One of the biggest challenges to our traditional understanding of the universe is the so-called “satellite disk problem”. Scientists are mainly confused because smaller galaxies orbit larger galaxies in thin, flat planes, rather than in the more turbulent orbits one would expect with the lambda cold dark matter model (ΛCDM) – the “incredibly successful model” that determines how we observe space.
To get around this problem, scientists now assume that particles called “symmetries” create invisible walls in space that astronomers call “field walls.” This in turn creates what University of Nottingham astronomers Anish Naik and Claire Berraj have described as the potential “fifth force” in physics.

in one New article found hereAs I mentioned before BGR, the two said they were able to demonstrate the effect with “a simple simulation of a game model including point satellites and an infinite sphere wall.” The new theory is noteworthy because it explains the satellite’s disk problem without removing dark matter.
Dark matter is non-luminous matter that makes up about 85% of the matter in the universe. It can take many forms, from weakly interacting particles to randomly moving high-energy particles formed as a result of the Big Bang.
Dark matter is still poorly understood by scientists. Recently, scientists were amazed at a diffuse galaxy that seemed to lack dark matter. Like much in the rest of the universe, its true nature remains a mystery.
In the meantime, scientists will continue to explore the potential of “Symmetrons” with more detailed simulations.
