Gravity

Gravity is a fundamental force of nature that attracts two objects towards each other. It is one of the four known fundamental forces, along with electromagnetism, the strong nuclear force, and the weak nuclear force. Gravity is responsible for the motion of planets, stars, and galaxies, as well as the structure of the universe. It is also the force that keeps us grounded on Earth.

Gravity was first described by Sir Isaac Newton in his law of universal gravitation, which states that

Albert Einstein's theory of general relativity provides a more comprehensive description of gravity. According to this

Gravity plays a crucial role in various phenomena, such as the formation of stars and planets, the
