The dark matter can form energy for some stars.

"Deep in the center of our galaxy, scientists believe a strange type of star may be quietly glowing—not from fusion like our Sun, but from the invisible fuel of dark matter."

These “dark dwarfs” could act like cosmic detectors, collecting heavy, elusive particles that heat them from the inside. If we find them—and especially if we spot one missing its lithium—it could finally point us toward what dark matter really is."

*******************************

If dark or black dwarfs really exist those things can reshape the end of our universe. Those things can form the extra energy that we call dark energy. The white dwarf can also turn into a black dwarf when its energy storage is over. The black dwarf can cause dark matter annihilation which can form energy in the universe. 

Dark (or black) dwarfs mean brown dwarfs, stars that have failed and used up their nuclear fuel. Those stars are a  theoretical group of brown dwarfs. The origin of those things is brown dwarfs, the mysterious medium between planets and stars. Those brown dwarfs can burn their fuel very fast and turn into dark dwarfs. Dark dwarfs have no internal fusion material. They are quite massive but cold objects. That means. They are heavy. If we compare them with planets. And that thing can make them the gravitational traps for dark matter. The gravitational center also pulls dark matter around it. If dark matter has the particle form and the weakly interacting massive particles, WIMPs are real, which causes a situation where those particles impact the star's core. 

And that thing can form when dark matter travels into those stars. That gravitation will accelerate the hypothetical dark matter particles, WIMPs, that cause annihilation-type reactions in the dark dwarf. That dark matter interaction can form the “dark light” or dark energy. If that dark energy density is high enough that thing makes it possible that the dark matter annihilation forms so much dark energy that it makes those dark dwarfs shine. In this hypothesis, dark matter annihilation is the source of dark energy. 

The dark dwarfs, stars that should not shine might tell us about the dark matter. There are stars near the center of the galaxy that get energy not from fusion, but the energy that those stars shine forms from dark matter interaction. Near the center of the Milky Way material and energy are denser than at the outer edge of the Milky Way. The giant black hole Sgr A* pulls material and energy into it. In the gravity field, dark matter interacts in a similar way to the visible material. Except that gravity is the only known interaction between visible and dark matter. That means dark matter follows a similar spiral trajectory to Sgr A* as visible material. But that thing is not the entire truth about that strange phenomenon. 

Gravity centers like planets and stars also pull dark matter around them. And that thing can explain why those dark dwarfs can form energy from dark matter. There is a possibility that fast-moving dark matter forms some kind of gravity effect in the star. And that gravitational effect can form whirls that create energy for the star. The other, but more interesting model could be that the antimatter would be particles. And when those small stars trap dark matter in them that dark matter cloud inside them the outgoing dark matter particles impact with those local particles. Those impacts can release energy. 

Maybe, that is the first time when dark matter forms so much dark energy that it can interact with visible material. Dark matter interaction can open the path to new energy sources. But that interaction where hypothetical dark matter particles impact each other can explain the dark energy. These types of stars are the first time that some objects can get their energy from dark matter. And that observation tells about things like dark matter interactions with material. 

When a star or planet’s formation starts there must be a gravitational point that pulls material into it. The dark matter can be that gravitational point as well as some visible particles. Dark matter can also form black holes. But if some star gets its energy from dark matter, that thing will be a new and interesting observation. The new model about stars and their material is that every object in the universe involves both dark and visible material. Because dark matter interacts through gravity, planets and stars also pull dark matter inside them. The position of dark matter is unknown. It can be inside the quarks, between quarks, or electrons, or between other subatomic particles.
