Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Mon, April 28, 2008 - 8:04 AMNice photos but:
The image of the universe is not correct. The universe does not have a single center. There is no evidence to support the idea that any place in the universe is any more the center than any other place. In fact all of our evidence would disagree with this idea. -

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Mon, April 28, 2008 - 1:22 PMYou misread, Curry.
It is not the actual WHOLE Universe; read again under the right image, it says: "The simulation image above is a snapshot of the present Universe that features a large cluster of galaxies (bright yellow) surrounded by thousands of stars, galaxies, and dark matter (web)."
It's a "chunk" of the Universe mapped out in some particular direction (whichever that direction is).
....
There is one more thing they overlooked (or the person who wrote under the image, at least) (well, to my opinion nonetheless) - At this scale, a single star would be too dim to resolve. It says it is a "large CLASTER of galaxies" so we are talking at least a quarter of a billion light years here; thus, we might, (stress "might"), be able to assume that those dots are, in fact, galaxies rather than stars.

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 8:49 AMSerge, You said that I misread and you wrote "...not the actual WHOLE universe
Yet the title states "...ENTIRE UNIVERSE."
And, the images state "Brain Cell" and "The Universe".
So I think that the question remains.
Is this a correct view?
I think not.
The universe is a big place and I am sure that you could find part of it that looked like a brain cell. -

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 3:37 PMCurry,
Read under the right image one more time, I was refering to that. I copied the text (under the right image) exactly into my post. If a chunk THAT big looks this way, then it is safe to assume the rest does as well. This is the meaning of the message. You said that the image was OF the center of the universe, and mentioned that there was no defined center of the Universe for this, this, and that reason, which is entirely correct (at the present stage of the extent of our knowledge about it). The message(s) (up and down) do not state that that is the picture of the entire Universe, they say that scientists discovered that the ENTIRE universe looks like a brain cell (well, a bunch of them), and gives two comparison pictures to prove that, one that of a brain cell, and the other, that of A (ay) cluster of galaxies; and the resemblence is beyond any doubt.
That is the meaning of that.
(unless one would choose to argue 'till he's blue in the face that it looks like the front wheels of a tractor) :)

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 4:36 PMSerge, I am sure that you have seen the many REAL photos that have been taken with our telescopes of as much of the REAL universe that we can see. It does not look like a brain cell. The image of "the universe" shown is not an actual photo of anything.
You wrote "... If a chunk THAT big looks this way, then it is safe to assume the rest does as well. ..." Well all the photos, on a large scale, that our telescopes have taken do not look like the image presented. I would not think that the universe looks anything like a brain cell.
What I wanted to say about the center was that a brain cell has a center while the universe does not. We should consider all of the real evidence and not someone's made up image. Has any of your instructors in any of your classes ever said the universe looks like a brain cell? I think not. All of the evidence we have about the structure of the universe would not be in agreement with an image of a brain cell.
Remember, a made up image is not evidence of anything. I notice that the title does not say that ASTRONOMERS discovered anything.
: ))))) Yes it can be funny. Who's brain is the universe a cell in. -

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 6:11 PMI can't for the life of me find anywhere in the link that it says there is a "center" of the universe, so I do not understand this fuss, and I don't intend to figure out how this could possibly cause such disagreement unless it's an ego thing, in which case I'll be backing away slowly and carefully.

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 7:33 PMOh no Stickboy, you started it. (me lol) No backing away now.
I am saying that:
The idea that the universe looks like a brain cell is not correct.
Because:
A brain cell has a center but the universe does not.
If you want to use the brain cell image, to represent galaxy clusters,
then you would need to say that the universe looks like lots of brain cells.
Still this image will have problems,
because most of the time the stars are not strung out in long thin lines between galaxies.
Plus dark matter has not been mapped to look like this image. It has not been found to be in all these long thin lines.
So this made up image of the universe as a brain cell does not fit the evidence of what the universe looks like.
A better image would be that galaxy clusters seem to be on the surface of large bubbles of mostly empty space.
That is a better fit for the evidence of what we see. -

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 8:34 PMIt is implied that it is composite.
Dark Matter would not be seen on it for, ... well, it is Dark to begin with. It can be detected due to the effects it has on the surrounding ... "stuff". ( www.universetoday.com/2008/02...t-years/ , for example)
Read what he says there again: "... surrounded by thousands of stars, galaxies, and Dark Matter (web)." Now, pay attention to the word in the parentheses -> W-E-B
Now, go up and read the first line from the images up: "... a SIMULATED image of the Universe". Now, pay attention to the word "simulated".
Indeed he should have used a plural form for brain cell((S)). I did it, by the way, in one of my earlier replies.

There is no fuzz. Although, I must admit, it might come out this way.
...
Curry,
The image on the right is a COMPOSITE image of A (AY!) CLUSTER of glaxies that (the images), when combined - infrared, ultra-violet, inverted, etc., etc., etc., types of images creates this picture.
You are thinking linearly. Again/still. We have had this converstation before, cristals, remember? It's like, imagine you are a photon at, say, 650 nanometers wavelength (red specter light). And a, say, gamma ray photon swings by (figuratively speaking, of course) and says hi to you. You ask him who he is, and where is he coming from. He answers, I am from the specter beyond the ultra-violet, my name is gamma-ray. You look at him and say, "You are a lier, there exists only red specter and that is it. Period." No, he says, red specter is only a part of a whole range of colors that are visible (and invisible) to human eyes."
Yet, you keep insisting.
It is a matter of not thinking linearly, that's all. The same goes to the image.

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 7:08 PMI must point out that taking a photo of the universe would not necessarily demonstrate its structure, much like taking a photo of the outside of a building would not necessarily provide insight into how it was created, how it is holding together, etc. -

Re: Physicists discover that the structure of a brain cell is the same as the entire universe.
Tue, April 29, 2008 - 8:03 PMStickboy, nice point even though we can not take a photo of the outside of the universe.
We can only take photos from the inside. Still I think you are correct to say that a photo may not provide insight.
It would only be a limited image. -

This is the maximum depth. Additional responses will not be threaded.
Re: Physicists discover that the structure of a brain cell is the same as the entire universe.

Galaxy Evolution Explorer Celebrates Five Years in Space
Since its launch five years ago, the Galaxy Evolution Explorer has photographed hundreds of millions of galaxies in ultraviolet light. M106 is one of those galaxies, and from 22 light years away, it strikes a pose in blue and gold for this new commemorative portrait.
The galaxy's extended arms are the blue filaments that curve around its edge, creating its outer disk. Tints of blue in M106's arms reveal hot, young massive stars. Traces of gold toward the center show an older stellar population and indicate the presence of obscuring dust.
"We see these arms in optical-light images, but they are very faint and diffuse. These structures really pop out in the ultraviolet due to the exquisite sensitivity of the detectors on the Galaxy Evolution Explorer," said Mark Seibert of the Carnegie Institution of Washington in Pasadena , Calif.
From 24 million light-years away, neighboring galaxy NGC 4248 also makes a memorable appearance, sitting just right of M106. The irregular galaxy looks like a yellow smudge, with a bluish-white bar in the center. The galaxy's outer golden glow indicates a population of older stars, while the blue central region shows a younger stellar demographic.
Dwarf galaxy UGC 7365 emerges at the bottom center of this image, as a faint yellow smudge directly below M106. This galaxy is not forming any new stars, and looks much smaller than M106 despite being closer to Earth, at 14 million light-years away.
Over the past five years, the Galaxy Evolution Explorer has imaged half a billion objects over 27,000 square degrees of sky -- equivalent to an area that would be covered by 138,000 full moons. The telescope orbits Earth every 94 minutes and travels approximately 408,470 million miles per day. Its overarching question is: how do galaxies grow and change over 10 billion years of cosmic history?
"Frankly we have only begun to scratch the surface of this vast data set. Astronomers will be mining the telescope's data archive for the next decade," said Chris Martin, of the California Institute of Technology, Pasadena , Calif. He is principal investigator for the Galaxy Evolution Explorer mission, which is managed by NASA's Jet Propulsion Laboratory in Pasadena , Calif.
M106, also known as NGC 4258, is located in the constellation Canes Venatici. This image is a two-color composite, where far-ultraviolet light is blue, and near-ultraviolet light is red - www.jpl.nasa.gov/index.cfm

M106 is much further away then 22 lyrs. Did you (they) mean 22 Mlyrs? I don't actually know how far away it is. -
