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 Cepheid stars.

Question

Quizplus · Accepted Answer

Type I supernovae are used as a standard candle to measure distances to very distant galaxies, but their accuracy is dependent on the calibration of Cepheid stars, which are used as a secondary standard candle to calibrate the distance modulus of Type I supernovae. Therefore, the statement is true.
