How does gravity work?

Gravity is a fundamental force of nature that attracts two objects with mass toward each other. It was first described by Isaac Newton in the 17th century and later refined by Albert Einstein’s theory of general relativity. Einstein explained gravity as the curvature of spacetime caused by massive objects like planets and stars. This curvature influences the motion of other objects, keeping planets in orbit around the Sun and the Moon around Earth. Gravity affects everything in the universe, from the formation of galaxies to everyday phenomena like objects falling to the ground.
