New candidate particle for Dark Matter: Hexaquark D-Star, Dark Matter is a mysterious substance that constitutes approximately a quarter of the Universe. Dark matter is the mysterious substance that constitutes approximately a quarter of the universe.
There is strong indirect evidence of its existence from cosmic primary radiation measurements, discrepancies in the radial dependence of the galactic rotation curves and gravitational lenses. Despite its apparent role in the universe, the physical origin of dark matter remains unknown.
Scientists suspect that it is made up of invisible particles that do not reflect or absorb light, but are capable of controlling gravity. Two theoretical physicists from the University of York, United Kingdom, have a new candidate.

The mass structure of the universe is simulated with dark matter fibers in blue and places of formation of the galaxy in yellow. The hexaquar is composed of six quarks, which are basic particles that generally combine into three to form protons and neutrons. Importantly, six quarks in a D * (2380) result from a boson particle.
Which means that when there are multiple D * (2380) they can be combined in very different ways for protons and neutrons. Dr. from the University of York MIKL Bashkonov and Professor Daniel Vats suggest that in the conditions immediately following the Big Bang and several hexquak D * (2380) could be grouped as the universe cooled and expanded to constitute the fifth state of The matter.
Condensate Hua Bose-Einstein. The origin of Dark Matter in the Universe is one of the most important questions in science and one that, so far, is an empty question,” said Professor Watts. “Our first calculations indicate that Hexaquark condensate (2380) is a new viable phenomenon for dark matter.
This new result is particularly exciting because it does not require any new concept for physics. The next step in establishing this new Dark Matter Candidate will be to better understand D * (2380) Hexquax’s conversations about when they are attracted and when they repeat themselves, said Dr. Bashkanov said.
We are leading new measurements to make hexaquarks d * (2380) within an atomic nucleus and see if their properties differ when they are in free space. The team article was published in Physics G: Nuclear and Particle Physics Journal.
How Dark Matter interacts with Ordinary Matter. New measurements of a group of colliding galaxies suggest that mysterious matter is only probable and normal matter only through gravity. Many of the conclusions of this contrast were drawn by scientists from observations of three years ago.
About 27 percent of the universe is dark matter, but scientists still know very little about what it really is. This dark matter does not emit or reflect light, making it difficult to study. Its gravity can bend the path of light known as gravitational lenses, which has helped astronomers detect that something is out.
A team of researchers used the Hubble telescope 3 years ago to observe colliding galaxies in the Abell 3827 cluster located approximately 1.3 billion light-years from Earth. The visible matter in the collision appeared to be the dark matter of galaxies, which scientists say could indicate that, in addition to gravity, other substances could also sense dark matter.
The image shows four central galaxies in cluster Abell 3827 with ultraviolet light from Hubble imaging (blue) and infrared light from ALMA observations (red). At these wavelengths, scientists can determine the extent to which a galaxy is distorted behind the cluster by the gravity of normal, dark matter. [Source tips16.com]
He revised the observations for a new study at the Atacama Large Millimeter / Submillimeter Array (ALMA) in Chile. It is a power telescope capable of detecting details of Hubble observations. The data detected previously undescribed dark matter locations around the collision.
“We got a higher resolution view of a distant galaxy using ALMA than the Hubble Space Telescope,” said Lelaya Williams, a researcher at the University of Minnesota and a co-author of the paper. “Compared to our previous comments, Dark Matter’s exact position is clear.”
This indicates that the dark matter of most galaxies remained with them during the collision. Dark matter feels the effects of gravity exclusively or only weakly interacts through other forces. Alternatively, the group can move toward Earth, in which case we wouldn’t expect to see any lateral shift in the dark case, the scientists said in the statement.
Assuming the truth that dark matter will move to the front or back of the group, making it difficult to detect offsets. Astronomers around the world are searching the sky for clues to the nature of dark matter. Many hypotheses have evolved to explain matter as scientists use computer models to figure out what to look for.
The various properties of Dark Matter leave the telltale sign, Andrew Robertson, a researcher at Durham University in the United Kingdom and co-author of this work. A particularly interesting test is that the Dark Matter interaction will make the Dark Matter gripper more spherical, “Robertson”.
