Invisible walls in space may explain a problem that has baffled scientists

One of the greatest challenges to our traditional understanding of the universe is the so-called “satellite disk problem.” Essentially, scientists are confused that smaller galaxies orbit larger galaxies in thin, flat planes rather than the chaotic orbits that would be expected under the lambda cold dark matter model (ΛCDM) – the “very successful model” that determines how we observe space.

In order to circumvent this problem, scientists now assume that particles called “symmetries” generate invisible walls in space, which astronomers call “field walls”. This in turn creates what astronomers Aneesh Naik and Clare Burrage of the University of Nottingham describe as a potential “fifth force” in physics.

In New Paper Found Here, as mentioned before BGR, the pair said they were able to demonstrate the effect using “a simple simulation of a game model that includes point satellites and an infinite field wall.” The new theory is remarkable because it explains the problem of the satellite disk without eliminating 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 created as a result of the Big Bang.

Dark matter is still poorly understood by scientists. Recently, scientists were baffled by a diffuse galaxy that appeared to lack dark matter. Like much of the rest of the universe, its true nature remains a mystery.

In the meantime, scientists will continue to investigate the potential of “symmetry” with more detailed simulations.
