Default CRIMESTOP IN COSMOLOGY

http://www.liferesearchuniversal.com...html#seventeen
George Orwell: "Crimestop means the faculty of stopping short, as
though by instinct, at the threshold of any dangerous thought. It
includes the power of not grasping analogies, of failing to perceive
logical errors, of misunderstanding the simplest arguments if they are
inimical to Ingsoc, and of being bored or repelled by any train of
thought which is capable of leading in a heretical direction.
Crimestop, in short, means protective stupidity."

Cosmologists stop short, as though by instinct, at the threshold of
the dangerous thought: "The properties of the tiniest particles should
dictate what the COSMOLOGICAL REDSHIFT looks like":

http://arstechnica.com/science/news/...dard-model.ars
"If cosmology has become a part of elementary particle physics, as
Nobel Laureate George Smoot put it at the Lindau Meeting, it's because
we've found that "it's a continuum from quantum mechanics to clumps of
matter to galaxies." The properties of the tiniest particles should
dictate what the Universe looks like, but all the cosmological data is
telling us there must be something in addition to what we know about,
dark matter particles that we haven't yet identified."

For the moment there are only two official hints in Internet going
beyond the threshold, one of them recently suppressed:

http://www.cs.unc.edu/~plaisted/ce/redshift.html
David A. Plaisted: "This suggests that the red shift may be caused by
something other than the expansion of the universe, at least in part.
This could be a loss of energy of light rays as they travel, or A
DECREASE IN THE SPEED OF LIGHT..."

http://www.sciscoop.com/2008/10
"Does the apparently constant speed of light change over the vast
stretches of the universe? Would our understanding of black holes,
ancient supernovae, dark matter, dark energy, the origins of the
universe and its ultimate fate be different if the speed of light were
not constant?.....Couldn't it be that the supposed vacuum of space is
acting as an interstellar medium to lower the speed of light like some
cosmic swimming pool? If so, wouldn't a stick plunged into the pool
appear bent as the light is refracted and won't that affect all our
observations about the universe. I asked theoretical physicist Leonard
Susskind, author of The Black Hole War, recently reviewed in Science
Books to explain this apparent anomaly....."You are entirely right,"
he told me, "there are all sorts of effects on the propagation of
light that astronomers and astrophysicists must account for. The point
of course is that they (not me) do take these effects into account and
correct for them." "In a way this work is very heroic but unheralded,"
adds Susskind, "An immense amount of extremely brilliant analysis has
gone into the detailed corrections that are needed to eliminate these
'spurious' effects so that people like me can just say 'light travels
with the speed of light.' So, there you have it. My concern about
cosmic swimming pools and bent sticks does indeed apply, but
physicists have taken the deviations into account so that other
physicists, such as Susskind, who once proved Stephen Hawking wrong,
can battle their way to a better understanding of the universe."
