INTRODUCTION
__{__________}

Old massives galaxies, giant strings of galaxies, or iron-rich quasars
can be observed at enormous distances.
Those findings contradict the big bang theory, according to which
the universe should appear very young at such distances.

Here are a few pertinent references:

- Is the Universe older than expected? (1)
10 July 2002

"An analysis of 13.5 thousand million-year-old X-rays (from
quasar APM 8279+5255) , captured by ESA's XMM-Newton satellite,
has shown that either the Universe may be older than astronomers
had thought or that mysterious, undiscovered "iron factories"
litter the early Universe."

And also,

A Universe Older Than Itself?, by Tom Van Flandern (2)

"The large iron content of the quasar is therefore a major puzzle.
Only two explanations appear possible, and either one is going to
upset some theorists:

(1) the Big Bang redshift-distance-age relationship is wrong; or
(2) the early universe contained "iron factories" producing
extra iron by an unknown physical means."

Notice that a third explanation is plausible:
The universe is stable, and the Big Bang never happenend.

- Very Large Telescope unravels new population of very old
massive galaxies (3)

"Those galaxies must have formed when the Universe was only about
2,000 million years old, that is some 12,000 million years ago."
"... these galaxies have structures and shapes more or less identical
to those of the present-day massive elliptical galaxies"
"Says Andrea Cimatti (INAF, Firenze, Italy), leader of the team:
"Our new study now raises fundamental questions about our understanding
and knowledge of the processes that regulated the genesis and
the evolutionary history of the Universe and its structures."


- GIANT GALAXY STRING DEFIES MODELS OF HOW UNIVERSE EVOLVED (4)

"Wide-field telescope observations of the remote and therefore
early Universe, looking back to a time when it was a fifth of
its present age (redshift = 2.38), have revealed an enormous
string of galaxies about 300 million light-years long. This new
structure defies current models of how the Universe evolved,
which can't explain how a string this big could have formed so early."
"The team compared their observations to supercomputer simulations
of the early Universe, which could not reproduce strings this large.
"The simulations tell us that you cannot take the matter in the early
Universe and line it up in strings this large," said Francis.
"There simply hasn't been enough time since the Big Bang for it
to form structures this colossal".

POSTULATES:
__{________}

1) The universe is infinite, Euclidean, stable (non-expanding),
homogeneous and isotropic.
2) The range of the gravitational force is finite.
3) The Cosmological Principle, according to which the universe,
when viewed on sufficiently large distance scales, has no preferred
directions or preferred places, applies.

CONSEQUENCES OF THE POSTULATES:
__{____________________________}

At each point of their trajectory, light and material objects are
subject to a negative acceleration cK.

Indeed, each point of the trajectory can be considered as the center
of a sphere of radius R and mean density \rho, which corresponds to
the mean density of the universe itself. This is valid according to
the second and third postulates.

At the surface of the sphere, the acceleration of gravity is given
by the formula a = GM/R^2, where G is the gravitational constant.
As \rho = M/V and V = (4/3)*\pi*R^3, M/R^3 = (4/3)*\pi*\rho, hence
a = (4/3)*G*\pi*\rho * R

As the dimension of a is L/T^2, the dimension of (4/3)*G*\pi*\rho
is 1/T^2, and the square root of this expression corresponds to
the inverse of a time.

The formula a = (4/3)*G*\pi*\rho * R can thus be written
a = K^2 * d, where K = \sqrt((4/3)*G*\pi*\rho).

To the maximum possible value of R corresponds
a = c^2/R = K^2 * R, hence R(max) = c/K.

Replacing R by c/K in the formula a = K^2 * R, one gets
a = cK, which is the acceleration of gravity at the surface
of a sphere of radius c/K.

As, according to the above postulates, the trajectory of a photon
corresponds to an infinity of such centers, the moving photon will
be subject to a constant negative acceleration cK during its whole
trip, which will lead to its reddening.


THE REDSHIFT IN A STABLE UNIVERSE
__{_______________________________}

A light ray of wavelength \lambda is sent from a point P.
At a distance d from P, the energy loss of a photon of
frequency \Nu is

(hNu/c^2) * cK * d =[/itex] hNu * (K/c) * d,
where h is the Plank constant.

The residual energy hNu(o) of the photon at the distance d is

hNu(o) = hNu - hNu * (K/c) * d = hNu (1 - K*d/c), hence
\Nu(o) = \Nu (1 - (K*d/c), and
\lambda(o) = (1 - (K*d/c) / \lambda

Thus, in a stable homogeneous universe,

z = (\lambda(o) - \lambda) / \lambda= (K/c)d * (1+z), and

[itex]d = (c/K) * z/(1+z)z = d / ((c/K)-d),

where d is the distance between the observer and
the emitter at the instant when the light was emitted.

Interestingly enough, the formula d = (c/K) * z/(1+z), which gives
the light travel time, leads, assuming c/K = 15 Gly, to results which
are very close to those obtained by Ned Wright's calculator when
hypothetizing a flat universe, c/H0 = 13.7 Gly and \Omega M = .27

z d Calculator (5,6)

.1 1.36 1.29
.5 5.00 5.02
1. 7.50 7.73
3. 11.25 11.48
6. 12.86 12.72

The correlation coefficient between those two series of results
is .999.

CONCLUSION
__{________}

Recent cosmological observations are so much at variance with the
predictions of the big bang theory, that an alternative should be
considered. The most obvious one is a stable, non-expanding universe.
The existence of a cosmological negative acceleration explains
the reddening of light relatively to the distance of its source,
according to the relation d = (c/K) * z/(1+z).
Such relation leads to distances which are very close to those
calculated with the help of general relativity.
On the other hand, a negative acceleration cK would explain the Pioneer
anomaly (7,8), that the ESA intends "to put to the test". (9)

This isn\'t attractive at all.\n\nSome advice for future efforts: Some people, like me, with much free\ntime ;-) might be willing to look at an alternative model.

Several\nhundred thousands of man-years of research have produced answers to\nmyriads of questions. It might be, that the standard cosmological model\nis being stretched to its limits now. I also see some of its foundations\ncrumbling, but I expect the standard FRW-model to still stand a long\nlong time. The reason is simple: You cannot expect anybody who has\ninvested half of his professional career into the study of this model,\nto turn from it, unless the evidence for some other model is\noverwhelmingly strong and the inadequeties of the old model cannot be\nignored, not even by the blind. Even then, most senior researches will\nnot turn from their old hobby. But you may be able to convince some\nyoung, less experienced folk, that are more inclined to take some risk\n;-). However, in order to convince somebody to "convert" to your model,\nyou must give them something valuable in return: Your new model must\nhave the potential, at least in principle, to calculate all relevant\nquantities that can be observed in the real universe in an unambigous\nway.

The findings shed some doubts on the standard cosmological model,

A very conventional explanation for the iron problem is, that we might
have the value of the Hubble-Constant wrong by 10-15%. Unfortunately the
often quoted WMAP-value H = 71 km s^-1 MPc^-1 with is small margin of
error (statistical!) gives a false impression of accuracy. Any
systematic error in H will effect the age of the universe, as t \propto
1/H in any cosmology. The systematic errors in H are still large, so the
WMAP-age of 13.7 Gy (with its far too small margin of error!) cannot be
taken as the holy grail of cosmology. Absolute methods (SZ-effect,
lensing, etc) give lower values for H, in the range 60-65 (some lower).
Fits to the recent supernova data give values in the same range low
(60-63). If one assumes H = 62.5 in obvious units, the "WMAP-age" (13.7
Gy) goes up to 15.6 Gy.

Why would this be plausible? What with nucleosynthesis? What with the
CMBR-temperature?

This surely is a problem. However, structure formation is messy. Maybe
some new fit parameters, bias-values etc. will save the standard model
once again?!

These postulates are neither self-evident, nor do they explain anything
better than the standard "big bang" model. Some things (as
nucleosynthesis, CMBR-temperature, position of the acoustic peaks etc.)
they don't explain at all and it is impossible to see, how these things
could be explained in your model without further postulates. In fact,
your model would need several more postulates to explain the even the
more basic observations. This isn't attractive at all.

Some advice for future efforts: Some people, like me, with much free
time ;-) might be willing to look at an alternative model. But even then
this only makes sense, if an alternative model is derived from some
deeper principle or theory. In such a case one might be willing to
(temporarily) look over the weakness of every new model, whenever it is
first proposed: That it can only explain some very few rather general
features. You have to keep in mind, against what you are up: The
standard cosmological model has been imminently successful. Several
hundred thousands of man-years of research have produced answers to
myriads of questions. It might be, that the standard cosmological model
is being stretched to its limits now. I also see some of its foundations
crumbling, but I expect the standard FRW-model to still stand a long
long time. The reason is simple: You cannot expect anybody who has
invested half of his professional career into the study of this model,
to turn from it, unless the evidence for some other model is
overwhelmingly strong and the inadequeties of the old model cannot be
ignored, not even by the blind. Even then, most senior researches will
not turn from their old hobby. But you may be able to convince some
young, less experienced folk, that are more inclined to take some risk
;-). However, in order to convince somebody to "convert" to your model,
you must give them something valuable in return: Your new model must
have the potential, at least in principle, to calculate all relevant
quantities that can be observed in the real universe in an unambigous
way. I don't see this in any of your Postulates. In fact, these
postulates appear to be clearly in conflict with observations - and even
logic.

Interesting, but in not very conclusive. You can always find a tight
correlation of your model with a hypothezed universe. What one generally
wants to see is a genuine calculation of the luminosity distance versus
redshift in your model and a comparison with the best available data on
standard candles, i.e. the most recent supernova data. Don't bother to
do it though, it won't work.

this is not obvious at all! What with Olber's paradox in a stable,
non-expanding universe? If there is non-zero acceleration (as you
claim), how can your model be non-expanding?

I thought, your postulates should vindicate GR. Why then bother to
compare to GR?

How do you explain, that the Pioneer-acceleration is supposed to be in
the direction of the sun? This is in clear conflict with your postulate
of an isotropic, homogeneous universe!

May I suggest, that you take a good book about GR and start some serious
study of this truly remarkable and by no way easy subject. To me this
seems the best way to find out, "was die Welt im Innersten
zusammenhält". Maybe when you have understood the more intricate details
of GR (which is very hard work, I can assure you that, at least if you
are interested in true, deep understanding), you might find some new and
interesting model, which surplants the big bang?!
