According to Sir Issac Newton's discovery of the law of gravity, all objects in the universe are drawn to one another by a force known as gravity. This force is inversely proportional to the square of the distance between the objects and immediately relates to their masses.

 In addition to causing objects to fall to the earth, gravity is what keeps the planets in their orbits around the sun. It is a basic force of nature that controls how celestial bodies move and has an impact on every part of human existence on Earth. 

Gaining an understanding of the law of gravity has helped scientists develop their knowledge of physics, astronomy, and engineering, resulting in significant discoveries and innovations that have influenced the modern world.
