I wrote up the argument of my last post a bit more carefully and sent it off to the American Journal of Physics as a comment on the original article by Styer. Here’s a PDF of the submitted version. I tried to clean up the argument and fill in some gaps, but nothing substantial has changed.
I am chair of the physics department at the University of Richmond. In addition to teaching a variety of undergraduate physics courses, I work on a variety of research projects in cosmology, the study of the origin, structure, and evolution of the Universe. University of Richmond undergraduates are involved in all aspects of this research. If you want to know more about my research, ask me! View all posts by Ted Bunn
