Largest Rotating Structures in the Universe Discovered – Fantastic Cosmic Filaments Where Galaxies Are Relatively Just Specs of Dust
SciTechDaily | Leibniz Institute for Astrophysics | June 16, 2021“Despite being thin cylinders – similar in dimension to pencils – hundreds of millions of light years long, but just a few million light years in diameter, these fantastic tendrils of matter rotate,” adds Noam Libeskind, initiator of the project at the AIP. “On these scales the galaxies within them are themselves just specks of dust. They move on helixes or corkscrew-like orbits, circling around the middle of the filament while travelling along it.
“Such a spin has never been seen before on such enormous scales, and the implication is that there must be an as yet unknown physical mechanism responsible for torquing these objects.”
How the angular momentum responsible for the rotation is generated in a cosmological context is one of the key unsolved problems of cosmology.
