Small Article: How Constant Is A Constant?

Article: How constant is a contant? It turns out that a number of physicists have proposed that the speed of light varies. The idea that the speed of light in the past cone of the universe was many multiples of c, seemed to remove many cosmological problems. One that I can think of off the top of my head, is the time it requires to allow light to reach all four corners of the universe. In order to create a balance in the equations with observational evidence of the background temperatures, an inflationary period was introduced. This moment which allowed the universe to expand faster than light itself, allowed light to reach all four corners of the universe, and create a homogeneous background of gamma particles. If we did not have this inflationary period, we would see clumps of the background radiation showing different temperatures, but this is not the case. Immediately, one can deduct, that if light speed was many more times c, it would remove this problem, and without need of some phenomenal inflationary period that occurs around -33 and -35 seconds after big bang. The scientists I refer to at the beginning of the post, include V.S. Troitskii [1] who proposes that the speed of light was initially 10^10 times the general speed of c, Moffat [2] who proposed it be a value which has dropped over the billions of years since big bang, Albrecht and Magueijo [3] who agreed with Moffat and proposed a whopping value of c that was 10^60 times the value of c, and John Barrow [4] who agreed with that value, who proposed it dropped over the lifetime of the cosmos, instead of proposing it be immediately after big bang.
