Dark matter and dark energy. “The Invisible Universe”

Around 85% of the matter in the Universe is dark, and of a type not understood by physicists. Although it doesn’t shine or absorb light, astronomers can detect this dark matter through its effect on stars and galaxies, specifically from its gravitational pull. A major project using ESO’s powerful survey telescopes is now showing more clearly than ever before the relationships between this mysterious dark matter and the shining galaxies that we can observe directly. Supercomputer calculations show how a Universe filled with dark matter will evolve. Over time dark matter will clump into a huge cosmic web structure, and galaxies and stars form where gas is sucked into the densest concentrations of dark matter.
