The Greek philosophers were right: everything moves, everything changes. in fact the panta rei universal, the largest rotation of the Cosmos: the filaments where galaxies are concentrated, hundreds of millions of light years long but with a diameter of a few million light years, which envelop the universe in a cosmic network of light and dark matter interspersed from space of (almost) absolute vacuum, they rotate constantly. This is demonstrated by a study published in the journal Nature Astronomery. According to the authors of the study, the filaments of galaxies are the largest known rotating structures in the universe: So vast that individual galaxies appear in comparison as grains of dust, explains Noam Libeskind, of the German Leibniz Institute for Astrophysics of Potsdam, among the authors of the study. Rotation at such scales had never been noticed before.
Sloan Digital Sky Survey
The research was based on data collected by the observation program of the Sloan Digital Sky Survey (Sdss) and on computer simulations. Over 17,000 galactic wires were analyzed and, by studying the velocity of galaxies, it was found that the way they moved suggested that they were spinning with an elliptical motion and a speed of up to 360,000 kilometers per hour, or 1%. of the speed of light, around the central axis of single enormous filaments.
The rotation
There must be some as yet unknown physical mechanism that rotates these objects, continues Libeskind. According to current theory, the Big Bang would not have created a rotational movement in the Universe. We were convinced that at the level of the cosmic filaments the rotation of celestial structures on cosmic scales could stop, but we have to change our minds.
