How do you messure the speed of light - in air or in vacuum - in order to properly be able to set up the formulas in the theory of relativity? And then if it is in air, how do you explain that different colors travels in different speeds?|||the speed of light as we know it is based on the structure of the space around us but may actually vary in different parts of the universe. the age of our sun and the processes that it goes through determine the make-up of our region of space.
other star systems at varying levels of development and size convert elements into heavier elements. heavy elements are unstable to us and decay but may be the norm around other systems, especially the ones that have gone nova and seed the space around it with this exotic material which eventually forms new stellar and planetary systems.
read the link below and you will see that light is manipulated when it goes through exotic materials. therefore the speed of light is determined by our placement in the universe and how light reacts as it crosses the spacial material from it's source to our eyes.|||vacuum.|||vacuum|||The theory of relativity mandates that the velocity of propogation of light through vacum is a constant value.

The different colours of light come from different frequencies - they all travel at the same speed.|||The velocity of light is a constant.It is never the velocity of less than light or the velocity of greater than light.|||The theory of relativity depends on the speed of light in a vacuum. It *is* possible to go faster than the speed of light in air. When that happens, Cerenkov radiation is released.|||Vacuum. There are too many variables with air.|||I think you are confusing wavelength with speed. ALL light travels at C.
