Exploring the Universe and Dark Matter

The video explores the concept of model universes and the role of dark matter in the formation and evolution of galaxies. It explains that dark matter, which makes up 85% of the universe's mass, is invisible but crucial for galaxy formation. The video discusses current research methods to detect dark matter and the importance of understanding it for a new physics paradigm. It highlights the use of galaxy mapping to infer dark matter properties and the ongoing quest to identify its nature.
