Structure of the Universe

We learned about dark matter in a previous chapter, but the search for dark matter in the universe is a truly amazing scientific endeavor. Scientists are not only looking to detect dark matter through telescopes but also through experiments buried deep beneath the surface of the earth. Watch The Absurd Search for Dark Matter from one of my favorite YouTubers, Veritasium.
Read 28.4 The Challenge of Dark Matter to understand the evidence for the existence of dark matter in galaxies and galaxy clusters, and the search for its nature, including the possibility of new types of particles.
Watch this excellent summary of our understanding of The Structure of the Universe.
Read 28.5 The Formation and Evolution of Galaxies and Structure in the Universe to explore theories on the formation of galaxies and larger structures in the universe.
Astronomers use supercomputers to simulate the formation of our universe and the development of structure among the galaxies. Browse this video from the Mira Supercomputer (there is no sound in the video) to see how complex and enormous these simulations are. It’s amazing that understanding the universe requires collaborations between astronomers, physicists, computer scientists, and engineers.
