Do you think measuring surface brightnesses of galaxies as a function of redshift is a practical method for testing cosmological models? explain the problems that might arise.

Explained

Explanation:

Cosmology has been a physical as well as experimental science with well defined method to test the cosmological model number number. The Surface brightness of galaxies are measured using various parameters. These parameters are magnitude N(m), number of red shifts N(Z), Magnitude red shift M(z), angular shift red- shift θ, surface brightness red shift J(z), age red shift f(z).

This a practical method for any of the cosmological model. These prediction could be used with a large telescope and distant object.
