tendrils of galaxy The largest rotating object in the universe could be hundreds of millions of light-years away, a new study finds.
Celestial bodies often rotate, from one planet to another star to the galaxy. However, giant galaxy clusters often rotate very slowly, if at all, and so many researchers think that this could be the end of the spin on a cosmic scale, said study co-author Noam Libeskind, a cosmologist at the Leibniz Institute for Astrophysics. Potsdam in Germany Weltraum.com.
But in the new study, Libeskind and his colleagues found that the cosmic filaments, or giant tubes made of galaxies, appear to be spinning. “There are structures so massive that the entire galaxy is just a grain of dust,” Libeskind said. These large filaments are much larger than the cluster.

Previous research suggested that after the universe was born in Big bang 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. These sheets then break to form filament from the big one cosmic web.
Using data from the Sloan Digital Sky Survey, scientists examined more than 17,000 filaments and analyzed the speed at which the galaxies that make up this giant tube move within each tendril. The researchers found that the way these galaxies move indicates that they revolve around the central axis of each filament.
The fastest galaxy the researchers saw circling around the hollow center of these tendrils was about 360,000 km/h. The scientists note that they are not suggesting that every single filament is in the universe Spiders, but it seems the filament is there.
The big question is, “Why do they spin?” Libeskind said. The Big Bang will not make the universe spin. Whatever makes the filaments spin must be from later history when the structure was formed, he said.
One possible explanation for this rotation is that the resulting shear forces can stir this material because the strong gravitational field of these filaments pulls the gas, dust, and other material within them to collapse. “However, we’re not really sure what could cause this magnitude of torque,” Libeskind said.
Scientists are now trying to understand the origin of filament spins through computer simulations of how matter behaved during the biggest cosmological sale. Explorers detailed their findings online June 14 in the journal Nature Astronomy.
