How a light wave can change its length depends on distance from the source? Am I stupid or this is a physical madness?
Every light have a temperature, it means every light have some wave lengts that constant in space, even on very high distance. Wavelenght may change when light source is moving, but still it's not affected by distance at all.
In other words - light temperature can't change at distance from the source. This is some kind of fantasy behavior of a light, maybe for artistic purposes... I don't know.
Really, you can get anything just with temp of light
