Write your reply.

assistant: OTOH, the distance between two atoms in a crystal, or body, are not
dependant on the space between them but in the combination of attractive
and repulsive forces remaining in balance (or in a few cases, not in
balance) and the structure of a galaxy depends on the gravity between
the different components more so than the structure of a supercluster
does.
The meter, as a measure, will not increase at all without the speed of
light changing and nor will the length of a meter long steel bar
increase either if the properties of the atoms (and the gravitational
objects which influence it) remain about the same.
Would I be right in assuming that stars are formed in space and tend to
end their lives in the centres of galaxies, due to the gravity drawing
them together more than expansion draws them apart?

How so, when *relative to the space* everything suddenly contracts into
a relatively small central core, from being evenly distributed
throughout the entire volume of space?
Of course, from our perspective, the universe was much smaller when it
started, but that's because we mentally treat the universe as a large
volume of nothingness with stuff in it.
Assuming that the large volume of nothingness was always there, the
production of all the matter into it "looks" like an explosion, but
actually it's virtually the reverse.

Find a club, and go to a sidewalk astronomy night.  On those nights the
club members set up their scopes for free viewing by the passers-by (in
San Diego we call it "Stars in the Park" and do it once a month, outside
the local planetarium).  Spend a bit of time with some scope owners, look
through a few scopes, get a feel for what turns _you_ on... is it
planetary views?, you need a high-power scope, to get big pictures of the
bright planets... do you prefer the glorys of cluster and nubulae? then
you need a fat light-bucket...  maybe you aren't really that interested,
just have a passing fancy... then a scope would be wasted money.  Do
_NOT_ buy some toy out of a department store catalog... if it says
"Tasco", laugh and move on.   If you absolutely _must_ learn it on your
own, consider a new or second hand Astroscan. The Astroscan from Edmund
Scientific is a low power scope, but it is as low a price as you will
find a real scope, and it is so portable that even people that have
several other scopes will often be using the Astroscan just because it is
so _handy_ to carry out to the yard for a quick look.

Consider that the universe went from a situation where the energy
density was comparable or higher than that of matter to a situation
where energy density is much less than that of matter.
This tells us a couple of things. First, that matter must of had an
extremely high temperature and pressure, both of which dropped extremely
rapidly. Further that the matter must have had a lot of momentum
imparted to it by that pressure and augmented by the violent
gravitational tides produced as spacetime expanded.
I think we are staring at the effect of this violent beginning in the
very fact that today we observe a random distribution of clumped matter
even though the universe started out as very homogeneous. The proof it
began as homogeneous was found in the isotropy of the CMBR. The small
anisotropies which are there don't match up with the present clumping.
Perhaps we can use the present state of matter as a good clue to the
explosive origin of the Big Bang by analogy to a small ball of high
explosive. We can make the ball's dimensions and consistency quite
homogeneous throughout yet the shape of the detonation is never exactly
the same twice. This would mean that the explosion itself is or contains
a randomizing influence.
From the evidence we see today, a smooth CMBR and a random distribution
of matter, it can be accordingly argued that the present universe was
born of a randomizing event. With the above analogy in mind, an
explosive BB fits extremely well.
I've heard and read a number of well respected astrophysicists
explicitly use the term explosion or a variation of it. They may have
all been drunk but the odds for such a coincidence are insignificant.

On 28 Feb 98, Keith Knapp wrote to Arnold G. Gill:
     There is no expansion of spacetime between gravitationally bound bodies
(say a stellar system, a galaxy, or even a cluster of galaxies).  Rather, the
spacetime expands, while the rulers and objects retain their fixed values as
determined by the atomic, molecular, and gravitational forces.  There is an
increase in PE when considered on a inter-supercluster scale, but so what?
All that means is that the expansion of the universe (i.e., the "KE") is
being slowed down by gravitational forces.  That result is so obvious it
nearly qualifies as being trivial.

     Not at all.
     Special or general relativity?
     No, no, no!  It can be shown that all of the physical constants have
remained unchanged over the last 10 or so billion years.  Spectral lines,
though redshifted, show exactly the same spacing in quasars as they do in the
lab.  There is no change in the physical constants, there is no change in the
fundamental forces, an atom of hydrogen looks exactly the same now as it did
10 billion years ago.
     Changing physical laws is just a complete non-starter.  All observations
contradict it.  The redshift is a simple effect of relativity, not at all to
do with the changing of constants.

PHYSICS NEWS UPDATE
The American Institute of Physics Bulletin of Physics News
Number 360 February 25, 1998   by Phillip F. Schewe and BenStein
ANTHROPIC COSMOLOGY.  An anthropic argument is one which suggests that
certain physical conditions, such as the oxygen content of the atmosphere or
the Earth's distance from the Sun, are not inadvertently beneficial to
intelligent life, but might actually be especially fine-tuned for life. This
viewpoint has been slow to gain acceptance among scientists because anthropic
logic seems to defy the arrow of time: was not the universe here long before
man evolved? Yes, but there may be more than one universe (as some theories
predict), or the universe we are in may have many domains, each with
different physical parameters.  And we would, according to these arguments,
find ourselves in that domain that had just the right physics ingredients,
just as cold-blooded reptiles thrive only in warm climates.  Physicists at
the Bartol Research Institute at the University of Delaware (contact Stephen
Barr, 302-831-6883)
and the University of Massachusetts (John Donoghue, 413-545-1940) consider
what the anthropic principle has to say not about atmospheric oxygen and
Earth orbit, but about parameters of even more fundamental importance: the
mass of the Higgs boson (the hypothetical particle that endows  all other
particles with mass), the cosmological constant (essentially the energy
density of the universal vacuum), and the Planck mass (the energy
scale---thought to prevail in the very early universe---associated with
gravity, and the energy at which all known physical forces would have been
equivalent).  (V. Agrawal et al., Physical Review Letters, 2 March 1998.)

assistant: You could get a very "primative" 3D effect using exactly the same
technique used by Carolyn Shoemaker when she spotted the famous
comet SL9.  Take 2 pictures of the same region of sky (centered
on the moon or the comet), some amount of time apart.  Relative
to the "fixed star" background, the moon/comet will have moved
between the 2 exposures.
When you view the 2 photos as a stereo pair, the moon/comet will
appear to hover above the background of stars.  "Horizontal"
should be in the direction that the object was moving.  If the
stars are in front, then reverse the stereo pair left/right.  The
moon itself would still appear to be a flat disk, however, and
that's what I meant by "primative".
Best stereo effect depends both on magnification and on how fast
(arcminutes per hour) the object is moving.  For comets, I think
the Shoemakers and Levy routinely separated the 2 photos by
something like 30 minutes.  In the case of the moon, the apparent
movement is about one moon diameter per hour, so 2 photos taken
somewhere between 5 and 30 minutes apart might be suitable.
Hmmmmmm........  For a cresent, quarter, or gibbous moon, the
terminator might actually move enough to change some long shadows
enough to detect in photographs.  Maybe this could give some 3D
effect of the lunar landscape????
