Dark matter might open to researchers.

Dark matter and hydrogen are interesting things when we think about the Voyager probe and its findings about the cosmic "hum" that cannot reach our solar system. And the giant hydrogen cloud called Eos that surrounds our solar system we can think that we might be close to finding the dark matter. 

Same way as Eos surrounds our solar system. Similar hydrogen atoms and ion clouds surround our galaxy Milky Way. And its company galaxies. The thing that makes those massive hydrogen and proton clouds hard to see is that they are so cold. We are in the warm area around the Sun, and radiation that comes from the sun covers that gas cloud from us.

The temperature of Eos is much lower than the temperature in our solar system. And when the sun sends radiation that radiation scatters from the dust that is all around the solar system. So the radiation that Eos reflects is so low energy level that scattering radiation and reflections from planets and asteroids covers that kind of low-temperature hydrogen cloud below it. 

There is the possibility that the weakly interacting massive particles, WIMPs are spinning particles that bind energy inside them. So spin turns the universe's base energy field, or Higgs field into kinetic energy. That means those things can simply bind energy into them. 

Can dark energy be some kind of Cherenkov radiation? It's possible. The hydrogen halos around solar systems and galaxies cause the particles to slow. When they enter those hydrogen halos. Those hydrogen halos are not very dense. So slowing is not very radical. The radiation burst that a particle sends when it transfers kinetic energy to that halo is not very strong. That explains some parts of the dark energy nature. Why does it affect only the large entireties?

Those ultimate cold hydrogen clouds can also cause a scattering effect that slows the speed of light. If that hydrogen cloud is removed that will increase the speed of light. If we think that the cosmic voids or bubbles in those hydrogen clouds can offer space where photon travels faster than in hydrogen clouds that can explain dark energy like this. 

When a photon or some other particle travels through those cosmic voids and enters back into those giant hydrogen clouds their speed slows. In that model, the particle must remove that energy. Or transfer that energy somewhere. That can be the energy field in those cosmic halos. So that means dark energy can be some kind of Cherenkov radiation. 

The same thing happens in the hydrogen halo that surrounds the galaxy and galaxy groups. So maybe one of the most interesting secrets of the dark matter hides in those hydrogen halos. Those hydrogen halos cause questions like, what is the temperature or energy minimum in the entire universe? Those halos that surround galaxies can be hotter than the energy minimum. But the question is, what kind of errors do those halos cause for measurements? In extremely accurate measurements every part of the system means something.
