Mysterious MilkyWay Warp Finally Explained?
* * Beatles-Beatles writes to tell us Space.com is reporting that scientists think that a collision between mysterious 'dark matter' and two of the Milky Way's nearby neighbors may be causing our galaxy to warp 'like a vinyl record left out in the hot Sun.' From the article: 'The warp is most clearly visible in a thin disk of hydrogen gas that extends across the entire 200,000-light-year diameter of the Milky Way. Viewed sideways, one half of the hydrogen disk appears to stick up above our galaxy's plane of stars and gas, while the other half dips below the plane for a bit and then rises upward again farther away from the galaxy's center.'"
Now if only we could get that hydrogen disk into some fuel cells...
And I always thought it was something in my eye!

Wow. A Slashdotter, a Slashdot "author" AND a space website conspiring to spam us...*sigh*
There was a related article in November-- with evidence pointing towards a massive black hole at the center of the LMC. (The Milky Way's closest neighbor)

The warp is most clearly visible in a thin disk of hydrogen gas that extends across the entire 200,000-light-year diameter of the Milky Way.
Thin Disk? Next thing science will be telling us is that the sun doesn't revolve around the earth, and the earth is round.
The theory of relativity doesn't work right in Arkansas.
The article fails to say (or perhaps I missed it?) how severe the warp is nor how fast the warping is happening currently. Furthermore, it doesn't say when this warping was first recorded.

Yay, I have a sig.

Now, hold on... I'm not suggesting that we jump ship.
All I'm asking for is Journalistic integrity.
I know digg exists. I deliberately come back to slashdot. The reason? I'm not here for the articles. I'm here for the discussion. I can get the information anywhere. I am at slashdot because I want to know what others think. There are some very smart and very connected people on Slashdot, and I value their opinion. I also find out about alternatives or other theories or random_x piece of software I didn't know existed from the comments. I consider it a great day when I see someone say "Well, if you like X, you'll love Y". That to me is slashdot's strength. And I try to contribute positively where I can.
All I am asking for is for the Admins to have a little integrity. Whatever happened to honesty? Whatever happened to shaking a man's hand, looking him in the eye, and telling the truth? I'm that kind of guy... so are many of my fellow Slashdot readers. And I have an almost irrational belief in the fundamental "goodness" of mankind.
If I had to nail down the problems of Slashdot these days, it's very simple:
1.) They don't hold their admins to the same level of integrity to which their readers hold themselves.
2.) They irrationally refuse to believe people like me exist; they refuse to believe that the strength of Slashdot is in the content provided by the readers.
But, one at a time. Let's get 1 working first, and then I think 2 will fall into place.

All I was pointing out was that the fact that 800,000 people have signed up since me, and that I've been here 5 years; the fact that I've been contributing positively (I had 50 karma long long long before karma went to the bill-and-ted system), the fact that enough people respect my opinion that I have over 130 fans (of which I'm very proud and greatful; see my journal on making fans friends), the fact that I still have my complete A-Z archive of Geeks in Space, and that I listened to it from the very first one - I think all these things entitle me to at least ask these questions.

Now that's what I call an extended LP.
Wired is crap these days. All that I see out of Roland on his blog is just resummarizations of articles out of magazines and other websites. Up until recently, he was comitting plagarism by not mentioning his sources.
There is also the question of the French TDA company that Roland appeared to have some relation with while he was touting their devices and offering demo units to people who paid for them. People who put money down for them never got their TDA and the company just vanished.

You make some good points, but I think you make some assumptions.
You said you've only submitted ten or fifteen articles to Slashdot in your entire lifetime. To contrast, I wouldn't be surprised if Beatles Beatles submits at least fifteen articles every week. (He makes money off of it, so it's worth it for him to spend a couple hours every week trolling the Internet for stories.) If that is the case, his success in getting articles submitted would be perfectly sensible.
That said, the fact that the person who posts his articles is consistantly ScuttleMonkey is intensely suspicious. It is possible that there are other reasons, but we are right to be suspicious.
That said, I'm not sure if we are right to care. It's not a big deal. Beatles beatles's articles are generally neat little links.
The sole function of editors at Slashdot is to prevent stuff like Goatse from getting posted. In the years I've been here (less than yours, admittingly) editors have never done anything vaguely editorial. All they do is look in the editor's queue, and post whatever catches their eye. They do not edit the posts for grammar, or check if the article has been posted before, or check if the article is true or not. They are not journalists, they are merely a rudimentary filter. Thus, until Beatles Beatles posts Goatse, ScuttleMonkey is performing his job perfectly.

Digg was designed by some talented people, but Digg is inhabited by incorrigible dunderheads whose comments are digital bumfodder.
The strength of Slashdot is its discussions. If you think that TFA is crap, I entreat you to peruse the One-Eyed Cat With No Nose article on Digg.
The rumours of Slashdot's death are greatly exaggerated and largely promoted by members of the Digg crowd, with the occasional assistance from Slashdotters who insist on presenting us their own damnably clever variations on the themes of Beowulf, Soviet Russia, and the welcoming of Overlords.

Here's the abstract for the presentation by Leo Blitz on the warp. Anyone who was at the AAS, knows someone who does or understands dark matter professionally, how about telling us if this tablecloth fluttering mentioned by Blitz in TFA might be useful as a test of dark matter? Abstract follows.

[40.05] The Shape of the HI Warp in the Outer Milky Way Disk
E.S. Levine, L. Blitz, C. Heiles (UC Berkeley), M. Weinberg (University of Massachusetts, Amherst)
Although the warping of the disk of the Milky Way has been known since 1957, our work represents the first time the Milky Way warp has been quantitatively described and we find it to be both elegant and surprising. We examine the outer Galactic HI disk for deviations from the b=0 plane by constructing maps of disk surface density, mean height, and thickness. We find that the Galactic warp is well described by a vertical offset plus two Fourier modes of frequency 1 and 2, all of which grow with Galactocentric radius. The global warp demonstrates approximately an order of magnitude more power in each mode with azimuthal wavenumber m=0,1, and 2 than in any higher frequency mode; thus three and only three modes are necessary to describe the large-scale behavior of the warp. The power in the m=0 and m=2 modes grows starting from around 15 kpc; the m=1 mode is the most powerful everywhere in the outer disk. We outline six observational conclusions regarding the warp that any potential theoretical mechanism must satisfy. We will also show a movie that demonstrates the evolution of the three modes with time.

I guess one *could* call it "explained", although involving this "mysterious dark matter" is much like explaning how the Sun can shine as "we now know the Sun get fueled by some mysterious nuclear process".
This explanation only highlights our problems with dark matter even more, and things get especially funny if it's later discovered if it didn't exist. Then watch a number of theories fall apart during a night.
Beware: In C++, your friends can see your privates!
I'm jumping ship. Slashdot is a good time waster, but a bit redundant IMO (anything major I'll hear about, anything that interests me I can go elsewhere to read about, like Digg). It's shit like this that keeps on happening over and over with no care taken. I have better things to do with my time.

I think the implied objection is that you feel this fellow is profiting from net traffic that is the result of a special relationship with ScuttleMonkey. If the articles that are posted are topical and of interest, and certainly there are many postings on the topic of cosmological and astronomical facts, I think you have not much leg to stand on.
If the articles were irrelevant tripe, that is a different matter. You threw out your own judgement about the relevancy or the derivativeness of this fellow's particular postings, but choosing posted topics is not really a democratic process: you are not given the power to mod the topics, but you can mod the resulting discussion.
Which means you are trying to do what you have not the power to do and you are doing it by posting off-topic comments which is actually more objectionable according to the "rules" than anything. If I were you, I would be happy that you received enough community support for your opinion that you were modded up despite being off topic, :-).
Perhaps for amusement, you could try writing your own article about the inequities of Slashdot topic selection and then submit it for consideration as a posted topic. That would be a hoot. Imagine if they actually posted. Hard to argue about integrity in that case.
Anyway, cheerio. I understand your beef. But this is how far you get bitching at the establishment, even a good spirited open-source friendly one: 0 meters. Although, if the galaxy warps enough there could be some error in that measurement and you might actually make some progress in a billion years!
What conclusion am I to draw?
/. plays favorites?
/. is taking money to greenlight articles?
That
That wouldn't surprise me one bit. You know, the world isn't fair. Does it guarantee somewhere in the slashdot charter that slashdot will be fair about approving submissions?
Or are you accusing that perhaps someone at
If so, just come out and say it.
Personally I think it's a stretch, I just don't hold slashdot in high enough esteem that it would be worth paying to get articles like this on it (unlike crappy "comparo" articles).

Why can't there just be no dark matter at all?
To be honest, the whole idea of it and how it just "has" to be there to make observations fit the theory just reminds me of how convinced scientists were of the existence of aether before the Michelson-Morly experiment in the late 19th century.
File under 'M' for 'Manic ranting'
The additional mass and friction with dark matter is not only causing the milkway to warp like a record in the sun but also results in the milkyway playing at 45 speed unlike other LP class galaxies that naturaly travel at 78.

I lost mod- and meta-mod privs (literally) years ago. A while later, I realised that my meta-mod privs had returned; as far as I know, I still don't have my mod-privs back. I guess I *could* have missed the points, but as I tend to browse the site a couple of times a day every day it seems unlikely...
I think the trick is to not take this site too seriously. We rant and rave about adverts and uncaring big business, all the while being advertised at in obvious and not so obvious ways by a business that while not very big, certainly doesn't give any impression of caring.

With the disclaimer that I work at Digg, what makes you think Digg lacks what Slashdot gives you? At first I lamented the fact that Digg, although cool for its front-page articles, has really crappy comments.
But lately, when I go to a Dugg story with a lot of comments, and read at +1, I get a couple of nice gems.
Plus, Digg gives me a lot more variety. As a many-year Slashdot reader, I'm actually starting to di-- uh, like the website.
Again, I know it's kinda hard to swallow since I'm supposed to be all biased and stuff, but I swear I'm not. It took me several weeks of using Digg before I finally decided I could actually eat my own dogfood.

it's a blue bright blue Saturday hey hey
a spectroscope breaks the star light through a prism and displays black lines going through one of the colors
No, a spectroscope breaks light down into its spectrum - the discrete frequencies* that make it up. The black lines are there because those frequencies are missing. For example, if you took a pure red light source and put its light through a spectroscope, you'd have a narrow line at the appropriate frequency, and black everywhere else. The lines themselves have nothing to do with redshift (or blueshift), and aren't "put there" by the spectroscope.
(* discrete here meaning to within the tolerance of the device, we can't measure arbitrarily narrow frequencies so it'll always be a (thin) range)
You measure the speed of the source of light by comparing the observed pattern of lines with the expected one. If the lines are shifted higher in frequency (towards the blue end), the source is moving towards you; if they're shifted lower in frequency (towards the red), it's moving away from you.
That presupposes that you know what the spectrum is supposed to look like, of course.
well, if light can be attracted by gravity, obviously the speed of light is not a constant
That's not obvious at all. A sattelite orbiting the earth at a constant altitude is travelling at a constant speed, yet is constantly attracted by gravity. I am currently travelling at a constant speed (zero, wrt the Earth) yet am attracted by gravity. Similarly, light being bent around a massive object is attracted by gravity, yet travels at a constant speed.
Now, perhaps it's "obvious" that light being "sucked in" by a black hole speeds up as it approaches, but that's not the case either. It also doesn't stop when it hits it - it's absorbed, and is no longer light.
we still do not fully understand the nature of light, although many people think they do. (many people say "light travels at 186 miles per second." and it seems noone knows the end to that statement to actually make it scientific. "light travels at 186 miles per second IN A VACUUM."
It's true that we don't completely understand the nature of light, but we're not as clueless about it as you seem to think. We've been observing it and experimenting with it for hundreds of years, and we have a pretty good handle on how it behaves.
Also, assuming that your "many people" refers to the general public rather than the physics community in general, well then I hate to break it to you but most people are utterly clueless about science. For example, while you correctly point out that c is the speed of light in a vacuum, you yourself get it wrong - it 186000 miles per second.
we do not know that throughout space that the speed of light has remained a constant
No, we don't. Equally, we don't know for sure that the laws of physics are the same everywhere, or that they'll be the same tomorrow as they are today. You have to start with a working set of assumptions, though, and so far we don't have much evidence to suggest that we're wrong. If we find some, great - we'll have to change our theories to cope, and lots of interesting work will be generated. If we don't, great - we can get on with newer, just as interesting stuff. Science is win-win like that; even if your theory proves to be wrong, you've contributed to the greater understanding.

What do you mean by "evolutionist professors"? (The phrase rings an alarm bell at the back of my mind...)
8.4 -> 10.6 is what, 25% error margin? seems a bit far off from an exact science to me
The Hubble constant is not well understood and is very hard to measure, hence the error margin. That is the way of things, however - initial estimates tend to be out, but over time as the problem is better understood and theories are developed, they get closer.
How can you -estimate- a constant, since that number is one of the multipliers in your equation, if even one num

BTW, I dont fully understand how search engine indexing works, but wouldn't everybody in this thread constantly mentioning "Beatles" and referencing their songs (even while complaining about Scuttlemonkey and spamming) increase the relevance that google attaches to this guy's link in relation to the Beatles, and rise his page up through the ranks?
Yeah, ok, pure psuedo-science.
(probably just a typo, but you don't really think light travels at 186 miles per second, do you?)
The acoustic doppler effect you labor on about is a simplistic model that may help the layperson grossly visualize concepts like em redshift, but it should not be assumed that a remotely similar process is at work when considering topics like stellar spectroscope shift. Audible sound represents a compression wave which propogates through a medium; electromagnetic energy does not. It can interact with matter, but it exists as a separate entity and is not a mechanical process. While field equations share some fundamental aspects with wave mechanics, this does not make them the same thing. Mathematically, there are many instances in nature where similar functions and constants are "re-used"; and generally one can simply attribute such similarities to thermodynamics (i.e. if stars were naturally square, this would violate the laws of thermodynamics).
While inter-stellar distance calculations based on stellar spectroscopy are certainly capable of being inaccurate for a number of reasons, the science behind these is based on a number of core principals wherein the speed of light is largely irrelevant for determining that the model fits (in one form or another):
1. Spectroscopy: A well studied, deterministic science with which one is capable of determining elemental components based on electromagnetic frequency distribution. The spectroscopic fingerprint is "hard"; e.g. there exist no in-between spectroscopic gradients between two elements, any more than there exist magic elements "in-between" those identified on a periodic table.
2. Red-shift occurs when an emitting object is receeding from the reference frame of an observer. This has been demonstrated experimentally and is reproducible.
3. Intersteller objects which are known to be receeding via parallax measurement exhibit redshift. Their spectroscopy

You seem to be as bad as Slashdot, if not worse, when it comes to ignoring the community. How long have people hollered for threaded comments? How long have you left the security holes unfixed? When a story gets submitted that shows the auto-digg feature, you delete the story instead of fixing the problem.
The problem with the moderating is that hardly anybody does it. If I browse Digg at +1, there are hardly any comments, and a lot of worthwhile comments remain stuck at 0 forever. Plus the mod options are pretty damn stupid - not just for the comments, but for the stories as well. Where's the "Report" option for "Has nothing to do with technology, get this crap away from Digg"?

Wow! The think I immediately noticed, on my next visit to slashdot, was that ScuttleMonkey is doing nearly all of the work! Turning off his stories results in a page that looks like it's full of dupes ... but they are not dupes, they are just the few stories from yesterday that were posted by anybody besides ScuttleMonkey.
Secession is the right of all sentient beings.
A sattelite orbiting the earth at a constant altitude is travelling at a constant speed, yet is constantly attracted by gravity. I am currently travelling at a constant speed (zero, wrt the Earth) yet am attracted by gravity. Similarly, light being bent around a massive object is attracted by gravity, yet travels at a constant speed.
These are fairly specific instances though - an orbitting body only orbits at a constant speed if it's orbit is perfectly circular. Take a look at comets as an example, which have very eliptical orbits around the sun. Comets travel at relatively slow speeds for most of their orbit but are going very fast as they pass close by the sun. In your other example, you are travelling at a constant speed (zero) because the ground is producing a force opposing gravity - take away the ground and you'll accellerate.
Light is a rather strange beast - normal matter changes speed when energy is applied to it whereas light changes wave length (shorter wavelengths are higher energies).
Some clarification for the grandparent: light travels at 186[000] miles per second IN A VACUUM.
My understanding is then when you're not in a vacuum, light still travels at 3x10^8m/s in the spaces between the matter but whenever it hits some matter it gets absorbed and then re-emitted which takes some time. This means that during the times when the light isn't travelling at c it isn't light.
The Hubble constant is not well understood and is very hard to measure, hence the error margin.
Didn't someone determine that the Hubble constant is infact not a constant? Can't really remember but I have a vague idea that I'd read something about it.

So...a mysterious warp that we can't explain may be explained by something ELSE we can't explain!? Guess the only thing constant is change. Hey, today it's a tree tomorrow it's a dog!

Um, the topic is the shape of our galaxy. The Hubble Constant is utterly irrelevant to this topic. The very fact that it appeared here is a sign of total cluelessness.
It's true that the galaxy's size and shape was mostly determined by measuring distances and relative motions of various things within the galaxy. But these motions are unrelated to the universal expansion that the Hubble Constant is a measure of. The galaxy isn't itself expanding.
Those who do study history are doomed to stand helplessly by while everyone else repeats it.

Conspiracy theories again run rampant as users accuse Slashdot Editors of being in cahoots with scam artists. Sounds like just a normal day at the office for me. Except that I've decided to say a few words on Slashdot article selection process and users who try to abuse it. Read on for my rant.
http://slashdot.org/article.pl?sid=06/01/10/14402
I remember the "Post of Doom" - a post that complained about something or other which was immediately modded to oblivion by an editor (Michael). The post was then remoderated back up to +5, down to -1 and so on until the post had several hundred moderations. Not to mention all the posts (hundreds in the end) that supported the post and were asking "WTF?" getting modded down, and up, and down. There must have been thousands of mods on that thread that day - IIRC I don't think I've ever had mod points since then.

I just looked over his site http://www.george-harrison.info/ and it looks legitimate and not like a link farm. Just to be sure I went and looked at the site in the google cache, but it still looked okay to me. However there is a lot of upset here (and if you ask me: yes, there is definitely something fishy going on with ScuttleMonkey posting such a slew of * * Beatles-Beatles submissions) Maybe I am missing something here and in case he's guilty, this is where you report him: http://www.google.com/contact/spamreport.html To their credit Google takes these reports seriously and investigates them.

Posted the above rant before I saw CmdrTaco's article on this topic. Feel free to mod my comment off-topic.
Q: What the hell do the beatles and science have in common? A: Entymology. m
Wasnt there a story a couple of months ago about dark matter not existing? I am not sure whether i believe that, though it sounded plausible.
a rk_matter_sidebar_010105.html
(The article was about that the classical approximation just wasnt good enough, the mass came out correct without dark matter with general relativity.)
But when some mass is missing in the estimates, it seems like that mysterious "dark matter" of which we know _nothing_ is blamed, just stuff some of that where your missing mass.
Here a quote from when you click through darkmatter:
http://www.space.com/scienceastronomy/astronomy/d
"By measuring these mysterious effects of gravity, researchers determine how much "extra" gravity is present, and hence how much extra mass, or dark matter, must exist."
Thank you for making my point space.com (i know maybe not the most scientific source, but gravity really is the only way to measure "dark matter" currently)
By the way dark energy isnt so vague, i am convinced that that exists.
also how did they simulate the dark matter?
Here's a clue bitchwipe:
1. A man can love a man
2. A woman can love a woman
3. Anyone opposed to these facts deserves to die
Forward to clue 2:
1. The CIA put Saddam in power
2. Then they bitch up a storm when he refuses to be their puppet
3. They declare war simply because their oil stocks are at stake
4. We go there multiple times since 1991 and STILL haven't solved the problem
All the money spent since 1991 on war, could have been put into weaning ourselves from fossil fuels. Kill the oil industry and the problem in the middle east will go away.

I lost mod- and meta-mod privs (literally) years ago. A while later, I realised that my meta-mod privs had returned; as far as I know, I still don't have my mod-privs back. I guess I *could* have missed the points, but as I tend to browse the site a couple of times a day every day it seems unlikely...
Actually, in CmdrTaco's defense, I think that's how Slashcode works. If you browse the site "a couple of times a day" it might consider you too busy to receive mod points. Somewhere in the FAQ it mentions that you won't get mod points if you spend all day reloading the front page -- and you won't get them if you only read it every six months.
When I go on a posting binge (as often happens when a story comes up about an issue I care about) I can easily reach 30 or 40 comments in a day. After that it seems that I don't receive mod points for awhile.
Today when I logged in I had five mod points waiting for me -- I hadn't posted in awhile and only read the site a few times over the last week or so because I've been busy.
I want peace on earth and goodwill toward man.

Speaking as a low-5-digit ID, the whole ScuttleMonkey + BeatlesBeatles shit makes me want to get the (fixed) slashcode that runs Plastic and make a Slashdot2. Moderated submission queues + writeups (no need for editors), karma systems that work, etc. Not like Plastic doesn't have its issues, and some days I'm surprised that Slashdot actually works at all, but I don't even read stories anymore. Just comments starting at +2.

Get over it. I have a high user ID because I browsed here forever before getting one. And you know what? I've submitted only a few topics and have been surprised that some were so readily accepted. I think the way the article is submitted has far less to do with it than the nature of the referenced article itself. If it's an interesting topic that fits with the general focus of Slashdot topics, I don't care who submits it. (Maybe because I almost never bother to check out their own sites or links anyway.)
This space intentionally left blank.
The minute Digg gets a threaded comment system remotely as usable as this one, it's goodbye Slashdot.
I doubt it. The volitile nature of Digg means that truely insightful discussion may become lost amid the torrent of new stories filtering up through to the front page. I very much doubt threads on par with the bets slashdot discussions will ever bee seen on Digg.
That said, **Beatles Beatles is the definitive argument against the editor system.
May the Maths Be with you!
Don't even bother emailing Rob Malda. His responses are usually sarcastic and jerky.
Just to throw in my own two cents, the one time that I emailed Malda about a bug in the site, he was very responsive and courteous.
I think he's a perfectly nice person, and a reasonably talented geek, just not much of a journalist. Then again, I don't think he wanted to be one. It just sort of happened.

I have been a long timer too (1999 I think).
First it was Roland Piquepaille pushing articles to his primidi site, then it was Carl Bialik from the WSJ pushing articles from the WSJ, and now it is ** Beatles Beatles linking to his George Harrison site.
I am bothered by Slashdot favoritism as well, but more so by the lack of any mechanism of feedback and the deaf ears it falls on. Any site would have a forum/topic for comments from users.
When I commented on this last October, I lost mod privileges, which used to be every few weeks for the last few years.
Today, CmdrTaco posted something on the topic, which I have yet to read. Not expecting any break throughs though.
This site is about a) the vast readership, b) the superior threading/threshold and c) the comments.

I mean, okay, in theory it's off-topic to talk about something that isn't the article; but where else on Slashdot would one talk about Slashdot? All that really exists here is random articles and people commenting about them (yeah, yeah, there's diaries, but that's hardly where most of the talking goes on, and saying that people can complain there is like saying they can protest anywhere they want as long as it's in a designated protest area).
/. as a "big public wanking session" is here, interesting at least as context and certainly as far as seeing what The Big Guy In Open Source has to say about, well, what everyone is talking about in this thread.

And screw it if it's off topic, he does reference an interesting post by Linus, and personally I'm quite okay with "off-topic" if it also means "nonetheless very interesting"! (But I have to say, CmdrTaco's post is somewhat convincing).
Take a wider view here. Slashdot has alot to say about Linux, really, all the time, and arguably Linus is the most important single person in that area. So mentioning something that he says about Slashdot itself is almost more on topic than a story could even be!
For the record, the page where he describes
Of course, go ahead and ignore what I say, since I guess (finally re-checking the RSS feed) that I was too late in writing this, and that there already is http://slashdot.org/article.pl?sid=06/01/10/14402
I remember sigs. Oh, a simpler time!
Just a though...
So, the shift tells us if an object (light source) is moving towards or away from us. Did not an Einstein prediction also involve light being bent by a heavy body and bent more the heavier the body? If this is true and the theory that there are large bodies of mass "out there" that we can't see is true... if gravitation always attract... Would it not be possible for light to be bent in such a way that the observed vector of an object differs from the real one and the red-shift theory remains valid? What if dark matter is scattered in a non unifom way... Wouldn't that make our picture misleading?
Why do you still come here? It's because you're addicted. You have multiple accounts and getting them modded up is a rush. Trolling is a high art for you, as is misinformation, half-truths and outright lying. You have no life so you come here and bitch about /. and the editors/users/moderators.
What else is new?
Light is a rather strange beast - normal matter changes speed when energy is applied to it whereas light changes wave length (shorter wavelengths are higher energies).
Well, that's because light isn't matter, normal or abnormal.
This clearly is the result of the CD age, back in the LP age everyone knew you don't stack em flat, you store them on their edge to prevent warping. Just set the milky way on its edge and the warp will go away.
