Abstract
A tired light/contracting universe (TLCU) model is shown to be an excellent fit to the redshift/distance modulus data for the 580 supernovae 1a in the Union2.1 compilation. The data reveal that the Milky Way is in a static region with a radius of about 450 Mpc. Beyond the static region the universe is contracting with a space velocity which is linearly proportional to distance over the whole range of the data ( K= − 7.6 ± 2.3km ⋅ s − 1 ⋅ Mpc − 1 ). The other constant of the model is the Hubble constant for which a value of H =69.51 ± 0.86 km ⋅ s − 1 ⋅ Mpc − 1 is obtained. The fit of the TLCU model to the Union2.1 data is at least as good as the fit of the two constant ΛCDM model to the same data. A formula for photon travel distance is derived and an experiment for the possible detection of the tired light process is proposed.
