摘要

在汤川宇宙学中,最近的一项发现揭示了重子物质与暗部门之间的关系。这种关系由参数α和长程相互作用参数λ(引力子的内在属性)来描述。将不确定性关系应用于引力子会引发一个引人注目的问题:哈勃常数(H0)的测量精度是否存在量子力学限制?我们认为,引力子波长λ的不确定性关系可以用来解释哈勃常数随红移的变化。我们证明,时间的不确定性与哈勃常数的值呈反相关。这意味着哈勃常数的测量与长度尺度(红移)有内在联系,并与时间的不确定性有关。在宇宙学尺度上,我们发现时间的不确定性与回望时间量有关。对于红移值较高的测量,时间的不确定性较大,从而导致哈勃常数的值较小。相反,对于红移值较小的本地测量,时间的不确定性较小,从而导致哈勃常数的数值较大。因此,根据不确定性关系,哈勃张力被认为是宇宙学测量中固有的基本限制造成的。最后,我们的研究结果表明,引力子的质量随特定尺度波动,这表明引力子可能存在质量变化机制。

Addressing the Hubble tension in Yukawa cosmology?

In Yukawa cosmology, a recent discovery revealed a relationship between baryonic matter and the dark sector. The relation is described by the parameter α and the long-range interaction parameter λ - an intrinsic property of the graviton. Applying the uncertainty relation to the graviton raises a compelling question: Is there a quantum mechanical limit to the measurement precision of the Hubble constant (H0)? We argue that the uncertainty relation for the graviton wavelength λ can be used to explain a running of H0 with redshift. We show that the uncertainty in time has an inverse correlation with the value of the Hubble constant. That means that the measurement of the Hubble constant is intrinsically linked to length scales (redshift) and is connected to the uncertainty in time. On cosmological scales, we found that the uncertainty in time is related to the look-back time quantity. For measurements with a high redshift value, there is more uncertainty in time, which leads to a smaller value for the Hubble constant. Conversely, there is less uncertainty in time for local measurements with a smaller redshift value, resulting in a higher value for the Hubble constant. Therefore, due to the uncertainty relation, the Hubble tension is believed to arise from fundamental limitations inherent in cosmological measurements. Finally, our findings indicate that the mass of the graviton fluctuates with specific scales, suggesting a possible mass-varying mechanism for the graviton.
