In this episode of Amazing Universe, we explore the concept of cosmic time, which measures the age of the universe from the Big Bang to the present. The age of the universe is estimated to be about 13.8 billion years, determined through observations of the cosmic microwave background radiation, the expansion rate of the universe (Hubble's Law), and the study of ancient stars. Understanding cosmic time allows us to trace the history of cosmic evolution and predict the universe's future. This concept challenges our perceptions of permanence and highlights the dynamic nature of the cosmos.
