Lets go little further in evaluating how light and colours are related, now that in this essay light is observed as by-product, which in manufacturing process often is discarded as disposable throw away. However, nature has some good uses for this light and because the source for light is fairly easy to manufacture, lot of earth’s surface is illuminated in various degree during dark hours. Although our sun is the most efficient natural source for light, yet all light sources behave the same way as sunlight. So light is continuously flowing bright but invisible streams in between source and illuminated object. Yes its puzzling but true. When light travels in between source and object its in transparent states, but when it lands on an object, light becomes an illuminator that is observable as the reflected light. In other words, light goes by our eyes at the speed of light all the time, but we don’t observe it until light lands on matter and illuminates it. Thus, light doesn’t travel as a wave or any kind of matter. What’s more, there are two kind lights we see all the time. The direct light from the light source and reflected that is coming from every direction, but we see it only as an illuminated surface. Therefore, light don’t have size nor weight. Hence, it’s another important factor to consider when evaluating the Red shift phenomenon. Because, colors are always related to mass but the light propagating through the space is 100% transparent, hence colors are not travelling with the light. Therefore, the color spectrum which science applies into the red shift theory. has limitations because all color formats has mass involved. In other words, all colors originate within mass particles. So, light is not the source for colors instead matter creates color. However, the question is what makes the natural color? The earth=s surface and atmosphere are good color producers but sunlight light we receive, makes no colors, in fact in various decrees colors are property from planets circling the sun, especially our well-known planet earth is bursting with colors, they only need to be illuminated. Consider this, within planet earth environment, natural lights are colourless at the beginning from the source, whether sources are sunlight or man-made. Therefore as natural light travels through space in between source and object, it carries no particles or any properties other than it illuminates all objects it lands on. In other words, light is invisible to an observer during it travels through space in between source and object whose colors it’s illuminating. Hence, there is no color spectrum available on the sun=s surface nor from the distant galaxy. Therefore, natural light doesn’t add colors. Instead it illuminates coloured surfaces. Obviously this old observation isn’t included in the Red Shift theory, because the theory is based on red and blue colors indicating whether a distant galaxy is moving away or toward the observer. However, based on all above, there are no colors nor color waves to observe until transpired light lands on observing elements and get misleading support for red shift theory. So how this works out, the invisible light beam from the distant galaxy originates from a huge area of galaxies, which are reduced into an observable tiny bright spot. So, from this bright spot the mass-less light is observable.
