The study of space physics brought Eugene Savov to essentially new and complete picture of the universe described in his book Theory of Interaction. He draws a universe made of self-reproducing, self-similar (fractal) interactions. These multiscale similar interactions build everything and clearly explain the dark matter, the normal galaxies and the fringes of the accessible universe and many confusing observations. For more information you should see the web site http://www.eugenesavov.com. Here you can make free downloads that describe the fractal "firework universe" presented by the author of the theory of interaction. It seems that the current understanding of the universe can be obtained as a case from one fractal interaction? Could the concept of fractal transforms be so powerful?
