This is historically game changing news.
[QUOTE=subenji99;37611471]Correct - the article makes no reference to how long light from the galaxy (and therefore the distance) has taken to get here, only the estimation of age of the galaxy.[/QUOTE] [url]http://www.space.com/16641-oldest-spiral-galaxy-hubble-telescope.html[/url] According to this article (space.com is, as far as I know, reputable) it's indeed 10.7 billion light years away.
Imagine the black hole at the centre!

A race of incredibly advanced aliens has created some way to hold their galaxy together to prevent the loss of their planetary colonies.
[QUOTE=Electrocuter;37611810]A race of incredibly advanced aliens has created some way to hold their galaxy together to prevent the loss of their planetary colonies.[/QUOTE] Because, you know, their needs were so intense that they don't use city domes, planetary shields, or dyson spheres. They make [I]galaxy domes.[/I]
[QUOTE=zzzz;37610868]Why is this being rated disagree, it's completely accurate. Are you guys stupid?[/QUOTE] Not necessarily (however in this case I'm not entirely sure). On the extragalactic scale you can't just say there's a 1-to-1 relationship between distance and time (that being you can't say that something that is x light years away is also x years old) - for example, the universe is thought to only be 13.7 billion years old, however the observable universe is MUCH wider than 13.7 billion light years in radius; it's actually estimated to be about 46 billion light years in radius (and I can say with certainty that in terms of observation there is a stellar structure that has been detected 30 billion light years away). Inflation, bitches.
[QUOTE=mastermaul;37610321]We're getting 10.7 billion year old light. It means so shortly after the big bang it ended up so well formed. We're looking at it how it appeared 10.7 billion years ago.[/QUOTE] Pretty sure you're wrong, it's 10.7 billion years old. Your logic only applies if it's 10.7 billion lightyears away. [editline]10th September 2012[/editline] Space Ninjas!

I'm a total noob on this stuff please don't kill me!
[QUOTE=Grimreaperx1;37611522][img]http://www.scientificamerican.com/media/inline/grand-design-spiral-bx442_1.jpg[/img] Here is the actual false-color picture of the galaxy.[/QUOTE] Looks like a space worm.

I'm a total noob on this stuff please don't kill me![/QUOTE] Yes it would but that's not what the article says. The article says that it's 10.7 billion years old, and says nothing about how far away it is. BUT it seems there's some confusion floating about, not just here. [URL=http://arstechnica.com/science/2012/07/a-hot-young-spiral-galaxy-is-the-farthest-yet-seen/]This article[/URL] says it's 10.7 billion light years away, and claims that it is a young spiral galaxy. Someone didn't do their research? [URL=http://www.huffingtonpost.com/2012/07/19/oldest-spiral-galaxy-bx442-nasa-hubble_n_1685627.html]This article[/URL] says it's 10.7 billion years old. But it also says this; [QUOTE]BX442's light has taken about 10.7 billion years to reach us, meaning astronomers are now seeing it as it looked just 3 billion years after the Big Bang that created the universe.[/QUOTE] I guess what this means is that the galaxy is... Well, [I]at least[/I] 10.7 billion years old. We must assume that it was created before we observed it and after the Big Bang. That must mean it's somewhere between 10,7 billion years old and 13,7 billion years old. ?
that picture looks like the wallpaper on my macbook air :p
[QUOTE=SpartanXC9;37610304]I wonder what lives there if it still exists. Right now I'm picturing galactic empires and the like.[/QUOTE] A far time away, in a galaxy long, long ago...
I wonder how different space would look if light reached us instantaneously [editline]10th September 2012[/editline] [QUOTE=sltungle;37612252]On the extragalactic scale you can't just say there's a 1-to-1 relationship between distance and time (that being you can't say that something that is x light years away is also x years old) - for example, the universe is thought to only be 13.7 billion years old, however the observable universe is MUCH wider than 13.7 billion light years in radius; it's actually estimated to be about 46 billion light years in radius. [/QUOTE] The reason the 'observable' universe is thought to be 46 billion light years in radius is because we can only directly see the size of it as it was up to 13.7 billion years ago. 46 billion light years is it's estimated current radius An object which we're seeing 10.7 billion light years away has continued moving away from us for 10.7 billion years, basically
[QUOTE=RobbL;37613633]I wonder how different space would look if light reached us instantaneously[/QUOTE] We'd be blinded by the light coming from space.
It blows my mind that i am just a mere 20 years old, and that is all I've ever known. And i can look in the sky and see planets that are so far away it takes [I]light[/I] 10,000,000,000,000 years to reach us. My entire existence takes up only two digits of the end of that number. Makes you think of what else is out there but the light hasn't reached us yet.
[QUOTE=DeanWinchester;37613863]We'd be blinded by the light coming from space.[/QUOTE] How ?

I am English, we do the whole billion thing differently but i guess the Hubble would go through Americans so it would be the other version, my bad.
[QUOTE=BlazeFresh;37614060]I am English, we do the whole billion thing differently but i guess the Hubble would go through Americans so it would be the other version, my bad.[/QUOTE] well I'm estonian and I use milliards too for billion, but when talking about space we talking about thousand million, not million million.
[QUOTE=RobbL;37614035]How ?[/QUOTE] Well, if all light traveled instantaneously we'd be getting light from literally every possible direction meaning it would be like looking directly at the sun but the "sun" would be everywhere in the sky.
[QUOTE=BlazeFresh;37614060]I am English, we do the whole billion thing differently.[/QUOTE] Do we? A billion is 1000 millions wherever you are, afaik [editline]10th September 2012[/editline] [QUOTE=DeanWinchester;37614084]Well, if all light traveled instantaneously we'd be getting light from literally every possible direction meaning it would be like looking directly at the sun but the "sun" would be everywhere in the sky.[/QUOTE] Still don't get ya :v It'd just mean we'd see everything in space as it is this instant
Should we be scared?
[QUOTE=FreyasFighter;37614215]Should we be scared?[/QUOTE] Always.
Let there be light?
[QUOTE=RobbL;37614089]Do we? A billion is 1000 millions wherever you are, afaik [/QUOTE] Some systems have million, 10^6, billion, 10^9, trillion, 10^12 Others have million, 10^6, milliard, 10^9, billion (bi million AKA million x million), 10^12, billiard, trillion etc Here, try this [URL]http://en.wikipedia.org/wiki/Names_of_large_numbers[/URL]
[QUOTE=Doctor Dave;37610822]What if it's exactly the same galaxy as ours?[/QUOTE]Really huge mirror. [editline]10th September 2012[/editline] [QUOTE=RobbL;37614035]How ?[/QUOTE]All the stars in the entire goddamn UNIVERSE we would be able to see.
[QUOTE=usaokay;37610159]If we can find signs of alien life in that galaxy, then it's time for some outerstellar space sex.[/QUOTE] The amount of diseases we carry, and diseases aliens probably carry, would make human-alien sex impossible.

Just because the light would be instant doesn't mean it would be brighter
