The Interpretation of Inertial Force and The Existence of Absolute Background

The formalism of classical particle dynamics is reinvestigated according to the basic requirement of causal consistency, and a new equation of particle dynamics, which is more general and more in line with classical mechanics experiments than Newton's second law, is obtained. More importantly, the inertial frame of reference is no longer required and the inertial force is no longer introduced by hand. The new dynamical equation can be straightforwardly applied in any reference frame as long as which is irrotational with respect to the absolute background of the universe. The nature of the inertial force is nothing but the real forces acting on the reference object. The essence of this reform of classical particle dynamics is just a drawback of traditional formalism in Newtonian mechanics being corrected. However, it may be more important that a logical derivation of this new particle dynamics equation strongly suggests the existence of an absolute background for the whole space of the universe. In physical concepts, the absolute background for space does not conflict with the relative length of the base unit of space in Einstein's Special Relativity and General Relativity. Furthermore, the size of the base unit of space should essentially be understood as the length of the line segment, which is cut from the absolute background of space by the intrinsic physical events.

Relativistic Spacetime Based on Absolute Background

Based on the consideration of naturalness and physical facts in Einstein's theories of relativity, a nontrivial spacetime physical picture, which has a slight difference from the standard one, is introduced by making a further distinction on the absolute background of spacetime and the relative length or duration of base units of spacetime. In this picture, the coordinate base units in gravity-induced spacetime metric are defined by the standard clock and ruler equipped by the observer, and duplicated onto the every position of the whole universe. In contrast, the local intrinsic base units of spacetime in gravitational field are defined by the length and duration of physical events intervals in the same-type standard clock and ruler which are really located at every position of the universe. In principle, the reading number of the standard clock is counted by the undergone times of unit intervals defined depending on a certain kind of local intrinsic events. But the size of the base units of spacetime is essentially depicted by the length of the line segment, which is cut from the absolute background of spacetime by the local intrinsic events of unit interval. The effect of gravitation is just to change the length of this segment for base spacetime units. On the basis of such a physical picture of spacetime, in a fairly natural way we re-derive a new classical dynamical equation which satisfies a more realistic and moderately general principle of relativity. To further examine this physical picture including of gravitation and spacetime, we also reinterpret the gravitational redshifts for solar gravity tests.

Mass Operator and Gauge Field Theory with Five-variable Field Functions

To investigate the mass generating problem without Higgs mechanism we present a model in which a new scalar gauge coupling is naturally introduced. Because of the existence of production and annihilation for particles in quantum field theory, we extend the number of independent variables from conventional four space-time dimensions to five ones in order to describe all degrees of freedom for field functions while the conventional space-time is still retained to be the background. The potential fifth variable is nothing but the proper time of particles. In response, a mass operator $(\hat{m}=-i\hbar \frac{\partial}{\partialτ})$ should be introduced. After that, the lagrangian for free fermion fields in terms of five independent variables and mass operator is written down. By applying the gauge principle, three kinds of vector gauge couplings and one kind of scalar gauge coupling are naturally introduced. In the current scenario, the mass spectrum for all fundamental particles is accounted for in principle by solving the eigenvalue of mass operator under the function of all kinds of interactions. Moreover, there no any auxiliary mechanism including spontaneous symmetry breaking get involved in the model. Therefore, traditional problems in the standard model such as the vacuum energy problem are removed from our model, as well as the hierarchy problem on the mass spectrum for fundamental particles.

From the revelation of the nature of inertial forces to questioning the proposition of dark energy

Starting from the revelation of the nature of inertial forces, this article discusses the subdivision of the basic physical concept of space-time and raises questions about the metric of standard cosmology. A new form of particle dynamics equation which is strictly applicable to any translational reference frame is rigorously derived within the framework of Newtonian dynamics. This necessary brings three important implications. Firstly, a comprehensive and detailed derivation of the generalized dynamics equation strongly suggests that the fundamental concept of space-time in physics should distinguish between the absolute background of space-time and the relative inherent units of space-time. Secondly, the inertial force is successfully revealed as the real force acting on the reference object, which directly conflicts with Einstein's strong equivalence principle. Thirdly, Einstein's idea in general relativity to eliminate the dependence on inertial reference frames loses logical support. Based on these new physics and results, a properly adjusted physical picture of space-time is introduced. In this spirit, the gravitational redshift effect in the Schwarzschild metric is also successfully re-interpreted. Correspondingly, the FRWL standard cosmological metric is necessary modified. A new factor $b(t)$ must be introduced into the time term $dt$ to represent the time dilation effect caused by the increase in the potential energy of cosmic average gravitation on the longitudinal direction of time. Qualitative analysis indicates that the proposition of dark energy can be alleviated, and at the very least, a re-analysis should be conducted based on the proposed new cosmological metric.
