3D map which shows the evolution of galaxies The 3D map developed by the Max Planck Institute of Astronomy in Germany shows the large-scale distribution of matter about three billion years after the Big Bang : at the time, the universe measured 2.5 million light years in width, 6 in height and 100 in length. Inside, the invisible cosmic scaffolding on which the clusters of galaxies have thickened due to the gravitational force. Credit: Meteoweb.eu | Space-Time
