Moffat Reinventing Gravity
In 1992 Moffat submitted a paper to Physical Review D. The referees were outraged and his paper was rejected. In 1993 Moffatt's paper was finally accepted by the International Journal of Modern Physics D. Years later he came across the Albrecht-Maguiejo paper on the speed of light, which was written completely independently. As for precedence, Lord Kelvin claimed a changing c in a paper published in 1875!
In his new book REINVENTING GRAVITY, Moffat discusses everything from the speed of light to extra dimensions. From Chapter 6:
INFLATION AND THE VARIABLE SPEED OF LIGHT [VSL]
Given the chances of inflation happening in the early universe are so slim--and the phenomenon could only come about by extreme fine tuning--the sensible reader might ask: Is inflation actually an improvement over the original big bang model? Is it 40percent better? Or perhaps only 10 percent better? When one considers the problems of inflation in this way, the original motivation for inflation as a solution to the initial conditions of the universe is somewhat diminished...
WILL THE DATA DISCRIMINATE BETWEEN INFLATION AND VSL?
Despite problems and criticisms over the years, inflation has become accepted as a realistic picture of what happened in the very early universe. Why is more attention not paid to VSL, which is an alternative to inflation, solves the horizon and flatness problems, and predicts a scale-invariant spectrum of quantum fluctuations in agreement with experimental data? The answer may be more sociological than scientific. Inflation has been around a dozen years longer than VSL, and it is often easier to support the incumbent and not bother looking very deply into the qualifications of the challenger.
