Small demo representing how spirals are forming in galaxies.

This demonstration can seem to people all its life having deal with
Astronomy, Astrophysics, Cosmology and other serious sciences, to look radical pseudoscientific. It that possible that serious people, Professors, Doctors of Sciences, Academics about 100 years rack their brains and can not understand how this is possible that spiral arms of galaxies exist and does not desintegrate while rotating around the galaxy center? How the double spiral is formed? Why the arms of the arms of the spiral so symmetrical? What is forming a bar, or bridje, or bulge in the center of a galaxy and what is the difference between them?

And suddenly an unknown man comes and says: look, this is simple. Spiral arms are just two four perpendicular streams of plasma moving from the center of the galaxy to its bounds. And while each spot of plasma is moving over straight line from the center to the bounds of the galaxy, its source in the center of the galaxy is rotating slowly forming a double spiral.

That's all. And there is no necessity in a dark matter to provide rotating galaxies as solid  bodies. And there is no needs in squared orbits of stars around the galaxy allowing them to jump between spiral arms to provide them existing.

Spiral arms DO NOT ROTATE. They spread from the center to the edges. Their size is determined by the energy of the stream of particles ejected from the galactic emission center, and the presence of gas and dust that this stream of particles could heat up and make glow. And since the streams of particles move, although fast, at speeds up to the speed of light, it is hardly possible to notice their movement over a hundred years of observation.

The most remarkable thing is that the universe itself has painted for us in the sky a picture of fans of spiral thermal gradients, exactly corresponding to the fronts of propagation of particle fluxes from satellites of supermassive black holes, and even, as specially noted in this light picture, crosses exactly corresponding to the major and minor axes of the orbits of these satellites. This greatly simplifies their search and determination of their parameters.

Below is a single example. Several main spirals was restored on the image for galaxies IC2163+NGC2207.

Now we can move to the point where the were no any "dark matter" and re-start our investigations from scratch. Thank You.
