Large-scale structure of the Universe
The Large Scale Structure incorporates the notion of all the content in the universe which includes Galaxies —most of them bound in Galaxy clusters and Superclusters,Dark matter and Dark energy. While precise figures are impossible to acquire, it is currently thought that Dark Energy makes up 68% of the universe, Dark Matter follows with 27%, Radiation (Neutrinos and Photons) consisting of 0.1-0.2% meanwhile matter (anything made up of Atoms) consists of 4.9%. Other revised studies suggest that Dark Energy makes up 70% of the universe, Dark Matter following suit with 25%, Free Hydrogen and Helium make up ~4%,Neutrinos constituting 0.3% and other chemical elements constituting 0.003%.
