Spread galaxies A new study has found that millions of light-years away may be the largest rotating object in the universe.
Celestial bodies often rotate, from planets to Stars to galaxies. However, giant galaxy clusters often rotate very slowly, that is, at all, and many researchers believe that the rotation at cosmic scales may end here, according to study co-author Noam Libeskind, from the Leibniz Institute for Physics. Cosmologist in Potsdam. Germany, Space. com.
But in new research, Libeskind and his colleagues found that cosmic fibers, or giant tubes, appear to be bulging out of galaxies. “There are structures that are so massive that entire galaxies are just grains of dust,” Libeskind said. “These massive filaments are much larger than clusters.”

Previous research suggested that after the birth of the universe great explosion About 13.8 billion years ago, most of the gas, which makes up most of the known matter in the universe, collapsed into giant plates. Then these leaves became broken strings vast cosmic network.
Using data from the Sloan Digital Sky Survey, the scientists examined more than 17,000 filaments and analyzed the speed at which the galaxies that make up these giant tubes move in each tendril. The researchers found that the way these galaxies were spinning showed that they were each orbiting around the filament’s central axis.
The fastest discoverers that could orbit galaxies around the hollow centers of these tendrils were about 223,700 mph (360,000 kph). Scientists note that they do not claim that all fibers are in Universe It’s spinning, but those threads seem to be there.
The big question is, “Why are they roaming around?” Libeskind said. The Big Bang would not have given the universe a fundamental rotation. Whatever spins those filaments must have originated later in history when the structures formed, he said.
One possible explanation for this rotation is that the resulting shear forces may have rotated the material as the strong gravitational fields of these filaments attract gas, dust, and other materials to crumble together. “We are not currently sure what might be causing a torque of this magnitude,” Libeskind said.
Scientists are now trying to understand the origins of spun filaments through computer simulations of how matter behaves in the largest cosmic sale. researcher hinge your conclusions 14. Juni Online in Naturastronomy.
