Default GENERAL RELATIVITY WITHOUT SPECIAL RELATIVITY

Now all Einsteinians (except for silliest zombies) know that Einstein
1905 light postulate is false so special relativity is just a
dangerous relict of a bygone era and should be abandoned:

http://www.logosjournal.com/issue_4.3/smolin.htm
Lee Smolin: "Quantum theory was not the only theory that bothered
Einstein. Few people have appreciated how dissatisfied he was with his
own theories of relativity. Special relativity grew out of Einstein's
insight that the laws of electromagnetism cannot depend on relative
motion and that the speed of light therefore must be always the same,
no matter how the source or the observer moves. Among the consequences
of that theory are that energy and mass are equivalent (the now-
legendary relationship E = mc2) and that time and distance are
relative, not absolute. SPECIAL RELATIVITY WAS THE RESULT OF 10 YEARS
OF INTELLECTUAL STRUGGLE, YET EINSTEIN HAD CONVINCED HIMSELF IT WAS
WRONG WITHIN TWO YEARS OF PUBLISHING IT."

Joao Magueijo, PLUS VITE QUE LA LUMIERE, Dunod, 2003, pp. 298-299:
"La racine du mal etait clairement la relativite restreinte. Tous ces
paradoxes resultaient d'effets bien connus comme la contraction des
longueurs, la dilatation du temps, ou E=mc^2, tous des predictions
directes de la relativite restreinte. (...) La consequence en etait
inevitable: pour edifier une theorie coherente de la gravite
quantique, quelle qu'elle soit, nous [Joao Magueijo et Lee Smolin]
devions commencer par abandonner la relativite restreinte. (...) Mais,
comme nous l'avons vu, celle-ci repose sur deux principes
independants. Le premier est la relativite du mouvement, le second la
constance de la vitesse de la lumiere. Une des solutions possibles a
notre probleme pouvait etre d'abandonner la relativite du mouvement.
(...) C'est une possibilite bien sur, mais nous avons choisi
l'alternative evidente: preserver la relativite du mouvement, mais
admettre qu'a de tres hautes energies, la vitesse de la lumiere ne
soit plus constante."

"Loop quantum gravity also makes the heretical prediction that the
speed of light depends on its frequency. That prediction violates
special relativity, Einstein's rule that light in a vacuum travels at
a constant speed for all observers..."

http://www.edge.org/3rd_culture/smol...n03_print.html
Lee Smolin: "Now, here is the really interesting part: Some of the
effects predicted by the theory appear to be in conflict with one of
the principles of Einstein's special theory of relativity, the theory
that says that the speed of light is a universal constant. It's the
same for all photons, and it is independent of the motion of the
sender or observer. How is this possible, if that theory is itself
based on the principles of relativity? The principle of the constancy
of the speed of light is part of special relativity, but we quantized
Einstein's general theory of relativity.....But there is another
possibility. This is that the principle of relativity is preserved,
but Einstein's special theory of relativity requires modification so
as to allow photons to have a speed that depends on energy. The most
shocking thing I have learned in the last year is that this is a real
possibility. A photon can have an energy-dependent speed without
violating the principle of relativity! This was understood a few years
ago by Amelino Camelia. I got involved in this issue through work I
did with Joao Magueijo, a very talented young cosmologist at Imperial
College, London. During the two years I spent working there, Joao kept
coming to me and bugging me with this problem.....These ideas all
seemed crazy to me, and for a long time I didn't get it. I was sure it
was wrong! But Joao kept bugging me and slowly I realized that they
had a point. We have since written several papers together showing how
Einstein's postulates may be modified to give a new version of special
relativity in which the speed of light can depend on energy."

However Einsteinians (except for silliest zombies) also know that, in
general relativity, Einstein secretly abandoned his 1905 false light
postulate and reintroduced VARIABLE speed of light:

"What Can We Learn about the Ontology of Space and Time from the
Theory of Relativity?", John D. Norton: "In general relativity there
is no comparable sense of the constancy of the speed of light. The
constancy of the speed of light is a consequence of the perfect
homogeneity of spacetime presumed in special relativity. There is a
special velocity at each event; homogeneity forces it to be the same
velocity everywhere. We lose that homogeneity in the transition to
general relativity and with it we lose the constancy of the speed of
light. Such was Einstein's conclusion at the earliest moments of his
preparation for general relativity. ALREADY IN 1907, A MERE TWO YEARS
AFTER THE COMPLETION OF THE SPECIAL THEORY, HE HAD CONCLUDED THAT THE
SPEED OF LIGHT IS VARIABLE IN THE PRESENCE OF A GRAVITATIONAL FIELD."

http://www.math.ucr.edu/home/baez/ph..._of_light.html
"Einstein went on to discover a more general theory of relativity
which explained gravity in terms of curved spacetime, and he talked
about the speed of light changing in this new theory. In the 1920 book
"Relativity: the special and general theory" he wrote: ". . .
according to the general theory of relativity, the law of the
constancy of the velocity of light in vacuo, which constitutes one of
the two fundamental assumptions in the special theory of relativity
[. . .] cannot claim any unlimited validity. A curvature of rays of
light can only take place when the velocity of propagation of light
varies with position." Since Einstein talks of velocity (a vector
quantity: speed with direction) rather than speed alone, it is not
clear that he meant the speed will change, but the reference to
special relativity suggests that he did mean so."

"So, it is absolutely true that the speed of light is not constant in
a gravitational field [which, by the equivalence principle, applies as
well to accelerating (non-inertial) frames of reference]. If this were
not so, there would be no bending of light by the gravitational field
of stars....Indeed, this is exactly how Einstein did the calculation
in: 'On the Influence of Gravitation on the Propagation of Light,'
Annalen der Physik, 35, 1911. which predated the full formal
development of general relativity by about four years. This paper is
widely available in English. You can find a copy beginning on page 99
of the Dover book 'The Principle of Relativity.' You will find in
section 3 of that paper, Einstein's derivation of the (variable) speed
of light in a gravitational potential, eqn (3). The result is,
c' = c0 ( 1 + V / c^2 )
where V is the gravitational potential relative to the point where the
speed of light c0 is measured."

So Einsteinians will continue to refer to and worship general
relativity but, on the other hand, they will force Einstein zombie
world to forget the dangerous special relativity (and Einstein zombie
world will forget it very soon):

http://www.newscientist.com/article/...-big-bang.html
NEW SCIENTIST: "The theory that the recycled universe was based on,
called loop quantum cosmology (LQC), had managed to illuminate the
very birth of the universe - something even Einstein's general theory
of relativity fails to do....LQC is in fact the first tangible
application of another theory called loop quantum gravity, which
cunningly combines Einstein's theory of gravity with quantum
mechanics....When the team used LQC to look at the behaviour of our
universe long after expansion began, they were in for a shock - it
started to collapse, challenging everything we know about the cosmos.
"This was a complete departure from general relativity," says Singh,
who is now at the Perimeter Institute for Theoretical Physics in
Waterloo, Canada. "It was blatantly wrong." Ashtekar took it hard. "I
was pretty depressed," he says. "It didn't bode well for LQC."
However, after more feverish mathematics, Ashtekar, Singh and
Pawlowski solved the problem. Early versions of the theory described
the evolution of the universe in terms of quanta of area, but a closer
look revealed a subtle error. Ashtekar, Singh and Pawlowski corrected
this and found that the calculations now involved tiny volumes of
space. It made a crucial difference. Now the universe according to LQC
agreed brilliantly with general relativity...."
