Why is space filled with invisible walls?

Why is space filled with invisible walls?

Scientists’ best current theories regarding the organization of space are that small galaxies should be scattered around their host galaxies in seemingly random orbits. But according to a Vice report, space observations have found that these smaller galaxies organize themselves into disks around their hosts similar to Saturn’s rings. This clearly represents a perplexing gap between knowledge and theory.

Now researchers are trying to narrow the gap by suggesting that smaller galaxies might fit in with invisible walls created by a new class of particles called symmetrons, a startling proposal that could rewrite the laws of astrophysics.

The unified theory known as the Lambda-CDM model indicates that space is made up of three main components: the cosmological constant (the parameter that Einstein added to explain his equations of general relativity), and theoretical cold dark matter particles that move slowly and do not emit radiation. , and finally the traditional material we deal with on a daily basis.

This theory suggests that the gravity of large host galaxies should capture smaller galaxies and force them into chaotic orbits, something that has not been reflected in real-world observations. Now two researchers from the University of Nottingham have come up with a possible explanation in a new study.

The researchers suggest the possibility of a fifth force organizing galaxies in space into disc-like shapes, taking into account the presence of dark matter, the mysterious substance that appears to make up the vast majority of the mass of space. According to their theory, proposed particles known as symmetries (which researchers have used to explain gaps in space understanding) might generate this force to form a domain wall or boundary in space.

“We know we need new particles due to the presence of dark matter and dark energy, so we think we need to add new particles to our standard model in order to explain these things,” Inch Naik, a research fellow at the University of Nottingham who led the study, told Vice.

“This is the framework in which people study theories like symmetries, which are new candidate particles for dark matter and energy,” he continued. These particles may exist in groups with different polar states, forming invisible walls between them. These walls, in turn, may induce smaller galaxies to form disks around much larger host galaxies.

But there are many questions waiting to be answered, and Naik and his colleague, University of Nottingham physicist Claire Borage, still have a lot of work to do to strengthen the theory.
