Scientific paper

The application of Type Ia supernovae to cosmology has been briefly reviewed. Blue SNe Ia are better distance indicators, with relatively uniform spectra, light curves, and peak luminosity. The dispersion of SN Ia's peak luminosity could be further reduced via an empirical correlation of the peak luminosity with the light curve shapes. Once the absolute luminosity of SNe Ia could make constraints on the cosmic density parameters ΩM, ΩΛ as well as the deceleration factor q0, and hence determining the ultimate fate of our universe.
