Gravity

Gravity is better known as force. The first to make its discovery was Newton. The legendary story goes that Isaac Newton was once sitting under an apple tree, when an apple fell on his head. It led him to wonder what was the force that pulled the apple to the ground. Thus the concept of gravity was born. Then a physicist named Albert Einstein used gravity to explain why planets orbit around the sun. This led to the discovery of a lot of different theories such as dark matter and quantum gravity.
