What specific spectral shape closely matches the measured CMB radiation, supporting the Big Bang model?
Answer
A perfect black-body spectrum
The CMB follows a perfect black-body spectrum, meaning its radiation intensity is purely dependent on its temperature, which is considered strong evidence for the Big Bang model.
