While this paper contributes to the understanding of general relativity, it’s essential to consider its context and relevance to your specific research on gravity and inertia. Remember that scientific discussions often involve multiple perspectives and ongoing research and it is better to cross-reference it with other relevant literature to form a well-rounded understanding.
- the linked article is on German, and so rather essential problems appear at attempts to comment it really rationally; however the thread topic “Gravity and Inertia” itself is quite really interesting and fundamental; and so should be commented.
For that it is necessary before to understand – what are “Gravity” and “Inertia”, what is possible only in framework of the Shevchenko-Tokarevsky’s Planck scale informational physical model, in this case it is enough to read
- where the absolutely fundamental phenomenon/notion “Inertia” is rigorously scientifically defined in first sections of the paper, the initial SS&VT Planck scale Gravity model is given in section 6. “Mediation of the fundamental forces in complex systems” [the model also is in the paper
More see the link(s) above, here only a few comments.
First of all, Gravity is fundamentally nothing else than some fundamental Nature force, and interactions between bodies in gravitationally coupled systems exist and happen because of action of this Force, and fundamentally that aren’t interactions in systems “mass-spacetime-mass”, what is fundamentally only illusory postulated in the GR. So, since the article in the thread preface is based on the GR, really that would have only a historical interest.
Gravity Force acts so that gravitational charges “gravitational masses”
[as that happens at actions of all other fundamental Weak, Electric, and Strong/Nuclear, Forces, when corresponding the particles’, bodies’… Forces’ charges constantly and always radiate the Forces’ mediators]
– constantly and always radiate Gravity Force mediators, which, if very specifically [how? – see the link above] hit into other body’s Gravity charge, cause releasing in the “irradiated” body.. of some energy/momentum, and so the irradiated body, say, moves with an acceleration, say, when freely falls toward a large radiating body.
Really mediators of all Forces in all non-exotic cases are radiated only by particles of bodies; the flows of mediators are observed in mainstream physics as Forces’ , including Gravity, fields.
In the mainstream physics the fields contain/carry some energy, which is transmitted to “irradiated” particles, bodies, etc., what is fundamentally wrong since that violates energy conservation law – this law holds only in the model above.
.
Gravity fundamentally differs from all other Forces in that all/every particles, and so bodies, stars, etc., have gravitational charges, while different particles have different sets other Forces charges; it is fundamentally universal Force.
Other fundamental difference Gravity from other Forces is in that all particles [which are close-loop algorithms, that run on Planck scale FLE “hardware”, more see the link above] have fixed part of their algorithms – at statics only one marked by Gravity FLE, while other Forces are “written” in tens orders by magnitude numbers of marked FLEs,
- while the algorithms run with frequencies ω=mc2/ћ, m is inertial mass, ћ is the fundamental elementary physical action/angular momentum Planck constant.
Since, again, that Gravity FLE is the same [one at 3D space rest]in all particles algorithms, the Gravity strength of a particle is proportional to the same frequency ω, as m is propositional;
- so, despite that Gravity and Inertia are fundamentally different attributes of particles, etc., gravitational charge/gravitational mass of a particle, etc., at least at statics is proportional to inertial mass. At application of corresponding coefficient it is possible – as that Newton had did – to postulate that gravitational and inertial masses are equal.
