I proposed a theory where I derived an epoch-dependent Law of Gravitation. This and other measurements would collide with my theory.
My claim is that these analyses suffer from Confirmation Bias and are incorrect.
In simple terms, the Moon is receding with 4 cm/year and has an average orbit radius of 384,400,000 meters.
This means that
1/r*dr/dt=1.04E-10/yr
My theory predicts 1/G*dG/dt=c/R0=H0=0.74E-10/yr
where R0 is the 4D radius (13.58 GLY) of the Universe and H0=Hubble Constant of 72 km/s/mpc.
Leaving 41% of the observed receding velocity to be explained by tidal interactions, frame dragging and the use of incorrect Laws of Gravitation and Dynamics.
The Lunar Ranging results are equivalent to saying that we know the dynamics and can explain receding velocity with a 1:1000 precision. The effect of a variable G is supposed to be below 2E-13/year.
So, I think it is ludicrous and no conclusion about epoch-dependent G can be derived from this paper.
Later I will explain why this other article is wrong:
Constraining a possible variation of G with Type Ia supernovae

Dear Marco
simple observation
Article What is Gravity
orhttps://www.academia.edu/37525574/Quantum_Mechanic_Gravity
maybe help some of your view.
I know what Gravitation is.
I also know that people only have an empirical law (Newton's Law).
This work claims to constraint the effect from G to below 2E-13/year, while the receding velocity is 4 cm/year and the orbit has on average a radius of 384,400,000 meters.
This means that
1/r*dr/dt=1.04E-10/yr
So, this article claims to know from a failed empirical law of Gravitation, that the receding velocity is equal to 1040+-2 E-13
That is ludicrous.
With respect to your offer to teach what is gravity, thank you but I know what Gravity is.
Javad Fardaei
By the way, Javad. How do you know that you know something about Gravity if your article does not have a single equation?
Nasa made this same experiment on the surface of the moon by releasing a feather and a hammer from the same height on the moon, both reached the surface of the moon at the same rate falling and hitting at the same time. Again, if there were any gravity force in the moon’s center, the heavier object should have reached the surface before the feather, based on the theory of more mass - more gravity or more density more gravity.
C'mon, Javad. "More mass, more gravity", "more density more gravity"
Again, if there were any gravity force in the moon’s center, the heavier object should have reached the surface before the feather, based on the theory of more mass - more gravity or more density more gravity.
This theory that you speak of was what people in Medieval ages use to think. It is totally wrong and we know that since Sir Isaac Newton!
