Dark matter and dark energy

The document discusses the composition and structure of the universe, focusing on dark matter and dark energy. It explains that dark matter makes up 84.5% of the total matter in the universe and was first discovered in 1933, though its nature remains unknown. Theories suggest dark matter could be composed of supersymmetric particles or exist in a "hidden valley." Additionally, dark energy is thought to make up 70% of the universe and acts as a repulsive force associated with the vacuum of space.

INDEX 1. Structure of the Universe 2. What is Dark Matter? 3. Discovery of Dark Matter 4. Structure of Dark Matter
INDEX 5. Types of Dark Matter - Baryonic and Non-Baryonic Dark Matter - Hot and Cold Dark Matter 6. Dark Energy
Structure of the Universe - Common Matter - Dark Matter - Dark Energy
What is dark matter? - Invisible matter, it does not emit nor absorb light - Gravitational effects on visble matter - 84.5 % of the total matter of the Universe
Discovery of Dark Matter - Fritz Zwicky in 1933 - ¿Matter disappeared or invisible matter? - Galaxies
Structure of Dark Matter Theories: - Supersymmetric particles - Light enough to be produced at the LHC - Hidden Valley
Baryonic Dark Matter - Dark matter composed of baryons - Examples of baryonic Dark Matter: MACHOs, brown dwarfs, non luminous gas
Non-Baryonic Dark Matter - Most Dark Matter is non-baryonic - We need this Dark Matter to help turn density fluctuations in the early universe to the galaxies, clusters, filaments, walls and voids we see today
Hot and Cold Dark Matter - Movement of particles compared to speed light - Cold Dark Matter collaps forming structures - Explanation of the formation of galaxies
Dark Energy - 70% of the Universe - Associated with the vacuum space - Evenly distributed trough the Universe, not only in space, but also in time - Repulsive force - It can be measured how there is
