Conventional Cosmology Critique

COMMENTS:
On model tinkering in the Ptolemaic tradition
Every now and then it is enlightening to
check on the "progress" of conventional cosmology, which, as everyone
knows, embraces the expanding-universe model ---popularly called the Big
Bang model.
The basic Big Bang has a parameter called the scaling factor.
Think of it as the radius of the growing universe. It gets bigger as the
Big Bang universe gets bigger. Technically it is the derivative of this
scaling factor that describes the rate with which the universe is
expanding. It is a measure of the speed of the expansion of the expanding
universe. Simple enough.
However, the model holds that the speed changes over time. For many
years it was believed that the expansion speed was slowing down. But
careful astronomical observations, notably in 1998, revealed that this was
not the case. Expansion wasn't tapering off. It seemed to be ramping up!
Rather than abandon the model, the experts came up with accelerated
expansion. Henceforth they employed an acceleration parameter, which,
technically, is the second derivative of the scaling factor. (If you
are keeping count, that makes three parameters available for theory
manipulation.) As the story goes the universe not only expands but it
expands faster and faster. End of story? No. ...
A few years after that notable crisis of
1998 it was gradually revealed, through even more careful and ever deeper
astronomical observations, that uniform accelerated expansion still
wasn't the answer. (Now at this stage any conscious-and-rational person
would have abandoned the Big-Bang ship especially since there are far
superior models floating around.) Having maintained a tradition of
commitment going back as far as the 1920s when Lemaître formalized the
explosion-idea, abandonment was not an option. And so the experts now came
up with another parameter. Yes, a fourth adjustable factor. Admittedly it
is not very original. If you can't connect with the underlying reality of
the expansion process at least you can connect with the differential
calculus. Ready for this one? The new parameter is the third derivative of
(you guessed it) the scaling factor. They call it the jerk parameter
and means exactly what it says.
Now I assure you I am not making this up
---and in a moment I will do more than assure you by providing the
reference source.
The experts even tell us when, in the
past of the Big Bang, this supposed jerk occurred. (It corresponds to
z = 0.5 or about 5.4 gigayears ago when the universe was 9.2 gigayears old
assuming a Hubble constant, H0 = 20 km/s/Mly.
[1]) Think about this
for a moment; a jerk-event occurred at some particular period of cosmic
time. A special identifiable time! What this means is that the BB universe
now has no less than three special moments in time during its existence:
The beginning time (t=0), the end-of-inflation time, and the
jerk time; all in violation of the cosmological principle
(strong version)! It means a violation of the generally accepted rule that
a real universe must have no special time or place.
It is little wonder that
physicists and cosmologists consider the expanding universe model to be
preposterous! Physicist Sean M. Carroll even named his website "preposterous
universe." And he goes into some detail in his paper, The Cosmological Constant, available at
http://relativity.livingreviews.org/Articles/lrr-2001-1.
Undeterred by considerations of
preposterousness and implausibility, a group of experts, using the latest
high-z supernovae discoveries, presented their ideas for 'improvements' to
the Big Bang. The research paper,
[2] authored by no less than 19
physicists/astronomers, was published in the Astrophysical Journal, June
2004. (See, Riess et al., ApJ 607, 665 (2004)
http://arxiv.org/abs/astro-ph/0402512 )
Their problem can be expressed this way:
For a growing collection of remote supernova events the redshift-distance
curve does not agree with the magnitude-distance curve (magnitude =
apparent brightness). The challenge is to get the theoretical curve
(the redshift-distance graph) to agree with the empirical curve (the
magnitude-distance graph).
And that is why the scaling factor derivatives are so useful. If it is
mathematically necessary to invoke a fourth or even fifth derivative of the
scaling factor, to force-fit the curves, then so be it. The Big Bang,
being, as it is, a mathematical model, literally cannot fail.
What we
are witnessing in conventional cosmology is the "keeping up the
appearances" in the best Ptolemaic tradition.

Baffled by the Preposterous
—Another Admission of Bafflement
Dan Hooper is a practicing physicist. He has applied his
considerable talents to the search for the universe's missing mass and
energy ... and the presentation of the details to a broad audience. He has
written a book about the 95 percent of matter in the universe that is
totally invisible. In his words "This invisible stuff comes in two
varieties —dark matter and dark energy. One holds the universe together,
while the other tears it apart."
In light of the fact that many hundreds of physicists are
involved in this search, and the search has been going on for many years
(well over thirty years), there should be much to report. Unfortunately,
the search has turned out to be a profound disappointment. Dan Hooper finds
himself making the following admission:
| |
"The advances made in
observational cosmology during the past few decades have been
incredible. ... the catalog of distant supernova observations has led
to the discovery that dark energy comprises about 70 percent of our
Universe's density. These findings are remarkable. Sadly, the attempts
to develop a compelling theoretical explanation for these findings
have been not nearly as successful." —Dan
Hooper, Dark Cosmos p173-4 |
|
Dan Hooper is talking about dark energy, the stuff that
is somehow shaping the universe. Here he expands on the "not nearly as
successful" part of his assessment quoted above:
| |
"It's fair to say that the theoretical physics
community is, at least for the time being, entirely baffled when it
comes to dark energy. ..." |
|
An understatement if ever there was one. But then, this is not anything
new. Actually the theoretical physics community has been "entirely
baffled" ever since the adoption of creationism cosmology
—ever since the adoption of a speculation (a far-out hypothesis)
promulgated as science by Georges Lemaître, way back in 1927 & 1929. Take
note, we're not talking about temporary bafflement here. The bafflement
goes way back to the time of Edwin Hubble in the 1920s. (Hubble had the
wisdom to advise caution before jumping to radical unscientific
conclusions.)
The admission is that dark energy, aka
Lambda, aka cosmological constant, aka vacuum energy, is shaping the
universe BUT how it does the shaping —and even what that shape might be— is
a bafflement! ... It is not known what drives this energy nor what shape it
leads to. At least that is the sad situation in Academic Cosmology.
What about the other half of the puzzle —the dark matter?
| |
"As our search has left us with no
known candidate for dark matter, we must turn our attention to the
purely theoretical and ... the branch of mathematics ... "
—Dark Cosmos p80 |
|
Are dark energy and dark matter related?
| |
"Dark energy and matter are, as
far as we [physicists] understand them, completely unrelated
phenomena." --Dark Cosmos p174 |
|
Dark energy (or Lambda) and material matter are
unrelated?!! ... They shape the universe yet are unrelated?!! ... Folks,
the admission of bafflement could not be any clearer. ... Meanwhile, in
DSSU cosmology the two are intimately linked in true Heraclitian tradition
---involving flux, processes, opposites, and harmony.
Academic Astrophysics/Cosmology seems to suffer from a
strange inbreeding of ideas.
Consider the following remarkable claim, made in his 2006
book, by theoretical physicist Hooper:
| |
"The vast majority of cosmologists
are convinced that around 14 billion years ago our Universe was in an
ultra-hot state that expanded over time to eventually become ... the
Big Bang. In fact, I don't believe that I have ever met a cosmologist
who disagreed with this assessment." --Dark Cosmos p206 |
|
I say this is a remarkable claim because these same people
admit the model is preposterous and they admit their puzzlement. I'm
scratching my head. Something is not right here.
Physicists are baffled by the model they have pieced and pasted
together ---their model of the expanding universe. Big Bang for short. Yet
despite the serious and persistent bafflement, they all agree, or so we
keep hearing, on the validity of the Big Bang model!! The academic
colleagues of Dan Hooper, instead of voicing justifiable skepticism
compliantly vote their support!
Now what kind of scientific methodology are these learned
scientists using? Seems rather irrational, doesn't it? The average thinking
person can't help but conclude that there is something seriously wrong
here.
What one is witnessing in academic astrophysics/cosmology
is conformism to official dogma. Science writer Corey S Powell calls it "sci/religion"
(and calls its practitioners the "Priests of sci/religion"). Others call it
"mytho-science." I call it (among other things) the inbreeding of
expanding-universe theories. We are witnessing the 80-year-long inbreeding
of theories based on the biggest unscientific extrapolation in the long
history of science. ...
All the serious models of the universe that have been
debated following the introduction of Lemaître's fireball-universe were
based on whole-universe expansion. They included general-relativity
expansion, steady-state expansion, kinematic expansion, inflationary
expansion, negative-pressure expansion, and quintessence expansion, to name
the most popular ones. Cross fertilize any of them and you still end up
with whole-universe expansion! The expanding universe models have
metaphorically reached an evolutionary dead-end.
And what is blatantly obvious in all this is that Modern
Cosmology (more specifically, Academic Cosmology) has simply NOT
investigated the non-expanding universe. It has never explored the
perfectly natural cellular universe!
Giving the last word to Dan Hooper, who despite his
bafflement, expresses hope,
| |
"Modern physicists hope ... to
find not only a more complete description of nature, but also a more
complete explanation for it." --Dark Cosmos p5 |
