Theories of Gravity

Gravity theories explain how objects attract each other. Newton's theory describes gravity as a force between masses, like how the Earth pulls us downward. Einstein's general relativity revolutionized this view, presenting gravity not as a force but as the bending of space-time caused by mass. Imagine placing a heavy ball on a stretched rubber sheet; it creates a dip, causing smaller balls to roll towards it. This theory explains not only why we stay grounded but also phenomena like black holes and the bending of light around massive objects. Each theory provides valuable insights into our understanding of the universe.
