Alternate Theories of Gravity

By: Joe P. Aristotelian Theory of Gravity


The Greek philosopherAristotle (384 BC – 322 BC) Had his own theory on gravity. He believed that all bodies move towards their natural space. He claimed that for some objects, their natural place is the center of the earth which would explain why they tend to fall towards it. He also claimed for other objects like gases and steam, the natural space is the heavenly spheres and the moon. This would explain why they move away from the Earth. He thought the speed of this motion is proportional to the mass of the object. Although these ideas of Aristotle are completely wrong, they are important since they were accepted for nearly two thousand years.

Le Sage's Theory of Gravitation


Le Sage’s theory is also commonly know as the kinetic theory of gravity which was originally proposed by Nicolas de Duillier in 1690. Gearges-Louis Le Sage later proposed it in 1748. His theory consists of an explanation for Newtons gravitational force. It explained the mechanial aspect of Newtons gravitational force as streams of tiny unseen particles impacting on all material objects from all directions. Le Sage called these useen particles ultra-mundane corpuscles. Any two material bodies tend to be driven together because they shield eachother from the impinging corpuscles, which results in a net imbalance in the pressure exerted by the impacting corpuscles onto the bodies.
