How much energy does it need to get rid of in order to collapse to one of these celestial bodies?Orodruin said:No. Dark matter has no way of getting rid of enough energy to collapse that far.
The problem is that DM cannot lose energy. For instance, think two masses (baryonic) that are colliding with each other. If they make an inelastic collision then they will lose some energy which means that kinetic energy of the particles transforms into heat or etc. Now, they are moving as one piece.However if DM is made from particles, according to the observations, they cannot lose their energy via heat. This implies that they cannot combine with each other to create bigger objects. Because this process needs an energy transformation from kinetic energy to heat, which DM particles are not capable of.MathematicalPhysicist said:How much energy does it need to get rid of in order to collapse to one of these celestial bodies?
Contrary to your signature, DM don't connect... :-)Arman777 said:However if DM is made from particles, according to the observations, they cannot their energy via heat.

Dark matter is a type of matter that does not emit or absorb light, making it invisible to telescopes and other instruments used to study the universe. It is believed to make up about 85% of the total matter in the universe.
Currently, there is no direct evidence that planets or stars can be composed entirely of dark matter. However, scientists have observed the effects of dark matter on the rotation and movement of galaxies, leading them to theorize that it may also play a role in the formation and composition of celestial bodies.
As dark matter does not interact with light, it is extremely difficult to detect and study. However, scientists are using a variety of methods and instruments, such as gravitational lensing and particle detectors, to try and gather more information about this elusive substance.
Currently, there are no confirmed observations of planets or stars composed entirely of dark matter. However, scientists continue to search for evidence and study the effects of dark matter on celestial bodies.
The discovery of planets or stars composed entirely of dark matter would greatly impact our understanding of the universe and its formation. It could also provide valuable insights into the nature of dark matter and its role in shaping the structure of the universe.
