A cosmic exclamation point

(PhysOrg.com) -- VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction. The edge-on galaxy near the top of the image is VV 340 North and the face-on galaxy at the bottom of the image is VV 340 South. Millions of years later these two spirals will merge -- much like the Milky Way and Andromeda will likely do billions of years from now. Data from NASA's Chandra X-ray Observatory (purple) are shown here along with optical data from the Hubble Space Telescope (red, green, blue). VV 340 is located about 450 million light years from Earth.
Because it is bright in infrared light, VV 340 is classified as a Luminous Infrared Galaxy (LIRG). These observations are part of the Great Observatories All-Sky LIRG Survey (GOALS) combining data from Chandra, Hubble, NASA's Spitzer Space Telescope and Galaxy Evolution Explorer (GALEX) and ground-based telescopes. The survey includes over two hundred LIRGs in the local Universe. A chief motivation of this study is to understand why LIRGs emit so much infrared radiation. These galaxies generate energy at a rate this is tens to hundreds of times larger than that emitted by a typical galaxy. An actively growing supermassive black hole or an intense burst of star formation is often invoked as the most likely source of the energy.
Work on the full GOALS survey is ongoing, but preliminary analysis of data for VV 340 provides a good demonstration of the power of observing with multiple observatories. The Chandra data show that the center of VV 340 North likely contains a rapidly growing supermassive black hole that is heavily obscured by dust and gas. The infared emission of the galaxy pair, as observed by Spitzer, is dominated by VV 340 North, and also provides evidence for a growing supermassive black hole. However, only a small fraction of the infrared emission is generated by this black hole.
By contrast most of the ultraviolet and short wavelength optical emission in the galaxy pair -- as observed by GALEX and HST -- comes from VV 340 South. This shows that VV 340 South contains a much higher level of star formation. (The Spitzer and GALEX images are not shown here because they strongly overlap with the optical and X-ray images, but they are shown in a separate composite image.) VV 340 appears to be an excellent example of a pair of interacting galaxies evolving at different rates.
These results on VV 340 were published in the June 2009 issue of the Publications of the Astronomical Society of the Pacific. The lead author was Lee Armus from the Spitzer Science Center in Pasadena, CA.

If the galaxies have a relative velocity of 1000km/s, then they were co-located 420million years ago, just 30 million years after THIS light left the system.
They have likely made a complete blow-through of one another, and are headed back for a second collision by now.
So by now, you have two quasars which are merging to a binary quasar.

This system is 450 million ly distance. That means the light is that old as well.
you're looking at the past.
I picked a number which is within reasonable velocities, but it could be more or less than that.
Regardless, the collision already happened a long time ago.
And so what if I did make multiple posts the past few days?
Most of my comments got 4 and 5 stars, often by multiple people.

Given LaViolette's model, the older elliptical here is naturally the most luminous, containing the more massive (and hence, active) core mother star ejecting newly nucleated matter, which also formed the basis for the younger spiral's eventual development. The growing spiral has likely moved just beyond the range of gravitational influence such that the two may never collide (unlike the other example). Eventually the elliptical may self-destruct as in the other example.
The small less active spiral's core star would permit more stable conditions within the galaxy for the condensation of new matter into stars.
(Laws, are a social idea adopted by science for intellectual convenience. One should remain vigilant for the possibility of exceptions.)
Does this fit the model?

"And I see on another thread you also reject relativity and BBT. Pretty much in science denial?
There are many others here that closely follow your prescription for finding the 'truth'. They advocate for neutron repulsion, AWT, plasma cosmology, anti-gravity matter etc. They all ignore mainstream astronomical conclusions. They apply a (very) little logic. And not so amazingly, they all claim that observations are supporting THEIR theory. They can't all be right.
So how to sort them out? You want to throw out all "mainstream astronomical conclusions" and replace them with what? Scores of poorly thought out, demonstrably wrong qualitative cosmological "notions"."

Tux, that's all you do here. Reject out of hand what current observations are telling us and defer to your hero LaViollette and his nonsense notions.
"Where is your technical counter-point?"
Echoing jsdarkdestruction's post "what's the point?". You've said before you don't have the background to defend his theory. Earlier instances of observations disagreeing with your theory go ignored or the scientists themselves impugned (consensus science, according to another crank here).
Want a technical question? Tell me how you figure the top galaxy in the picture is an *elliptical*? You do know it's gas rich, starbursting, has a substantial(edge-on) disk, and has a bar structure(it's a boxy bulge galaxy: http://www.spacet...eic0914/ ). All the sources I've seen call these a pair of spiral galaxies, not elliptical. Here's one: http://arxiv.org/...52v1.pdf

Well, of course. That's a basic step crucial to understanding how galaxies assemble and evolve. Ever hear of Linnaeus or Mendeleev?
Why not simply stop using these terms(spiral, elliptical, etc) since you don't have a clue?

You, like Oliver and many 'electric universe' people, like to look at images and then try to fit them into your theories, thinking appearance alone is enough to prove your point. Take a look at Figs 1b & 1c (UV images) in this multiwavelength study of Arp 302: http://arxiv.org/...98v2.pdf
If these same 2 pics were used to illustrate this article, would your "story" be the same?
"Relax. Enjoy a margarita. Confusion is bliss."
You, like Oliver, sound quite blissed already.

Thanks for the comments.
The Great Reality that surrounds and sustains us (call it what you will):
Universe, God, Cosmos, Higher Power
Is powered neutron repulsion [1] and illustrated by resentments, anger and violence in the Hindu Goddess Kali [2] in the compressed material at the cores of atoms, stars and galaxies while the universe expands [3].
However, resentments, anger and violence seem to be destructive in the expanded form of atomic matter that comprises humans.

This kind of belief has some side-effects that are preferable to the monotheistic beliefs, because it tends to make them more caring of the environment. Of course, modern India is in the process of economic growth, and is becoming a major source of new GW gases, but that is due to a new generation of Indians. They may be almost as bad as Western Christians, whose beliefs taught them it was OK to "throw the Earth away".

Personally I'm a huge fan of buddhism and zen in particular, and I would consider these athiest "religions", which in a way makes them not a religion in the generally accepted sense of the word. I.e, no superstitious stuff.
Yet at the same time, there are many buddhists who do some really crazy stuff as they believe in all the superstitous junk. I.e... they take things literally, when zen is in a way trying to show you that you can't take anything literally! Madness!
Basically what I'm getting at is - there are idiots everywhere.

Frank, I think you probably ARE wrong! A habitable world's orbit is very delicate, and any disturbance from a nearby system could damage the system, and either eject the planet from its Goldilox zone, or lead to excessive bolide impacts (possibly by disturbance of the equivalent of the Oort cloud).

The anger, resentments, and violence of the Hindu Goddess, Kali, is remarkably like the interactions between neutrons confined in compact objects.

I read "the Tao of physics", and to be honest it got pretty ridiculous. I'm still a big fan of using zen to interpret existence, and sometimes the thought patterns overlap quite well, but one must be careful not to read too much into these things.

Above you posted:
"Whatever the classification of the topmost galaxy, it seems self-evident from the photo that it has grown larger in mass than the lower, with an almost circular halo at this point. It seems on it's way toward growing more massive into an elliptical."
Again I ask, take a look at Figs 1b & 1c (UV images) in this multiwavelength study of Arp 302: http://arxiv.org/...98v2.pdf
Still think the galaxy at the top has grown larger in mass than the lower? Based on what? And, is it still on its way to growing more massive into an "elliptical" (your words)? Based on what observations of Arp 302?
And in the original image, how do you know the galaxy at the top is more massive as you claim? Do you have any citations backing up any of your above claims wrt Arp 302 whatsoever or is it mere speculation?
There's 3 more "technical counter-points".....what say you?
