The mystery of a tiny galaxy with no dark matter is solved

The dark matter can form the "cosmic vampire", a giant but the invisible cloud that can steal stars from the other galaxies. The only way how dark matter reacts is by gravity. But the fact is that dark matter formations like galaxies matter has a similar gravity effect with the regular galaxies, and that means they could have a very big role in the life of the universe.

The reason why some small galaxies are smaller and contain less dark matter than they should is simple. Another galaxy can pull the stars away from the galaxy, but there is one exciting thing. The galaxy can meet the "cosmic vampire". Those giant formations of dark matter, which is acting like a regular galaxy. Also, dark matter formations have a gravity effect, and that thing can cause very big catastrophes.

The dark matter clouds or invisible galaxies can make a similar effect, what regular galaxies make when they are impacting. Those giant clouds can form around the black hole. One interesting thing is that even the dark matter doesn't interact otherwise, the gravitational interaction causes that theoretically, dark matter can form the black hole or supermassive black holes. Those dark matter clouds are invisible galaxies.

The galaxy, where is less dark matter than should has caused the reason for changing the galaxy forming theories. But now astronomers can be calm because the larger galaxy has been lost its dark matter. After all, the bigger and heavier galaxy pulls the dark matter and part of the stars of that small galaxy. The fact is that the dark matter is interacting with gravity and the large galaxy can pull the dark matter away from the smaller galaxies.

And that thing causes a very interesting idea, that the dark matter can form very large clouds or galaxies that are invisible because they are forming by the dark matter. Those dark matter formations are acting like normal galaxies, and they can also steal stars from other galaxies. The galaxy is acting like the "cosmic vampire". Ir can steal stars and other things like dark matter from galaxies.
