Does light travel??

When a ray of light travels from one medium to another, it bends from its straight path in according to snell's law. But a calculation would show that the path which we were talking about -- is the path that would take minimum time for light to show its effect there. My proposal: Light doesn't travel. Rather, light is a phenemenon which is taking place all over the universe with different phase lag and amplitude at different points in the space. When we get to observe the phemenon, depending on the phase lag and the amplitude, we conceptualize the following: 1. The source of the light. 2. The path traversed. 3. The speed of light. An analogy: is your computer screen. It seems that some animation is moving over it. But actually, it is the blinking of the pixels with a definite phase lag which makes it seem that the animation is moving. I short: "Light travel" seems to be, but is not the cause of the light being observed at a different place in the space. Rather, it is the phenemenon of light being observed at a point in space with a particular phase lag and intenity, which is the cause of the notion that light has travelled a particular path. What do you say?
