The Universe's Biggest Twister: A Gigantic Spinning Cosmic Filament! Astronomers have just confirmed the largest rotating structure ever observed—a colossal cosmic filament over 140 million light-years long, slowly twisting like an immense whirlpool through the voids of space.These massive threads of dark matter and gas form the scaffolding of the cosmic web, linking galaxy clusters. Yet detailed Sloan Digital Sky Survey data reveals this one is spinning: hundreds of thousands of embedded galaxies spiral around its axis at hundreds of kilometers per second.This staggering coherent rotation hints at primordial angular momentum baked into the early Universe, challenging models of how gravity and dark matter built the cosmos. What ancient force set such a vast structure spinning?Source: Nature Astronomy / Leibniz Institute for Astrophysics Potsdam (AIP)
