How does gravity work?

Gravity is the force that attracts two bodies towards each other. This force depends on the mass and distance between the two bodies.

According to Einstein's theory of general relativity, gravity is not a force, but rather a curvature of spacetime caused by mass and energy. In this view, objects appear to move towards each other because they are following a straight path through curved spacetime.

Gravity is responsible for the formation and structure of galaxies, stars, and planets. It keeps us on the ground and determines the shape of the orbits of planets around the sun.

Scientists continue to study and explore the mysteries of gravity, and there is much that remains unknown about this fundamental force of nature.
