The current big-bang cosmological model requires re-introduction of Einstein's "regretted" old cosmological constant to fit the astronomical measurements of supernova Ia magnitude versus redshift. The physical basis of the cosmological constant and the resulting acceleration of the universe are not supported by any other physical evidence and some advise caution in rushing to its acceptance. An altogether new cosmological model with only one adjustable parameter, the present age of the universe, does provide an excellent prediction of the supernova measurements without the cosmological constant. With a minimum description of the new model, a full set of equations is presented here sufficient to calculate the peak effective magnitude of a type Ia supernova for an input value of redshift Z and age t0. A full description of the model, together with many more falsifiable predictions, are presented elsewhere.
