 Electrogravitics had its origins in experiments started in 1921 by Thomas Townsend Brown (who coined the name) while he was still in high school.He discovered an unusual effect while experimenting with a Coolidge tube, a type of X-ray vacuum tube where, if he placed on a balance scale with the tube’s positive electrode facing up, the tube's mass seemed to decrease, when facing down the tube's mass seemed to increase.Brown showed this effect to his college professors and even newspaper reporters and told them he was convinced that he had managed to influence gravity electronically.
