Nobody has refuted the argument that Martin Whewell has put forward
It is known that the redshift in the star spectrum can also be
interpreted by supposing that photons lose energy travelling through the
vacuum from a galaxy to the earth and hence decreasing their frequency -
Acoording to Einstein's relation between energy and frequency.
The "Doppler effect" interpretation implies the expansion os the
Universe.
The "photon energy loss" interpretation may imply that the vacuum is not
an absolute vacuum but is just the absence of ponderable matter

Definitely.  That is the practical aspect of the affair.  But I meant 
a more basic aspect, namely that you can't set up a general experiment 
based on "look if something, anything, happens".  At least not on 
finite budget and within finite time.  You need to have at least a 
rough feeling what is it you're looking for.

You cannot.  At most you can prove that you did take into account all 
you could think of.  Which will amount to a finite list, leaving still 
a potentially infinite list of things you couldn't think of.

You forget, Brian --- Keith doesn't =BELIEVE= in the existence of a
vacuum !!!  If there's even =ONE= oxygen-molecule per cubic meter, 
Keith believes that said molecule will force the light in the KTX to
travel at 'c' relative to *it*. He has consistently refused to listen 
to discussions of the ``extinction theorem'' and its relevance to this
question.  Likewise, he has consistently ignored the fact that his pet
hypothesis implies the Sagnac experiment should =ALSO= yield a null
result, whereas in fact a POSITIVE result was observed.  Finally, he
has consistently ignored the fact that his pet hypothesis will cause
conservation of charge to fail in inhomogeneously flowing media,
unless =MAJOR= modifications to Maxwell's equations are made --- 
such as those discussed by Thomas E. Phipps in his paper ``On Hertz's
Invariant Form of Maxwell's Equations'' [_Physics Essays_ v.6, no.2,
pp.249--56, (1993)].
Keith has consistently responded to each of these issues with such

Huh? I do not understand this last sentence. Of course the predictions
differ. Now respond to the point of the paragraph. There is no right
when referring to these theories. We don't know Reality. What we have
are theories the explain and predict. CM does a great job. GR does a
better one, and contains CM inside it.

I think we have gotten to an important issue here. It is true that we
cannot, as a practical question, distinguish between them. But if we
can't tell them apart, then there is no reason to pick one over the
other. And understand, the GR equations at low velocities look very
much like the CM equations. There are extra terms in GR, but they are
zero, or so close to zero that we can never tell the difference.

But we don't take Einstein as a given. We don't have givens. We have
theories, developed from data, to explain and predict. If I knew (in
the revealed knowledge, from the mouth of God, kind of knew) that GR
was the correct theory of reality then I could say CM was wrong. We
don't have that kind of knowledge.

I have no idea what principles the universe contains/is run by. I know
the models we have to explain our observations. I don't even know if
the models say anything about any principles. I think this is an
important point.

It is possible. It is more likely that we have different concepts of
what science is and what it says. It is frequently true that I lack
the background to understand both you and Silke. I have chosen to stay
out of the discussions where I know that is true and to tread very
carefully where I suspect it.
Moggin, I suspect you thought my last line was an insult. It was not.
It is an observation. The relationship between CM and GR is
mathematical. You need the math to follow the steps in reasoning.
There have been many a night were I was sure I understood the words,
but could not follow the math. And had to work and work until I could
see what was going on. Only then did the words in the next step make
sense.

First off... i can tell that you, being an intelligent individual, may
see the logic in this:
at one point i belived that 'God' was TIME... since nothing tangible or
comprehendable may exist without it,(agree? if time stopped... what
would fill the gap between it's end and start?) it seemed logical... And
way leading to way, i figured that time was in fact, only a part of
infinity... and allthough the universe is finite... it is ever expanding
(by the views of science). so therefore...  the bible claims that God is
love, and man is created in his image (both of which can be excluded),
and that man is a part of God... are not Time and the Universe a part of
God? 
Well...to shorten (i would have to write a book) i now have made my own
theory that- God is everything. It may sound as a cheap and easy
explaination, but it does make sense in all situations...(ex: all
objects exist in position realative to all other objects) 
Sorry that i had not the time to explain myself well, and  i am aware
that i may have subsumed myself a fool in your eyes, but i can say no
more at the time, sooo... forgive me if you will, And read my book when
i finally do write it... Thanx...

Jim, I expected much better from you!  Neutrinos have NEVER been
detected directly.  You know that.  They are deduced from SR's equations.
Don't gloss here so the youngins  don't get confused.
Don't you get it Jim?  It's too simple.  An extra frame in SR's derivation
throws extra energy into the whole system.  The neutrino is there to
take up the slack.
If you read the AD pages Jim, you and others would see the answer to
many of your questions.  You don't want to look at the Buechner/Van de
Graaff experiment in MIT in 1946.  It proves that the electron-neutrino
doesn't exist.  It's repeatable today.  How many times do I have to
say it.  Read it Jim and refute it here.  I am waiting.  My guess is that
you can't understand it because you refuse to look at it.
What are neutrino detectors dectecting if not neutrinos?  FAQ on our
pages:  why do they go around burying them under mountains, water,
and put them near penguins?  To avoid false hits.  Jim, neutrino
scientists
get false hits.
Neutrino beams are indirectly assumed to be there so energy conservation
works out for SR.
I know YOU won't see it Jim, but others do.  I guess it's too simple.
No tensors here.  I got a degree in advance calculus.  Don't need it here
Jim.  Just algebra.
What excuses will you come up with next?  You won't look at Beuchner
Van de Graaff.  You also refuse to see this very simple statement:
     SR values - EXPERIMENTAL values = NEUTRINO SPECTRUM
     AD values - EXPERIMENTAL values = ZERO  
Before we part ways, tell me and the world that you understand the
above description - NOT agree with it - but understand it.  It is very
very simple.  YES or NO.  No ring-around-the-rosies.  No feel good getting
together with your buds and bashin' AD.  Just YES or NO.
CAN YOU DO IT???  Here it is again:
     SR values - EXPERIMENTAL values = NEUTRINO SPECTRUM
     AD values - EXPERIMENTAL values = ZERO  
Do you understand the description?  YES or NO.

Irrelevant.  Whatever he takes "the Einsteinian constant" to be -- and
the number of reasonable options is strictly delimited by the content
of GR -- his assertion that "it is the very concept of variability" is
physically absurd.  As a bonus, you may note that Derrida's pervasive
and habitual conflation of suppositio formalis and suppositio simplex
(elsewhere also conflated with suppositio materialis) rules out even
an elementary degree of understanding of Platonist linguistics.

OK, now that the debate becomes more sensible, on one hand, while 
weering off toward irrelevancies on the other, I may join in for a 
short while.  I'll try to keep the math to minimum, don't think I can 
quite avoid it, though.  I'll also try to divide the subject matter to 
few separate parts.
Approximations:
Approximations are used and will continue to be used, constantly.  
There are very few things that can be calculated exactly (not to even 
mention measured).  When you calculate the perimeter of a circle, you 
use pi.  But, in reality you use just an approximation to pi, since 
the number pi itself cannot be represented by any finite number of 
digits.  When you solve a quadratic equation, you've in principle an 
exact formula to do it.  However, the formula involves a square root 
which in most cases, again, cannot be represented by a finite number 
of digits.  So, again, your calculated result is an approximation.  
When your calculator gives you the sine or cosine of an angle, it is 
using an approximation to derive it.  The full formula involves an 
infinite series which would take an infinity of time to sum.  So you 
use a truncated version of the series, just a finite number of terms, 
and throw away the rest.  That's an approximation.
Now, it is in the nature of approximations that they are exactly right 
at a single point, or at most at a limited number of points.  So, if 
we consider anything that is not "exactly right" as being "wrong" then 
an approximation is almost always wrong.  However, that's not the way 
these things are wieved, whether in scientific or in common usage.  
The normal approach is toconsider the approximation "right" if the 
error involved is of no consequence for the issue at hand.  Mind you, 
this involves two things.  First, we've to be able to estimate the 
error (an approximation without an error estimate is worthless).  
Second, there is the matter of "the issue at hand".  different 
situations and applications involve different error tolerance.  in 
some casee an error of 1% is acceptable, in other cases anything 
bigger then 0.00001% is too much.  But there is no conceivable case 
when anything but the exact result is already "wrong"
Approximations in physics:
Once you get from mathematics into physics, there are additional 
errors involved.  Physics relies on measurements which can never be 
performed with infinite accuracy.  Instead of philosophising, lets 
look at the "standard problem" of mechanics which can be formulated as 
follows:
Given all the forces acting on a body as well as its position and 
velocity at some time, calculate its position and velocity at any 
future time.
A theory of mechanics is measured by its ability to achieve the above, 
i.e. to calculate values which will match the measured values at this 
future time.  But:
1)  It is not possible to take into account all the forces acting on a 
given body.  To do this you would've to include, for example, the 
gravitational forces exerted on this body by any other object in the 
universe.  This in term will involve knowing the position and velocity 
of any other body in the univrse (most of which you can't observe and 
you don't know they exist).  Not to mention the random impacts of air 
molecules (assuming the measurement is performed on Earth) on your 
test body.  To take this into account you would have to know the 
future trajectories of all the molecules in the atmosphere.  So you 
would've to solve their equations of motions too.  To make a long 
story short, in order to know the exact force acting on your test
body you would need to know the state of motion of everything in the 
universe.  So, you pick the forces that you know to be relevent, at 
the level of accuracy you care about, and ignore the rest.
2)  The initial position and velocity also cannot be measured with 
infinite accuracy.  During the time you measure them, molecules attach 
themselves to the body or evaporate from its surface.  Electromagnetic 
waves, present everywhere, impact on it and influence the very 
parameters you try to measure.  All these effects are incredibly small 
but, they are non zero and if we consider any result with nonzero 
error to be wrong, then your initial data is wrong.
So, even if by some magic we can be assured that the dynamical theory 
we use is "exact", we still use it with an approximate force and 
approximate initial conditions.  Then, when we want to compare the 
predictions with the results, we've to, again, to measure position and 
velocity and same measurement errors as in (2) are involved again.  
Like it or not, we compare an approiximate calculation with an 
approximate measurement.  And, if within the accuracy of these 
approximations the predictions and the measurements match, we call it 
"right".  That's the only sensible approach.
But, I mentioned abovean "exact" theory.  How can we know that we've 
an exact theory.  The answer is, we cannot.  Since the only way to 
verify the "exactness" of a theory is to compare its predictions with 
measurements, all the approximations above are involved in the 
process.  So the most we can say about a theory is that within 
experimental accuracy it agrees with the data.  That's it and you'll 
never have more.
OK, now that we got this stuff out of the way, we can talk about 
classical mechanics versus relativity.  Now, I don't subscribe to the 
notion mentioned by some that maybe within the realm of small 
velocities relativity is "switched off" and classical mechanics 
becomes an "exact theory".  I agree with you that the idea that there 
are two different sets of rules shouldn't be taken seriously.  There 
is no reason to doubt that relativity superceeds classical mechanics 
globally.
However, it is also true that over a broad range of physical 
parameters the results given by classical mechanics and relativity are 
extremely close.  In fact over most of the range that is of practical 
interest to us, the results are experimentally indistinguishable.  
This already suffices to classify classical mechanics as an excellent 
approximation to relativity over a broad range.  And an approximation 
isn't "wrong", it just is "inexact".
This however still doesn't mean that much.  If relativity would 
consist of abandoning all or most of the notions of classical 
mechanics and buikding from scratch then you could claim that in 
principle classical mechanics is wrong and it just happens to yield 
good results over some region due to a lucky coincidence.  This is not 
the case however.  Relativity carries over almost all the notions of 
classical mechanics, intact.  It changes exactly one aspect, the issue 
of transformations between reference frames and even this one is 
changed in such way that classical mechanics resides within relativity 
as a special or limiting (sorry, couldn't avoid it) case.  Thus by all 
rights relativity can be considered a generalization of classical 
mechanics.
So, where does it leave us.  Is classical mechanics "right".  No, not 
quite.  Is it "wrong".  Again, no.  It is a limited scope theory, 
which is useful in its own right within some (significant) range of 
physical parameters and serves as an excellent foundation for theories 
of more general scope.  Quite a far cry from being simply "wrong" in 
my opinion.
Now, you may argue that all this doesn't matter and as far as you're 
concerned anything that's not exactly "right" is "wrong".  If such is 
the case then you demand from science a religious certitude, andyou 
can argue the issue with Gordon, not with me.

probability wave definitely is NOT just a matter of not knowing yet. 
A wave of not knowing interferes with itself. Yes, it's very
counter-intuitive, non-sensical even. That's why 70 years after the

Subject: Pulsars, little green men; Advanced Alien Communication
From: Archimedes.Plutonium@dartmouth.edu (Archimedes Plutonium)
Date: 31 Oct 1996 02:27:32 GMT
--- quoting NOTABLE 20TH-CENTURY SCIENTISTS ---
   HEWISH
 It crossed the minds of some of the team members that perhaps the
pulses were being transmitted by alien beings, or "little green men,"
as they termed them. Believing that if the press was notified of the
team's investigation, journalists and reporters would descend en masse
upon the observatory, Hewish kept the work quiet....
   On February 24, 1968, Hewish, along with his colleagues at the
observatory, finally published a paper in the journal NATURE detailing
their findings;...
   .... however, both Thomas Gold .. and Franco Pacini proposed that
pulses are caused by beams of radiation that pour out from spinning
neutron stars, which measure several kilometers across and contain a
mass greater than that of the sun.
--- end quoting NOTABLE 20TH-CENTURY SCIENTISTS ---
  This recent conjecture of mine is perhaps the second most important
science conjecture I have ever entertained. After the 231PU theory,
this idea is of immense importance because should we be far behind in
the level of intelligent life, our whole attitude and outlook on life
changes.
  I could spend some time discussing on how little guidelines are given
for science priorities of our present society. We spend so much money
time and resources on minor things such as the "what caused the
Dinosaur extinction" or the huge amounts spent on high energy particle
physics all for what? to chase an illusive Higgs particle which
promises nothing once found.
  I should spend some time discussing the pragmatics of science
priorities.
   Suppose most pulsars are some EM cobalt nickel stars, some heavy
element stars but suppose just 1% of the pulsars are Aliens
communicating. How much more advanced would they be over us in order to
enable them to build machines that can mimic the pulsing of natural
physical EM stars?
  The question here is , how important of a fact is it that there exist
Advanced Aliens and that we can learn about them? Is this knowledge of
greater importance than how the Dinosaurs died? I say immensely more
important. And is the knowledge of Advanced Aliens far more important
than chasing the Higgs boson, again I say definitely yes.
  The point I am making is that weigh the relevant importance of
something in science with how much time and money should be spent on
it. In this light, supposing there is but a tiny chance that some
pulsar is Alien Advanced communication. Even with that tiny chance, the
huge, the extraordinarily large importance such a fact makes on us,
dictates and demands that we apply diligent, painstaking time and money
and research into the question of whether anyone of these pulsars is in
fact Advanced Aliens.
  Due to its huge importance, estimates of what form of communication,
what frequencies, what the actual messages may be saying, what type of
physics machinery would make these pulses should be explored fully. We
should go into these projects with the attitude that Advanced Aliens
exist, until we can find evidence that we are  the most advanced
creatures.
  Now reading the above selection on Hewish, made me to think that such
could be a true accounting of history. But there is one fact that
stands out in the history of biology and physics and that fact is that
one science is never far behind, if ever, from the other.  Call it Bio
complements Physics, or Bio lock step in progress with Physics. Notice
that the battery was made from electric eel and frogs legs research.
Thereby, pulsars, for the most part are natural physical processes such
as EM on cobalt-nickel star cores or heavy lead-uranium star cores etc.
However, the most advanced life would have studied these pulsar stars
and imitated them to the point of building a machine that would imitate
them. Then they used these machines to communicate to other aliens. It
is impossible for life as we know it to travel at the speed of light.
So rather than to visit in person your neighbors at 10,000 light years
away, it is easier to pulse them.
   Reading the Hewish selection makes me think that if governments
wanted to study pulsers for alien life messages, governments would want
to arrest the pulsar data from the general public and study it in
secrecy. So a ruse would be used to placate the general public and to
say they are "neutron stars". This way, secret govt agencies control
the data of "pulsars advanced aliens" leaving the scientists with the
wild goose chase of a neutron baloney with their general public cow
towed by the scientists. And should any scientists become wise to the
fact that some of these pulsars are better seen as alien communication
then the government agency simply discredits the scientist as a 'gone
loco weed'. In this sense, it would not do the general public much good
if they knew that some pulsars are Advanced Aliens, they would cause
panic and hysteria.
  I am not saying that it is a bad thing that the govt takes over the
"research into pulsar = Advanced Aliens". The government would offer a
controlled and orderly news release of the facts. The problem would be
for the govt to ever release any of the facts for they may have the
propensity to never release the facts until it is far far too late.
Another good aspect of the govt controlling the studies of pulsars is
that they could spend money as they saw fit, being that money was no
obstacle. Here one can envision that should the US govt agency find a
pulse that is repeating in 6 different pulsars and the message is one
element 231@94 being pulsed between these 6 stars. Then the govt can
afford to set up a supercomputer and listen closely to those 6 pulsars.
  If the 231PU theory is correct, then advanced life would have
discovered this theory a long time ago and would be using that theory
name as the opening lines of introduction to other advanced aliens.
  If we get a pulsing machine up, what wisdom would we use as a letter
of introduction? Of course, our most comprehensive theory of all---
Atom Totality and we would pulse 231*94 throughout the sky for other
advanced aliens to respond in like kind. Once we establish letter of
introduction with another,then we would pulse new and more information
with that particular contact.

Subject: NEW BOOK: Where is Everybody?
From: Graham Beech
Date: Thu, 31 Oct 1996 10:54:26 GMT
NEW BOOK: 
WHERE IS EVERYBODY? THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE
Excuse this "commercial", but our latest book is so relevant to this 
news group that I thought that many people would like to know about 
it. Here goes:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
NEWS RELEASE . . . NEWS RELEASE . . . NEWS RELEASE
Are we really alone in the Universe? The recent exciting discoveries 
by NASA scientists of the first evidence of life on Mars begins to 
bridge the gap between science fiction and science fact, giving new 
urgency to our questions. How different from ourselves would 
intelligent life be on other worlds? Might we be able to receive 
broadcasts from alien civilisations? All the issues raised are 
addressed by the timely publication of "Where is Everybody?: the 
Search for Extraterrestrial Intelligence" (ISBN: 1 85058 576 8) by 
Edward Ashpole. The book is published on 28th October by Sigma Press 
and the price is not at all astronomical - just  6.95.
"Where is Everybody?" examines our reasons for thinking that life is 
a universal phenomenon. Edward Ashpole, who lives in Pembrokeshire, 
UK, has been a science correspondent for 30 years and is a member of 
the Association of British Science Writers. He believes that his book 
opens up our thinking about the ways that astronomers are searching 
for possible evidence of ET. He says, "If we examine the science that 
is currently available to us, we have to conclude that possible 
evidence of ET could equally well be within the Solar System as out 
there amongst the stars."
This is a book for the general reader - no prior knowledge is 
required and absolutely no mathematics. Edward presents his readers 
with a wide range of scientific evidence and introduces some new 
ideas based on this. All of the recent developments and advances have 
been examined and are presented in a clear, readable form. There are 
clear diagrams - many of the illustrations have been downloaded 
directly from Internet web sites provided by NASA.
The prospect that we may not be unique may be exciting or disturbing, 
but with further discoveries seeming inevitable, this is the book 
that no one with an interest in life and intelligence in the universe 
can afford to miss.

Consider 30 = 2*3*5, I know 1/4 is a 2 digit 'tridecimal' fraction (0.7F) 
rather than a 1 digit '6decimal' fraction (0.F). But it has a much
smaller multiplication table (only 900 entries).
If I recall correctly the babylonean system was actually represented as
pairs of base 6 and base 10 digits so perhaps one could get away with 196 =
6*6 + 10*6 + 10*10 entries (I will have to think about that number).

  This is a big problem of people who go into math for a career, just
simply cannot see the forest for the trees, and their Net appearances
vouch this blind spot. You sound like early school burnout Nahay. Join

Notice the graphs of the above four trig functions.
 We can see discreteness,  quantization in the tangent graph
  Each branch of the tan graph is a discrete separate particle
 We can also sort of see positive curvature in each of those tan
branches.
  Now inspect the hyperbolic tangent graph. Can we see Lobachevskian
geometry in that graph?
  If i is a 90 degree turn of Reals, what is arctan compared to tan,
and what is tanh compared to tan? And what is tanh compared to arctanh?
All important questions for we want to penetrate into the heart of what
these 3 distinct geometries are. These geometries are the heart of
atoms for electrons are mostly space and space is geometry.
  The history of what is current geometry and mathematics has been one
of less than proud achievement. One only needs to look at what present
day math people consider Riemannian, Lobachevskian and Euclidean
geometry. In summary of 1993 mathematics for geometry it is this--- no
math person before me ever thought that Riemannian and Lobachevskian
geometry had their own unique coordinate system. All math people before
me thought that the Reals and the Complex could be used for modelling
Riem and Loba geometries. Noone before me realized that Riemannian
geometry intrinsic coordinate system was the All-adics. Noone before me
realized that the Doubly Infinites were the intrinsic numbers that make
the Lobachevskian geometry.
  But this is an important point in math also, that great important
discoveries in math take millenium to get there proper due. Whereas an
equally important discovery in physics or biology will reap their just
rewards in a decade. That is why I now just post my math, let the
milleniums prove me correct and spend the majority of my time over in
the ** important ** subjects of physics and biology and the sciences
where great discoveries are treated in a timely manner.
  The future of mathematics is dark and bleak. What will happen to her?
She will find out that P-adics are essential in some field of physics
where the Finite Integers simply fail. When news of this reverberates
around the world, it will be shortly thereafter that much of the sand
castle proofs that mathematics has relied on will all cave in. You see,
Naturals = Infinite Integers will clean house of mathematics. And when
it is swept clean, math will no longer be a separate subject.  HOORAY,
for math will then be were it true belongs --- a mere sub-subject of
physics and math will foreever thence lie as a subdepartment of
physics. Mathematics, on the day that physics shows where the P-adics
are necessary ( my guess is the Quantized Hall Effect) and the Finite
Integers inadequate is the day that science liberated itself, pulled
the excalibre out of the anvil and freed itself of mathematics, and
showed itself as King over mathematics. And on that day, mathematics
will scrub and clean itself up, for it will forever hencefoward be in
tune with experiments that all the sciences are in tune with. But
somehow, math has been this naughty , errant boy of more than 2
thousand years. Why, math has even taken on the aura of religion.
