Main Question or Discussion Point

in another forum a person said that the gravity moves off as an object.
i seid that is no true
the dialog has been longer but i can't traslate it all
what do you think?
could it be?
thank you for answers

... the gravity moves off as an object.
This doesn't make sense. You have a language problem. Try to rephrase the question.

I don't understand it either. Can you give an example of it?

Maybe matteo16's question is related to the one asked about how gravity "escapes" black holes on this thread?

You are likely looking at Mis-Understandings of various Interpretations of QM or particle physics attempting to describe what gravity is. Usually dealing with Graviton particles while some Interpretations add “Higgs particles”, neither of which have been ‘seen’ or verified experimentally (and per a strict view or General Relativity probably should not exist at all).

Cannot tell from your question if the debate you refer to might be:
1) graviton particles as they “move off” a chunk of mass.
OR
2) graviton particles that “move off” our world of existence in to other worlds of in a MWI view of total reality to account for why gravity appears as such a weak force in our world. (weak here because we lose many of the expected gravitons to other dimensions as they “move off”)
OR something else …

Doesn’t really matter: The point is, you cannot say that these interpretations are wrong or right without experimental proof or some real evidence one way or the other.
That is why they are interpretations not Laws of Physics.
No one has proof they are right and at least some interpretations remain that have not been demonstrated to be wrong.

But it does mean many interpretations are ignored, when working a different interpretation incompatible with them.

i'm sorry for the language problem(i'm italian)
i mean that this person said that the gravity isn't a force caused by the space-time curvature but that it moves itself.

You are addressing the incompatibility between General Relativity (Astrophysics) and Particle Physics (QM).
Science in a broad way divides between those two major theories:
If you wish to accept that there are gravitons you will likely be a Particle Physicist using QM and one of its many interpretations (oQM, CI, BM, MWI etc.)
If you instead choose to believe that there are no gravitons and gravity is accounted for by curvatures defined in GR; you will likely be an Astrophysicist.

Both branches can demonstrate that their approach is “accurate”.
Neither can proof the other approach is “wrong”.
So do not expect a clear answer as to which approach is “the correct” description of reality.

Obviously only one view can truly be correct.
But until someone can explain reality in a way that reconciles the incompatibility of these two major theories, we have to be willing to accept the use of two types of science with differing interpretations of reality when it come to describing how gravity works.
