and collisional, depending on the scales and the physical processes. To this end, we first aim to highlight the successes of the $Λ$-Cold-Dark-Matter model and how it overwhelms over the MOND paradigm. Using textbook physics, we present the successes of the $Λ$-Cold-Dark-Matter at cosmological and cluster scales, and how these phenomena cannot be described consistently by MOND theories. Thus, by excluding MOND as being a viable description of nature at all scales, we conclude that MOND may not be the answer behind missing matter in Newtonian galactic dynamics, but it is just showing how the dynamics of dark matter should behave at galactic scales.
