Honestly krash is it not me who does not know what I am talking about, my first forum several years ago my idea was that light was transparent, because in the open space between my eyes and an object it is invisible, no spectrum, colourless, etc.you should take your own advice.
I then realised my error, and it was the dark that is transparent to light and the dark is the constant state and natural of the Universe. It is not even hard to understand, the Sun is a black body, the emitting ''light'' travels in a linearity so fast that the effect is invisible until it is in interaction and then becomes a wave.
