I read in Wired a while ago about how light is affected by gravity or some other such fundamental force, and thus the speed of light varys throughout the universe. Does this hold any water anymore, or is it just baloney? I did a quick search on VSL through google and found an article, but the math was way above my head; perhaps someone could read this article and maybe explain it in laymans terms for my benefit.
