Was thinking about "dark matter" when I had this idea: Not only is it invisible, and passes through normal matter without any effects but gravity, it is also evenly distributed in space. This means - it's own gravity does not affect it. Because if it did, it would form stars and galaxies like the normal matter does (the mainstream tells us these are the result of gravity...).
So there would be "dark stars" and "dark galaxies"... But wait - these could not form, the dark matter would need - "dark matter 2", to account for the missing mass. Because just adding more mass in form of dark stars and galaxies does not solve the problem - galaxies do not form without some "hidden mass" evenly distributed. So - dark matter is immune to it's own gravity.

So - dark matter is immune to gravity, else it would itself form dark galaxies - needing even another form of dark matter to explain for galactic formation... Look at the picture on wikipedia, it's evenly distributed:Dark matter plays a central role in state-of-the-art modeling of cosmic structure formation and galaxy formation and evolution
Why? Does it not have gravity?... Is there not enough of it? It's 90% of the mass...This artist’s impression shows the expected distribution of dark matter in the Milky Way galaxy as a blue halo of material surrounding the galaxy
