Researchers the world over have actually long thought that 70 percent of deep space is made up of dark energy, a compound that makes it possible for deep space to broaden at an ever-increasing rate. But in a brand-new research study, University of Copenhagen scientists checked a design which recommends that deep space’s growth is because of a dark compound with a sort of magnetic force. Should the design stand, it indicates that dark energy merely doesn’t exist, according to the UCPH teacher behind the research study.
Until now, scientists have actually thought that dark energy represented almost 70 percent of the ever-accelerating, broadening universe. For several years, this system has actually been connected with the so-called cosmological consistent, established by Einstein in 1917, that describes an unidentified repellant cosmic power.
But due to the fact that the cosmological consistent—called dark energy—cannot be determined straight, various scientists, consisting of Einstein, have actually questioned its presence—without having the ability to recommend a practical option.
Until now. In a brand-new research study by scientists at the University of Copenhagen, a design was checked that changes dark energy with a dark matter in the kind of magnetic forces.

“If what we discovered is accurate, it would upend our belief that what we thought made up 70 percent of the universe does not actually exist. We have removed dark energy from the equation and added in a few more properties for dark matter. This appears to have the same effect upon the universe’s expansion as dark energy,” discusses Steen Harle Hansen, an associate teacher at the Niels Bohr Institute’s DARK Cosmology Centre.
The universe broadens no in a different way without dark energy
The normal understanding of how deep space’s energy is dispersed is that it includes 5 percent typical matter, 25 percent dark matter and 70 percent dark energy.
In the UCPH scientists’ brand-new design, the 25 percent share of dark matter is accorded unique qualities that make the 70 percent of dark energy redundant.
“We don’t know much about dark matter other than that it is a heavy and slow particle. But then we wondered—what if dark matter had some quality that was analogous to magnetism in it? We know that as normal particles move around, they create magnetism. And, magnets attract or repel other magnets—so what if that’s what’s going on in the universe? That this constant expansion of dark matter is occurring thanks to some sort of magnetic force?” asks Steen Hansen.

Computer design tests dark matter with a kind of magnetic energy
Hansen’s concern acted as the structure for the brand-new computer system design, where scientists consisted of whatever that they understand about deep space—consisting of gravity, the speed of deep space’s growth and X, the unidentified force that broadens deep space.
“We developed a model that worked from the assumption that dark matter particles have a type of magnetic force and investigated what effect this force would have on the universe. It turns out that it would have exactly the same effect on the speed of the university’s expansion as we know from dark energy,” discusses Steen Hansen.
However, there stays much about this system that has yet to be comprehended by the scientists. And all of it requirements to be signed in much better designs that take more aspects into factor to consider. As Hansen puts it:
“Honestly, our discovery might simply be a coincidence. But if it isn’t, it is really unbelievable. It would alter our understanding of deep space’s structure and why it is broadening. As far as our present understanding, our concepts about dark matter with a kind of magnetic force and the concept about dark energy are similarly wild. Only more in-depth observations will figure out which of these designs is the more practical. So, it will be exceptionally amazing to retest our outcome.
