  Recent observations on the redshift and magnitude of distant supernovae have
raised fundamental questions of the cosmological structure and the development
of space. Interpretation of the observations with the standard cosmology model
suggests accelerating expansion of space which requires an assumption of
unknown dark energy working against gravitation at cosmological distances. This
paper presents an analysis which shows that the observed magnitude redshift
relationship is in an excellent agreement with the prediction derived by
assuming a zero energy balance of motion and gravitation in an expanding
4-sphere. Such an approach can be regarded as Einstein-deSitter expansion in
the fourth dimension, suggesting a decelerating expansion velocity until zero
in infinity.
