Why dark matter can not collapse into a black hole under it's own weight?

Bloodthunder said:Because dark matter interacts very little with ordinary matter. Black holes are ordinary matter, so...
Pengwuino said:No. Black holes are purely gravitational phenomena. In fact, the ONLY known interaction dark matter is capable of being a part of is the gravitational interaction and would collapse into a black hole just like any other forms of matter.
Bloodthunder said:Okay, might have been a little wrong there. However, you seem to be talking about dark matter falling into black holes. What about the case for dark matter itself? Is dense dark matter "masses" capable of gravitational collapse?
Dark matter is a type of matter that does not emit or absorb light, making it difficult to detect. It is believed to make up about 85% of the total matter in the universe. Unlike regular matter, dark matter does not interact with electromagnetic radiation, which is why it cannot collapse into a blackhole.
The main reason why dark matter cannot collapse into a blackhole is its lack of interaction with electromagnetic radiation. This means that there is no way for dark matter particles to lose energy and collapse into a blackhole like regular matter does. Additionally, dark matter particles do not interact with each other, making it impossible for them to clump together and form a blackhole.
Theoretically, if dark matter were to interact with regular matter, it could potentially form a blackhole. However, current research and observations suggest that dark matter does not interact with regular matter in a significant way. Therefore, it is unlikely that dark matter could form a blackhole through interactions with regular matter.
Dark matter is thought to play a crucial role in the formation and evolution of galaxies. Its gravitational pull helps to hold galaxies together and prevent them from flying apart. Without dark matter, galaxies would not have enough mass to maintain their shape and structure. However, dark matter itself cannot form a blackhole due to its lack of interaction with electromagnetic radiation.
Although we cannot directly observe dark matter, there is strong evidence that supports the idea that it cannot collapse into a blackhole. Observations of galaxy clusters, gravitational lensing, and the rotation curves of galaxies all support the existence of dark matter and its inability to form blackholes. Furthermore, simulations and models of the universe also support this concept.
