  • The State of Experimental Evidence for Length Contraction, 2002 (2002) [Updated 6 years ago]
    by Delbert J. Larsen   read the paper:

    The idea that physical objects become shorter as they move is now well established in physical theory. Both the classical theories of Lorentz, Larmor, Fitzgerald and Poincare and the more radical special theory of relativity of Einstein incorporate a physical length contraction into their worldview. However, no direct measurement of length contraction has ever been done. One experiment that tried to observe the effect of a length contraction was done by Sherwin, who found no evidence of a length contraction. This paper will analyze the assumptions underlying Sherwin's experiment to show that Sherwin's experiment is in fact equivocal concerning the existence of a length contraction. This paper will also make mention of another important recent observation that has relevance to the issue of the existence of physical length contraction.


  • Do Working Particle Accelerators Prove That Special Relativity Is Correct? (2001) [Updated 5 years ago]

  • An Absolute Theory for the Electrodynamics of Moving Bodies (1999) [Updated 6 years ago]

    An axiomatic set employing clock retardation alone is shown to be sufficient to derive the Lorentz kinematic transformations; the Fitzgerald length contraction is not required. Since the kinematic transformations lead solely and directly to the electrodynamic transformation, this paper presents the third axiomatic set (the others are due to Lorentz and Einstein) consistent with presently accepted electrodynamic theory. The theory proposed herein assumes classical concepts for space and time; Galilean relativity and an aether are assumed. The present experimental evidence relative to space-time theory is reviewed, and its relevance to the three competing axiomatic sets is discussed. It is shown that the new theory requires the Michelson-Morley experiment to be explained by a node enforcement hypothesis. Shortcomings in the Einstein theory include measurements of EPR phenomena. while shortcomings of the Lorentz theory may result from the tests due to Sherwin. Two new tests are proposed that could experimentally prove which axiomatic set best represents reality.


  • A Derivation of Maxwell's Equations from a Simple Solid Two-Component Aether (1999) [Updated 6 years ago]

    Transverse vibrations of solids. such as waves on a string. exhibit many of the properties of light. Physicists in the 1890' s therefore anticipated that light was also the result of a solid oscillation, and the solid underlying light waves was identified as a new substance. the aether. Einstein's special theory of relativity (SRT) abandoned the aether as superfluous, but persistent troubling problems in physics (such as EPR phenomena) require that we explore alternatives to SRT. and a return to aether science is one exciting alternative. A mathematically rigorous derivation of Maxwell's Equations will be presented based on a simple solid aether model. It will be shown that such a model naturally unifies the two types of currents (moving charge and displacement) which exist in the Maxwell theory. Charge conservation and the absence of magnetic monopoles are readily explained. Physical models result for fields and charges. An experiment is proposed which may lead to a test of the proposed theory.


  • Deriving Maxwell's Equations from a Postulated Two-Component Solid Aether (1998) [Updated 6 years ago]

    Special relativity abandoned the aether as superfluous. but recent tests involving verification of Bell's inequality call into question the validity of special relativity. Therefore. a re-examination of the classical concept of an aether is once again of considerable scientific interest. A postulated two-component solid aether can be used as a mechanical model to arrive at an axiomatic foundation for Maxwell's Equations. Simple axioms governing the solid aether are proposed that can be manipulated via traditional vector calculus to mathematically derive Maxwell's equations. The mechanical model for the aether leads to further physical interpretations for quantities such as electric charge. electric currents. the displacement current. electromagnetic waves and the scalar and vector potentials. Significantly. the model results in a unified physical interpretation for the displacement and electric currents.
