This totally defies the speed theory. Photons slow down. Only one stellar distance measurement is reliable. Keep in mind that only one method of ascertaining stellar distances is accurate. It is the parallax method, which can only be used on a few of the closest stars.
Quasars are a great headache to evolutionists, for they clearly disprove the speed theory.
And without the speed theory there can be no expanding universe. Quasars may hold the key to an understanding of the redshift . According to the speed theory of redshift, quasars must be the most distant objects in the universe. The fact that quasars can be seen through optical telescopes, yet are supposed to so far away, violates the inverse-square law. In 1973, a quasar was found which had a speed redshift of 350 percent.
