Of course it can, just as is the case for electromagnetic waves, in fact, for any energy density. The RHS of Einstein's equations is the energy-momentum tensor of matter-multiplied by the coupling constant of matter to gravity, which is Newton's constant.

We know now, for certain, there is no .

Einstein and cotemporaries, used the classical addition of velocities (c + v) and (c - v) to deduce the underpinning of both Special and General Relativity : the purported "Relativity of Simultaneity" ---in error.

This is proved above and below.

Because there is no "Relativity of Simultaneity" there is no new time concept, and so we are left with an Absolute character to space and time, as described by Newton in his General Scholium.

The theory of general relativity is essentially defined by the energy density U(x,y,z,t) and the four-dimensional unitary space xyzt, in two distinct ways:

1- The geometric space xyz is infinite, and time t is integrated into it as a continuous spatial variable.

This is Einstein's classical theory of relativity from 1915, which we consider incomplete and sometimes misleading.

2- The modern theory of general relativity proposed by the author in 2020, which is more precise and complete.

In any case, the theory of general relativity is defined by the following matrix/tensor equation:

[The proposed theory induces Einstein's general relativity in a single sentence. In the matrix/tensor formulation],

∇2xx ∇2xy ∇2xz ∇2xt

∇2yx ∇2yy ∇2yz ∇2yt

∇2zx ∇2zy ∇2zz ∇2zt

∇2tx ∇2ty ∇2tz ∇2tt

What is the energy density of space-time!

where C is the curvature of geometric spacetime.

Einstein's fatal error was to invert equation 1, a flawed process that asserts that curvature creates gravity and not the other way around.

Equation 1 shows how and why the energy field of sound waves cause space-time to bend in a similar way to general relativity.

The Hidden and Little-Known History of Physics and Mathematics:

1- The universal law of physics:

U(x,y,z,t+dt)=B. U(x,y,z,t) . . . . (1)

in a control volume bounded by Dirichlet boundary conditions is rarely mentioned.

where B is the well-defined transition matrix and U(x,y,z,t) the energy density vector field.

Note that the quantum theory of transition matrices Q is intrinsically included in Equation 1 by simple substitution Q=SQRT(B).

2- It can be argued that Universal Law 1 is not only extremely important, but that it is the only universal law.

In other words, any other universal law can be derived from Equation 1, or be a subset of it. 3- Consider the intensity of the sound field and its reverberation time:

TR = 4 V / 6 A S C. . . (2)

Derived experimentally by W. Sabin a hundred years ago.

No physicist or mathematician has dared to address equation 2 in the last hundred years, and will not be able to do so in the next hundred years, simply because it is a universal law of physics or a subset of equation 1.

3- The solution found for the first time from equation 1 follows simply from:

∇2xx ∇2xy ∇2xz ∇2xt

∇2yx ∇2yy ∇2yz ∇2yt

∇2zx ∇2zy ∇2zz ∇2zt

∇2tx ∇2ty ∇2tz ∇2tt

Cxx Cxy Cxz Czt

Cyx Cyy Cyz C yt

Czx Czy Czz C zt

Ctx Cty Ctz C tt

= I(unit matrix)

where C is the curvature of geometric space.

The last equation is itself the Einstein curvature equation of general relativity.

A. Einstein loved the complications we call ugly mathematics.

The Einstein tensor [(Gµν) describes the curvature of spacetime in general relativity. It is a mathematical object that relates the geometry of spacetime to the distribution of matter and energy within it.]

Our goal, as the Q&A session indicates, is to find a physical description equivalent to Einstein's general relativity using cutting-edge physics.

The little-known and rarely mentioned genius Wallace Sabine was a professor of mathematical physics at Harvard and, in between, a leading consultant on sound quality in the finest concert halls.

Let's return to W. Sabine, who experimentally demonstrated his famous law of reverberation time, or the mean time between two successive reflections, TR, in regularly shaped acoustic rooms:

TR = 4 V / 6 A S C. . . (1)

where C is the speed of sound, V the volume, A the internal surface area, and S the absorptivity (corresponding to the diffusivity) of the walls.

Since then, no physicist or mathematician has dared to address equation 1 in over a hundred years, and will not be able to do so in the next hundred years, simply because it is a universal law of physics or a subset of the Cairo techniques. We can now theoretically prove Sabine's formula from the statistical theory of Cairo techniques, in the same way that we proved Einstein's classical general relativity in 1915, namely:

Note that any universal law can be deduced from the statistical theory of Cairo techniques or be a subset of it, simply because it is the theory of everything.
