What is Space-Time Made of ?

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 ?, 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, ?, h
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.
