Dark matter is not necessarily a particle. It can be a quasiparticle or a soliton in the gravity field.

"Dark matter influences cosmic behavior through gravitational interactions, leading to phenomena like “dark stars,” which may explode similarly to supernovae.

In the WIMP (Weakly Interacting Massive Particle) model, the WIMP is the dark matter particle. The mystery is how those particles can be invisible. And then another mystery is: are all those particles similar, or are they some kind of quasiparticles? 

One thing that can help us to understand the dark matter's role is the energy flow. Energy flows always to a lower energy area. Galaxies are at higher energy levels than their environment. We can think that every single galaxy is on the table. And energy flows away from them. That makes it hard to see material that is between galaxies. If energy flows in a dark matter direction, we cannot see that thing without reflection. 

In some models, dark matter is a particle that spins very fast. That means radiation can travel past this object. In that model, a particle forms a standing wave that closes reflection in that quantum field which looks like the Earth's magnetic field. The other model is that this particle transforms radiation into a string that is hard to see. 

There are books written on dark matter. Cosmologists made lots of theories about this invisible and still dominant gravity effect. Some of those theories require that the Higgs field exists. The hole in Higgs field forms when some high-.energy beam with the same frequency as the Higgs field impacts the universe. 

Then that energy beam pushes the Higgs field away like water pushes air when a submarine's hull breaks. That interaction would be possible if there were other universes. The high-energy beam pushes the theoretical Higgs field away its way. Then that fallen channel moves Higgs field back to that channel.

Even if researchers cannot see dark matter straight. They can see the gravitational shadow of that thing. 

At the beginning of the dark matter research, researchers thought that dark matter was evenly distributed. But then they found the galaxy there was no dark matter. That galaxy proved that dark matter can form similar structures as regular matter. 

The term: dark matter stars means an object that is too light being a black hole, but invisible. Those things may be hypothetical planet-mass-back holes. The key element in this model is this: if the planet's nucleus is colder than 3 kelvin radiation the outside energy pushes the planet into a black hole. And in some models, small-mass black holes are the thing called dark matter. 

The term dark matter means the gravity effect whose origin is unknown. This means that dark matter can be real particles, quasiparticles, or maybe dark matter is some kind of channel through the Higgs field. It's also possible that dark matter is a material. Whose energy level is lower than three-kelvin radiation. 

When we think about dark matter's existence, we must understand that also the quasiparticles or gravitational solitons can make the gravitational effect that origin is unknown. Or it's invisible to us. There are two types of dark matter in the original dark matter model.  But there could be many more dark matter types than those two types. 

1) Cold dark matter.

2) Hot dark matter.

That means: there could be many types of material things in the universe that can form the dark gravitational effect. In some models, the Bose-Einstein condensate or atoms with minimum energy levels can transfer similar effects on protons and neutrons. In Bose-Einstein condensate the atom's size is bigger than in the normal case. Maybe there is a model that proton's quantum field can expand. 

In this model the proton's and neutron's expanded quantum field allows photons can push quarks away from their route. In that model, dark matter exists in the intergalactic space. 

Outside the galaxies, quantum fields are very weak if we compare them with quantum fields in galaxies. They cannot push protons the same way as quantum fields can push them inside galaxies. And maybe that thing allows the photons to travel through the atom's nucleus and protons and neutrons. 

In the quasiparticle model, there is an electron hole. That is so deep that multiple electrons can start to obit it. Or maybe some missing quark makes a similar hole or pothole as an electron leaves in an electron orbiter. But there are no observations or evidence about gluon- or quark holes.  In the quasiparticle hypothesis, the dark matter is like super-exciton. The black hole is like an electron-hole. But it makes a hole in a different wavelength field than an electron. The quasiparticles can form a group that interacts like a planet. The mystery of dark matter is not solved. That means we will return to that topic quite soon.
