Andromeda Devouring Neighbor Galaxy

Soulskill posted about 5 years ago | from the om-nom-nom dept.

Space 60

Scientific Ninja writes "Astronomers in the University of Sydney have captured pictures of a 'union' between our closest neighboring galaxy, Andromeda, and its smaller neighbor, the Triangulum Galaxy. Published in the journal Nature on September 3rd, the research shows how large galaxies grow by incorporating stars from surrounding smaller galaxies. This popular model of galaxy evolution, called the 'hierarchical model,' predicts that large galaxies such as Andromeda, which can be seen with the naked eye from the northern hemisphere, should be surrounded by relics of smaller galaxies it has connected with."

This is just a model for one galaxy nomming another. God - whether such an entity exists or not - has nothing to do with it, it's an entirely natural motion, predicted, expected, and surprising no one with sufficient education.

our universe makes sense.

Whether or not this is due to god's existence or the clever realization that we wouldn't be here if it didn't is a religious question. However, I'm pretty sure that if God DOES exist, He definitely has something to do with two galaxys colliding -- He either purposefully caused them to collide as a means of saying "hi", or He wrote the rules that cause them to do so.

    If "god" is a factor in random events happening in the universe, next time you buy a lottery ticket and lose, or find your home galaxy is being engulfed by another galaxy, you have someone to blame.

    It's always good to have someone to blame, rather than accepting the fact that random events do happen. And yes, it was "god" that made the bird shit on your car today, just after you washed it.

    Now, if I was able to take a ship to observe the collision, that would be awe inspiring, but would not make me believe in the mysterious invisible entity in the sky of your choice. And, regardless of which "god" entity you chose, you're then declaring everyone of a different belief to be wrong. That is, unless you're always right, and the universe is packed with souls that are obviously not as smart as you, unless they believe your way.

On a related note, as the number of independent countries are growing fewer as time goes by, are we headed towards a one-world government where one country gobbles up the rest? If a certain group of humans are trying to effect this change, why is not possible that a bunch of supernatural entities are behind this galaxy gobbling, or is just physics?

Re:Not quite (2, Interesting)

JWSmythe (446288) | about 5 years ago | (#29343883)

    Being that a blackhole is just a superdense high gravitational area, it's generally assumed that every galaxy has one at the center. Kinda like you expect a treat at the center of every tootsie roll tootsie pop. Every one I've ever encountered had one, but it's possible that there are some that don't. :)

If anything is surprising about this, it's the discovery that the disc of stars surrounding a galaxy can extend far beyond the bright, central disc.

I'd be interested to know if this additional, distant mass will effect any changes on our existing hypotheses for galactic formation and accretion.

I for one welcome our new carnivorous galaxy overlords ... or whatever that other puny galaxy is made out of.

But perhaps it's just some twisted form of galactic Darwinism, the weak die (or get consumed or whatever) while the big and buff galaxies prospers.

Alternativly perhaps space isn't even really endless at all but instead quite finite and Andromeda just needed some galactic lebensraum?

Just a few questions (3, Funny)

2) if it happened in this galaxy would it be subject to regulatory approval, and if so, under whose jurisdiction?

According to this: http://news.bbc.co.uk/2/hi/science/nature/7813635.stm [bbc.co.uk] , the milky way is roughly the same size as Andromeda. Therefore, we won't be devoured, it will be a nice and slow merging.

Re:onoes obama (1)

MillionthMonkey (240664) | about 5 years ago | (#29342855)

Obama is trying to justify this merger with an unknown anti-Christian Andromeda galaxy lying to us saying it's going to be a "nice and slow merge but one that needs to be done after getting input from every galaxy" which is of course a lie because the Milky Way and hence the U.S. is going to get devoured and to that I say we should not be showing weakness as a country and we should not be apologizing to strange galaxies invading our turf and we should certainly not be merging with them and extending health insurance to how many other beings might be in that galaxy given we don't even know how many so with this galaxy collision about to happen he can't even explain how he's going to accomplish health reform let alone a galaxy collision.

This is local. What's happening on a global (ok, universal) scale is that the universe is expanding and after 100 trillion years all the hydrogen will be used up and there will be no more stars (or at least very few of them) and 10^whatever years after that the universe will just be a bunch of black holes slowly oozing out Hawking radiation. Very bleak.

So says the species that still thinks there is "Dark matter" and "dark energy" out there somewhere.

Physicists don't like to dwell on this point when summarizing what their research accomplished, but we really don't know enough to be definitive about how the universe will evolve. To wit: our LOCAL time-cone appears to be expanding, and if (1) this observation is correct, (2) the universe is homogenous to our time-cone, and (3) there isn't some exterior force pushing us together, then we'll all wind up in a cold death in the end.

For all we know, the vacuum of space might just have a slight red-tint to it, causing this "red-shift" that makes us think the universe is expanding. It's not like we have rulers or anything.

A red-tint is completely different from a redshift. The rulers are the hydrogen (and other elements) spikes in absorption spectra received from distant starts/galaxies/quasars... But you are right that this dark matter debate is one of the most mysterious in science today. We are in a similar position as with the 'unexplainable' results of the Michelson-Morley experiments over a century ago. It will probably get solved by a guy saying: "Look, it's really simple, just consider this..." like Einstein did with "the speed of light is fixed, no matter the referential... and here are the consequences"

You don't seriously believe this has started overnight, do you? The aggression has been going on for some time, but now that Democrats are in charge it has become an issue. The republicans ignored it, and the democrats are just now able to make a big deal out of it. Its like bullying in the elementary schools -- its always been there (and will be for a long time), but now it is no longer politically correct in the Liberal minds.
