We all know the constant which stands for the speed of light in a vacuum.
However the speed of light is not constant, we can slow its speed to near zero right here on Earth (Scientific American). My question is, if the speed of light can be slowed, can it not also be increased? Supposed we could formulate an exotic material that could increase the speed of light when it passes through or near the material.
It is by the speed of light that we know the age of our Universe, just find the boundry and calculate the distance in light years it had to travel. But if light speed were variable, the Universe could be an infinite number of shapes.
