This doesn't sound like void space to me. Also its talking about
photons interacting with the space-time atoms doesn't sound like
void
space.

When Uncle Albert kicked out the "aether", he had to substitute
something for it. The mathematical abstraction "space-time" became
its
surrogate. That way, space could still be an abstract 'something'
while abiding by the mandate that there is "no medium". So when
somebody talks about "space-time atoms", this same edict is adhered
to. It forbits existance of a literal spatial medium, either the
archaic "aether" or the SPED.

Einstein's only objection to the classical aether was that it couldn't
be used as a rest frame against which to mesure absolute motion. (The
quote is out there if only I had time to find it.) . . .

Here's the only "sourced" quote i could find...

"We may assume the existence of an aether; only we
must give up ascribing a definite state of motion to it,
i.e. we must by abstraction take from it the last
mechanical characteristic which Lorentz had still left it."

Source: On the irrelevance of the luminiferous aether
hypothesis to physical measurements, in an address at
the University of Leiden (May 5, 1920)

Yes, that's the quote, and the final lines at the end:

"But this ether may not be thought of as endowed with the quality
characteristic of ponderable inedia, as consisting of parts which may
be tracked through time. The idea of motion may not be applied to it."

The detection of the Earth's rotation by interferometer is called the
Sagnac effect:

"The first ring interferometry experiment aimed at observing the
correlation of angular velocity and phase-shift was performed by the
Frenchman Georges Sagnac in 1913, which is why the effect is named for
him. Its purpose was to detect "the effect of the relative motion of
the ether". An experiment conducted in 1911 by Francis Harress, aimed
at making measurements of Fresnel drag of light propagating through
moving glass, was later recognized as actually constituting a Sagnac
experiment. Harress had ascribed the "unexpected bias" to something
else.

In 1926 a very ambitious ring interferometry experiment was set up by
Albert Michelson and Henry Gale. The aim was to find out whether the
rotation of the Earth has an effect on the propagation of light in the
vicinity of the Earth. The Michelson-Gale experiment was a very large
ring interferometer, (a perimeter of 1.9 kilometer), large enough to
detect the angular velocity of the Earth. The outcome of the
experiment was that the angular velocity of the Earth as measured by
astronomy was confirmed to within measuring accuracy. The ring
interferometer of the Michelson-Gale experiment was not calibrated by
comparison with an outside reference (which was not possible, because
the setup was fixed to the Earth). From its design it could be deduced
where the central interference fringe ought to be if there would be
zero shift. The measured shift was 230 parts in 1000, with an accuracy
of 5 parts in 1000. The predicted shift was 237 parts in 1000."

I don't understand. As a practical thing, the Sagnac effect
appears to be very useful. But the article didn't seem to
say whether or not Sagnac's effort to detect "the effect of
the relative motion of the ether" was considered a success
by his peers. Apparently, judging by an ensuing droppage
of any "ether", Sagnac's theoretical goal was not believed
to have been reached?

There is also no description of Michelson's conclusions he
drew from his and Gale's experiment. Did he and Gale
think that the ring interferometer was as ineffective as the
interferometer he used in his experiment with Morley?
(I.e., ineffective as to showing the existence of an ether?)

happy days and...
starry starry nights!
