Sound passes through a medium where it can have elements that move in concert, the medium maybe modified by gravity but the sound is not. There is no sound in space for its either does not carry the vibrations of sound.So that raises the question what does light pass through; traditional physicists will tell you it travels something like subspace, maybe the either that holds antimatter which they will tell you is another dimension to space; LMAO can not see it, never will. There are only 3 dimensions to space and thus object are confined to 3d space as is its vibrations and plasma displays, they just do it in a state of matter that exists apart from ours.
How could light go straight is it has to move from one dimension to another before you can view it, rofl.
If light is passing through a space apart it could not be seen in this space, so the space would have to be embedded within our space, for it to be in both spaces simultaneously.
The speed of light is not absolute, that was proved a few decades ago. It too is dependent upon the medium it passes. So in essence it does pass through 3d space and not some other continuum; it just has no mass and goes extremely fast in certain mediums. If you could stop it, then you could modify it before restarting it; this is one path towards invisibility.
