I hear a lot of watching light from sun reaching at an interval of a couple of minutes, is a ray of light broken, with each blip having a distance of a few minutes, give or take a few seconds, or is it continous, non broken, as we see, so it is received in our eyes, as one single line of ray? or we talk when it is gone, will we know in some minutes and few seconds, this is understood, but a ray is continous or not? thanks.
