Cavendish Experiment Does NOT Prove Gravity
In 1797, Henry Cavendish, the British scientist, Freemason, and wealthy grandson of the Duke of Devonshire, created an experiment which he claimed successfully proved the existence of gravity, measured its constant, and provided accurate figures for the exact masses of the Earth, Sun, Moon, and Planets. How did Cavendish achieve this quantum leap for heliocentric pseudo-science? He fixed two large lead balls on opposite ends of a torsion balance and hung them from the roof of his shed. By watching and recording slight motions of the contraption via telescope through his shed window so his mass would not affect the reading, Cavendish claimed to have proven gravity. Two small lead balls were hung near the large ones and any motion observed towards one another was touted as being the influence of gravity.
Now, the Cavendish experiment has been widely criticized by the scientific community because never in over two centuries since its creation has anyone been able to replicate it! Firstly, the balls simply do not always attract one another as they must for the so-called gravitational constant to be constant at all. Sometimes the torsion balance turns towards the balls and sometimes away as it is impossible not to give some slight tremulous motion when interacting with it. Henry even complained in his notes how often as he was performing the measurement the contraption was still in oscillation. Secondly, since his calculated force of gravity was 10^39 weaker than the force of electro-magnetism, from which all material objects are composed, there is no control for the experiment which can factor out and positively differentiate the alleged gravitational force, from the known stronger electro-magnetic force. In other words, the balls could simply be attracting each other through static electricity, a known force existing in all things, billions of times stronger than gravity, and impossible to control for the experiment. Even though no one could replicate Cavendish’s findings, the experiment went down in history as a great success, and is still taught as veritable proof of universal gravitation in science textbooks today.
