Light has both particle and wave properties, so it is not reasonable to compare light to sound as you have done. Furthermore, light can "travel" through a void, a vacuum--whereas sound has to be transmitted through some physical medium. The speed of sound is not a constant, it depends upon the material through which it is transmitted.

Is your response attributable to you lack of a command of the English language . . . or are you just goofy?

Or, a third possibility is that you are not currently in control of your senses due to drinking / using certain substances?

I just have to correct this. The speed of light also depends upon the material through which it is transmitted.

The speed of light in a vacuum is a constant. Light travels slower (often considerably slower) though matter. If this weren't true, then light wouldn't be bent by glass, meaning lenses and prisms wouldn't work.

And you wouldn't see the blue glow of Cherenkov radiation in pools of water with reactor fuel rods at the bottom.

I doubt many of us have seen the blue glow of Cherenkov radiation in pools of water with reactor fuel rods at the bottom.

But many of us know about it from books and pictures. (rolls eyes) I have know about it since the age of 9 approx (around 1961)

light does not need a medium in order to reach out , into

sound needs a medium , such as air
