a hypothetical force opposed to gravity
Also as adj.
Edison’s anti-gravitation under-clothing. Enables the Wearers thereof to suspend at will the Force of Gravity, so that they can Fan themselves gracefully about the Room.
Bronson, it appeared, was a daring aeronaut, who had made the attempt to fly to Mars in a newly invented ‘antigravitation machine’ known as the Insterstellar [sic] Express. He was now some ten or twelve hours overdue.
Gravity could be annihilated at will, and there was an enormous force at the disposal of the engineers, so cigar-shaped vessels were made perfectly air-tight, and fitted with engines for acting on the ether of space, and with the anti-gravitation apparatus.
No doubt in time we shall find means for negativing [sic] gravitation, but until that time such anti-gravitation machines must lie in the distant future.
In 1879 it was reported that Edison had made an invention for eliminating gravity… The ‘Wizard of Menlo Park’ has repeatedly come before the public with inventions which have proved to be products more of imagination than of possibility. At any rate, at that time there was a rumor current of Edison’s ‘Anti-Gravitation’; and a witty cartoonist of the time took advantage of this helpful substance.
A new theory of gravitation is proposed, according to which the extinction of a particle sets up quantized waves of curvature that constitute the gravitational field. Inversely, the origin of matter is the source of waves of anti-gravitation.
High technology—like antigravitation and intelligent machines—unworkable in densely occupied regions, can only blossom at the edges of the galaxy, and in fact the easier communications make them the real ‘center’ for travel and exchanges: civilization, in a word.
Ralf Brown suggested, from his etext collection, Homer Eon Flint's "The Lord of Death" (1919), and Hugo Gernsback's "Ralph 124C41+" (1911/1925) as likely sources for cites. We would like to see cites from the original print publication of these texts.
