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.
