Who Discovered Gravity before Newton?

No comments

Before Newton, there were several scientists who contributed to the understanding of gravity. The ancient Greeks like Aristotle, Pythagoras, and Democritus had their theories about gravity. Archimedes, Galileo, and Kepler also made significant contributions to the study of gravity. However, their understanding of gravity was incomplete, and they did not come up with the laws of gravity that Newton discovered. It was only through Newton’s groundbreaking work that the laws of gravity were explained, and modern physics was born.

Welcome, fellow readers! Have you ever wondered who discovered gravity before Sir Isaac Newton did? People are often quick to credit Newton with the laws of gravity that we have come to know and understand, but there were other scholars before him who played a role in unraveling the mysteries of gravity. Aristotle, Pythagoras, Democritus, Archimedes, Galileo, and Kepler were among those who made substantial contributions in the study of gravity. Despite their contributions, it was Newton who truly revolutionized the field and provided us with a comprehensive understanding of this fundamental force.

Who Invented Gravity Before Newton?

Gravity is a fundamental force that holds the universe together. Its discovery and development as a concept took centuries, and many scholars and scientists contributed to our understanding of gravity before Sir Isaac Newton formulated his gravity theory in the 17th century.

Ancient Greek Views on Gravity

The Ancient Greeks were among the first to propose ideas about gravity. They believed that all matter was made up of certain elements, and that heavier objects fell towards the Earth’s center because they were made up of more Earth-like elements. This theory of gravity held for several centuries in ancient Greece, and its influence can be seen in the works of many famous philosophers such as Aristotle and Ptolemy.

Aristotle was one of the first to propose the idea that all objects have a natural motion to seek their natural place. He believed that heavy objects fell to the ground because the earth was their natural place. Ptolemy, on the other hand, believed that the Earth was the center of the universe and that the planets and stars moved around it in concentric spheres. He also proposed an early form of gravitational theory that stated the heavier an object was, the faster it would fall to the ground.

Arab Scholars’ Contributions to Gravity

The Arab world was a hub of scientific and intellectual activity during the medieval period. Arab scholars such as Al-Kindi and Al-Farabi believed in the concept of gravity and contributed to the development of the laws governing it. They also made significant contributions to the sciences of physics and astronomy that influenced later European thinkers.

Al-Kindi, for example, suggested that the force of gravity moved celestial bodies in the heavens, which was a significant departure from previous theories that held that angels moved the planets and stars. Al-Farabi, meanwhile, suggested that gravity was not simply a force of nature but was also associated with an object’s innate properties.

The Work of Robert Hooke

Robert Hooke was a British polymath who lived and worked in the 17th century. Although he is perhaps best known for his work with microscopes and cell theory, he also contributed to the development of gravity theory. Hooke suggested an inverse-square law of gravitation which he presented publicly in 1666, several years before Newton.

Although Hooke’s work did not gain widespread recognition, it was influential in the development of gravity theory and was cited by both Newton and later scientists such as Albert Einstein. Hooke’s inverse-square law suggested that the gravitational force between two objects decreased as the distance between them increased. This idea would later be expanded upon by Newton in his laws of motion and universal gravitation.

In conclusion, gravity has been a topic of fascination for scientists and scholars throughout history. Although Newton is often credited with the discovery of gravity, ancient Greeks, Arab scholars, and Robert Hooke all made significant contributions to our understanding of gravity. Their ideas and theories paved the way for the development of one of the most important concepts in physics, and their legacy can still be seen today in science and technology.

Who Invented Gravity Before Newton?

Gravity is the force that pulls two objects toward each other. It is present everywhere in the universe and affects everything that has mass. Humans have been studying gravity for thousands of years, and several notable minds contributed to our understanding of it before Sir Isaac Newton. In this article, we’ll explore some of the significant figures that tackled the concept of gravity before Newton and helped pave the way for his groundbreaking laws.


Archimedes, a Greek mathematician, physicist, and engineer, made numerous contributions to the field of science, including his work on buoyancy principles, which helped establish a basic understanding of gravitational principles. Archimedes started to formulate the concept of gravity after observing that objects get heavier when they are underwater than they are in air. He also realized that the displacement of water was equal to the volume of an object and could be used to measure the object’s density.

Archimedes correctly concluded that the Earth’s gravitational force pulls everything towards its center, and the more massive the object, the stronger the force. He further measured the force of the planet Earth’s gravitation by calculating the weight of different objects on Earth compared to their weight on the moon.

Galileo Galilei

Galileo, an Italian scientist and mathematician born in Pisa in 1564, is known for his many contributions to science. However, one of his most significant contributions was his work on gravitation. Galileo believed that all objects would fall at the same rate if there were no friction in the way and he supported the theory that the rate at which an object falls depends not on its weight, as was generally thought, but on its shape and density.

Galileo also made the observation that a force is needed to maintain the motion of an object on a surface without friction. He concluded that a force would be necessary to maintain an object’s motion through space, even if it is not constantly pushing the object forward. Galileo’s experiments paved the way for Newton to develop the concept of inertia, which is the tendency of an object at rest to remain at rest and an object in motion to continue moving at a constant velocity.

Johannes Kepler

Johannes Kepler was a German astronomer, mathematician, and astrologer who played a significant role in the scientific revolution of the 17th century. One of Kepler’s most significant contributions to the field of science was his work on the laws of planetary motion, which provided a better understanding of the solar system’s dynamics. Kepler’s work also led to the discovery of elliptical orbits and the realization that the planets move according to mathematical laws.

Kepler’s theory of gravitation is based on the idea that the planets are attracted towards the Sun, and the force that attracts them was probably related to the rotation of the Sun around itself and this force decreases as the distance from the Sun increases. Kepler’s laws paved the way for Newton to develop the universal law of gravitation.


Before Isaac Newton, there were several scientists who tried to understand the principles behind the force of gravity and how it affects our universe. Though their theories were not as detailed as Newton’s scientific laws, they built the groundwork for today’s understanding of the fundamental force that affects everything in our universe.
