Abstract

In this comunicationone starts by analyzing the actual justification of the separation existing between electrical and gravitational forces. The existing justification is that for neutral bodies the electrical dipole interaction force at long distances r, totally cancels as equal and opposed forces given by Coulomb law. It is emphasized that the interactions at short distances including van der Waals forces, are also based also on actual Coulomb law. Moreover was demonstrated in the paper, that the type of the force between two dipoles with the same orientation - attraction or repulsion- is given by the variation mode of the force with the r distance, being always attraction force in the case of the decreasing force with distance (exponent n≥1, for 1/rn), and always being repulsion in the contrary case. In the paper one demonstrates that this electrical dipole force may exist at any distance, but it depends on a term in 1/r4 or greater power, being negligible compared to the gravitational force, which depends on 1/r2. As well in order to obtain the principal term in 1/r2, for electrical dipole interaction, it was necessary and sufficiently to admit a hypothesis which considers the Coulomb laws a series of terms of powers of r, including a new term of the form –ln r. With this corrected Coulomb law, for dipole interaction force, an expression having the principal term in 1/r2 results, as in the gravitation force law. In order to verify the above hypothesis, numerical checking was made utilizing actual electric permeability, the constant ε0. These calculations made for an astronomical distance, showed a good agreement (relative ratio R≈2,5) between the force given by Newton’s law and the force obtained with the corrected Coulomb law. The best agreement is obtained when the polarization of all nucleons including the neutrons is considered (R≈0,62). On the basis and findings of this gravity theory, some important consequences and conclusions result [1]. The electromagnetic interactions based on the corrected Coulomb’s law are the only necessary and sufficiently to yield all of the four known forces in nature, so unifying them. In the future, the actual Coulomb’s law must be experimentally verified at great distances when some correction and new constants, probably will be necessary. The actual Newton’s law looses its object together with the attempts and experiments aiming to detect the gravitational waves. The simultaneous and multi-direction interactions between dipoles, supposed by our theory are physically possible only in quantum manifestation of the charges, and admitting the presence of a continuum media (as a modern ether) as absolute support of electromagnetic interactions. As a consequence, this continuum media must yield the inutility of special relativity theory principles, as is argued by our new interpretation of Michelson experiment which contradicts the classical interpretation [2]. In the general relativity theory, the so called space/time entity and his gravitational curvature will lose their starting basis, the actual gravitational forces. In astrophysics the so called black holes, loose their theoretical basis and iIn cosmology the so –called big- bang, loose its theoretical basis. References: 1.

Abstract

In this paper we have reanalyzed the classical hypotheses and the theoretical basis of Michelson’s interferometer experiment. Initially, the reanalysis of the illustrative model of the interferometer, represented by a boat traversing a river, reveals that the correct transversal trajectory is not an isosceles triangle as classically thought. Similarly, the transversal light path in the interferometer, considering the Huygens-Fresnel theory of light with the correct reflection/returning angles and taking into account the supposed ether presence, was found to be different from that supposed by Michelson. A correct alternative light path, as a rectangular triangle instead the isosceles triangle for transversal path, was found. For the new light path resulted zero or negligible time difference, compared to that expected theoretically by Michelson, and in accordance with some very small time differences, reported in many experiments including Michelson’s own experiments. Thus the second order effects indicated by Maxwell exist, but do not depend on the light path direction and consequently Michelson device is not appropriate for their measurement. For the Michelson proposed purpose, two time measurements for each direction are necessary. The above findings [1] may also be applicable to other similar experiments with light or with other electromagnetic waves (lasers, masers, X rays, γ rays, etc.). Consequently, Michelson’s interferometer experiments should not be considered negative concerning the presence of the ether and can not be anymore considered a base for Einstein’s Special Relativity Theory (SRT). The ether presence and the SRT from 1905 must be reconsidered,with important predictable consequences upon the actual physics. References: 1. Ioan Has, Simona Miclaus, Aurelian Has.
