Gravity is a fundamental force that governs the attraction between objects with mass. It was first described by Sir Isaac Newton in the 17th century, who proposed that every object in the universe exerts an attractive force on every other object. The strength of this force depends on the masses of the objects involved and the distance between them. Newton’s law of universal gravitation was revolutionary, explaining everything from the fall of an apple to the Earth to the motion of planets in orbit around the Sun. This theory laid the foundation for classical mechanics and has been confirmed through centuries of observation.

However, in the early 20th century, Albert Einstein's theory of general relativity provided a deeper understanding of gravity. According to Einstein, gravity is not just a force but a curvature in the fabric of spacetime caused by the mass of objects. In simple terms, large objects like planets and stars warp the space around them, and this curvature causes smaller objects, like satellites or the Moon, to move in curved paths. Einstein’s theory has been supported by various experiments, including the observation of light bending around massive objects and the detection of gravitational waves. Gravity plays a crucial role in shaping the structure of the universe, from the formation of galaxies to the motion of celestial bodies. Shutdown123
