There are clouds in the universe, and also there are clouds in the earth. When we see images of clouds, how can we distinguish them from one another. Because we never experienced the universe, we have not enough clue to say where this images of clouds came from. In this circumstances, fiction is not inferior to what is considered reality. If we can't tell the difference between them, there is no reason I can't say these images are from the universe. Therefore, I call them 'Space Cloud'.
