Astronomy
The oldest light
Stretch the early Universe’s thermal light. Change the redshift and the angular texture scale to separate the mean temperature from tiny fluctuations.
The model and its limits
T = T₀(1+z), Wien’s law and a synthetic fluctuation field. This is not a Planck map or a calculated angular power spectrum; colours magnify microkelvin variations.
Equations used in the module
Equations T(z)=T₀(1+z); λ_peak T = 2897.772 μm K; T₀=2.7255 K
