Relativity predicts a variable G. The full demonstration is given below.

(The above version is the latest; an archive version might be older). The proof starts by considering a dimensionless particle in an empty universe. Then two particles, three particles, and an infinite set of particles are studied. This allows to calculate space-time structure for any realistic energy distribution. The proof uses the interchange of limits theorem, and ad hoc sequences of energy distributions. With only one particle the result is a singularity everywhere if the universe is empty outside of the particle. Those singularities disappear completely with three particles. Then this calculation is done for any realistic energy distribution. An equation of G is given naturally in the process. This equation is a correct approximation in most of the cases. The fundamental principles building Einstein equation are still valid, but now the constant anthropocentric solar system value is shown to be weaker in strong matter density environments, and greater in low matter density environments. Hence the surrounding effect arises. And surrounding is the simplest gravitational model based on this effect. It means that with this corrected relativity, the gravitational mysteries of today simply do not exist. In other words, today the calculations of the gravitational predictions of relativity are wrong. And when this error is fixed then it remains no gravitational mysteries anymore.

How does this surrounding effect arise in relativity? Well, the main involved mechanism can be understood by a thought experiment. Let's imagine a sole wave propagating. Let's call this wave the "A" wave. And the universe is full of such waves, generated by the quasi relativistic quarks. If matter density of the universe is weak, each time A will encounter another wave (generated by a quark), it will not modify much the space-time deformation which is generated by A. But if matter density of the universe is strong, then there will be more of those encounters, and also the other waves encountering A will get a stronger energy. Those other waves will add also their strong contributions to the final space-time deformation. Therefore the relative contribution of A to this final deformation will be weaker. And finally the final space-time deformation generated by A will be weaker. This retrieves the surrounding effect.

If Einstein equation is wrong, what is (or are) the new equations ?

Einstein equation is still correct, must be applied with a variable G. The fundamental equation of General Relativity is given by Lagrangian in vacuum. And this is the only fundamental one. From this Lagrangian equation in vacuum, taking into account equivalence between ad hoc energy distributions, an equation is constructed naturally, which yields the four-vectors describing locally space-time structure. I uses the four-vectors of the gravitational waves which are generated by the ad hoc equivalence energy distributions:

This equation follows the rule of the surrounding effect, which then arises in relativity. Also an equation of G can be given, which is a good approximation in most of the cases.

In this formulation it is only a (good) approximation. Its possible divergence is fixed the same way as the Olbers paradox is fixed. There is also a cutting-off value of 15 kpc for the interaction distance which is seen in the galaxy simulations. The square root over the energy of the relativistic or quasi-relativistic particles appears to be wired at first glance. But the so-called four-momentums of equation (1) giving rise to this equation of G are not four-momentums but simply four-vectors of contributions allowing to calculate space-time structure. 

As a result, Einstein equation can still be used in most of the cases, that is, in the cases where the surrounding value is constant. But it must use the recalculated value of G given by this approximated equation. In more complicated cases, the only valid equation is conservation of Lagrangian in vacuum.

G constant measurements

The measurements of this "constant" are extremely inaccurate and are even contradicting themselves. 

This is a prediction of relativity. Even surrounding predicts different measured values of G depending of the astrophysical context.

In reality there might exist shielding mechanisms involved. It means that the denominator of the equation of G above must be corrected by insertion of an attenuation factor in the terms of the sum. There is a clue for that shielding to occur, with the existence of the two values of the "alpha" parameter of surrounding. Also there are clues to think that this phenomenon might be correlated to the Casimir effect. And this would not contradict the today's explanation of the Casimir effect, which is done with quantum mechanics. 

For confirmation of this, a test is to measure G, successively, 2 times. For the first measurement the apparatus is located in the middle of a metal box. For the second measurement the box is taken out. If possible, metal walls are inserted between the attracted object and the attracting object, in a symmetrical way, that is, another similar wall is located on the opposite side with respect to the attracted object, at the same distance of the attracted object. The first measured value is predicted to be greater than the second one.

For the full understanding of this shielding effect, the following fractional formulation of equation (1) must be used, in place of the equation of G.

The first measurement decreases the denominator. The second one increases it. And if the two walls are inserted during this second measurement, it decreases the numerator.

Looking forward for help

I need help for the realization of the G constant measurement (described above).
