Gravity theories explain how objects with mass attract each other. The most well-known theory is Isaac Newton's law of universal gravitation, which states that every mass attracts every other mass with a force proportional to their masses and inversely proportional to the square of the distance between them. This theory effectively describes gravity in everyday situations and was a cornerstone of classical physics. Another significant theory is Albert Einstein's general relativity, which redefined gravity as the curvature of spacetime caused by mass. According to this theory, massive objects like planets and stars warp the fabric of spacetime, causing other objects to follow curved paths. General relativity has been confirmed through various experiments and observations, especially in extreme conditions like near black holes.
