Dark and regular matter are not separate, which reveals the study because the cosmos finds a way for it to connect. But it is well known that dark matter is hard to pin down and figure out because it cannot be seen, even felt, or touched. Four universe models allow it to be factored in a cosmological sense as an intricate part.
New Study Begs To Differ
According to Science, there is some clue this invisible matter is there because there is gravity. How the interaction happens is still unknown and propose the answer is nonminimal coupling. Three cosmologists, Giovanni Gandolfi, Andrea Lapi, and Stefano Liberati, explained whether said is gravity wrong or are we just missing something crucial about dark matter's nature?
Cold, weakly interacting huge particles that experimental physicists worldwide have been seeking to detect for decades are one good suggestion for what dark matter might be.
Considering how this type of dark matter behaves in our models, there are a few problems. The cuspy halo problem is a large one, wherein the inferred density of dark matter in galaxies does not match what is known as N-body simulations concerning dark and regular matter, reported Sciencealert.

According to simulations, dark matter in low-matter galaxies is 'cuspy,' meaning it is most concentrated towards the cusp outside the galaxy to explain their current structure and movement. Though in dwarf galaxies, their dark matter is in the center.
Dark and Regular Matter
It's not the first study to solve the problem through a new tact that has been introduced. According to the researchers, if dark matter is not minimally coupled to gravity, it solves the cuspy problem and a related problem defined as the radial acceleration relation.
In the new paper, scientists write; They seek to make changes to the traditional cold dark matter framework so that it may accurately describe observable galaxy rotation curves while also faithfully reproducing the radial acceleration connection.
Introducing this coupling can help cold dark matter sustain its success on huge cosmic scales while enhancing its behavior in galactic systems.
The term nonminimal coupling is a misunderstanding. It means that dark matter is closely intertwined with the Einstein tensor, a curve in spacetime.
Put simply, and it's a novel sort of dark matter-gravitational interaction. Whether there is nonminimal coupling, dark matter uniquely behaves with spacetime to regular matter.
They call this nature of dark matter, not exotic fundamental physics. Nonminimal coupling can explain with known physics.
It's just a supposition, but it fits the observational evidence so far. Dark matter is still a tricky beast. More investigation is needed if the nonminimal coupling is a property of dark matter or merely another idea that propels us forward to find what's going on. The authors say that dark matters will be studied more.
Furthermore, more research will be conducted to investigate the intriguing ramifications of this suggested new dark matter trait.
They wouldn't be shocked if this nonminimal coupling turned out to be the answer to other Universe mysteries, according to Op science. Dark and regular matter, if their interaction via gravity or other means is discovered, will answer more questions or breed more answers.
