Type Ia Supernovae & the Distance Ladder: Advanced Connections

Type Ia supernovae extend the distance ladder far beyond Cepheid reach because they are enormously luminous. The ladder measures the local Hubble constant and tests consistency with values inferred from early-universe observations.

Once a supernova class is standardized and its absolute luminosity calibrated, observed flux gives luminosity distance.
