Alternative to the principle of constant speed of light

摘要

To consider a medium carrying light and electromagnetic waves is impossible,when this medium shall have properties according to the principle of constantspeed of light, that is, isotropy of speed of light in every system ofreference. Therefore, with principle of constant speed of light abandoned, theso-called medium synchronization of clocks is defined, yielding isotropy solelyin the system at rest and anisotropy in all moving systems. From mediumsynchronization the appropriate coordinate transformation is developed, theso-called medium transformation, a Galilean type of transformation, thusmaintaining simultaneity between all participant systems of reference andchanging the form of Maxwells equations to the extended Maxwell equations.Despite the fact that medium transformation violates Lorentz invariance and theprinciple of relativity, it is demonstrated that the results from mediumtransformation and extended Maxwell equations are fully compliant withobservable phenomena. Moreover, it is shown that the concept of a medium, apreferred frame of reference, is compatible not only with mediumtransformation, but also with Lorentz transformation and with theory of specialrelativity, so it is quite possible now to consider a realistic medium.Finally, a discrepancy is exposed within theory of special relativity, givingrise to assume a preferred frame of reference even in special relativity.
