Crumb stars suggest Milky Way was cannibalistic

By Jessica Shugart, Special to CNN

Editor's Note: Jessica Shugart is a science communication graduate student at the University of California, Santa Cruz.

Billions of years after going on a cannibalistic binge, our own Milky Way galaxy has been implicated by the stale crumbs it left behind.

Astronomers at the University of California, Santa Cruz, used Hubble Space Telescope data to spot the crumbs - ancient stars thought to be remnants of a dwarf galaxy engulfed by our hungry Milky Way when it was still young.

The finding, to be published in the upcoming issue of "The Astrophysical Journal," supports the hypothesis that the Milky Way grew by pulling in smaller galaxies and claiming them as its own.

The researchers found the stars while looking at data from the Andromeda galaxy - the next big thing the Milky Way is destined to overtake. In about 4.5 billion years, the two are set to meet up and form an elliptical galaxy (Milkomeda?). In order for astronomers to focus on stars in Andromeda, they had to cancel out the annoying stars that orbited the outer reaches of our own galaxy.

"So when that [Andromeda] study came out, I basically asked them for their contamination," said Alis Deason, the postdoctoral researcher who led the new study.

The outcast stars exist among millions of others that form a loosely packed halo around the Milky Way. Whereas our solar system is roughly 25,000 light years from the galactic center, these castaways lurk at 80,000 light years from the core.

Deason and her team sifted through seven years of archival Hubble data to find the stars that others had thrown away. They hoped to identify remnants of a "galactic shell" - a structure seen around other galaxies that hints at a cannibalistic past.

"Basically, the halo is just a hodgepodge of stars that have come from other galaxies, usually dwarf galaxies," Deason said. "The reason these are interesting to study is they retain the memories of their initial conditions."

Ultimately, the team settled on 13 stars cruising along in the halo. That they existed there, along with thousands of other stars, wasn't the tip-off to their significance. Instead, their trajectories were what gave away their foreign past. Unlike other stars in the halo that move radially around the outer realm of the galaxy, these 13 stars appeared to hover.

"When we looked at these 13 stars, which are three times further away than it's ever been done, we found that the sideways motion was actually quite large," Deason said.

Their tangential motion hints that they were once part of another galaxy acquired by the Milky Way billions of years ago, like aimless minnows left behind after a whale swallows up the rest of the school.

"By looking at their velocities and their spatial positions, we can try to figure out what satellites these stars came from and when they came into the galaxy," Deason said. "It's a link to find out about the accretion history. That's why we study the halo."

These foreign stars will provide useful information about our own galaxy as well. Monitoring their movements, which are affected by the gravitational pull of our galaxy, could give us more accurate measurements about how massive our own galaxy really is.

Because most of the mass of our galaxy consists of dark matter - a mysterious form of matter that can't be seen - the dance of these straggling halo stars might hold the key to the big picture of our galaxy's composition.

Deason and her team stress that more hovering stars need to be pinpointed before our Milky Way's cannibalistic guilt is confirmed, but the existence of these 13 outliers hints at a halo of hidden clues about our galactic neighborhood's early days. Deason is hoping to acquire Hubble data from different fields and distances to ultimately rack up 600 to 700 halo stars for further study.

When the Milky Way and Andromeda cross paths someday, who knows whether own sun will get in line with the new galactic order or chart its own path in the halo, serving as an artifact for future astronomers?

    Fascinating information. The more MONEY the United States can put toward science and math the better off this country will be in the future. If anything, the budget should be doubled if not tripled on education, JPL and NASA. American has rallied around science before, why not again. Being the first to put a man on the moon and now we have sunk to the listing to a hack radio conspiracy theorist tell us about the Man in The Moon, how pathetic. The same guy claims every other day the sky is falling and the government is evil. The same guy who wont even say the presidents name any longer. If left to some in this country we would head in the exact same direction as the Taliban disregarding everything but religion. If anything religion has derailed America with the help of the GOP / Tea party fixating on non issues like abortion and gay marriage only to more these non issues to the front page. While new technologies, discoveries that motivate intelligent young minds are left out or replaced by a so called "Reality Show". The real reality is that the United States is slipping because of our incessant need to grow the economy via war and oil. Forgetting fortune is education, knowledge and exploration. Only a very, very narrow minded person fearful of his or her pastor may not agree. As for the second amendment, it may be important. It is certainly part of who we are as a country. But remember, even a moron can pull a trigger. I understand it is difficult, to think when you have NASCAR and the NRA on your mind, but the future is knowledge and that knowledge will not suddenly appear from some magic man in the sky, or the moon. It comes from hard work and dedication and a country willing to explore and learn. Just because YOU can only imagine survivalist camps, the fall of our nation, guns and countries over running our borders does not mean that is what you have to pass on to your children. They would be better served learning and creating ways of dealing with these things in ways you could never imagine, but most will not get the chance because of fear. A fear created primarily from the GOP / Tea Party. They name every generation, I wonder what the up and coming generation will be named, war mongers, because their parents taught them to hate the government, and the president and the only answer is to pick up a gun. Or will they see past this and actually look for something that will help the nation like education, knowledge, exploration ? Think about buying a book and a telescope instead of an AR-14 or a Glock, chances are good your kids will learn a lot more. That education and experience will take them a lot more places and make them alot more MONEY that a gun will.

      What in the world is this rant? You make no rhyme nor reason. You jump around as if you want to talk about everything and nothing at the same time and succeed on the Nothing point.

      If someone wants to study this, OK by Me, but, on your own money not the taxpayers. This is nothing more than the taxpayers paying Millions of dollars on some professional students personal hobby. They look at things Billions of years ago and don't even know where they are at today since we we measure distance in Light years. Are you telling us that the Universe is an intelligence? If so, are you proving the Existence of God? Seems like the way the article is worded that this is the case. The Milky way is an intelligence and therefore our god exists therein.

    If these stars in the shell are remnants of another galaxy that collided with ours, it's hard to imagine they came through it entirely unscathed. The stars may have survived, but with damage. And any planetary systems they had would likely have been severely disrupted, or even destroyed utterly. It's hard for anything much to survive, unharmed, two galaxies in collision.

    So there had to be damage done to many stars in our OWN galaxy, too. But what? What should we look at to find the damaged ones?

    Also, I know of nothing that points the finger at any particular object in the cosmos that collided with our galaxy. The prime suspect, I should think, would be the Magellanic Cloud. But there is no study to find our recent too-close romance with a galaxy. I could be wrong, but does anyone know of any studies about that?

    This article set me to thinking about this and other things, too.

    I'm well-read on astronomy, but by no means a scientist. So I could be wrong about some things.

    It's my understanding that Andromeda is moving toward us. Which means it is red-shifted. I also understand that the universe not only appears to be expanding, but that the farther something is from us, the FASTER it is moving away from us (blue-shifted). To my knowledge, this is a genuine rule-of-thumb that applies to every known celestial object. I am still curious as to how that is so, however. I haven't encountered an explanation for the phenomenon; I just know it is applicable everywhere in the cosmos. And not just from our own perspective; the expansion, from any viewpoint in the cosmos, is the same. Meaning that all objects in the cosmos are actually moving away from all the others, like dots painted on a balloon which is then inflated, so each dot grows farther away from all the others. I don't think scientists claim that the REAL velocity of those distant objects is as fast as their blue-shift implies. There is something about distance that makes their velocity appear to increase. When that apparent increases to the point where it reaches the speed of light, the object would "fall out of the universe," from our viewpoint, since its light would have to exceed light speed to reach us at all. I've often wondered at this, and wish I knew more about the phenomenon.

    Apparently, though, in local groupings, things CAN move toward one another, like Andromeda approaching us. Are WE also approaching it? It's hardly likely to be otherwise. At what speeds are each of these galaxies moving toward one another? It's hardly likely that we are sitting still while only Andromeda is on the move toward a meeting of the two galaxies.

    In addition, I understand that Andromeda is much larger than our Milky Way Galaxy. In which case, wouldn't a collision of the two result in a bigger Andromeda and with our galaxy mostly shredded? Not that it's anything to worry about for the next few billion years, but I crave to know!

    So that begs the question: Is the velocity of Andromeda's approach to us decelerating? Since it gets closer, rather than further away, its speed ought to be declining, if the relation between distance and velocity is uniformly applicable. Can anyone give a scientific answer to that?

    Then there's the Magellanic Cloud. The article didn't mention it, but it said our next collision will be with Andromeda, which is still VERY far away. Why not the next collision with the Magellanic Cloud? It is a small galaxy in its own right, and is relatively near to our Milky Way. In which direction is it moving? Toward us or away from us? If toward us, isn't it likely to collide with our galaxy in a statistically provable time frame, very MUCH sooner than Andromeda? If away from us, is it possible that it is the remnant of the last galactic collision our galaxy experienced? Of course, it could be traveling transversely with relation to our galaxy, but what about gravitation? Wouldn't the mutual gravitational pull alter such a course? And in doing so, it would not make the two galaxies separate; it would pull them toward each other. Unless, of course, they'd already HAD a collision? It seems to me as though the Magellanic Cloud is rather severely under-studied. It was the study of it which first revealed the nature of Cepheid variable stars. But nothing much has come from study of it since, to my knowledge.

    I'd like to know if there is any prediction about collisions, with either Magellanic Cloud or Andromeda. At what angle would the collision occur, and what involvement would each core of each galaxy have on the other(s)?

    I can't begin to give answers to these questions. Only a genuine astronomer can do so, but lay people who have access to the specific scientific knowledge I am seeking may be able to convey it to me.

    I'm very curious about these things.

      I heard an analogy that when two galaxies collide the likelihood of stellar collisions is similar to two fly's colliding in the Grand Canyon. Things only look dense. There are many examples of galaxies colliding in the universe.

      March 7, 2013 at 5:36 pm |
      • H. B.

        This is true. If you only look at the distances between stars and don't look at the likely gravitational effects. Those are likely to be profound, whether they result in stars colliding or not.

        Oh, a small errata. I spoke earlier about the Magellanic Cloud. I'd forgotten that there are two of them. They are, most likely, closely related in many ways, though. Perhaps both are remnants of the earlier collisions our galaxy has experienced. Maybe it broke another galaxy into two pieces. I don't claim to know.

        We have photos from our best telescopes showing a large number of galaxies in collision, and many others who are about to have one, or just separating again after one. They're all different. In some, there are awesome effects, where, very likely, the black holes at the centers of two galaxies crashed together, sending huge jets of energy outward. In others, the galaxies seem to be passing through one another calmly. There's no way to know how calm they really are without much more study.

        If I remember right, our galaxy supposedly has about 140 billion stars. Andromeda is bigger, so it would have more than twice that number. When the two collide, it won't matter much that most stars hit nothing. It's inevitable that many WILL strike other stars. It doesn't need much to cause great disruption in either or both galaxies. They will be affected by gravitational contradictions, just for starters. So hitting something isn't the only way damage can be done.

        If a planetary-sized mass went past Earth, even if it didn't touch it, the gravitational forces could alter Earth's orbit, spin, axial tilt, and many other things. It could pull the moon away, or pull the moon toward Earth, depending on where it was when it passed by. Similarly, the Earth's own gravitation and momentum would have effects on the approaching body. Without something real happening, we can't guess at possible outcomes, except that if the approach is close enough, it wouldn't be pretty.

        Collisions aren't the only nasties that can result when two galaxies collide. But some nasties are bound to be inevitable. All we can discern are the visible effects. Visible across millions of light years. It doesn't require that all stars, or even most stars, collide. A few can cause great disruption, and conflicting gravitational effects may do even worse damage. It is still quite safe to assume that a galactic collision would be bad for both. At least from our human and life-oriented viewpoint. Life in either galaxy would be in grave danger.

    • robert

      Stars are so far apart in galaxies that it is highly unlikely that the stars in two colliding galaxies would collide with each other. They would certainly be affected by each others gravity, which might stimulate star formation, but you are not likely to see many bumps or bruises. Think of it like two people walking from one city to another. Even if their paths cross, their chances of bumping into each other is still very low, but likely much greater than two stars colliding.

    • Gerald

      Slight correction, objects moving towards your perspective are blue-shifted, while objects moving away are red-shifted. This is the Doppler effects as it applies to light and sound. Scientists can calculate velocity from the degree of which the light is shifted given the distance from the source is known (which it is) As for galaxies colliding, even though there are billions of stars in each galaxy, there is so much space that most of the stars, in both galaxies, will not touch each other. The gravity interactions between all the objects is what will drive the galaxies into an elliptical shape.

    • DaveW

      Galaxies which are moving away from us are red-shifted. Galaxies which are moving toward us are blue-shifted. Andromeda is blue-shifted.

    • John S

      Objects farther away from us (as delineated by light-years) are older and represent the edge of the universe. The edge of the universe can expand at an increasing rate, but that doesn't have an effect on the objects in the middle of the universe. You could put two marbles in the middle of an expanding balloon and the marbles won't move or be affected in any way by the rapidly expanding balloon around them. I hope that answers your question.

      The article didn't say it was a photo. It is an artist's rendering.

      Many scenarios in space are done by artists; it's common practice. When something really IS a photo, your best clue is the credit given to the telescope (more often than not these days, it is the Hubble) that took it.

      We can't photograph many things in the cosmos. But photos are usually clearly marked as such. For the rest, artists' renditions are the best we've got.

      You may not realize it, but your comment was a great compliment to the artist who produced the picture. You couldn't tell his artwork from reality!

      If you really ARE interested in these subjects, I'd recommend you get the book, "The Universe: from Flat Earth to Quasar," by Isaac Asimov. It may be decades old, but almost all of it is still valid. In the book, he WALKS you through the scientific concepts of astronomy, so the next chapter can build on that new knowledge you've acquired. He isn't called "The Great Explainer" for nothing. That one book got me started as an "armchair astronomer," and I was able to increase my knowledge from there. If you want to get the book and read it, I can envy you for the joy of reading it for the first time. It uses very little math, but gives a sturdy comprehension of the principles of astronomy and of the basic attributes of the cosmos. I know of no better introduction to the subjects.

      The Ancient Egyptians had this idea on how the universe was created and I find it rather fascinating. Once you strip all the religious mysticism from the story you find out that they viewed the our existence as coming from a vast and immeasurable body of chaotic water which was invisible and unseen (a metaphor for the dark unseen matter which fills the gaps between stars perhaps?) Existing in isolation within this dark chaotic sea were eight forces, all representative of the characteristics of this dark sea. Four of these forces were of male essence and the other of female essence (perhaps another metaphor to show that some of these forces were dominate and more forceful over others which are more nurturing and creative?). Once the pairs came together they ultimately created the FOUR main forces which are the key to the universes existence. After their unions, by the way of the force of the 'Hidden One' (and no, this does not refer to god, but rather the main energy which keeps all in motion and existence) came together in a massive eruption which caused the creation of a hill (thus representing our planet or galaxy etc).... The Egyptian Creation myths go on from there and intertwine to explain the formation of the earth itself, creation of all living things, and even the destruction of our sun. While their finding aren't and perhaps cannot or shouldn't be classified as scientific, what was ancient religion but a tool to explain the forces at work in our universe? Funny to think our ancient ancestors had such insight.

      So to say religion is without meaning or detrimental to the understanding of our universe I feel is inordinate. The fact that we cannot accept that neither religion nor science holds all the the answers is detrimental. Religion, as it exists today in the form of books, hymns, psalms and radicalism is what is hindering faith as being part of scientific exploration. What is in scripture is man made and does not display the true meaning of religion. Religion is not the belief in magical beings or one super dude who is in charge of everything. Religion is the embodiment of exploration and the examination of the unknown, a tool to discover how forces work and interact and a way to revile that which is yet to be explored.... or is that science. Ma'at.

      • Andrew

        Einstein was rational and open minded when he was young, but as he aged, he rejected much of quantum mechanics. Much of that was because his philosophic need for a perfectly ordered universe as described by GR didn't mesh with the chaotic unpredictable nature of quantum mechanics. Einstein liked determinanism.

        In the end, he became like Planck before him, doomed to obey Clarke's first law. "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."

    Nothing like the News Media to try and inflate the importance of a story. It has been generally known for some time that relatively large galaxies like the Milky Way eat smaller galaxies. Currently the Milky Way is in the process of eating the Sagittarius Dwarf Galaxy. Stuff like this just bolsters the proof that the Milky Way has eaten other galaxies.

    Also, the most likely result of the collision of our Galaxy with the Andromeda galaxy is not another larger spiral galaxy but rather an elliptical galaxy.

      @Peter you sir are horribly misguided. Yes learning our earth is important, but space exploration is just as, if not more important. First on a tangible level, between astronomy and the space race, look at all of the technology and jobs that were produced. From a pragmatic standpoint, we have all of our eggs in one basket, and on top of that are overpopulating, polluting, and destroying the planet. We need a hard drive back up so that in the even of an "end of the world" scenario, it's also not the end of mankind. So to recap, jobs, technology, and sustainability are all positive byproducts of studying and traveling to the cosmos. Even Stephen Hawking agrees (and he is signficiantly smarter than either of us)

        To be fair though, the government insures the money you put in the bank up to $250,000. Had they not bailed them out they could have potentially paid a lot more out to the american citizen than what they spent bailing out the banks. Plus the problem with getting each person their money would have been next to impossible and probably pretty disasterous. One condition to the bailout should've been fire all your higher ups and do it better next time.

I don't remember the name of this man – who knows? maybe he is/was an eccentric scientist with no credibility, but this CNN story makes me want to look into this theory a bit more. Anybody have a galactic star cruiser I can borrow for a while?

    March 7, 2013 at 12:15 pm |
    • Chris

      I understand what you mean but logically I don't see any reason this would happen. Gravity is relative to mass and density so if an object leaves a galaxy and is in dead space; that object is then the main gravitational attraction and is thus generating force inward still and should remain intact. However objects generally don't become spherical until there is enough mass to do so; given this, an object with little mass/density of certain material could behave differently but I don't see any reason it would separate without external forces. It has been a while since class (I have a degree in space studies) but based on what I learned my above explanation should hold up as a decent generalization.

      March 7, 2013 at 12:42 pm |
    • Aezel

      The four forces that hold our universe together (well, as we currently understand it) are the strong, weak, magnetic, and gravitational forces.

      Gravity is by FAR the weakest of the four. It attracts one clump of matter to another but it by no means is what holds structure together at the quantum level.

    The 'Milky Way' is nothing but a conjured-up 'image' by those who profess to be 'scientists', but in truth are actually 'scientific pawns' wholly engaged in their comical 'theories' of the universe. Since the Copernican theory is nothing but a myth, then indeed these folks, like Nick himself, have in effect duped themselves in this non-scientific 'ecstasy' conjuring up more fanciful ideas of our 'origins'. Yet the real 'pushers' of the dupe is NASA, who along with the Soviets, conjured-up 'human spaceflight' after they discovered that they cannot 'land' any vehicle from hypersonic w/o vaporizing. Hence, the fake lunar landings (coordinated by the two) have led up to the rest of their fakery, including the Hubble, which is nothing but the grandest scientific fraud in history, which is about to topple as detailed in Revelation.

      You're a p'taK of the highest order. It is also intuitively obvious, even to the most casual observer, that you distrust any form of science. If you step outside on a cloudless night, away from the optical pollution of any cityscape, you can see the Milky Way. How does what you can see with your own eyes correlate to your statements? Copernican Theory? Where did you see/read THAT? I've enver seen it referenced as such. So you'd prefer the view stated by the Church for eons, that the earth is not only the center of the solar system, but the universe as a whole? What hubris !! Orbital mechanics (math, for the unintelligent, uninspired and unknowning) proves your statements false. Anyone that thinks that the moon landings were falsified is truly delusional. If that were the case, how, then, can you actually see the decent stage of several LEM's on the surface of the moon? Huh? Inquiring minds want to know. Your hypothesis that one cannot decelerate from hypersonic velocities without vaporizing indicates you have zero understanding of thermodynamics. I've seen the Apollo Eleven, Thirteen adn Sixteen capsules, all safely returned from orbiting the moon and returned safely to earth. The evidence proves your ignorance. And Revelation is a myth, created to dupe the unknowing into fearing "The End" ... Let me tell you something, Pilgrim ... our sun, Sol, will go Red Giant in about 4.5 billion years, about the same time that Andromeda will collide with the Milky Way. Too bad, that ... the sight would surely be magnificent !! So go crawl back under your rock ... and for Pete's sake, DON'T REPRODUCE !! There are enough ignorant p'taK on this rick as it is.

        Interesting..... You might want to add a few additional exclamations behind your statements, that way you will 'prove' me wrong.... But truly, as you're obviously in torments because anyone who actually thinks that NASA 'landed' on the moon inside the 'three foil thick' engineering p.o.s. truly needs to get a grip on reality. It's blatantly obvious that the entire 'space race' was nothing but a grand master-minded con conjured-up by the Nazis, and paid for by the American tax payer. Now then, since NASA and the CCCP went to extreme measures to con the masses regarding the lunar landings (filmed at Groom Lake), then you sure as heck can bet the rest of their 'space travel' show is nothing more than a brainwashing scheme with the overall intent to strip away biblical truth (whether or not you believe in God is not the point, yet Apollo is indeed Satan the liar). My point here is that the 'master-mind' of NASA is to promote scientific fraud. So perhaps you should do this... go outside and stare at the sun. After the days end, if your eyes have not burned out of their sockets, record what you observe. Then do the same for the remaining celestial bodies. If you're an astute observer, you will notice that the moon does not orbit west-to-east (unless you're drunk on moonshine...). And then you can go from there.....

Because if you did, then you would quickly realize that "special plastic" used for NASA's alleged "heat shields" is nothing but a farce. Hypersonic reentry = vaporization = end of 'spaceflight'....

So who pulled off this great hoax, no not some country, tell who as in the people that done it/ How many Hoaxters were there, where were they located, how did they mess with Radars on several continents all at the same time, How did they mess with all the computers and keep the hoax in sync? You have no Idea of the complexity of the space program nor the people who work in it.

    "the Milky Way grew by pulling in smaller galaxies and claiming them as its own." You earthlings have this strange habit of giving inanimate objects earthling-like characteristics.

        Some people also use lies in the same way. How about just plain provable facts instead of Metaphors?

      Anthropomorphism. It's why God was created in our image.

    I'd say the Milky Way was predatory rather than cannibalistic. Not too surprising since we can directly observe other galaxies colliding at various stages. Once again we find our world is in family.

      We were totally just defending ourselves. There we were just spinning away when BAM! Another galaxy sideswipes us, I mean come on, what were we supposed to do just sit there and take that? Jeesh. So we ate them . What ever. It happens.

        sadly, I don't believe it is sarcasm. Go google the religious nutball that's convinced the Big Bang was faked because there's no video of it.

      • starstruck

        So you are convinced it happened BECAUSE there is no video?

        Its a theory, you know. Just as relevant and irrlevant than any other. If you buy into it lock-stock-and-barrel you are zealot just like any religious fanatic. WE DONT KNOW. This is what a real scientist would say.

        There is astronomy data that sees clusters of galaxies at the edge of our view that has them moving around a different center. This could shake up the whole big bang theory.

      • I'm The Best

        Starstruck,
        You're right, we don't know, and it is just a theory. But it has more supporting evidence than any other theory which is why so many people believe it. There's the Cosmic Microwave background radiation, the Hubble constant/expansion of the universe, etc... Other theories don't have as much going for them as the big bang does. So people who understand the reasoning behind the big bang aren't like religious zealots at all because there is a data that supports their viewpoint. As opposed to some religious people who stick with god creating everything where the only evidence is in a 2000 year old book that no one can agree on the meaning and many people believe to be false.

        My point being that people believing in the big bang have more reason than most to believe in it, the theory is backed by observations and data.

      The sun will burn out in about 7 billion years, the galaxy collision happens in about 4.5 billion years, but the sun will already be too hot for the earth in about a billion years.

      • MadDog

        "Burn out" is a relative term. Sol is expected to burn through its supply of hydrogen and helium in about 4.5 billion years. After the Red Giant collapses, it will be a brown dwarf for billions of years more until, finally, it has cooled enough to no longer radiate. But 7 billion? Nah ... that number doesn't jive with the Red Giant or Brown Dwarf phases ...

  44. Mr. Dood2u

    I have never accepted the idea that two spirals meeting will therefore produce spiral offspring. I do not believe we have anywhere the required knowledge concerning gravitational distrubutions in intergalactic space to even remotely know what two spirals will do even if they are in the same inertial frame and rotating identically which is the simplest possible orientation to set up a model..I NEED WARN ALL OF YOU THAT YOU HAVE A TIME SPAN SO SMALL COMPARED TO GALACTIC EVOLUTION THAT ITS HONESTLY ABSURD FOR YOU TO PRESUME YOU CAN TELL THE OUTCOME OF SUCH PROCESSES WHICH MIGHT TAKE BILLIONS OF YEARS TO DEVELOP. Considering how difficult it is to establish the multibody problem of gravitational dynamics I think all of this must be likened more to a computer book on fiction than real knowledge..and that's ok...that's great even...just dont lose the ultimate perspective...which is that WE ARE REAL REAL REAL REAL REAL REAL.....SMALL!!!! no smaller still ......

      Oh dear.

      Argument from personal incredulity is not exactly a position of strength. Just because you don't understand or know how to perform a simulation doesn't mean none of us do.

      March 7, 2013 at 10:49 am |
      • starstruck

        Thats right. Most of us simulate knowledge on a regular basis. And we are so sure we are right!

        March 7, 2013 at 12:37 pm |
    • Chris

      Your arguement made a point that we can't know because it takes billions of years to happen. The reason we look around at all the areas of the universe however is because the night sky for us is like looking into a window to the past. And by looking through that window and seeing every diffent type of thing as it happens or prepares to happen or finishes happening we can make an educated guess of how similar systems will behave.

      March 7, 2013 at 12:50 pm |
    • Shane

      We don't know for sure, this is also not a scientific journal and basic mistakes are going to be made.

      And the minor detail on whether or not it will turn into a giant spiral (author was probably just making a guess) doesn't really negate the rest of the article.

      Our universe lovers making disc out of stellar objects. Think of it this way gravity wants to pull every star close to every object. In galaxies gravity wants to pull everything into the smallest space possible, but the velocity of stars makes them form orbits instead. However even if gravity can't pull everything to the center, it still will makes the most compact formation it can, which is a disc.
