In particular, Sir Hermann Bondi proposed in 1957 that negative gravitational mass, combined with negative inertial mass, would comply with the strong equivalence principle of general relativity theory and the Newtonian laws of conservation of linear momentum and energy.
Jun 3, 2020 · 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.

The early sources of apergetic theory are science fiction novels of the late nineteenth century, including Percy Greg's Across the Zodiac (1880) and John Jacob Astor's A Journey in Other Worlds (1894), as well as writings on John Worrell Keely's alleged discoveries during that same time period.
Antigravity is a hypothetical force that acts in a direction opposite to that of normal gravity. More generally, it may refer to any means of modifying the effects of gravity, through some form of shielding or otherwise. Antigravity, gravity modification, and gravitational anomalies are subjects that have been considered both within and beyond ...
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 ...
apergy. Apergy is a fictional antigravity substance described by the author Percy Greg in his 1880 science fiction tale Across the Zodiac. Here are some extracts from the book that outline the concept: "I had satisfied myself that only one thing needful was as yet wholly beyond the reach and even the proximate hopes of science.
Mar 25, 2014 · One of the keys lies in free-fall experiments to measure the acceleration of gravity, g. These are notoriously difficult with charged particles, but first measurements on neutral antimatter have recently been made and there are plans for dedicated experiments on antihydrogen at CERN with AEgIS and GBAR. There are also schemes to study ...
