Gravity Explained concisely

Bac

Last update :

Gravity is a fundamental force in physics that attracts objects with mass towards each other. It was first described by Sir Isaac Newton in the late 17th century. The strength of gravity depends on the masses of the objects involved and the distance between them.

Albert Einstein's theory of General Relativity, developed in the early 20th century, provided a more comprehensive understanding of gravity. According to General Relativity, gravity is not just a force but a curvature of spacetime caused by mass and energy.

The force of gravity keeps planets in orbit around stars, binds galaxies together, and determines the overall structure of the universe. It is responsible for objects falling to the ground and is the reason why we have weight on Earth.

Gravity also plays a crucial role in astrophysics, explaining the formation of stars, galaxies, and black holes. Additionally, it influences the behavior of light, causing gravitational lensing.

In summary, gravity is a fundamental force that governs the motion of objects in the universe and shapes the structure of space and time.
