Revealing the Cosmos: The Dark Matter Revolution

This chapter explores the groundbreaking discoveries made by astronomers in the 1960s as they investigated the behavior of stars in the Andromeda galaxy using a new telescope. Focusing on the unexpected high speeds of these stars, it raises profound questions about the validity of Newtonian physics and introduces the concept of dark matter. The narrative emphasizes the rigorous scientific inquiry undertaken by Vera and her peers, which ultimately transformed our understanding of the universe's composition.
