Like so much of the rest of the universe, its true nature remains a mystery.

Just recently, scientists were baffled by a diffuse galaxy that appeared to be lacking dark matter. It can take several forms, from weakly interacting particles to high-energy randomly moving particles created in the wake of the Big Bang.ĭark matter is still not well understood by scientists.

As they observe parts of the early universe, they could teach us more about these new particles and the organization they bring to the universe.In a new article found here, as reported by BGR, the pair say they were able to demonstrate the effect using a "simple simulations of a toy model comprising point-like satellites and an infinite domain wall." The new theory is notable because it explains the satellite disk problem without doing away with dark matter.ĭark matter is a nonluminous material that accounts for approximately 85 percent of the matter in the universe. That’s where space instruments like the James Webb telescope come into play. If we’re going to prove that there are invisible walls in space, we’re going to need to prove symmetrons exist. Of course, this is just a proof of concept. This could explain the differences that some larger galaxies have in the smaller galaxies that orbit them. The researchers also say there is a 50/50 chance that different regions will adopt different values for its symmetrons. Instead of the galaxies orbiting in a messy pattern, as the ΛCDM model suggests it should. Astronomers call these walls “domain walls” and they are what hold the galaxies in their refined orbits. Unlike past studies into the issue, this new research suggests that hypothetical particles called symmetrons could generate invisible walls in space. As such, it’s been an important part of these kinds of studies. Dark matter makes up most of the mass in the universe and has proven to be one of the universe’s biggest mysteries. The researchers posit that their research points towards a first potential “new physics” explanation that doesn’t do away with dark matter completely. A new physics explanation The star cluster NGC 1805 as imaged by the Hubble Space Telescope. The study is currently available via the preprint server arXiv. However, this new study from researchers at the University of Nottingham presents a different type of explanation for these invisible walls in space. Over the years, scientists have proposed many possible explanations to solve the “satellite disk problem.” Astronomers have also observed them in neighboring galaxies, too. These “satellites” as astronomers often refer to them, can be found in synced-up orbits throughout our own galaxy. Almost as if there is some invisible wall in space that the galaxies arrange along. These planes, or disks, look similar to the rings of Saturn. However, most small galaxies orbiting larger galaxies are arranged in thin flat planes. However, there’s been one perplexing challenge to this model, and sometimes it just doesn’t add up.Īccording to that model, small galaxies should be distributed in messy orbits around larger galaxies. The Lambda cold dark matter (ΛCDM) model is the current standard model we use to explain cosmology.
