Variable speed of light resulting in every physical quantity being normalized against its corresponding Planck unit. For that, it has been claimed that specifying the evolution of a dimensional quantity is meaningless and does not make sense. When Planck units are used and such equations of physical law are expressed in this nondimensionalized form, no dimensional physical constants such as "c", "G", "ħ", "ε", nor "k" remain, only dimensionless quantities. Short of their anthropometric unit dependence, there simply is no speed of light, gravitational constant, nor Planck's constant, remaining in mathematical expressions of physical reality to be subject to such hypothetical variation. For example,
In the Light of What We Know when the true pleasure of a work of fiction is its gravitational pull upon us?” In a 4,000-word review for "The New Yorker", the critic James Wood described Rahman as “a deep and subtle storyteller,” and praised the novel as “astonishingly achieved…Isn’t this kind of thinking—worldly and personal, abstract and concrete, essayistic and dramatic—exactly what the novel is for? How it justifies itself as a form?…"In the Light of What We Know" is what Salman Rushdie once called an ‘everything novel.’ It is wide-armed, hospitable, disputatious, worldly, cerebral. Ideas and provocations abound on every page.” Australian literary critic Louise Adler
