A Hypothetical Model of the Universe Based on Cosmic Microwave Background Radiation and the Observable Universe (Part II)

The standard cosmological model continuously revises the age of the Universe based on redshift observations (e.g., discussions ranging from 13.8 billion to 26.7 billion years). This paper clarifies the underlying logic of such revisions: the model establishes an equivalence between “distance” and “time”, which relies on a fundamental assumption — that the central point of the Big Bang is implicitly placed on the timeline of the observable Universe. This paper does not judge the validity of this assumption, but only compares it with the hypothetical premise proposed in the first paper that “the central point lies outside the observable Universe”. The two assumptions lead to drastically different logical conclusions: under the former, continuous upward revision of the cosmic age is logically inevitable; under the latter, such adjustments become unnecessary. On this basis, this paper further proposes several hypothetical phenomena that can be tested by future observations, including observable variations in total matter content, the existence of large-scale coherent motions, an intrinsic component in the CMB dipole, and the trend of continuous upward revision of the cosmic age.
