没有质量的物质：我们真的需要质量的概念吗？
Matter without mass: do we really need the concept of mass?
摘要：
爱因斯坦最著名的方程-- $E=mc^2$ --在质量和能量的概念之间产生了短路，这也影响了物质、辐射和真空等其他概念。物理学目前混合了经典的、相对论的和量子的质量概念，这产生了大量的混乱和许多问题。如果想要避免捉鬼，就需要建立明确的定义。特别是，通过放弃质量的概念，专注于时间和能量，一些有趣的含义正在出现。注意到量子真空能量的截止频率与观测到的宇宙学常数一致，对应于宇宙微波背景的截止频率。这可能与克尔-德西特度规所描述的宇宙旋转膨胀的假设一致，该度规具有观测到的宇宙学常数。验证这一假设对于证明宇宙的旋转至关重要。
英文摘要：
Einstein's most famous equation -- $E=mc^2$ -- generated a short-circuit between the concepts of mass and energy, which also affects other concepts like matter, radiation, and vacuum. Physics currently has a mixture of classical, relativistic, and quantum concepts of mass, which generates a great deal of confusion and many problems. Clear definitions need to be established if one wants to avoid ghost hunting. In particular, by abandoning the idea of mass and focusing on time and energy, some interesting implications are emerging. It is noted that the cutoff frequency of the quantum vacuum energy, consistent with the observations of the cosmological constant, corresponds to that of the Cosmic Microwave Background. This might be consistent with the hypothesis of a rotating and expanding universe described by a Kerr-de Sitter metric with the observed cosmological constant. To verify this hypothesis is crucial to prove the rotation of the universe.
