The absence of "dark matter" from galaxies baffles scientists

19 recently discovered small galaxies share one characteristic, which is free of dark matter

A recent discovery has puzzled scientists, finding that 19 recently discovered small galaxies share one characteristic, which is free of "dark matter."

Scientists believe that dark matter , "invisible", is responsible for the cohesion of galaxies, and is one of the foundations of the interpretations on which researchers explain how galaxies form.

According to the observatory of the future, which specializes in scientific news, astronomers have two options, where they must acknowledge the error of modern discovery, or try to reconcile it with their understanding of the universe.

In their research, published in the journal Nature Astronomy, scientists found that new galaxies rotate at a faster pace than galaxies equal in size, indicating their lack of dark matter.

According to scientific knowledge, a galaxy containing dark matter rotates faster than it would be if it was subject to the gravity of the visible matter.

Among the explanations suggested by scientists, some galaxies lack dark matter due to the gravity of other nearby galaxies, but this explanation collides with the fact that some newly discovered galaxies are isolated and not near by others, according to the scientific site Life Science.
