Text Box: The world, modern physics tells us, can no longer be divided into matter and empty space.
The world is a single, seamless whole. …
In 1905 Albert Einstein brought the whole 2,400-year-old house down. In the introduction to his first paper on the special theory of relativity, which ushered in a revolution in physics, he declared simply that the ether hypothesis was "superfluous." To critics who might object that waves need a medium to carry them, he replied, in effect: That may be true for some waves, but for light it just doesn't happen to be so. Exit the ether.
The vacuum thus cleansed remained empty for a quarter of a century, but then it began to fill up again – this time with the conceptual fruits of quantum theory. Quantum mechanics was introduced in 1925 as a replacement for Newton's mechanics in the description of atomic phenomena such as emission and absorption of light. It turned out to have implications for the vacuum as well. ...

Text Box: The central failure of classical mechanics, it is often said, is its inability to account for the structure of the atom. 
That is, until now.
With increasing observations of the submicroscopic, it has now become only all too plain that:

 THE ATOM IS THE CONDENSED FORM OF MATTER, OR MASS-ENERGY, 
AND ELECTROMAGNETIC RADIATION THE EVAPORATED FORM.

And the vacuum being totally permeated and filled with the cosmic background radiation, or CBR,

OUR UNIVERSE OF OBSERVATION IS BUT A CONTINUUM IN MASS-ENERGY, VOIDLESS AND SEAMLESS IN ITS ENTIRETY.

This is the final perspective.
In it, all of fundamental physics becomes classical mechanical in scope and high-school stuff in comprehension.

Text Box: The 2.7K Background Radiation At wavelengths in the range of millimeters to centimeters, the extraterrestrial electromagnetic radiation background is dominated by an isotropic component, the cosmic background radiation, or CBR. The isotropy suggests the CBR is a sea of radiation that uniformly fills space. This would mean an observer in any other galaxy would see the same intensity of radiation, equally bright in all directions, consistent with the cosmological principle.”

Text Box: The space of mechanics is regarded as empty wherever there are no material bodies present. The space of optics is filled with ether. The ether is considered to be a kind of matter that has a certain mass, density, and elasticity. Accordingly we can immediately apply Newton's doctrine of space and time to the universe filled with ether. This universe then no longer consists of isolated masses that are separated by empty spaces but is completely filled with the thin but almost rigid mass of the ether in which the coarse masses of matter are floating. The ether and matter act on each other with mechanical forces and move according to Newtonian laws. Thus Newton's standpoint is logically applicable to optics. The question is only whether observation is in agreement with it...

Text Box: In physical reality, the long-sought ether is indeed the evaporated form of classical matter. 
And the space of mechanics and the space of optics unite in total and logical agreement with observations,
from the subatomic to the cosmic.

In hindsight, it seems hard to fathom that what should have been plainly obvious had escaped great minds of the caliber of Einstein, Bohr, Born, Michelson, Morley, Poincarι, Lorentz, and FitzGerald, to name but a few.
However, with contemporary Peebles, the first and authoritative step seems to have taken place in the right direction...
Text Box: Aether Drift: Observation Blackbody radiation can appear isotropic only in one frame of motion. An observer moving relative to this frame finds that the Doppler shift makes the radiation hotter than average in the direction of motion, cooler in the backward direction. That means the CBR [Cosmic Background Radiation] acts as an aether, giving a local definition for preferred motion.

Text Box: The Equivalence of Mass-Energy – the Final Perspective
Mass and energy are not only equivalent but the two are also inseparably embodied as one and the same 
physical entity – mass-energy – in the radiaton. (See also A Synopsis; link below.)
Mass-energy is thus intrinsic to the individual radiaton and nontransferable between radiatons.
Only momentum – and momentum alone – is transferred between radiatons in any and all interactions in nature. 

The radiaton is thus the classic perfectly elastic particle, with absolute mass, say, m, and absolute energy, say, e.
The mass of any body of matter – from quarks to quasars – thus becomes simply its (dimensionless) radiaton number.
Likewise, the energy of a quantum such as the photon or neutrino is, again, simply its radiaton number.
