We found out from the voyager probe that the vacuum of space isn't uniform. The density changes although it is a small change it means we can't verify density over light-years of distance. Anything clear, with a change in density, would refract light due to Snell’s law. Small pockets of clear...

So your saying we can see all the locations that refract the light? What I am saying that it is possible for the light of any particular star to be refracted thousand of times before it even reaches us. Every time the light goes through a small cloud of debris. Even if the light refracts just...

When I was in the navy we used sound underwater a lot, so much in fact that we had equations capable of mapping out a sound rays path. Now, when it came down to mapping out the paths of sound the equations came from snells law. Snells law applies to ray paths in general. So both sound and light...
