In the 6th century CE, the Byzantine Alexandrian scholar John Philoponus proposed the theory of impetus, which modifies Aristotle's theory that "continuation of motion depends on continued action of a force" by incorporating a causative force which diminishes over time.
Apergy. Apergy is a fictitious form of anti-gravitational energy first described by Percy Greg in his 1880 sword and planet novel Across the Zodiac. John Jacob Astor IV used it in his 1894 science fiction novel A Journey in Other Worlds.
In 1896, "apergy" was used by writer/philanthropist Clara Jessup Bloomfield-Moore for the force behind John Ernst Worrell Keely 's Vibrodyne (aka Keely's Motor). In her "Some Truths About Keely", Bloomfield-Moore identifies apergy as "one of the currents of a triune polar stream of force". Keely and his Vibrodyne.
Feb 12, 2016 · Our understanding of gravity has gone through a few permutations, from Newton’s equations through to Einstein’s general relativity. With today’s discovery of gravitational waves, we look ...
The theory explained the anomalous orbit of Mercury, but the first major triumph came in 1919 when Arthur Eddington and his colleagues measured the influence of the Sun’s gravity on light from stars during a total solar eclipse. Physicists made many exotic predictions using general relativity.
Mar 25, 2019 · Einstein Redefines Gravity . The next major step in our understanding of gravity comes from Albert Einstein, in the form of his general theory of relativity, which describes the relationship between matter and motion through the basic explanation that objects with mass actually bend the very fabric of space and time (collectively called spacetime).
Aug 11, 2021 · Einstein’s theory of gravitation is expressed in one deceptively simple-looking tensor equation (tensors are a generalization of scalars and vectors), which expresses how a mass determines the curvature of space-time around it.
