Space is a mysterious place and many people around the world are working to uncover it layer by layer. Still, some puzzling events up there remain unexplained. Scientists now believe there may be invisible walls in space. However, these walls are not comparable to the walls of a room. Instead, they are more like barriers. Scientists believe these walls may have been created by a “fifth force” mediated by a hypothetical new particle called the Symmetron. And the existence of this force could help understand a fascinating part of space that has long frustrated astronomers.
We currently use the lambda model of cold dark matter as the standard model to understand our universe. This model states that small galaxies should be distributed in chaotic orbits around larger galaxies. In reality, many small galaxies orbiting larger galaxies are arranged in thin flat planes (discs) resembling Saturn’s rings. This arrangement seems like there are invisible walls in space that make them arrange themselves despite the lambda model.
In other words, these small “satellite” galaxies are caught by the gravitational pull of larger galaxies and are arranged in thin flat planes, while the model suggests they should be scattered in chaotic orbits around their host galaxies. These small galaxies have been seen in synchronized orbits in our own galaxy, the Milky Way, and in neighboring galaxies as well. Scientists have proposed several explanations for this “satellite disc problem”.
However, the new study by researchers at the University of Nottingham has offered a new explanation. It is available via the preprint server arXiv. They call it “the first potential explanation of the ‘new physics.’ It suggests that symmetrons could create invisible walls in space.
However, the study is only a proof of concept. To prove that there are invisible walls in space, scientists must first prove that symmetrons exist. This will require the service of NASA’s James Webb Space Telescope, which should be ready for scientific observation this summer.
