Autodynamics was proposed by physicist Ricardo Carezani in the early 1940s as a replacement for Einstein's theories of special relativity and general relativity.
Society for the Advancement of Autodynamics
Very few papers on autodynamics have appeared in the scientific literature, after the original publication by Carezani. (A rare example from 1997 is cited below. We note that Physics Essays is a journal which traditionally publishes papers which for one reason or another cannot be readily published elsewhere.)
However, the theory has been championed outside the mainstream scientific literature by the [Society for the Advancement of Autodynamics] (SAA), an organization founded by David de Hilster of Long Beach, California. The SAA sells Carezani's two books on autodynamics at its webpage.
According to the SAA website, Carezani proposed his theory "after he found a mathematical error in Einstein's calculations for the theory of relativity." Nonetheless, as the SAA admits, "currently, there are no known physicist(sic) that support Autodynamics."
In 2005, a company called Bootstrap Productions, which is apparently owned by de Hilster, produced a documentary, [Einstein Wrong: The Miracle Year]. The film follows for one year David de Hilster and his mother "as they enter the underworld of physics to take on relativity and the icon of 20th century physics".
Main tenets of autodynamics
The primary claim of Autodynamics is that the equations of the Lorentz transformation are incorrectly formulated to describe relativistic effects, which would invalidate special relativity and general relativity. The effect of the revised equations proposed in Autodynamics is to cause particle mass to decrease with particle velocity, being exchanged with kinetic energy (with mass being zero and kinetic energy being equal to the rest mass at c). This exchange between mass and energy is the proposed mechanism underlying most of the derived conclusions of Autodynamics.
Secondary claims of Autodynamics include:
- the nonexistence of the neutrino,
- the existence of additional particles that have not been observed by mainstream physicists (including the "picograviton" and the "electromuon"),
- the existence of additional decay modes for muons and interaction modes for energetic atomic nuclei.
Scientific status of autodynamics
A 1999 article in the popular magazine Wired[2] quotes Pierre Noyes, a professor at the Stanford Linear Accelerator Center, as claiming "most scientists consider Autodynamics little more than a 'crackpot theory'". Despite this, Noyes et al. performed an experiment in an attempt to compare the predictions of SR and AD, but concluded that the values calculated by SR were significantly closer to what was observed[9]. Carezani later argued that the experiment was not relevant for comparing the two theories by pointing out that AD applies specifically to decay cases, yet the electrons in the Noyes experiment received energy from the external medium (klystron EM field)[10]. Nobel Laureate Dr. Luis Alvarez of the University of California, Berkeley was interested in helping Carezani design an improved version of this experiment[4]. According to Lee Smolin, a physics professor at the Perimeter Institute and adjunct at the University of Waterloo[2], that there has been "no serious attempt [by the autodynamics supporters] to make an argument or to discuss experimental data that refute their basic claims". Autodynamicists reject these claims[3].
Special relativity, in its pure form, is proven to be mathematically consistent (see the Special relativity article). Although AD supporters present several examples of purported "inconsistencies" on its Web pages, these examples do not correctly utilize SR to begin with. For example, on [7], a Lorentz contraction is incorrectly applied to the distance between a stationary observer and a moving object. On [6], the AD authors incorrectly claim that reference frames are "unnecessary" and "cannot be measured". On [8], the AD authors label a Lorentz length contraction as an "extra velocity" and attribute energy to it; this leads to the claim that SR do not conserve energy and momentum. (This claim further rests on the AD assumption that the neutrino does not exist.) However, relativistic energy-momentum conservation has been tested extensively in neutrinoless phenomena.
For these reasons, Autodynamics cannot be considered to be part of mainstream science.
Addition of Velocities in Autodynamics
According to [5], the AD Sum Velocity equation is:
- [\beta_n=\sqrt^2)} ]
For a body undergoing mass decay, AD relates mass, velocity and kinetic energy as follows[9]:
- [ m=m_0 \sqrt]
- [ KE=m_0c^2\bigg(1-\sqrt\bigg)]
- [ m_=m_=m_\sqrt^2}]
- [ KE_n=KE_1 + KE_2 + \cdots + KE_]
However, this marks a very significant advantage Special Relativity has over autodynamics; at speeds much less than the speed of light, the Lorentz transformations reduce to the Galilean transformations, and Special Relativity agrees with common experience. Autodynamics does not appear to do so.
