Astrophysics is the branch of science that uses the laws of physics to understand the universe. Unlike astronomy, which focuses on observing celestial objects, astrophysics seeks to answer: What are stars made of? How do galaxies form and evolve? What happens near black holes? How did the universe begin? What is dark matter and dark energy? Astrophysics transforms points of light in the sky into physical systems governed by measurable laws. This course guides students from classical celestial understanding to modern cosmic physics, without overwhelming mathematics.
