When it comes to destroying human rationality, Einsteinians know no
limits. They continue to do so even when they are trying to abandon
Divine Albert's Divine Theory:

"....time travel, once dismissed as pulp fiction by serious
scientists, has become "something of a cottage industry in the
theoretical physics community", according to Professor Paul Davies,
physicist, astrobiologist and award-winning science writer, who a few
years ago published a book with the engagingly no-nonsense title of
How To Build A Time Machine. In it, Davies makes it clear that
travelling into the future is entirely allowable, according to
Einsteinian laws of physics....Coming back, however, is a different
matter. It is one for which Davies and others have speculated on the
possibility of harnessing the power of "wormholes". Remember those
fearsome tunnels through time and space down which Jodie Foster
hurtled in the film Contact? That was Hollywood's vision, but the
concept of wormholes – originally called "Einstein-Rosen bridges" –
has been speculated on since the 1930s, as tunnel-like shortcuts
through space and time, because the unimaginably powerful
gravitational forces within them could be harnessed to warp the space-
time continuum....It has been speculated that the LHC, once it starts
functioning properly, could possibly form Einstein-Rosen bridges.
"There is a ghost of a chance, but no more than that in my opinion,
that it could create microscopic wormholes," says Davies. Such
thinking involves what he describes as "rather speculative, non-
standard theories of gravitation. If we go with Einstein's General
Theory of Relativity (which attributes gravity to the curving of space
and time), which is what most of the discussion in my book was based
on, then it's not going to happen. But in recent years there has been
increasing attention given to alternatives to Einstein's theory, and
one of those involves additional dimensions of space.".....Much of the
research pertaining to this ever-intriguing topic takes us out of the
relatively solid world of classical physics and Einsteinian theory and
into the realms of quantum mechanics, with scientists questing after
the "holy grail" of 21st-century physics, an overall theory of quantum
gravity, which would supersede Einstein's and be applied to everything
in the cosmos. Among those working towards this are Dr Charles Wang,
reader in physics at the University of Aberdeen. "If we have a
breakthrough in quantum gravity, then time travel would stand a better
chance. We certainly expect some interesting result to come out soon –
although we can't really promise a time machine," he laughs."

A few years ago the salfsame Paul Davies explained why Divine Albert's
Divine Theory should be abandoned:

http://www.prospect-magazine.co.uk/article_details.php?id=5538
Paul Davies: "Was Einstein wrong? Einstein's famous equation E=mc2 is
the only scientific formula known to just about everyone. The "c" here
stands for the speed of light. It is one of the most fundamental of
the basic constants of physics. Or is it? In recent years a few
maverick scientists have claimed that the speed of light might not be
constant at all. Shock, horror! Does this mean the next Great
Revolution in Science is just around the corner?"

Other creators of quantum gravity, the theory "which would supersede
Einstein's and be applied to everything in the cosmos", clearly state
their most important task: ''We need to drop a postulate, perhaps the
constancy of the speed of light'':

http://www.fqxi.org/data/articles/Searching_for_the_Golden_Spike.pdf
"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/smolin03/smolin03_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."

http://roychristopher.com/joao-magueijo-frontier-cosmology
"Likewise, Joao Magueijo has radical ideas, but his ideas intend to
turn that Einsteinian dogma on its head. Marueijo is trying to pick
apart one of Einsteins most impenetrable tenets, the constancy of the
speed of light. This idea of a constant speed (about 3×106 meters/
second) is familiar to anyone who is remotely acquainted with modern
physics. It is known as the universal speed limit. Nothing can, has,
or ever will travel faster than light. Magueijo doesnt buy it. His VSL
(Varying Speed of Light) presupposes a speed of light that can be
energy or time-space dependent. Before you declare that hes out of his
mind, understand that this man received his doctorate from Cambridge,
has been a faculty member at Princeton and Cambridge, and is currently
a professor at Imperial College, London. Hes a MAINSTREAM SCIENTIST
WHOSE MIND IS BEGINNING TO WANDER."

"As propounded by Einstein as an audaciously confident young patent
clerk in 1905, relativity declares that the laws of physics, and in
particular the speed of light -- 186,000 miles per second -- are the
same no matter where you are or how fast you are moving. Generations
of students and philosophers have struggled with the paradoxical
consequences of Einstein's deceptively simple notion, which underlies
all of modern physics and technology, wrestling with clocks that speed
up and slow down, yardsticks that contract and expand and bad jokes
using the word ''relative.''......''Perhaps relativity is too
restrictive for what we need in quantum gravity,'' Dr. Magueijo said.
''We need to drop a postulate, perhaps the constancy of the speed of
light.''
