Coincidence of Universe Age in {\Lambda }CDM and Milne Cosmologies

M. Kutschera, M. Dyrda

The age of the Universe in the {\Lambda }CDM cosmology with {\Omega }{matter}=0.26 and {\Omega }{\Lambda }=0.74 is the same as in the Milne cosmology which corresponds to an almost empty universe. In both cases it is a reciprocal Hubble constant, 1/H0, that for now preferred value H0=71 km/s/Mpc is 13.7 billion years. The most curious coincidence is that at the present time, in the {\Lambda }CDM model the decelerated expansion is exactly compensated by the accelerated expansion, as if the Universe coast for 13.7 billion years.
