Dynamic theory of gravity

Nikola Tesla's dynamic theory of gravity is an alternative to Albert Einstein's theory of relativity. Tesla's theory (a model over matter and energy) was developed initially between 1892 and 1894, during the period that he was conducting experiments with high frequency and high potential electromagnetism, and was never published.

Though these principles guided his future research and experiments, Tesla did not announce it until near the end of his life. Tesla's proposition that gravity is a field effect is now given more serious consideration by some. At the time of his announcement, his critique on Einstein's work was considered by the scientific establishment to exceed the bounds of reason.

Dynamic theory of gravity

Tesla published a prepared statement on his 81st birthday (July 10, 1937) critiquing Einstein's theory of relativity. The following is a portion of that statement:

"... Supposing that the bodies act upon the surrounding space causing curving of the same, it appears to my simple mind that the curved spaces must react on the bodies, and producing the opposite effects, straightening out the curves. Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely impossible - But even if it existed it would not explain the motions of the bodies as observed. Only the existence of a field of force can account for the motions of the bodies as observed, and its assumption dispenses with space curvature. All literature on this subject is futile and destined to oblivion. So are all attempts to explain the workings of the universe without recognizing the existence of the ether and the indispensable function it plays in the phenomena."
"My second discovery was of a physical truth of the greatest importance. As I have searched the entire scientific records in more than a half dozen languages for a long time without finding the least anticipation, I consider myself the original discoverer of this truth, which can be expressed by the statement: There is no energy in matter other than that received from the environment." — Nikola Tesla

While this statement indicated that Tesla had "worked out a dynamic theory of gravity" that he soon hoped to give to the world, he reportedly died before he publicized the details. Few details were revealed by Tesla about his theory.

As an alternative to Einstein's relativity, the Dynamic theory of gravity explains the fields of gravity through electrodynamics. Tesla did not accept Einstein's special theory and its equating of matter and energy as delineated by relativity, nor of the curvature of space-time. Details of Tesla's theory that are available subsist of basic arguments against space being curved by gravitational effects, which leads some to believe Tesla failed to understand Einstein's theory is not about curved space at all, but curved space-time (though there is an disagreement about Tesla's exact understanding of Einstein's theories; Tesla was actively conducting his research during the time of Einstein's research ).

Tesla stated that there was no energy in matter other than that received from its environment. Tesla understood and did not accept the mass-energy equivalence as delineated by relativity. This mass-energy equivalence has been experimentally shown (in a variety of ways, the initial one being explained by special relativity is the photoelectric effect [though Tesla had explained the same phenomena years earlier (ed. see the photoelectric effect)] and, later, the comparisons of atomic masses [which "shows" that atomic nuclei weigh less than the sum of their parts]). Tesla rejected the central concept of relativity because of his prior works and research.

Theory structure

Tesla's theory states that the phenomena produced by electromagnetic forces is the most important phenomenon in the universe. According to gleanings from this theory, mechanicalal motions are universally a result of electromagnetic force acting through the mediums.

Tesla calls attention to a "field of force" being indispensable for explaining the movements of astronomical objects (a concept that fields model the phenomenon more preciselyly). This theory is a logical extension of the rotating magnetic field model. Dynamic theory of gravity does not include the "curvature of space". The theory claims four dimensions (x, y, z, t) and the field of force is not commutative. Einstein's theory of general relativity claims that space itself is curved as well as claiming that space-time is curved (the two according to Einstein are equivalent).

The theory refers to an aether, but Tesla's aether is not analogous to classical aether theories. The theory refers to an aether similar in terms to electromagnetics (and, ultimately, eliminates the concepts of aether as a medium [which is held by classical aether theories]). Lord Kelvin's explanation of the aether corresponds closely to Tesla's views of the aether. Tesla's aether is more akin to sound waves. Its properties varied according to velocity, frequency, resonance, the mediums, and the surrounding environment.

Tesla electromagnetics are composed of space-time potentials and their corresponding motion. This potential's motion caused in the surrounding mediums an equivalent and opposite effect (determining the positive and negative character of the medium).

Some elements of the theory may include:

Records seized

It is not clear if the full theory is recorded in any of Tesla's papers, as many of his effects were seized by the United States Federal Government immediately following his death in 1943 and declared Most Secret to prevent information about the theories and inventions Tesla was working on (some of them very dramatic, although apparently impractical, including a 'ray gun' intended to shoot down aircraft [referred to as teleforce]) falling into the hands of the axis powers. No papers relating to the theory of dynamic gravity are among the materials released under FOIA; some point out that Tesla generally did not write much down, and may have kept his work on gravity entirely in memory; others suggest that he did elaborate the theory in writing but that the materials have been kept classified.

Impact afterwards

At the time of his death, Tesla was considered a bizarre crackpot by many, due to his eccentric behaviour. Tesla's reputation as a "mad scientist" in later life means much of his later work was discredited or at least disregarded and ignored by the scientific establishment at the time. His controversial reputation was also exploited by the popular press and only served to enhance it. His "mad scientist" reputation and both the secrecy and the mysterious circumstances surrounding his death have allowed conspiracy theoristss to make additional propositions to the theory than Tesla revealed initially.
