Researchers know that dark energy is not magnetic in the traditional sense. In this case, a north pole repels another north pole while attracting a south pole. This particular type of magnetism is related to the force that always repels, under this action, it expands the universe instead of maintaining its limits.
"If what we find is accurate, it will subvert our belief that what we think makes up 70% of the universe does not actually exist. We remove dark energy from the equation and add more properties to dark matter This seems to have the same effect on the expansion of the universe as dark energy.
The general understanding of the energy distribution of the universe is that it is composed of 5% normal matter, 25% dark matter and 70% dark energy.
In the new model, 25% of dark matter has a special quality, making 70% of dark energy redundant.
"Except that dark matter is a heavy and slow particle, we don't know much about dark matter. But then we want to know-does dark matter have a quality similar to magnetism? We know that as normal particles move, they produce magnetism. Moreover, magnets attract or repel other magnets-so what if this is what happens in the universe? Does the constant expansion of dark matter occur due to some kind of magnetic force?" Hansen asked.
Hansen’s problem is the basis of the new computer model. Researchers include everything they know about the universe, including gravity, the speed at which the universe expands, and X (the unknown force that causes the universe to expand).
"We developed a model based on the assumption that dark matter particles have a certain magnetic force, and studied what effect this force will have on the universe. It turns out that this will have exactly the same effect on the expansion rate of universities, just as we learned from dark energy As I learned in the game.” Hansen explained.
However, this mechanism is still unknown to many researchers. Moreover, all of these need to be checked in a better model that takes into account more factors.
"Frankly, our discovery may just be a coincidence," Hansen said. "But if it is not so, it is indeed incredible. This will change our understanding of the composition of the universe and why it expands. As far as our current knowledge is concerned, our thoughts about dark matter with a certain magnetic force and about dark energy The idea is equally absurd. Only more detailed observations can determine which of these models is more realistic. Therefore, it will be very exciting to retest our results."
