The Cosmic Cocktail: Three Parts Dark Matter

"The Cosmic Cocktail: Three Parts Dark Matter" by Katherine Freese explores how dark matter—an invisible, mysterious substance that makes up about 27% of the universe—shapes our cosmos. The book explains that dark matter isn't just an empty presence; it influences galaxy formation and holds galaxies together with gravity. Freese discusses how scientists hunt for dark matter through experiments and theories, highlighting its crucial role in cosmic evolution. Overall, the "cosmic cocktail" refers to the universe's composition: roughly a third ordinary matter, a third dark matter, and a third dark energy, revealing a complex and fascinating universe beyond what we see.
