Abstract
The age of the Universe in the CDM cosmology with and is the same as in the Milne cosmology which correspods to an almost empty universe. In both cases it is a reciprocal Hubble constant, , that for now preferred value is 13.7 billion years. The most curious coincidence is that at the present time, in the CDM model the decelerated expansion is exactly compensated by the accelerated expansion, as if the Universe coast for 13.7 billion years.
