“Cloud and rain model”
The real structure of the Universe

Whereas clouds are persistently there every day,
thank nature,
 rain doesn’t always fall.

            Universe has nucleus at center. It is located around behind Ursa Major & Leo constellation. Space of Universe contents of “Dark matter”. It is like atmospher of our planet. So we just call it atmospher of space or atmospher of cosmos.
      At cosmos, bundles of fogs of concentrated dark matter construct stars and their solar system. The neighbor stars construct small or micro galaxies. The micro galaxies will continue developing themselves to be bigger and bigger to become galaxies.
      Besides being the source of matters for stars construction and galaxies growth, dark matter dynamics in mighty space also functions as cosmic atmosphere that drag galaxies to get away from “Universe’s nucleus”. This event causes galaxies spread and recede from each others in cosmos. It is commonly observed as cosmos object with relative small red shift.   
      Just like clouds in our sky, galaxies will get condensation. Getting ageing, the stars will die and the black holes in galaxies will grow bigger. In cosmos, the event or the result of galaxies condensation is observed as quasars. Then, when a galaxy or a quasar gets too dense, it will fall down, back toward Universe nucleus due to gravity of “Universe’s nucleus” turning stronger than dragging force of “cosmic atmosphere (Dark matters)”. Those all events happen in cycles continuously.
