When we measure distances to very faint galaxies with Type I supernovae,the accuracy of the measurement is only as good as that of the calibration of the Cepheids.

Question

Quizplus · Accepted Answer

Type I supernovae are calibrated using Cepheid variables as distance indicators, so the accuracy of the distance measurement to faint galaxies with Type I supernovae is limited by the accuracy of the calibration of the Cepheids.
