Distant galaxies and the true nature of dark matter

WebbDark Matter. Visible stars are not the only matter in space; in fact, the majority of matter in the universe is known as dark matter due to the fact that it cannot be directly observed. Instead, astronomers and cosmologists infer the existence of dark matter due to its gravitational influence on visible matter. highpoint lawn service rochester nyWebbIntroduction to Dark Matter. The current standard model of cosmology indicates the mass-energy balance of our universe to be: 4.9% - 'normal' matter. 26.8% - dark matter. 68.3% - dark energy. Therefore, dark matter makes up almost 85% of the total matter in the universe. However, physicists currently don't understand what dark energy or dark ... small scale chairs for bedroom
