  In a series of articles, we have shown that the newly discovered
plasma-redshift cosmology gives a simpler, more accurate and consistent
explanation of many cosmological phenomena than the big-bang cosmology. The SNe
Ia observations are in better agreement with the magnitude-redshift relation
predicted by the plasma redshift than that predicted by the multi-parameter
big-bang cosmology. No deceleration or expansion parameters are needed. The
plasma-redshift cosmology is flat and quasi-static on a large scale. The Hubble
constant is no longer an expansion parameter, but is instead a measure of the
average electron density along the line of sight towards an object. Perusal of
the SNe Ia data and quasar data has shown that there is no time dilation. The
conventional estimates of the Hubble constant from gravitational lensing
observations use the big-bang cosmology for interpreting the observations. This
has lead to a large spread and discordant estimates of the Hubble constant. The
purpose of the present article is to show that the gravitational lensing
observations are in agreement with the plasma-redshift cosmology, and to show
how to evaluate the lensing observations based on the new plasma-redshift
cosmology. The lensing observations also indicate that the quasars have large
intrinsic redshifts.
