Researchers at the Harvard and Smithsonian Center for Astrophysics have run one of the most advanced simulations of dark matter ever achieved, and believe they have produced an image of elusive, 'invisible' matter. </p><div><p>Despite making up an estimated 85 percent of all cases in the universe, Dark Matter has long dodged the scientific community. This forms a central part of our most advanced theories about the universe, and is therefore important to our understanding of… well, pretty much everything.
However, it is impossible to photograph because it does not interact with light; We can only detect it through its gravitational effect on light (we cannot see the wind but it can break the leaves and branches of trees to compare).

Breakthrough in dark matter mystery as neutral hydrogen from other galaxies first revealed
Scientists have observed the perceived effect of dark matter on a galactic scale, as it forms ‘halos’ around galaxy clusters. According to recent simulations conducted by researchers at Harvard, under the leadership of Ji Wang, these dark mantle halogues all occur on a large scale, ranging from galactic to planetary.
During five years of research, development, and testing to produce simulations, the team assumed that dark matter contains about 100 times larger mass than a proton and that it interacts with weak particles (WIMPs), According to one the leading theories about Dark Matter.

Scientists believe that new theories may eventually shed light on DARK MATTER
Unlike previous Dark Matter simulations, however, their simulation was typically of higher resolution, operating at some 30 orders of magnitude. They found that these hollows had a similar structure, dense toward the center and rapidly spreading towards the edge, regardless of scale.
Small, planetary-scale exposures are too small to detect through their effect on the surrounding light, but they can confirm another theory about dark matter; It emits gamma radiation when its particles collide with each other.
“These small aura can only be studied by simulating the evolution of the universe in a large supercomputer,” Wang said.

Mystery of the Milky Way’s peculiar luster rejected the major theory
If confirmed, it will once again unravel the mystery about the gamma ray ‘glow’ in the center of our galaxy. In fact, dark matter is believed to collide together in deep space to form the seeds of galactic groups.
“This would confirm the envisaged nature of dark matter, which cannot be completely dark,” Said Simon White, co-author of the Max Planck Institute of Astrophysics.
“Our research sheds light on these tiny aura as we want to know more about what dark matter is and what role it plays in the evolution of the universe.”
Scientists are constantly developing new models to try and understand this mysterious case, but this latest simulation could try to direct future research and give a clue to the path of humanity.
