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,
A Slower Speed of Light toolkit allows for the accurate simulation of a 3D environment when light is slowed down. It is hosted on GitHub and has been published under the permissive MIT license. "A Slower Speed of Light" was developed in hopes of being used as an educational tool to explain special relativity in an easy-to-understand fashion. The game is meant to be used as an interactive learning tool for those interested in physics. A Slower Speed of Light A Slower Speed of Light is a freeware video game developed by MIT Game Lab that demonstrates the effects of special relativity by gradually slowing
