Heim theory, first proposed by German physicist Burkhard Heim publicly in 1957, is an attempt to develop a theory of everything in theoretical physics. The theory has received little attention in the scientific literature and is regarded as being outside mainstream sciencebut has attracted some interest in popular and fringe media.
Heim attempted to resolve incompatibilities between quantum theory and general relativity. To meet that goal, he developed a mathematical approach based on quantizing spacetime.Others have attempted to apply Heim theory to nonconventional space propulsion and faster than light concepts, as well as the origin of dark matter.
Heim claimed that his theory yields particle masses directly from fundamental physical constants and that the resulting masses are in agreement with experiment, but this claim has not been confirmed.
Heim theory is formulated mathematically in six or more dimensions and uses Heim's own version of difference equations.
Geoffrey A. Landis has compared the story behind the creation of Heim theory with the plot of a science fiction story.
...the idea relies on an obscure and largely unrecognized kind of physics...The majority of physicists have never heard of Heim theory, and most of those contacted by New Scientist said they couldn't make sense of Dröscher and Häuser's description of the theory behind their proposed experiment...The general consensus seems to be that Dröscher and Häuser's theory is incomplete at best...it has not passed any normal form of peer review.
So far Heim has not succeeded in finding a criterion which would limit the number of excited states to those actually observed. Despite the insight gained into particle physics, the theory is not entirely equivalent to modem quantum theory. This enables [Heim] to derive logically precise statements about the process of life, the origin of paranormal phenomena, and the structure of realms far transcending the 4-dimensional world of our experience.
