#rsisb Roll no.239 Foundation Level “Atoms and Eternity: How Chemistry Shapes the Cosmos” explores the fascinating connection between the tiny world of atoms and the enormous universe. Everything around us—from stars and planets to water, rocks, plants, and living organisms—is made of atoms. Chemistry explains how atoms combine to form molecules and materials. Inside stars, nuclear processes create many of the elements that later become part of planets and living things. Over billions of years, these elements travel through space and become ingredients for new stars, worlds, and life. The topic reminds us that the same fundamental building blocks found throughout the cosmos also make up our own bodies. In this sense, chemistry connects the smallest particles to the vast story of the universe. Key idea: Atoms may be incredibly small, but their interactions shape everything we see—and their story reaches across cosmic time.
