I have an idea that seems for me interesting and exotic. It is not about a traveling with speed of light or observing a frozen light. Rather it is about the nature of light/photons and discrete structure of space-time. No material object can move exactly with speed of lights (there is no much energy for it), it is impossible to observe an frozen light. But the space-time cells can be activated in a way that seems that light are moving with the known speed of it.
My question about cells of space-time and they are not material until activated. Can a photon not move in space in classical terms of understanding? Can it happen so that instead of moving along a straight line, the movement is obtained this way: after certain intervals of time certain points (the points of space-time not classics material points) in space-time structure are activated/deactivated. What I mean is that the light isn't moving in a way that the other macro objects are moving. I mean that light movement is some kind of wave of space-time points. Photon doesn't move continuously in space-time, rather it's a wave of space-time points and also according to this idea it becomes clear why the photon does not have a rest mass.
As an explanatory example I can give this analogy. Imagine that there is a display and a few pixels on it. At first the first pixel is turns on then it is turns off then the second one is turns on and after some time period it turns off and so consistently all the pixels. And for the outside observer is seems that the light is moving on (on the display). My idea is that on the space-time the light moves like in example above.
