I'm no astronomy/physics whiz, so I must ask the question...
Do they know for sure that the speed of light is the same in space than in atmospheric conditions?
Poll...

All theories and studies indicate that C is an absolute, one of the very few in our world.

It is a constant in empty space. Nothing can exceed the speed of light in empty space.
It does go slower through the air or other translucent materials depending on the refractive index of the material
Air speed is only slightly less than c, through water or glass as much as 2/3 to 3/4 of c.

Do they know for sure that the speed of light is the same in space than in atmospheric conditions? Light is slower in the atmosphere and even slower in water or glass. But the assumption that light moves at the speed of light in the vacuum is very major and is still an assumption. The theory of relativity plays with this concept a lot, so much that you could say the speed of light in a vacuum is not in general the speed of light in a vacuum. You can certainly not make the jump to the idea that nothing can go faster than the speed of light.
