In Search of Cracks in Albert Einstein’s Theory of Gravity

In Search of Cracks in Albert Einstein’s Theory of Gravity
---
"During a solar eclipse in 1919, Arthur Eddington observed light bending around the sun just as predicted
by general relativity, Albert Einstein’s new theory of gravity. Since then, general relativity, which says
that massive objects like stars warp the fabric of space-time ( the surface of cosmic vacuum warps /bends
near to qravity-stars and light changes its straight way near stars) around them, has passed increasingly
precise tests. A year rarely goes by without a new experiment or observation confirming
Einstein’s theory. But there’s a hitch. . . .
Why do you think we need to modify or extend gravity?
The problem is that general relativity is not general enough.
When do you expect observations will start to disagree with general relativity?

To describe Einstein's macro-gravity fully a fundamental, quantum theory of gravity is needed.

No matter how the theory of general relativity will expand,
it must work no worse than GRT and include all its phenomena.

GTR brings (adds) only a limited speed of gravitational propagation to Newton's gravity. It is necessary to realize that the Past is a different phase of space-time (it has a different structure) than the Future. The quantum "world" is to understand as the their phase interface / boundary. Dark matter is aether / just physical space and physicists have lost their good sense:)

Dark matter must exist in the cosmic vacuum. Dirac explained:
the cosmic "vacuum sea" is filled with dualistic "virtual" particles
E=±MC² (dark matter), which somehow can appear in
quantum fluctuations, Casimir effect, Lamb shift.

In quantum mechanics, it is difficult to talk about "virtual particles". The particle can be “measured” (fixed into / glued on the surface of the Past) or not. On the other hand, physical space (aether) aparently contains a certain (statistically) natural admixture of antimatter, which causes gravitational repulsion as a prevention of gravitational collapse of space itselve… Gravitational waves need gravitational attraction as well as repulsion…

This may be related with unlucky Einstein’s gravitational constant..

When do you expect observations will start to disagree with general relativity?

They already do.

Observations do not agree with GTR, because GRT is bad, it has to help itself with some kind of obscure dark matter.. Stars in galaxies move somewhat "viscous" and it GTR cannot describe… Something like gravitational “magnetism”, which mediates entrainment / pulling by the moving surrounding matter, needs to be added…

The observations are consistent with Einstein's general relativity:
gravitational masses (like our Sun) change the flat surface
of "absolute 4D space-time" in the local region,
and the direct path of light curves near gravitational masses (like our Sun).

I should have amplified my comment. My understanding from the literature is that relativity theory can't actually explain why there are galaxies, ie, why matter clumps (whether dark or baryonic). If the universe had continued to expand as an isotropic soup of particles, nothing in relativity theory would be contradicted. Additional hypotheses are required to explain the clumping. Or is that not the current understanding?
