In the first part of this book, the author synthesizes the main results and formulas of physics–Albert Einstein’s, with general relativity, gravitational waves involving elastic deformable space-time, quantum field theory, Heisenberg’s principle, and Casimir’s force implying that a vacuum is not nothingness. In the second part, based on these scientific facts, the author re-studies the fundamental equation of general relativity in a weak gravitational field by unifying it with the theory of elasticity. He considers the Ligo and Virgo interferometers as strain gauges. It follows from this approach that the gravitational constant G, Einstein’s constant κ, can be expressed as a function of the physical, mechanical and elastic characteristics of space-time. He overlaps these results and in particular Young’s modulus of space-time, with publications obtained by renowned scientists. By imposing to satisfy the set of universal constants G, c, κ, ħ and by taking into account the vacuum data, he proposes a new quantum expression of G which is still compatible with existing serious publications. It appears that time becomes the lapse of time necessary to transmit information from one elastic sheet of space to another. Time also becomes elastic. Thus, space becomes an elastic material, with a particle size of the order of the Planck scale, a new deformable ether, therefore different from the non-existent luminiferous ether. Finally, in the third part, in appendices, the author demonstrates the fundamentals of general relativity, cosmology and the theory of elasticity

“It is absolutely possible that beyond what our senses perceive, unsuspected worlds
are hidden” – Albert Einstein. And if on this point, Einstein was still right. Indeed,
when we look at photos of galaxies (see figures 1a and 1b), a vortex formed on the
sea (see figures 2a and 2b) or a photo taken of a vortex at sea during the tsunami
that occurred after the earthquake of March 11, 2011 in Japan or a hurricane on
earth (see figures 3a and 3b), how not to be struck by the similarityof spiral shapes
and textures, despite the difference in environment (respectively, space vacuum,
water and air)! In all cases, these spiral structures seem to bathe in a more or less
visible fluid, a sort of elastic continuous medium {171, 172}.
Just as the vortex in sea water is carried by a fluid filling all the space, or the
clouds of the hurricane carried by the Earth’s atmosphere, is not the cosmos also
made up of a substance invisible to our eyes and to our technology today in which
galaxies are immersed (see figures 1a and 1b) Indeed, it is well known that
astronauts train in swimming pools to simulate the behavior in weightlessness, a proof
thatinspacewefeellikefloatinginafluid.Theanalogyoftheequationsbetweenthe
gravitomagnetism (Lense-Thirring effect), the electromagnetism (dipole moment
effect), the fluid mechanics (rotational fluid dragging a solid sphere immersed in
fluid) is also interesting (see Wikipedia GravitoElectroMagnetism). In addition, we
only know5%oftheuniversethatconstitutes visible matter. What istheremaining
95% made of? Dark matter or dark energy?
In addition, the eye of the hurricane and the vortex in the spiraling water are
undoubtedly reminiscent of the supermassive black hole located at the center of each
galaxy.

VI Preamble
This is the initial idea and the common thread that guided me (see appendix A)
in an analysis of general relativity from the angle of the continuum mechanics
{1–17} and {57}at{59}. This led me to an extraordinary discovery concerning
the gravitational constant G and finally to the publication of a scientific article in
1,2the peer-reviewed physics journal Pramana published on August 13, 2020 by the
Indian Academy of Sciences.
Albert Einstein dared to question the Great Isaac Newton based on proven
physical and logical facts. Gravity is not instantaneous and bends light in a
deformable space-time contrary towhat Newtonthought in his time. I did the same
by pushing Einstein’s idea of the deformability of space-time to the end, that is to
say of associating the geometric deformation of space-time with a real deformable
elastic medium and study its properties according to the principles of elasticity
theorybycomparingthemtowhatisobserved(curvatureofstarlightbeamnearthe
sun, torsional deformation of space around the earth in rotation, generalized
swelling of space since the Big Bang, and deformation of space during the passage of a
gravitational wave). To say that the geometry of space is deformed under the effect
of the masses-energies present within it is good, to discover the mechanical
propertiesoftheassociatedelasticphysicalobjectwhichisdeformedisbetter!Especially
since the space is supposed to be empty, of classical matter, but could well be filled
with anunknown matter which escapes us until now. The quantumvacuum is there
to remind us. Emptiness is not nothingness. We can quote Casimir’s force joining
two plates in a vacuum resulting from quantum field theory which has been
measured and verified. The Higgs scalar field and its boson {124–129} which reappear

The search for truth is arduous, the road to it is fraughtwith pitfalls, to find the truth, it is
necessary to leave aside one’s opinions and not to trust the writings of the elders. You must
question them and submit each of their statements to your critical mind. Rely only on logic
