"The whole 100% universe is shown in the CMB with no different areas. Fine-tuning is accepted as universal. Your thinking is oddball."

There is a new study of the CMB showing one segment is slightly different:

"A Reassessment of Hemispherical Power Asymmetry in CMB Temperature Data from Planck PR4 using LVE method

"We undertake a reassessment of one of the large angular scale anomalies observed in cosmic microwave background (CMB) temperature signal referred to as Hemispherical Power Asymmetry (HPA).

***

"Our emphasis here was to revalidate the LVE method in various ways for its optimal usage and probe the hemispherical power asymmetry in the form of a dipole modulation field underlying CMB sky. By and large, our results are in agreement with earlier reported ones with more detailed presentation of explicit and not-so-explicit assumptions involved in the estimation process. The above reported values fall in the reliability range of LVE method after this extensive re-evaluation. We conclude that the hemispherical power asymmetry still remains as a challenge to the standard model."

Comment: a minor asymmetry exists between the two hemispheres of the CMB. This does challenge the standard model. It does not challenge that the universe originated as fine-tuned for life.
