*10. Jefimenko, O.D. 1997. Electromagnetic Retardation and Theory of Relativity, Electret Scientific Co., Star City, W. Virginia, Chapter 10 I came across this article and I was just wondering about the above comment about clocks. It seems to suggest that clocks will slow down by a rate equivalent to the Lorentz factor as a result of gravitational effects acting on time-keeping mechanisms, without the need to invoke "time" dilation. I was just wondering about the veracity of that statement.
