The universe is a diverse and complicated complex complex complex of unknowns. To date, astrophysicists'' observations about the cosmos'' mapping suggest that small galaxies may be distributed around their host galaxies in a random order.
According to a Vice report on Tuesday, new data shows that these smaller galaxies form thin disks around their hosts. This is a snag, as it goes against what previous physics rules.
A new type of astrophysics
Two scientists from the University of Nottingham have proposed an interesting concept. They believe that smaller galaxies might be adapting to invisible walls created by a new class of particles called symmetrons.
If this turns out to be true, it might rewrite the laws of astrophysics by introducing a new type of physics.
The current standard theory, called the Lambda cold dark matter (Lambda-CDM), requires only three key elements to exist in the universe: the cosmological constant, cold dark matter, and the conventional matter we are daily. This means that smaller galaxies would be subjected to the gravitational pull of larger host galaxies and therefore travel in chaotic orbits, a factor that has not been verified thus far.
The researchers have developed a theory that would explain the unusual orbits of smaller galaxies that concern a dangerous fifth force.
The creation of invisible walls
This never-before-witnessed force might be responsible for the arrangement of galaxies into disk shapes, whileparticles known as symmetrons might be using this same space to create domain walls and types of invisible walls in space.
Because we have dark matter and dark energy, we suspect we would need to include new particles to our standard model to account for those things, according to aneesh Naik, a research fellow at the University of Nottingham, and the lead author of the study.
Is Naik''s claim true? Before it can be considered conclusive, there must be some research done, but it opens the way for some interesting arguments.
The yet-to-be-peer-reviewed study has been published in Cornell University''s database.
Under theCDM paradigm, the observed "planes of satellites" around the Milky Way and other nearby galaxies are notoriously difficult to understand. Here, we propose an alternative solution: domain walls that have been studied in scientific experiments because of the matter''s coupling, which can lead to a subset of satellites with orbits limited to the domain wall plane. We present this effect using simple experiments of a point-like satellite and an infinite domain wall, and we investigate the feasibility of various planarity metrics
