The universe is a diverse & complex entity, full of unknowns. So far, astrophysicists’ observations of the mapping of the universe indicate that small galaxies can be distributed around their host galaxies in a random order.
However, new data reveals that these smaller galaxies form thin disks around their hosts, according to a Vice report published Tuesday. Needless to say, this is confusing because it goes against what previous physical models dictate.
A new type of astrophysics
To make sense of this new information, two researchers from the University of Nottingham came up with an interesting theory. They speculate that smaller galaxies could adapting invisible “walls” created by a new class of particles called symmetries.
If true, it could rewrite the laws of astrophysics by introducing a new type of physics.
The current standard theory, known as Lambda cold dark matter (Lambda CDM), leaves-space for only 3 important elements that exist in the universe: the cosmological constant, cold dark matter, and the ordinary matter that we privy every day. This means that the smaller galaxies will be subjected to the gravity of the larger host galaxies and therefore travel in chaotic orbits, a factor that has not been proven by research to date.
Now, researchers have devised a theory that could explain the unusual orbits of smaller galaxies in relation to the elusive fifth force.
The creation of invisible walls
This unprecedented force could be responsible for aligning galaxies into disk shapes, while particles called symmetrons could use this very same space to create “domain walls”, invisible walls in the space.
“We knew we needed new particles because we had dark matter & dark energy and so we thought we would have to add new particles to our standard model to account for these. “, said Aneesh Naik, a researcher at the University of Nottingham and lead author of the study told Vice.
The study has been published in Cornell University’s database.
