tendrils galaxies A new study has found that hundreds of millions of light-years away could be the largest rotating object in the universe.
Celestial bodies often rotate, from planets to stars to galaxies. However, massive galaxy clusters often rotate very slowly, and this is at all, and many researchers believe that the rotation on cosmic scales could end here, according to study co-author Noam Libeskind, a cosmologist at the Leibniz Institute of Physics in Potsdam, Germany, in Space. com.
But in the new research, Libeskind and his colleagues found that cosmic filaments, or giant tubes, appear to be emerging from galaxies. “There are structures so massive that entire galaxies are just grains of dust,” Libeskind said. “These massive filaments are much larger than clusters.”
Previous research indicated that after the birth of the universe the great explosion About 13.8 billion years ago, much of the gas, which makes up most of the known matter in the universe, collapsed into giant slabs. Then these leaves shattered to form strings leaked cosmic web.
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 tendrils. The researchers found that the way these galaxies moved indicated that they were orbiting around the central axis of each filament.
The fastest explorers to orbit galaxies around the hollow centers of these tendrils were around 223,700 mph (360,000 kph). Scientists note that they do not claim that all threads are present Universe It spins, but it looks like those leads are in there.
The big question is, “Why are they spinning?” Libeskind said. The Big Bang would not have given the universe a primordial spin. Whatever makes those threads spin, he said, must have arisen later in history when the structures formed.
One possible explanation for this rotation is that the resulting shear forces may have spinned the material because the strong gravitational fields of these filaments attract gas, dust, and other materials to crumble together. “We’re not currently sure what would cause torque of this magnitude,” Libeskind said.
Scientists are now trying to understand the origin of spun threads through computer simulations of how matter behaves in the cosmic biggest sales. researcher detailed Your results 14. Juni Online at Naturastronomie.
