The term antimatter was first used by Arthur Schuster in two rather
whimsical letters to Nature in 1898, in which he coined the term.
He hypothesized antiatoms, as well as whole antimatter solar systems,
and discussed the possibility of matter and antimatter annihilating
Antimatter From Wikipedia
The idea of antimatter seems to have been part of the ancient secret canon that Newton, Kepler and others were privy to:
The Repulsine, UFO's and Flying Saucers of Nazi Germany
It was nearly the end of WWII. At that same time, scientist Viktor Schauberger worked on a secret project. Johannes Kepler, whose ideas
Schauberger followed, had knowledge of the secret teachings of
Pythagoras that had been adopted and kept secret. It was the knowledge
of Implosion (in this case the utilization of the potential of the
inner worlds in the outer world). Hitler knew - as did the Thule and
Vril people - that the divine principle was always constructive. A
technology however that is based on explosion and therefore is
destructive runs against the divine principle. Thus they wanted to
create a technology based on Implosion. Schauberger's theory of
oscillation (principle of the overtone sequence, monochord) takes up
the knowledge of Implosion. To put it simply: Implosion instead of
Explosion! Following the energy paths of the monochord and the
implosion technology one reaches the realm of antimatter and thus the
cancellation of gravity.

Schauberger's theory is also claimed by others to have had connections with the ancient Vimanas and Sumerian legends of antimatter and implosion that the Nazis were working on.
"German UFO literature very often conforms largely to documented history on the following points: ...
Nazi Germany conducted research into advanced propulsion technology, ... Viktor Schauberger's engine research, ...."
"This article deals with a military black project. Because of the nature of such projects, the most authoritative sources (any involved governments and defense contractors) may not even acknowledge its existence. The most reliable sources may be highly speculative."

"Implosion is no invention in the conventional sense, but rather the renaissance of ancient knowledge, lost over the course of time."

"You must learn to think one octave higher. Only then will you learn how implosion energy works."

The implosive forces in Schauberger's turbines were compared to those found in tornadoes and hurricanes.
