{{reflist | 30em}}
Special relativity, in its pure form, is proven to be mathematically consistent (see the ] article). Alleged errors have been documented in the on-line literature that attempts to support autodynamics, including:

*a Lorentz contraction is incorrectly applied to the ''distance between'' a stationary observer and a moving object.{{ref_label|auto_frames|7|a}}
*the claim that reference frames are "unnecessary" and "cannot be measured" is incorrect.{{ref_label|auto_galilean|6|a}}
*a Lorentz length contraction is incorrectly described as an "extra velocity" and energy is incorrectly attributed to it leading circularly to the claim that special relativity does not conserve energy and momentum..{{ref_label|auto_systems|8|a}}
*the above claim is further bolstered by autodynamics assumption that the neutrino does not exist, even though relativistic energy-momentum conservation has been tested extensively in neutrinoless phenomena.{{ref_label|auto_galilean|6|a}}

==Problem of velocity addition in autodynamics==

The autodynamics velocity addition equation is{{ref_label|auto_sum|5|a}}:
:<math>\beta_n=\sqrt{1 - (1-\beta_1^2)(1-\beta_2^2) \cdots (1-\beta_{n-1}^2)} </math>

where <math>\beta=\frac{v}{c}</math>

For common experiences where <math>v << c</math>, this reduces to
:<math>v_n=\sqrt{v_1^2+v_2^2+ \cdots +v_{n-1}^2}</math>

This fact marks a significant advantage ] has over autodynamics; at speeds much less than the ], the ] reduce to the ], and Special Relativity predicts for <math>v << c</math> the expected result:
:<math>v_n=v_1+v_2+ \cdots +v_{n-1}</math>

From this it is clear that autodynamics contradicts common experience. For example, if an object that was traveling at a velocity of 3 meters per second with respect to a stationary observer were to measure a third object moving in the same direction to have a velocity of an additional 4 meters per second, autodynamics would predict that the stationary observer would measure a velocity of approximately <math>\sqrt{3^2+4^2}=5</math> meters per second while special relativity would predict a velocity of approximately <math>3+4=7</math> meters per second. Thus, this prediction of autodynamics is contradicted by simple ] experiments (including such basic ones as those that occur when moving in common modes of transport such as automobiles, trains, and airplanes).

Autodynamics was a physics theory proposed by Ricardo Carezani (1921–2016) in the early 1940s as a replacement for Einstein's theories of special relativity and general relativity. Autodynamics never gained status as a viable alternative model within the physics community, and today is wholly rejected by mainstream science.

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, general relativity, and Maxwell's equations. 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.

Ancillary predictions 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.

Status of autodynamics

Autodynamics is wholly rejected by the mainstream scientific community. Since Carezani's original publication, no papers on autodynamics have appeared in the scientific literature, except for additional papers by Carezani published in alternative journals such as Physics Essays. A 1999 article in the magazine Wired quotes H. Pierre Noyes, a professor at the Stanford Linear Accelerator Center, as stating, "autodynamics was disproved. Special relativity is correct" and noting that "mainstream physicists have considered autodynamics a crackpot theory for decades". Noyes was a researcher in an experiment attempting to compare the predictions of SR and AD, and concluded that the values calculated by SR were significantly closer to what was observed. 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). According to Lee Smolin, there has been "no serious attempt to make an argument or to discuss experimental data that refute their basic claims".
