The Cosmic Microwave Background Temperature as Y/R: A Fundamental Derivation

Key Points

• To derive the temperature of the cosmic microwave background (CMB) as Y/R and assess its agreement with prior observations.
• Derivation of CMB temperature using Y/R formula.
• Comparison of derived value with Planck 2018 measurements.
• Analysis of historical measurements for convergence trends.
• Derived CMB temperature is 2.729 K.
• Achieves 0.13% agreement with Planck 2018 value of 2.7255 K.
• Historical measurements indicate a trend of convergence towards Y/R.
