Comparing gravitational field to electromagnetic field, the charge has the same sex and the opposite sex, but there are two kinds of "force"? Is there any gravity and any repulsion? What if Newton's second law was the repulsive force?
Preprint The system of gravitational field equations
Dear Duan Xian Xiang ,
When my daughter was just over 1.5 or 2 years old, I asked her why the ping pong ball falls when I let go free?
Her answer was simple: 'the ping pong ball falls because there is nothing under it.'
I knew right then that my daughter had an excellent response!
Planet-erosion was formulated in 2007:
http://planeterosion.blogspot.com/
There is no theory of gravity that allows this!
Interestingly, I didn't have the theory of gravity that would allow this objective phenomenon either!
It was born two years later:
Tényekkel igazolható a gravitáció valós oka (The gravity can be reasoned with fact) (Hungarian)
Article Tényekkel igazolható a gravitáció valós oka
(If you need it, exists its English version)
The article was rewritten with an American co-author who thought I had stolen his idea in 2008:
Article Gravity a paradym shift in reasoning
Even so, his name is in the reference, because it was thanks to him that I accepted the idea that I got intuitively. Our idea was very similar.
When I realized that it is possible with this theory to prove the existence of gravitational waves in an easy way, as well as the existence of the graviton... It was necessary to write a new article.
It was ready in two months, but I accidentally deleted it, so it was lost.
After that, it was very difficult to finish. It took over 18 months to complete.
I formulated it much more thoroughly than the first version. An ontological concept, a prori entity has been introduced. And now the new version has been created, and with it I have succeeded to confirm what my daughter said:
Article Fizikailag-metafizikailag bizonyítható a graviton létezése
My co-author of the article: 'Gravity a paradym shift in reasoning'
said the next onto the base of conclushion:
Chapter Physico-metaphysical proof of the existence of graviton
'’No quark
No, contradict you!
Our theory extended
It has Newton and Einstein too..’
Conclushion:
The gravity has no repulsive force: gravity is dependent on electromagnetic matter structure: which in the mentioned article has been named: a priori entity.
Regards,
P,S: The apriory entity is coform to the yin-yang principle!
The short answer is No. Coulomb's law is the non-relativistic limit of the interaction between two electric charges and the invariance of Maxwell's equations under linear transformations that mix electric and magnetic field imply the existence of charges of either sign, that compose upon addition.
Newton's law is the non-relativistic limit of the interaction beteeen two masses, only the corresponding invariance of Einstein's equations is different. In particular, since gravity is transmitted by a particle of spin 2, it's always attractive.
Earth's gravity is working under temperature, pressure, and mass of object , not Newtonian weight or force of 9.81.

My "repulsive force" is not "antigravity," I mean, gravity is attraction, but Newton's second law is "pushed force," so I think if gravitation is to be combined with the second law, you need to add a negative sign to the second law.
Stam Nicolis
This has a lot of significance, Oliver Heaviside's gravity magnetic equation Lead to contradictions，because of this negative sign, and now there is no contradiction. Oliver Heaviside The man who simplified Maxwell's equations. His gravitational equations could explain gravity, but it have useless because of the negative sign in it, and now it's changed.
Stam Nicolis
Einstein's field equations are very similar to Oliver Heaviside's equations, but actually, I suspect that he is based on Oliver Heaviside's equations. So, once the contradiction of Oliver Heaviside's equations is eliminated, it may replace relativity.
The relative signs in Maxwell's equations are fixed by Lorentz invariance and gauge invariance and these symmetries imply that electric charges are additive.
Replacing in Maxwell's equations-written in covariant form-the flat, Minkowski, metric by a general metric, leads to Maxell's equations in curved spacetime. Writing the curved space metric as the sum of the flat metric and a ``perturbation" leads to Maxwell's equations in a medium. All this wasn't clear in Heaviside's time, it is, now.
Stam Nicolis
Do you mean, even if Oliver Heaviside's equations eliminate the contradiction, it still can't solve the problem of relativity? Because the form of Maxwell's equations is imperfect?
There isn't any problem of relativity with Maxwell's equations: They're uniquely determined by Lorentz invariance (which means relatitivity), gauge invariance and the requirement that they contain no more than two derivatives. This is a standard exercise in electrodynamics.
It would be useful to start reading textbooks that don't date from the 19th century.
Stam Nicolis
I added the speed parameter to the Maxwell equations because it has no medium reference frame. I deny relativity on the basis.
Stam Nicolis
I know that Maxwell's equations and relativity are natural harmony, so I started with modifying Maxwell's equations, and I think it is really missing something, missing the medium reference frame.
Stam Nicolis
Because Maxwell's equations lack a frame of reference, some paradoxes arise, and relativity arises to solve them. So, the problem starts with Maxwell's equations.
No paradoxes arise. It would be a good idea to learn classical electrodynamics, before making trivially wrong statements.
Stam Nicolis
The motion-induced electromotive force of the Lorentz force produces a paradox because there is no frame of reference. Relativity says that "the electric field force and the magnetic field force cancel each other out", which is the content of the electrodynamics textbook
Stam Nicolis
Faraday's law is also paradoxical, because the magnet and coil motion is different and the emergence of magnetic field or electric field contradiction, relativity said "electric field and magnetic field are different effects of different reference frame", these are paradoxes, because of the lack of reference frame. The first reason for Einstein's theory of relativity was to solve the paradox of electromagnetism.
No it isn't. This is all part of any undergraduate physics curriculum, so it's useful to stop pretending to live in the past.
Taking the equivalence principle at face value at the large scale, acceleration (of the universe) is equal to (repulsive) gravity. Then gravity can be seen as only apparently attractive at the smaller scales. Preprint Particles from Gravity (Jul 24, 2021)
If the speed of gravitational signalling is finite, our perception of the position of a moving star will always be out of date. We'll see and feel the star to be further back along its path than it actually is.
- So if the star approaches we'll feel its gravitational field corresponding to a more distant location, and the star's pull will be weaker.
- If the star recedes, we'll feel a pull corresponding to the star's effect when it was nearer, and the star's pull will be stronger.
This weakening and strengthening effect can be abstracted out as a separate field component, (the star's polarised gravitomagnetic field component) which corresponds to a positive (attractive) gravitational field for recession and a negative (repulsive) gravitational field for approach.
When bodies couple via their gravitomagnetic fields, we can get momentum exchange, and the slingshot effect.
When a star or planet rotates, the gravitomagnetically increased pull of its receding side as compared to the gravitomagnetically reduced pull of its approaching side causes matter and light to be dragged around with it, to some extent. This rotational dragging ("frame-dragging") effect is necessary for implementing the relativity of rotation in a general theory of relativity. This is the rotational gravitomagnetic effect described by Einstein in 1921, and verified by the Gravity Probe B experiment.
When a body is forcibly accelerated, the higher-order version of the velocity-dependent gravitomagnetic effect gives an accelerative gravitomagnetic effect, that deflects light and matter in the body's direction of acceleration (accelerative induction, again described by Einstein in 1921).
Preprint Principles of Gravitomagnetism I - Unavoidability

In Newton's Opticks, gravity is interpreted as being the deflection of light and matter due to an aether-density gradient and a corresponding gradient in lightspeeds, the deflection being analogous to the deflection of light at an air-glass boundary (again, due to the density variation in the medium, and the associated variation in lightspeeds).
In Newton's system, a moving body would be represented as a moving aether-density feature, and as long as the speed of propagation of density waves in the medium was finite, we'd expect to see effects analogous to gravitomagnetic dragging.
Duan Xian Xiang , That's one way of describing it, yes. "Doppler mass shift" (instead of Doppler frequency shift).
