The measurement of the Hubble constant using the Cosmic Microwave Background (CMB) relies on inputting parameters into which standard cosmological model?
Answer
The $ ext{LCDM}$ model
The Planck mission analyzes CMB fluctuations and fits these observations to the standard cosmological model ($ ext{LCDM}$), which describes the universe's composition (matter, radiation, dark energy $ ext{Lambda}$) to predict the current expansion rate.
