Starlight and Time by Russell Humphreys.
Hi. Have you ever seen this book before? I don't believe God is a deceiver, and I don't think young earth creationists are deceivers, either. P.S. I know both Russell Humphreys and John Baumgardner, astrophysicist and geophysicist, respectively, the two were formerly at Sandia and Los Alamos, respectively.
Dr. Russell Humphreys likes to use the jargon of time dilation to give viewers and listeners the impression he knows what he is talking about, and then he misuses that jargon in ways which demonstrate he fails to understand that jargon in the most fundamental ways. According to his claims about time dilation the passage of time on the Earth was necessarily much slower than at the most distantly viewed galaxies in order for the Creation of Earth to have only been some few thousands of years ago. Unfortunately for his attempt to take a conclusion and interpret the physical facts to reach that foregone conclusion, the distant galaxies would have to appear to us as very aged galaxies some tens of billions of years old for his Conjecture to work, whereas we are observing and viewing the exact opposite, with the most distant galaxies being very much slower in time due to their very high velocities, making those galaxies aged only millions of years instead of the billions of years that have passed in this region of the Universe. In other words, despite his alleged scientific credentials, he is speaking scientific nonsense falsified by observations of the realities.
