- inactive, on 02/13/2008, -3/+69I wonder if something at that Galaxy is looking back at us, saying the same thing
- duk0r, on 02/13/2008, -3/+36Perhaps. But what about the galaxies I see behind it?
- inactive, on 02/13/2008, -4/+31Here, let me save you some embarrassment. I'll add this for you.
"/ sarcasm" - inactive, on 02/13/2008, -4/+30According to http://en.wikipedia.org/wiki/Age_of_the_universe, the age of our universe is about 13.7 billion years. And this galaxy has shed its light for 13 billion years already. Assuming our expanding universe takes this galaxy with it (as in the Big Bang theory), I guess this galaxy is almost at the edge of the universe. Ok, lucky for all those advanced civilizations living in there. They might have traveled to see what's at the other side of the universe already. Imagine being just a few feet from the very edge of the universe... Will you dare to walk right out of the universe?
- Vesper73, on 02/13/2008, -11/+37The Earth is only six thousand years old.....
- tao52nyc, on 02/13/2008, -0/+21The real mind-blowing part is that, given that the light took 13B years to reach us, that is what the galaxy looked like THEN. It may not even exist, now!
- tringtring, on 02/13/2008, -1/+20Just thinking about the distance - 13 billion light years - for a moment simply overwhelms me about the enormity of our universe...
13 billion light years, hmmm... - skase, on 02/13/2008, -0/+19artist's impression. I assume thats us behind it.
- kingmanic, on 02/13/2008, -2/+15It doubles back on the other side. It wraps around.
- NoCt1, on 02/13/2008, -0/+13coming from 13 billion lightyears.. Then we must be pissing some one off..
- wushu18t, on 02/13/2008, -1/+13i hope there's a restaurant there...
- lpmiller, on 02/13/2008, -0/+10The universe is ever expanding. Even if you were right "next door" to the edge of it, you could never reach it.
- inactive, on 02/13/2008, -0/+10or is it? What if they are alien battleships coming our way?
- AndrewBaron, on 02/13/2008, -1/+11Human beings are pretty clever for being able to see that far.
- inactive, on 02/13/2008, -0/+9Only a small population of the human beings like .00001%.
- nicksauce, on 02/13/2008, -1/+10*Edge of the observable universe. The universe itself could be much larger, as there is nothing stopping space from expanding faster than the speed of light.
- NoCt1, on 02/13/2008, -7/+16And again. Every time an article about space comes up there is this same comment posted.................Yes there is something looking back at us.. You think we are alone?
- yohnstoppable, on 02/13/2008, -0/+9I thought his comment was funny, regardless. If he wasn't sarcastic it would just be for different reasons
- xombiefarts, on 02/13/2008, -2/+11Hopefully be the time our radio signals reach that galaxy Duke Nukem Forever will be released.
- floridiot2, on 02/13/2008, -4/+13Can't possibly be. Remember, Earth is only 6000 years old. Light takes 13 billion years to reach us. Gotta wait over 12 billion years for them to see us. :)
- inactive, on 02/13/2008, -3/+12A long time ago in a galaxy far, far away...
- CountryTime, on 02/13/2008, -0/+8you'd have to send a space ship and let people live on it for 185 million generations just to reach it.
- Sikarian, on 02/13/2008, -0/+8Circle jerk each other later, guys. We're talking science here.
- BruceBogtrotter, on 02/13/2008, -0/+8God put those there to test our faith.
/sarcasm - InternetRules, on 02/13/2008, -0/+8In 1 second light travel ~ 7.5 times around the earth. There are 409968000000000000 seconds in 13 Billion years
- scrimaxinc, on 02/13/2008, -1/+9He said "that Galaxy", jerkface. I think it's a reasonable thing to ponder. Who's to say that galaxy even exists anymore? Supermassive blackhole FTW.
- 1807, on 02/13/2008, -0/+7See what you can do when you don't have a woman to tie you down?
- AntBing, on 02/13/2008, -2/+9What a great time to be alive. Science rocks!
- ccfoo242, on 02/13/2008, -0/+7What confuses me is if it's light took 13B years to reach us and the universe is 13.7B years old then doesn't that mean we somehow got 13B light years away from this galaxy in under 13.7B years? So if we all started from the same point (big bang) then we would have to travel at almost the speed of light for half that time assuming we were traveling in opposite directions. Right????
- sjbdallas, on 02/13/2008, -2/+9If we start now, we should get there just in time for the universe to collapse.
- zephc, on 02/13/2008, -0/+7The author of the article was channeling Professor Farnsworth, apparently.
Good news, anybody! - shadowblade989, on 02/13/2008, -0/+7Wow....
"The discovery was made possible by a natural magnifying glass -- the galaxy cluster Abell 1689, which lies between us and the distant galaxy. Abell 1689's gravity is so strong it bends light that passes near it, acting like a giant zoom lens that magnifies what we see."
Amazing - inactive, on 02/13/2008, -0/+7Multiple personality disorder?
- nicksauce, on 02/13/2008, -1/+6"The expansion of the universe causes distant galaxies to recede from us faster than the speed of light, if comoving distance and cosmological time are used to calculate the speeds of these galaxies. However, in general relativity, velocity is a local notion, so velocity calculated using comoving coordinates does not have any simple relation to velocity calculated locally.[17] Rules that apply to relative velocities in special relativity, such as the rule that relative velocities cannot increase past the speed of light, do not apply to relative velocities in comoving coordinates, which are often described in terms of the "expansion of space" between galaxies. This expansion rate is thought to have been at its peak during the inflationary epoch thought to have occurred in a tiny fraction of the second after the Big Bang (models suggest the period would have been from around 10-36 seconds after the Big Bang to around 10-33 seconds), when the universe may have rapidly expanded by a factor of around 10^20 - 10^30"

- turbopro, on 02/13/2008, -1/+6thats an artist rendition, where are the real pics?
- Chainheart, on 02/13/2008, -0/+5Actually, the .... almost made it look serious
- vertigoblue, on 02/13/2008, -0/+4pft... I could do that over the weekend.
- 1807, on 02/13/2008, -0/+4you smoke weed don't you.
- Innisskillin, on 02/13/2008, -0/+4Road trip anyone? I'll bring snacks.....
- yohnstoppable, on 02/13/2008, -0/+4Ow! My brain :(
- ryan83189, on 02/13/2008, -0/+41.65538555 x10^24 football fields.
- MeMongo, on 02/13/2008, -2/+6Yes, there is someone looking and his name is Xenu. He must be feared because his presence gives Tom Cruise the ability to heal and read minds.
- Matteos, on 02/13/2008, -0/+4I blame Bush.
- wellyuk, on 02/13/2008, -0/+4How do creation scientists explain stars/galaxies that are 13 billion light years away? I would absolutely love to read their explanation. If anyone has any references, can you post them? I'm very curious.
- fatTJ, on 02/13/2008, -0/+4well, isn't there a chance that galaxy isn't even there anymore, being that the light took 13 billion years to get here?
- courvus, on 02/13/2008, -0/+4you should have saved yourself the embarrassment of putting a space in there.
- Mootabolife, on 02/13/2008, -0/+4Actually, if the ship were moving at the speed of light, time would slow down. Our astronauts might be able to get there in minutes, but it would be 185million generations for the rest of us =-//
- hacman, on 02/13/2008, -0/+4Isn't there a restaurant out there?
- Sikarian, on 02/13/2008, -0/+4It brings up an interesting question. If scientists on a planet over there see our galaxy, the light from ours to theirs is 13 billion years ago and we are expanding away from them. What if they think that we are at the beginning of the universe? Or the edge, rather. That our galaxy might be the oldest. They might think on the other side of us is nothing, the same as we think for them.
