REALITY BEHIND RELATIVITY
Laws of nature is impartial in the physical universe therefore should remain invariant irrespective of domains for unity of universe. If the basic constituents of the universe and the universal norms of basic constituents are not properly understood then we would require special considerations in some situations to justify the dynamics. Special relativity is one of them. Anything special goes against the uniformity of nature. Hence special relativity is required to be understood in a normal manner without the increased relativistic mass. This author has developed the exact relativistic equation while keeping both mass and the laws of dynamics invariant. A proper understanding of extra nuclear space structure of particles and the structure of vacuum/ space-medium helps to understand the so-called relativistic dynamics in a natural manner. According to this author if all features of structure and dynamics in different domains are generalized, then automatically we arrive at universal nature of structure and dynamics of systems. The physical universe essentially consists of physical things. The basic constituents of the universe are mass & space and therefore, both mass and space are physical. All physical existences have shape and size hence geometry is applicable to both mass as well as space. Space is invisible therefore its physical nature is not easy to visualize however the physical features can be conceptualized from the physical features of matter (mass-space integral systems). We know the content of matter varies per unit volume thus mass-density can vary. In the same way more space can be compacted in a given volume or space can be rarefied while expanding to a larger volume. A given space can contain different space matter particles. Thus space pockets at different location may have different space density (space content per unit volume) as well as can contain different space matter particles. Hence qualitatively different space pockets are not same.
Space is not geometry but some describe space through geometry. Space being physical entity, geometry is applicable to it.
According to Newton space devoid of matter is free space or vacuum. He conceptualized space to be non-physical i.e. geometrical in nature and accommodation provider for matter. Subsequently the property of space was found to vary depending on its location in relation to matters in it background (celestial bodies). Einstein realised that the concept of uniform flow of time is not correct. According to Einstein each dynamic system has its own time and the dynamic space of universe having different dynamism at different space pockets have time varying property. A space pocket can be completely defined by 3-D geometry of space and the state of dynamism of space, gauged by time of the space pocket. Thus Einstein generalized the quality of space through the clubbed property of space-time. The physical nature of space was determined through 4-D space-time geometry. According to this author neither geometry nor time are physical entities hence the clubbed space-time is non-physical. To realize the physical nature of space, mathematicians conceptualized that each point in space is an assembly of mathematical objects and events. The mathematical objects and events are hypothetical. Their reality cannot be shown in terms of tangible physical objects. When mathematics itself is non-physical the mathematical objects and events have to be non-physical.
If space itself is not physical, no manmade mathematical technique can make space physical. According to this author it is absolutely necessary to conceptualize the physical space and its variation of parameters (properties) in relation to proximity of matters. The universe comprises mass and space as physical entities. There exists mass space attraction, space-space repulsion and mass-mass repulsion. Due to these instincts of mass and space every dense mass (matter) forms a space-structure surrounding the dense mass as nucleus. The space density (space content per unit volume) of extra-nuclear space structure is highest at the surface of the nucleus and lowest at the boundary of extra-nuclear space structure. And again the space structure contains space matter particles whose size and number density is a function of distance from the nucleus. The space structure also rotates along with the rotation of the nucleus as one integral body. Therefore the dynamism (velocity) of space pockets or otherwise expressed as time of space pockets is also a function of distance from nucleus. The mathematically conceptualized space time parameter is simply a description of physical space in terms of space density (space content per unit volume), quality and quantity of space-matter particles, velocity of space pocket, and the gradient of these parameters. The gradient decreases with the increase of distance from the nucleus so also the gravitational attraction. As such, Einstein could describe space-time curvature as the measure of gravity potential in space.
If an event is a function of many variables, mathematically the unknown parameter of the event can be evaluated from known parameters considered independently or by relationally clubbing some known parameters. If solution is feasible by clubbing space and time then the solution would also be possible without clubbing the parameters. The 4-D clubbed space-time geometry is beyond normal human perception. Therefore the parameters space and time need not be clubbed for solving the dynamics of matter in space. This author has given a clear picture of the qualities of space and significance of general relativity in this volume.
