Scientists discover the smallest mass of dark matter


Dark matter can form small and cold blocks. Scientists have found the smallest to date, and it turns out that dark matter forms smaller blocks than scientists thought, which confirms the basic prediction about the mysterious substance, because this substance is the invisible things that are said to constitute about 27% of the total The mass in the universe, and although researchers cannot directly observe dark matter because it does not emit light or energy, they believe that it dominates all of outer space and even Earth.

According to the American “space” website, the widely accepted theory of “cold dark matter” explains that all galaxies are formed within clouds of dark matter, which consist of slow-moving or “cold” molecules, and the “cold” dark matter molecules form Structures or “blocks” can be “small” as the size of a plane.

A recent study, which used a new observational technique with NASA’s Hubble Space Telescope, provided evidence of the theory of “cold dark matter” and illustrated how mysterious objects make smaller blocks than scientists previously believed.

“We’ve had a strong observational test of the cold dark matter model,” said Tomaso Trio, a professor in the Department of Astronomy and Astrophysics at the University of California, Los Angeles, and a member of the team.

Researchers use the effects of gravity on nearby stars and galaxies to uncover dark matter and information about it, to indirectly monitor and study dark matter.

Researchers have found evidence of blocks of previously dark matter near large and medium-sized galaxies, but the groups in these new observations are the smallest of all, and because scientists have not seen such small groups of dark matter yet, some researchers have suggested before that There may be “warm” dark matter particles moving too quickly to form large structures, thus forming only smaller lumps.

But with these observations, it is clear that “cold” dark matter molecules can also form small masses, and as scientists continue to monitor and study dark matter, the mysterious substance becomes less mysterious.

This work reveals new information about dark matter and works to confirm the assumptions made about the material that constitutes such a huge percentage of our world.
