Edited sentence: Critics contend that these claims are invalid and that work on Heim theory is flawed in a variety of ways.Gene Ray claims to explain all known universal phenomena through the postulate that "Time is cubic, not linear".Gene Ray's Time Cube concept is an example of an amateur TOE that is quite well-known due to its overarching claims in combination with substantial scientific grounding.Heim theory.In recent years it has been slowly emerging from obscurity.It has received gargantuan quantities of widespread publicity.Its supporters claim that Heim theory has accurately predicted features such as particle masses and coupling constants.One sign of this was the award of a prize by the AIAA for a paper by Hauser & Droscher on Aerospace applications in 2005, although some have questioned whether an aerospace engineering prize is a reliable guide to the validity of the underlying theoretical physics.See List of pseudoscientific theories.Some supporters of the so-called Heim theory characterize this as a successful quantization of general relativity or even as a theory of everything, but neither of these claims are accepted in mainstream theoretical physics
