It is wonderful to see the images which the Hubble Space Telescope
provides -

http://www.sciam.com/gallery_directory.cfm?photo_id=8153DC82-A24D-3D07-8B32672098BE3984

Perhaps many decades from now it will be possible to talk about
galactic collisions in a normal and adult way but there is nothing
normal about this era.

After looking at the images and putting them into a broad context,the
same people will t talk about the expanding space and galaxies flying
apart from each other in order to satisfy a seperate empirical agenda
of the 'big bang'.They create a story without the slightest hesitation
even though images showing that these huge stellar islands can
collide with space having the same background for the occurence of
all objects in motion.

At least I get spared the vacuous explanations where the galaxies are
considered to be flying apart for billions of years yet images show
them colliding or a seperate explanation where galaxies are explained
as colliding and forgetting about cosmological evolution in terms of
the 'big bang'.

Amazing images ,just needs astronomers to appreciate them in context.

Are you being wilfully ignorant, or do you only have space for a single
concept in your head at one time?

You are a disgrace to intellect.

Stow it mate,half the people in here would love to escape the junk
dumped into the celestial arena .If somebody wants the 'big bang'
theory where the galaxies have been continuously flying apart while
observationally seeing galaxies collide or interact then the
'expanding space' junk and the reasoning behind it has to go.

Now is the time for people to speak up and express their views without
fear of offending some numbskull who is merely a clone for useless
empirical junk,try it,it is refreshing and liberating.

It is taught that space has expanded 13 billion light years,the
further we look out the further back in time we are supposed to see.I
had to laugh a few weeks ago on the Bad Astronomy forum where a
curious creationist was playing along with the spiel of expanding
space and many tripping over themselves to explain it to him.He then
asked does that mean that the Universe is 26 billlion light years in
diameter and thereby setting off seizures the proponents of big bang
geometry to talk abouit something else,it was one of those 'out of the
mouths of babes' type things which can be enjoyed on occasion.

 In that case you are setting up a strawman argument. It's
been known that galaxies have 'peculiar motions' since the very early
days of velocity measurements of galaxies.


It is not about being sucked into an argument,it is more or less
decending to an intellectual level of a flat Earther and excuse me,I
do not wish to dishonor human intelligence by doing so.If you want to
believe 'every valid point is the center of the Univerese' then good
for you,the idea was so distasteful to Christians that it actually
provided the background for the emergence of Copernican heliocentric
reasoning .To borrow the argument -


"Suppose person A were on the earth somewhere below the north pole of
the heavens and person B were at the north pole of the heavens. In
that case, to A the pole would appear to be at the zenith, and A would
believe himself to be at the center; to B the earth would appear to be
at the zenith, and B would believe himself to be at the center. Thus,
A's zenith would be B's center, and B's zenith would be A's " Hence
Cusa could write in the early 15th century -

"And wherever anyone would be, he would believe himself to be at the
center.Therefore, merge these different imaginative pictures so that
the center is the zenith and vice versa. Thereupon you will see--
through the intellect, to which only learned ignorance is of help--
that the world and its motion and shape cannot be apprehended. For
[the world] will appear as a wheel in a wheel and a sphere in a
sphere-- having its center and circumference nowhere. . . " Nicolas of
Cusa

I often use the story of a reluctant skipper driving in a car and
sticking his hand out the window and determining that it was blowing a
gale of wind despite the fact that the car was travelling at
50mph,back to the pub boys !.Contemporary guys who wishful think the
big bang into existence via celestial sphere geometry ultimately try
to do the same thing with inevitable and sometimes unintentionaly
funny results.

It is not a matter of intellectual honesty or dishonesty,I am from
the 21st century and imaging and time lapse footage is so powerful
and the original astronomical texts are so easy to put your hand
on,that I can forego the usual descent into insult throwing ect. and
hope that an astronomer will eventually catch on to an incredible
astronomical paradise beyond the novelstic junk that obscures it.

One of the junk concepts is this idea of expanding space where the
galaxies fly apart yet observations show them interacting like any
other objects do.I do not have any attachment to big bang geometry and
the reasoning behind it,so I am free to look at cosmological evolution
from a closer perspective and especially stellar evolution.without
having to make any great sweeping conclusions about how the universe
began or if there are any great structural motions beyond galactic
rotation,things like that.

I reiterate, you expose yourself as a fool by your arguments.

How about this theory
"Everyone gets older until they die"

Does the presence of a baby invalidate the theory? No - of course not,
because as well as ageing, there are other processes going on.

Similarly, as well as expansion there are other processes going on,
notably gravitational attraction between galaxies in clusters - so
'galaxies in collision' is of no surprise to anyone other than the
bewildered.

This pretty well sums up the limitations of your approach. Strange that

I have to laugh at the expanding balloon universe where all the
galaxies have been flying apart for billions of years and the
reasoning behind it -

http://encarta.msn.com/media_461533130/expanding_universe_experiment.html

When people see galaxies interacting and evolving in a normal
way,there is no real need to appeal to a huge sweeping notion of a big
bang conclusion unless you really want to expose yourself as having
very poor judgement to say the least.

I would have to descend to the intellectual level of a flat Earther
to even begin to contend with somebody who envisages a 'expanding
balloon' Universe,others may be fooled into believing that there is
some substance in the reasoning but how they do this while watching
galaxies interact I do not know.

I enjoyed how the creationist unwittingly stated that if distance
equals time and cosmologists look acxross 13 billion years of distance
then the Universe must be 26 billion years old in terms of a
diameter.I thought it was priceless even if it was unintentional but
then again,people have shown themselves to have an addiction to a
celestial sphere framework and the reasoning behind it.

Don't be sour,enjoy your 'every-valid-point-is-the-center-of-an-

Images of galactic encounters, of the worse possible kind.
The best of 59 examples of cosmic hell busting lose, not that many
other than these relatively old Hubble images of the anti-big-bang
exist. Each of these galaxies has a fairly horrific gravity/tidal
radius of several thousand light years (perhaps at least as great as
64r, if not 128r), not to mention the mutual attraction of whatever a
pair or more of these bad boys has to work with, whereas you might
like to further reconsider the mutual gravity/tidal binding grasp of
two or more such encounters is perhaps worth 4X the individual tidal
radius. (hard to avoid gravity, especially when it’s the only game in

Rogue stars, spare planets and those pesky icy proto-moons have
existed and most likely still exist, as somewhat cosmic encounter
created on the fly (so to speak). It’s likely where our passive sun
came from, as well as for a few of our planets and associated moons
that don’t seem to fit the Old Testament interpretation as the one and
only holy grail of what’s mainstream status quo, or bust.

Tidal binding force of a given solar system is rather impressive, but
almost nothing compared to the cosmic tidal binding force of entire
galaxies that host such SMBH cores in addition to all else combined,
and especially offering an extended tidal grasping reach between those
galaxies mutually attracting upon one another.

Pluto = 2.125e-3 earth = 1.27e22 kg (not including it’s three
planetoids/moons)
Pluto average distance = 5.91352e12 m
Avg. orbital velocity = 4.74e3 m/s

Centripetal Force = Tidal Binding Force(TBF) or Binding Energy(TBE),
is the same exact worth as the following.
http://www.mill-creek-systems.com/se/SEGravity.htm
centripetal force = 48.2519e15 Newtons/sec (10.848e15 lbs/sec)

http://science.nasa.gov/headlines/y2005/01nov_moonsofpluto.htm
“These are tiny moons. Their estimated diameters lie between 40 and
125 miles (64 and 200 kilometers). Charon, for comparison, is about
730 miles (1170 km) wide, while Pluto itself has a diameter of about
1410 miles (2270 km).”

Even Sedna at its furthest reach and of such little mass hasn’t a
chance at escaping the mutual binding worth of tidal grasp without
help, at least not until our Sun as consumed much of itself, having
gone into its red giant phase, thus leaving behind a mere spent brown
dwarf of a sun that hasn’t sufficient mass to even hold onto the likes
of Earth, much less Sedna.

Before the supposed singular SMBB, there was supposedly just our one
and only SMBH (aka God fart or Semitic Massive Black Hole) surrounded
in all possible directions by less than one messily atom per cubic
light year, and supposedly without any other dark matter, dark energy,
photons or gravitons anywhere in sight. (ideal faith-based mindset)

OOPS!, talk about cosmic shrinkage and having another one of those bad
God days. Here’s a few faith testing images of galactic encounters,
of the worse possible kind. (a series of God oops resets, as recorded
by team Hubble)

The best of 59 examples of cosmic hell busting lose, not that many

and that of Andromeda? (1024r?)

mutual tidal grasp of 2e20 N at better than 60r, and our Sun/Pluto
average tidal reach is obviously worth 10,060r, not to mention
whatever Sedna might suggest. Obviously, if this mutual tidal radius
of binding force wasn’t there to behold, we’d be losing our grip on
such wussy little items as Pluto and Sedna, especially when our solar
system trekked anywhere near the 3X solar mass of Sirius would become
capable of adding or subtracting items (aka cosmic foreign exchange,
so to speak).

notion for going on a millenia as the reasoning of Nicolas of Cusa
shows,the fact that you embrace it speaks for itself.

Please let me point out that Nicholas of Cusa, a great philosopher
and an originator of the "Cosmological Principle" that the physics
of terrestrial and celestial bodies are similar, presents fascinating
geometric paradoxes as a method of spiritual contemplation, with
"every valid point is a center" as one quite possible conclusion.
Thus he says: "Hence the world-machine will have its center everywhere
and its circumference nowhere, so to speak...."

He explains that a person on the Earth, the Sun, or another star (with
the benefit of our later knowledge, we might Mars, say, and an extrasolar
planet for the latter two situations) will always consider that as "the
immovable center" so that "all other things were moved."

I see no incompatibility at all with an expanding universe, nor with the
idea that despite the global expansion, as noted by Hubble, we sometimes
see blue shifts which indicate that some galaxies (e.g. M31, the Andromeda
Galaxy) are approaching rather than receding.

Cusa is fascinating reading for the concept of relativity which Galileo,
Newton, and ultimately Einstein would develop further.

"For example, if someone did not know that a body
of water was flowing and did not see the shore while
he was on a ship in the middle of the water, how
would he recognize that the ship was being moved?"

This is precisely the kind of argument that Galileo uses in his
_Dialogue Concerning The Chief Two World Systems_ (1632) almost
two centuries later.

Anyway, having emphasized Cusa's vital and all too infrequently
noted role in the development of some of the greatest ideas of
astronomy and physics -- he has a fascinating discussion in his
_De ludo globi_ or "Game of the Sphere" (a kind of bowling)
about impetus which proposes something close to Newton's
First Law -- I want to stress that the "center everywhere,
circumference nowhere" concept is precisely in his own words,
words which had been used in theological tradition to describe
the Deity and which he applied to the universe also.

By the way, I read Cusa's scenario you quoted with the center
and circumference alike "nowhere" to mean that there is no
_privileged_ center, although any point may be a relative
center for someone located there. The two passages don't
seem to me to imply any necessary mutual contradiction: maybe
more like "no point is an absolute center, and every point is
a relative center."

I realize that this is tangential to observational astronomy,
but do want to clarify these points for anyone who might be
curious about a truly great philosopher.

Most appreciatively,
