*But GR is not derived from Newtonian gravitation but even if it were*Are you scientifically illiterate?

Here is the reference which derives DIRECTLY in a straightforward manner Einstein's gravitational field equation from Newton's ATTRACTIVE GRAVITATION MODEL.

https://arxiv.org/pdf/1309.4789.pdfFrom Newton’s Universal Gravitation to Einstein’s Geometric Theory of Gravity

From the very start, section 2, the authors indicate and do mention that NEWTON'S APPROACH IS BASED TOTALLY ON THE ATTRACTIVE LAW OF GRAVITATION.

"Newton’s universal law of gravity[1] states that the

**attractive** force F

_{01}(x

_{0})..."

*does not claim that gravitation is an attractive force.*

Gravitation under GR causes an inertial force just as centripetal acceleration causes an inertial force.General relativity HAS NO MECHANISM WHATSOEVER TO DESCRIBE GRAVITY.

General Relativity postulates that gravity is a curvature of spacetime created by mass, but it does not explain how that curvature occurs. Actually, it is just a DESCRIPTION that leaves unanswered the key question of exactly how matter affects space and time.

Dr. Erik Verlinde:

General Relativity remains just a description of the force we call gravity. It leaves unanswered the key question of exactly how matter affects space and time.

General Relativity HAS TO rely totally on Newton's ATTRACTIVE MODEL.

This is what you wrote earlier:

*The huge mass of the Earth bends spacetime*Explain to your readers HOW mass bends spacetime. You haven't done so at all.

No one else can explain how mass/matter interacts with spacetime, not even Einstein.

**Einstein could not explain how mass warps space.** What's worse is that with the advent of the Aharonov-Bohm effect (electromagnetic and gravitational) physicists found out that Einstein's general relativity is incomplete, since it cannot detect the gravitational potential:

G. 't Hooft discovered that "by using light rays alone, one cannot detect the scalar component of the energy-momentum tensor":

https://arxiv.org/pdf/1410.6675.pdf**Feynman resolved the energy-momentum tensor problem by the field approach: the gravity force between Newton's apple and the Earth is caused by the exchange of gravitons. Gravitons (real and virtual) are mediators of the gravitational interaction.**Then, you have a huge problem: how do gravitons produce curvature?

Again, general relativity DOES NOT offer any kind of a mechanism.

That is why physicists have to rely on Newton's attractive gravitational model.

Exactly proven in this paper.

Einstein's gravitational field equation is derived directly from the attractive gravitation equation of Newton.

From the very start, section 2, the authors indicate and do mention that NEWTON'S APPROACH IS BASED TOTALLY ON THE ATTRACTIVE LAW OF GRAVITATION.

"In this paper Einstein’s gravitational field equation is obtained from a step-by-step generalization of Newtonian gravitation.

We thus obtain a single component of Einstein’s gravitational field equation in local coordinates. From the principle of general covariance applied to a single component, we obtain all tensor components of Einstein’s gravitational field equation.

The result is Einstein’s equation for the gravitational field."

EINSTEIN'S GRAVITATIONAL FIELD EQUATION OBTAINED DIRECTLY FROM NEWTON'S ATTRACTIVE LAW OF GRAVITY.

"In most presentations of Einstein’s general theory of relativity[8] his gravitational field equation is given in tensor form as embodying some general principles.

It is then shown that in the limit of weak gravity and small speeds it reduces to Newtonian gravity.[9, 10, 11, 12] This top-down approach makes it difficult for the student to understand the gravitational field equation. In this paper we use a bottom-up approach to obtain Einstein’s field equation from Newton’s universal gravitation."

Conclusion: the RE have no idea whatsoever how four trillion billion liters of water stay in place next to the outer surface of a sphere.
