The Big Bang and Radioactivity
Learning Time: 5-15 hours
Content: The Big Bang and radioactivity is a subject that examines the formation of the universe and the instability of atomic nuclei. This subject covers the Big Bang theory (expansion of the universe), cosmic background radiation, radioactive decay (alpha, beta, gamma), half-life, and practical applications. TYT focuses on basic concepts, while AYT focuses on the evolution of the universe and nuclear physics. The current 2025 curriculum also covers dark matter and nuclear medicine. Learning this topic forms the basis for cosmology and nuclear technology.
